Comparative account of Leaf studies between E. alba (L.) Hassk. & W. trilobata (L.) A.S. Hitchc

Abstract The diversity of medicinal plants has been observed and used for medicinal and therapeutic efficacy from time to time. These plants having potential to produce wide forms of chemical constituents and secondary phytochemicals which imparts medicinal values to the plants. The current paper deals with comparative studies of leaf of E. alba and W. trilobata because now a days W. trilobata is known and used as Bhringaraja instead of an original plant E. alba, therefore the main aim of comparative study of leaves of E. alba and W. trilobata is to avoid adulteration for this purpose the number of modern technique have been used for standardization of these two medicinal plants includes pharmacognostic study. In the present research work, important phytochemical constituents were extracted from the methanol, water and chloroform respectively by using standard procedures. Histological study dealing with transverse section of leaf, qualitative microscopy includes vein-islets, palisade ratio, no. of stomata, type of stomata, stomatal index study and physicochemical characters such as analysis of total ash values, acid insoluble and water soluble values were determined, while on the other hand various extractive values also determined. Histochemical tests for alkaloids, flavonoids, saponins, tannins, steroids, glycosides, terpenoids, starch etc. were conducted for both the plants leaf sample and results are summarized in current paper.
