Abstract

Aim: Hanshia dabar or hatkhan is one of the folklore plants of Odisha, which has been identified as Leea macrophylla Roxb. ex Hornem. of the family Vitaceae. Traditionally, its leaves are claimed to be used in the treatment of cancer. Pharmacognostical evaluation of various parts of the plants has not been reported. The present study has been designed to carry out detailed macro- and microscopic, physiochemical, and phytochemical aspects of leaves of L. macrophylla. Materials and methods: The fresh leaves, collected from Gandhamardan hills, Odisha, during the month of September 2016 were examined for its pharmacognostical characters and physicochemical, qualitative analysis, and HPTLC studies were done following the standard protocols recommended by the Ayurvedic Pharmacopoeia of India. Results: Leaves are compound, unipinnate, leaflets two pairs, and one terminal with short petiolule. Transverse section of rachis resembles the anatomy of stem and that of petiolule is somewhat deeply lobed heart shaped, section passing through midrib resembles inverted bell shape with two wings, one anterior and other posterior both ending with tapering ends. Leaf powder is greenish in color and microscopy reveals the presence of paracytic stomata. The plant is identified as L. macrophylla based on sequence homology and phylogenic analysis. Loss on drying is 7.39 ± 1.26, and qualitative results show the presence of alkaloids, flavonoids, and tannins, and HPTLC profile shows 6, 6, and 5 spots at short UV, long UV, and visible light, respectively. Conclusion: Leea macrophylla is a shrub with unipinnate compound leaves, and the leaflets possess 5-7 nerves arising from petiolule. Microscopic typical features of leaves belonging to genus Leea are the presence of raphides sacs, secretory cells, acicular crystals, and warty trichomes. The results obtained from the phytochemical study will be helpful in the determination of strength of purity and also for further standardization of the plant.
