“…Thus, in recent years there has been a rapid increase in the standardization of medicinal plants. Though modern techniques are available, but still identification of medicinal plants is more reliable on pharmacognostic studies [24]. In this regard, the macroscopic and microscopic features of root have been studied.…”

Context: Ethnomedicinally, the root of Wedelia trilobata L. (Asteraceae) has long been used in various ailments in traditional system; most importantly it is used against backache, muscle cramp, rheumatism, stubborn wounds, sores, swelling and arthritic pain, fever and malaria. The main problem experienced in the standardization of herbal drugs is lack of proper identification of plant source. So there is need to establish quality control parameters by using pharmacognostic and phytochemical evaluation, which ensures the purity, safety and efficacy of medicinal plant W. trilobata. Aim: To evaluate pharmacognostic properties including macroscopic, microscopic and physicochemical parameters of the root of W. trilobata. Methods: Micro and Macroscopic characters of fresh and dried root samples were investigated. Physicochemical parameters were done by utilizing WHO recommended parameters, preliminary phytochemical and fluorescent analysis of root sample were performed for identification and standardization of root of W. trilobata. Results: The color, shape, size, odor and surface characteristics were noted from the root and powdered root material of W. trilobata. Light electron microscope images of cross section of root and powdered root revealed that the presence of cork cells, lignified spiral vessels, and parenchymatous cells. Phytochemical screening showed the presence of flavonoids, tannins, phenols, saponins, steroids, carbohydrates and glycosides. Physicochemical parameters such as moisture content, ash value, extractive value and fluorescent behavior of root powder were determined. These parameters are useful tools to differentiate the powdered drug material. Conclusion: The present study is helpful to supplement the information with regard to its standardization and identification and in carrying out further research in Ayurvedic system of medicine.

Objective: To evaluate the pharmacognostic characters of Madhuca indica J.F. Gmel leaf and stem an important traditional medicinal plant. Method: In the present investigation, pharmacognostic parameters like macroscopic and microscopic and powder characters of leaf and stem were studied. Preliminary phytochemical and physiochemical analyses were done by using reported methods. Fluorescent behavior of the leaf and stem powder were also tested. Results: The macroscopic study showed that the leaf was simple and ovate with sinuate margin, acuminate at apex, decurrent at base and surface glabrous and venation was pinnate. The microscopic study of leaf revealed the presence of dorsiventral type of cellular arrangement, unicellular trichomes, prismatic crystals and anomocytic stomata; while the microscopic study of stem revealed the presence of vascular bundles in zig zag form, large central collenchymatous pith. Pith cells were polygonal in shape with minor angular thickenings. Physiochemical analysis of leaf showed total ash, water soluble ash and acid insoluble ash as 4.6, 0.83 and 0.5 %w/w respectively while in stem it was 5.37, 1.5 and 1.0 %w/w respectively. In both parts maximum extractive value was in methanol. Phytochemical analysis revealed maximum amount of flavonoids in leaf and tannins in stem. Conclusions: Various pharmacognostical characters observed in this study will help in identification and standardization of M. indica; will also help in quality control and formulation development.

“…There are many reports in the literature where pharmacognostic study of leaves of different plants is reported eg. Melaleuca leucadendron [27] , Nelumbo nucifera, [28] Manilkara zapota, [29] Eucalyptus globulus, [30] Cinnamomum verum, [31] Terminalia catappa, [32] Psidium guajava [33] and Polyalthia longifolia. [34] In conclusion, these parameters are reported for the first time for P. pinnata leaf.…”
