According to World Health Organization (WHO), in developing countries more than 3.5 billion people relay on herbal drugs for their primary health care. In the present study, an attempt was carried out to authenticate some selected medicinal plants (Fagonia cretica L., Peganum harmala L., Tribulus terrestris L., Chrozophora tinctoria L. Raf. and Ricinus communis L.) from family Zygophyllaceae and Euphorbiaceae using light and scanning electron macroscopic techniques. Macroscopic evaluation and comparative anatomy (Light Microscopy) of the root and fruits revealed great diversity in macro and microscopic features. Scanning electron microscopy (SEM) of root powder showed non‐glandular trichomes, stellate trichomes, parenchyma cells and vessels. Fruits SEM exhibited non‐glandular trichomes, glandular trichomes, stellate trichomes, peltate trichomes and mesocarp cells. Both macroscopic and microscopic evaluation plays a crucial role in the correct substantiation and validation of novel sources. These findings can serve as an essential source of information to accomplish the authenticity and to appraise the quality and purity of the herbal drugs in accordance to WHO guidelines. These parameters can be used to distinguish the selected plants from their commonly used adulterants.Research Highlights In the current work, five plants (Fagonia cretica L., Peganum harmala L., Tribulus terrestris L., Chrozophora tinctoria L. Raf. and Ricinus communis L.) from Zygophyllaceae and Euphorbiaceae were investigated for macroscopy and microscopy (LM & SEM) for the first time. Macroscopic and microscopic evaluation disclosed great diversity in morphology and histology. Microscopy is the backbone of standardization process. Current study helped in correct identification and quality assurance of the plant materials. Their statistical investigation may possess great potency for plant taxonomists to further appraise the vegetative growth and tissue development which is requisite especially for fruit to enhance the yield of herbal drugs and their formulation. Further molecular studies, compounds isolation and characterization are required to deepen the knowledge of these herbal drugs.

P. roxburghii 나무가 띠엄띠엄 나있고 왜소한 Olea ferruginea가 있는 것을 보면 이곳의 원래 식생은 이들 두 가지 식물로 대표된다. 잘 가꾸고 보호한다면 본 연구의 조사지가 나무숲을 이루게되고 동식물 보호지로 조성되어 자원화할 수 있으리라고 생각한다.

Laboratory study was performed to investigate the allelopathic potential of its leaves, stem, litter, mulch, rhizosphere soil and rhizosphere soil extract. The experiment was conducted in a completely randomized design (CRD) by taking five replication per treatment. The results showed that aqueous extracts invariably reduced the seed germination, plumule \ radical growth, fresh\ dry weight of test species Triticum aestivum and Brassica compestris. Phytotoxicity of the plant was concentration and soaking duration dependent. Extracts of longer duration (48 hours) were inhibitorier. Leaves proved more toxic than stems. Hot water extract were inhibitory than aqueous extract obtained at room temperature .Added litter and mulching experiment also proved inhibitory. However rhizosphere soil and rhizosphere soil extract exhibited stimulatory to test species. Results of present studies showed that use of plant extract as herbicides to control the weeds will bring a great success in this area. Moreover, these positive allelopathic extracts should also be investigated to exploit its benefits in crop productions

D. innoxia reduced the ht. and dry wt. of all test spp. in mixed cultures. The 2 grasses also inhibited the growth of D. innoxia in mixtures. Aqueous extracts from D. innoxia had the same inhibitory effect. Seed germination of P. americanum was inhibited by D. innoxia leachates but that of S. italica was not. In field trials, volatiles from intact shoots of D. innoxia inhibited germination of P. americanum and S. italica but not of Trifolium resupinatum. Radicle growth of all 3 spp. was inhibited by the volatiles. In laboratory tests, volatiles from detached shoots of D. innoxia inhibited germination of P. americanum only but inhibited radicle growth of Brassica campestris, S. italica and P. americanum. Germination in D. innoxia soil beds was inhibited in B. campestris only, but radicle growth was inhibited in B. campestris and S. italica.ADDITIONAL ABSTRACT:Relatively bare areas are frequently present under and around Datura innoxia Mill thickets, although several herbaceous species may grow well under other adjacent plants causing a shade equal to that of Datura. Field and laboratory experiments revealed that Datura significantly inhibited germination and growth of test species by root exudates, aqueous extracts from various parts, leachates and substances volatilizing from its shoot. Soil collected under and around Datura was inhibitory against the test species. The phytotoxicity depended upon the part assayed, its age, test species used and the physiological process involved. The presence of relatively bare areas under and around D. innoxia was due primarily to allelopathy
