Vitexin

Ficus deltoidea or Mas cotek is one of the most popular plant herbs that have been widely used traditionally as postpartum treatment and health tonic. Preliminary or existing extraction method has been used to extract the plant herbs that have low productivity range. This method however can still produce the desired products, but the work can be laborious and not efficient in large scale processing. Besides, the sample preparation has no evidence in advances because obtaining such extraction products at sufficient concentrations usually involves extraction with large amounts of organic solvents and toxic, followed by evaporation. Production of Vitexin from Ficus deltoidea extraction under various sonication regiments is reported. Batch extractions were carried at low intensity sonication (8.66 W cm-2 sonication intensity at the sonotrode tip) using 10%, 20% and 40% duty cycles. (A duty cycle of 10%, for example, was equivalent to sonication for 1 s followed by a rest period (no sonication) of 10 s.) The extracts were compared with those obtained by conventional boiling extraction, in terms of bioactive constituents yield and chemical composition. In the aqueous (conventional) extracts, the actual percentage weight of Vitexin varied in the range 0.122 ± 0.013 ~ 0.386 ± 0.018 (%w/w) compared to sonicated extracts with 2-fold increases at a range of 0.127 ± 0.001 ~ 0.738 ± 0.050 (%w/w) after 8 hours of extraction with sample-to-water ratio of 10:1 (g/ml) at 50, 70 and 100°C. Both ultrasonic-assisted and aqueous extracts were characterized and standardized by HPLC-diode array detector using a pharmacologically active marker, Vitexin. The experimental values under optimal conditions were in good consistent with the predicted values, which suggested that ultrasonic-assisted extraction (UAE) is more efficient process as compared to conventional boiling extraction (AE). It recommends that ultrasound extraction of F. deltoidea leaves is substantially feasible to replace the traditional time-consuming and low efficiency preparation procedure in the future modernized and commercialized manufacture of this highly valuable herbal medicine.

Developing a new agent in the anti-inflammatory and analgesic field, plants secondary metabolites can be a good
source for the Non-Steroidal Anti-inflammatory Drugs (NSAID) drug development. For this purpose we
subjected the active compounds of Mimosa pudica Linn. to reveal its potentiality by molecular docking analysis
to find out its potent compound against COX which was done by GOLD docking analysis. Docking studies by
GOLD showed that vitexin of Mimosa pudica had the highest fitness score against the COX-1 which is 60.43 and
63.49 for COX-2 enzyme. Vitexin of Mimosa pudica detected with significant fitness score and hydrogen
bonding against COX-1 and COX-2 which may be a potent analgesic compound.

Vitexin is an apigenin flavone glycoside isolated from natural sources. It is considered as important as other flavonoids such as quercetin, rutin, kaempferol. In this review, we have documented some major occurrence and its major pharmacological activities such as anti-inflammatory, anti-oxidant, cardioprotective, anti-cancer, antinociceptive, anti-convulsant, memory enhancing potential and anti-diabetic activities. We have also drawn its 3D structure,total charge density by huckel using ChemDraw 3D and its theoretical chemical properties and analysis by ChemDraw.

Mas Cotek or Ficus deltoidea var. deltoidea leaves extracts contain various beneficial properties such as antidiabetic, antihypoglycemic and antioxidant activities, which can be enzymatically extracted in water. Vitexin is one of the antioxidants and remarkable compound of flavone C-glycosides found in Mas Cotek leaves. Cellulase is one of the essential enzymes applied to hydrolyze cellulose into fermentable sugars and therefore, this enzyme was used to extract vitexin in this study. Single parameter approach was used to determine factors influencing the enzymatic-mediated extraction. These factors were enzyme concentration, sample-to-water ratio, temperature, incubation time and agitation. The maximum yield of vitexin found was 0.547% under the optimum conditions: sample-to-water ratio 1:10 g/mL, enzyme concentration 0.4%, incubation time of 240 min, temperature of 50 ± 0.02°C and stirring speed of 200 rpm. The highest amount of reducing sugar obtained was 4.039 mg/mL with the use of 0.4% cellulose. A correlation was also observed between the yield of vitexin and reducing sugars.
