IDENTIFICATION
The subject of standardization of herbal drugs is massively wide and deep. There are many
seemingly contradictory theories on the subject of herbal medicines and its relationship with
human physiology and mental function (Yadav et al., 2011).[29] Quality Control of crude
material / raw material:“Quality” is the sum of all the factors which contribute directly or
indirectly to the safety, effectiveness & acceptability of the product.“Standardization”
describes all measures taken during manufacturing process to obtain the desirable quality.
Thus the “Quality Control” leads to reproducible of a particular product in desirable manner.
“The Quality criteria for herbal drugs are based on a clear scientific definition of the raw
material” It is the key step. Taxonomic identification and authentification of raw materials
macroscopically and microscopically have to be evaluated. Depending on type of preparation
and matrix of the finished product, physico-chemical parameters such as LOD, Ash values,
Extractive values, pH, and Sap value, Acid value etc; have to be observed. Adulterations have
to be checked to prove identity and purity of a raw material. Microbiological contamination
and foreign materials such as heavy metals, pesticide residues, aflatoxins & radioactivity are
to be tested for further quality. To prove the constant composition of herbal preparations or to
obtain a reproducible product adequate analytical methods have to be applied for active
principles for known or unknown to Standardization or Normalization to check the criteria of
uniformity (Narasimhaji V. 2018).[20]
According to the WHO, the quantity, quality, safety and efficacy data on traditional medicine
(TM) are not sufficient to meet the criteria needed, so some of the major policy challenges
include safety, efficacy, quality, and enlightened the perception for the use of TM. Various
policy measures have been applied for a clear eyed view of the use of TM, in order to

increase its safety, efficacy and acceptability (G. Bodeker and G. Burford, 2007; Sagar et al.,
2023a&b).[5][6] Historically herbal medicines have played a significant role in the
management of both minor and major medical illness (Bahuguna et al., 2014).[23] In order to
obtain assured quality based herbal products, care through pharmaco-vigilance and utmost
care has to be taken right from the beginning i.e. proper identification of plants, season and
area of collection, grading, drying, extraction, purification process and rationalizing the
combination in the case of poly-herbal drugs (Patel et al., 2006; Sagar et al., 2023a&b).[5][6]
The Standardization and Validation of ASU herbal Drugs is not an easy challenge as various
factors influence the bio efficacy and reproducible therapeutic effects. Validation of
pharmacopoeial standards by experimentation and observations provides a set of
characteristics to a particular herbal medicine. Therefore, Scientific Validation of Unani
Formulations is an important tool used in the standardization process. (Kunle, 2012).[27] As
there is increase demand of herbs and herbal products especially Unani medicinal products,
run across many problems like non-availability of good quality of raw materials, proper
methodology for standardization. In consequence to ensure and develop the quality,
authenticity of Unani formulations, the standardization of single as well as compound drugs
on modern analytical parameter is basic requirement for drugs. Before studying
phytochemical and pharmacological activity of any drug physico-chemical characteristics is
necessary for it’s authenticity (Naaz A et al., 2021).[12]
The quality assurance and quality control of herbal crude drugs and formulated products are
important in justifying their acceptability in modern system of medicine. Hence it is required
to conduct the research on drugs standardization and product validation to provide effective,
curable and safe drugs to the needy mass suffering from various ailments.(Sagar et al.,
2024a&b; 2023 a &b; 2022b; 2021; 2020a&b; 2017).[1][2][8][9][13][14][15]
Dhataki / Dhayphool / Gul-e-Dhawa plant is a very effective medicine. According to
Ayurveda, Dhataki is beneficial in the treatment of many diseases. You can benefit from
Dhataki in diseases like bone disease, ulcer, fever, diarrhea and piles. Many types of
medicines are made from Dhataki plant. It is such an important plant that Dhataki flowers are
used in almost all Ayurvedic extracts or juices. Dhataki has been used for research and other
activities for many years. Let us know in which diseases Dhataki is beneficial. (dhataki plant)
is of medium height. Its average height is about 3.6 meters. It is a plant rich in medicinal
properties. All parts of its root, stem bark, creeper, leaves, flowers, fruits etc. are beneficial.

Various diseases are treated with Dhataki. Dhataki plants are filled with flowers every year
during January to April. At this time its leaves fall. New leaves appear in its plants between
February and March. Dhataki flowers are bitter in taste, cold in nature and small in size.
Dhataki flowers / Gul-e-Dhaawa are helful to joining bones (Anonymous, 2021; 2011).[10] [27]

Pharmacopoeial standard parameters
Pharmacopoeial research studies such as organoleptic characters, microscopically,
macroscopically and physicochemically, TLC/HPLC fingerprinting, quality control and
quality assurance parameters were carried out
1. Organoleptic evaluation: Organoleptic evaluation refers to evaluation of formulation by
colour, odour, taste, texture etc., using the sensory organs of our body. The organoleptic
characters of the drugs samples were carried out based on the method described (Siddique
et al., 1995; Sagar et al., 2024a&b; 2023 a &b; 2022b).[1][2][8][9][13]
2. Powder microscopy: Take 3-5g powder drug sample was weighed, mixed with 50ml of
distill water in a beaker and warmed gently in order to make complete dispersion in
water. Then mixture was centrifuged and decanted supernatant. The sediment were
washed several times with distilled water, centrifuged again and decanted the supernatant.
Small quantity of the sediment was taken and mounted in glycerine, out of which another
small quantity was taken in watch glass and a few drops of phloroglucinol and
concentrated hydrochloric acid were added, mounted in glycerine to locate lignified cells
and oberverved the characters under digital microscope. (Wallis, 1987; Johansen, 1940;

3. Physico-chemical analysis: If the water content is high the drug can easily be
deteriorated due to fungus, The ash content indicates the total amount of inorganic
material after complete incineration and the acid insoluble ash is an indicative of silicate
impurities might be due to improper washing of the drug. The alcohol and water soluble
extractive indicates the amount of bioactive chemical constituents in a given amount of

standardization of ASU herbal products such as moisture content of the powdered sample
at 105ºC, ash values, acid insoluble ash, solubility in water and alcohol, pH values and
bulk density and estimation of sugar etc., are useful tools were studies as per standard
methods (Anonymous,2021;2011;2009;2008;1986; Sagar et al., 2024a&b;2023 a &b;
2022a&b; Kumar et al., 2021).[1][2][8][9][10][13][26][27][32][33][36]
4. TLC/HPTLC finger printing analysis: The drug samples (2gm) were soaked in
chloroform and alcohol separately for 18 hours and refluxed for ten minutes on water bath
and filtered through What man N0.1 filter paper. The filtrates were concentrated and
made up to 10 ml in volumetric flask with respective solvents (Saxena and Yadav,
1983).[39] TLC/HPTLC finger print studies of chloroform and alcohol extracts of the drug
were carried out using 1307eculariz plate precoated with silica gel 60 F254 (E. Merck)
with CAMAG Linomat IV sample applicator. The chromatograms of both the extracts
were taken using the solvent systems toluene: ethyl acetate (8: 2 or 9 : 1) and toluene:
ethyl acetate (8 : 2 or 6 : 4) and Toluene: Ethyl acetate: Methanol (7:2:1) for chloroform
and alcohol extracts respectively. The plates were dried at room temperature and
observed the spots at various wavelengths. The plates were scanned at 254 nm and to
record the finger print spectrum after that same plates were visualized at UV-366 nm and
derivatized with spraying of vanillin-sulphuric acid reagent and heated at 105° C till
appeared coloured spots (Khan et al., 2022; Sagar et al., 2024a &b; 2023 a &b; 2022b;

RESULTS AND DISCUSSION
Macroscopic: The Flowers of Dhataki / Gul-e-Dhawa (Woodfordia fruticosa) is about 1.2
cm long and occurs as single or in bunches. The calyx is about 1.0-1.6 cm long, ridged and
glabrous, bright red when fresh, but on drying, it fades. Dried flower of Dhataki /Gul-eDhawa are yellowish brown in colour, innumerable, arranged in dense auxiliary paniculatecymose cluster, with short glandular pubescent pedicels. The calyx is long, striated, covered
with glandular dots. The petals are yellowish brown, papery, slightly longer than the calyxteeth, ellipsoid and membranous, usually splitting the calyx near the base, and are irregularly
dehiscent. A very minute sepal is attached outside the juncture of the calyx tooth and is
deeper in colour. The petals are 6 in number and are stuck inside the mouth of the calyx tube,
slightly longer than the calyx tooth. The filament is filiform, curved at the apex, keeping
anthers inside calyx-tube, and is almost rounded or ovate. The carpels are united in 2, ovary
superior, style filiform, long than ovary and stamens. (Sagar et al., 2024a&b; Giri et.al.,2023;
Anonymous.2021; 2011;2009; 2008).[1][2][4][10][27][32][33]
Microscopic identification: The transverse section of sepal shows a single-layered
cuticularized epidermis, provided with both glandular and covering trichomes. The epithelial
is multicellular, long and is consisting of a thin-walled stalk and a globose. The unicellular
thick-walled is broad at the base and pointed at the apex. The ground tissue consists of thinwalled parenchymatous cells provided with sparsely distributed covering trichomes. The

transverse section of filament shows an epidermis composed of single-layered tangentially
elongated cells and is covered with a very thick-cuticle ground tissue that consists of thinwalled parenchymatous cells with intercellular spaces and is surrounded by a vascular
cylinder of spirally thickened vessels. The transverse section of anther shows a single-layered
epidermis covered with a cuticle followed by several layers of thickened cells and is
surrounded by pollen-sacs having numerous pollen grains measuring approximately 12-16 µ.
The ovary is bicarpellary and laterally flattened and as such appears elongated in tranverse
section. The anther lobes are tetra-sporangiate and the walls separating the locules get
disorganized. A lobe shows an epidermis formed of large colourless cells followed by a
fibrous layer. (Sagar et al., 2024a&b; Giri et.al.,2023;Anonymous.2021; 2011;2009;
2008).[1][2][4][10][27][32][33]
Physicochemical standardization: The organoleptic evaluation of the whole plant of T E.
revealed that it was Light bright golden yellow, Characteristic taste, had a Indistinct odor and
Foreign Matter. (Table 1,entry 1- 4). The entire T E. flower part of plant organoleptic
characteristics was discovered to be the same as those mentioned in botanical literature.
Foreign substances including other plants, mould, insects, excrement, sand, stones, chemical
residues, etc. are prohibited in herbal medicines. In the present study, the foreign matter in
the whole plant of T E. was found to be Nil, which is within the permissible limits with
reference to the Ayurvedic Pharmacopoeia of India (Ali et al.,2016; Anonymous,1986;
2000;1991; 2007). The moisture content in any herbal drug is recommended to be up to 10%
(Sumbul et al., 2012), thus preventing spoilage. The Foreign matter, w/w and Loss of weight
on drying (LOD/ Moisture %, w/w at 105 °C in T E. Samples WFl-1, WFl-2 and WF-3 were
found to be Foreign matter, w/w- (0.08 %,0.07%,0.08%), LOD/ Moisture ,w/w(6.054%,6.010% 6.320%), The ash value is an important parameter for identifying
adulterants in an herb (Ali et al., 2016). The higher ash value shows the presence of inorganic
substances in the tested plant material (Husain et al., 2012). The total ash and acid-insoluble
ash % values of T E. were found to be Total ash, w/w- (5.79%,5.82%,6.93%), Acid insoluble ash, w/w-(0.776%,0.770%,0.778%), respectively. The extractive values % of ethanol,
and water were found to be Alcohol and Water soluble extractive matter, w/v(12.80%,12.46%, 12.38%) & (24.40%,24.46%, 24.50%) respectively. Such results indicate
that most of the phytoconstituents of T E. are soluble in ethanol and water. The pH of the test
material was found to be (4.8,4.9,4.8), (Table 1, entry 4–10) (Sangeeta et al., 2016). The
acidic nature of the test drug shows its good absorption through the mucous membrane of the

serious health issues in humans (Sangeeta et al., 2016 and Kancherla et al., 2023). The entire
T E. plant’s physicochemical constants were all with in acceptable limits according to the
Indian Ayurvedic Pharmacopoeia and Indian Unani Pharmacopoeia. (Sagar et al.,2024a&b;

9. Antimicrobial activity: The anti -microbial activity is an property of the substance to kill
or prevent the growth of the bacteria it significantly increases the shelf life of the product,
reduce the risk of contamination. It is an significant aspect for the quality and stability of
the product. The antimicrobial activity of the formulated WF. Samples was done by from
the applied appropriate Method, for the preparation of flowers extracts of W.F. the
flowers were first washed 2-3 times with tap water and then with sterilized distilled water.
100 gm. Flowers of (Woodfordia fruticosa (Linn) Kurz).were crushed in blender resulting
in the formation of a paste, which was mixed in 250 ml of absolute alcohol (Sagar et
al.,2006; Ghanaksha and Kaushik, 1999) [34]. Alcoholic extract so prepared was allowed
to evaporate at room temperature until 80 ml of it was left. This extract was squeezed
through double layer musline cloth and filtered through Whattman filter paper No-42 and
was centrifuged at 5000 r.p.m. for 20 minutes and then sterilized by passing through 0.2
micron disposable filter. Maller Hinton Agar (Hi media No. M173) media was used to
test antimicrobial activity against E. coli, S.aureus, S. typhi and K. pneumoniae by disc
diffusion method (Sagar et al.,2006; Ananthanarayana and Panikar, 1996) [34]. 5 mm
diameter discs are charged with appropriate concentration of the extract and standard
antibiotic oxytetracycline (one unit concentration), distilled water and absolute alcohol
served as control. In the applied investigated studies 100%,50%,25% Concentration of
Flowers Extracts and Anti-biotic drug Oxytetracyline 1 unit concentration as a standard
taken for Anti-bacterial potential research investigation of W F. The plates are then
incubated at the appropriate temperature at 370 °C for the growth of the test organisms,
for 24 hours. The antimicrobial activity was evaluated by measuring the diameter of
inhibition zone in mm. After incubation, the plates are examined for the zone of
inhibition, which are the clear areas around the well where the growth of microorganisms
has been inhibited by the test substance. The diameter of the zones are measured and is
used as an indicator of potency of the antimicrobial activity. Antimicrobial activity shown
to be Table- 4 respectively(Sagar et al., 2024a&b; Giri et al.,2023; Najda et al.,2021;

Phytochemistry & Bioactive phytochemical constituents
The Stem of Dhataki contains C-glycosidenorbergenin, yield gum, and betasitosterol.k. Its
leaves are rich in ursolic acid, betulinic acid, woodfruticosin, lawsone, Lupeol, betulin, betasitosterol. Woodfordia fruticosa flowers are rich in Woodfordins A- D, oenotherin A. The
phytochemicals present in the plant consist of both organic and inorganic chemicals, which
are secondary metabolites of the plant. These chemicals have various activities which
indirectly lead to the pharmacological response of the plant. woodfordins E-I and
isoschimawalin A. Therefore, W. fruticosa contains numerous chemicals in it, which are
phenolic, non-phenolic, flavonoids, essential oil, etc.,(Giri et.al.,2023).[4] which contain
compounds like 1,2,3,6-tetra-O-galloyl-β-d-glucose, 1,2,3,4,6-penta-O-galloyl-β-d-glucose,
tellimagrandin, gemin D, heterophylliin A, woodfordins A, B, C and oenothein B. In 1992
new constituents were introduced by (Yoshida et. al.,1992).[35] The flower of this plant
mostly contains flavonoids (kaempferol, quercetin) and a few non-phenolic compounds like
hecogenin (Khan et.al.,2019; Raghuwanshi et.al.,2019).[17][18] The plant contains various
tannins, flavonoids, alkaloids, glycosides, sterols and triterpenoids (Berhoft.2010).[29] From
the flower, some known and new hydrolyzable tannin constituent is isolated and the structure
of that group has been identified by (Yoshida et.al.1990),[35] and plant contained other
bioactive phytochemical constituents such as γ -Terpinene, Dihydrocarvyl acetate, 1Decalone
(cis-trans),
cis-7-Decen-1-al,
Tetradecanoic
acid,
Palmitic
anhydride,
Pentadecanoic acid, Octadecanoic acid, n-Hexadecanoic acid, and 3-Decyn-1-ol, 2,6Octadien-1-ol, 3,7-dimethyl-, acetate, €-(Geranyl acetate), as well as Caryophyllene Epoxide,
Cyclopropaneoctanoic acid, Cyclopropaneoctanoic acid, 2H1-Benzopyran-2-one, 2H-1Benzopyran-2-one, and gamma-elemene (Najda et.al.,2021).[11]
The leaves of the W. fruticosa were observed to have polyphenolic groups such as lawsone,
glucogallin, ellagic acid, gallic acid, quercetin 3-O-(6-β-galloyl)-β-d-galactopyranoside,
quercetin 3-O-α-L-arabinopyranoside, methyl
3-O-methylgallate,
myricetin 3-O-α-L
arabinopyranoside, etc and essential oil containing α-pinene, β-selinene, γ-curcumene,
germacrene-D, β-caryophyllene, etc (Joshi et. al.,2019; Kaur et. al.,2010;Dan et. al.,1984;
Saoji et.al.,1972).[16][31][37][41] while the leaves contain terpenoids such as isocarveol, geraniol,
citral, thymol, eugenol, geranyl acetate, linalool, thiogeraniol, lupeol, betulin, betulinic acid,

oleanolic acid and ursolic acid (Joshi et. al.,2019; Khan et.al.,2019; Raghuwanshi et.al.,2019;
Dubey et.al.,2014;Dan et. al., 1984).[16][17][18][21][37] The stem of this plant contains
compounds like β-sitosterol and octacosanol (Chauhan et.al.,1976).[40] Lot of research work
has been done and reported on W. fruticosa extracts, isolated phytochemicals are still
unexplored, which can have a potent role in drug development. Bioassay-guided isolation
may be used in the future to discover the key bioactive chemicals responsible for
pharmacological effects. Although W. fruticosa has a wide range of medicinal and traditional
applications, there is still a scarcity of information on the exact mechanisms underlying the
pharmacological
activities.
Therefore,
extensive
research
on
different
types
of
phytochemicals obtained from this plant is required to determine their exact target sites,
structure-activity relationships, pharmacological activities and mechanism of action for the
development of safe and effective herbal drugs for better management of different diseases
(Giri et.al.,2023).[4]
