Abstract Dioscorea alata L. (family Dioscoreaceae) is a popular food and nutritional supplement in various parts of the world. It is also used for the treatment of diverse ailments in Indian and Chinese ethnopharmacological practices. Recent pharmacognostic studies have demonstrated potent immunomodulatory activities of D. alata extracts. However, the basic phytochemical constituents remained mostly unknown. Therefore, the present study was performed to identify the major phytochemical constituents present in D. alata leaf and stem. The plant materials were initially derived to comparatively volatile and non-polar state using silylation method. The samples were then analysed using gas chromatography coupled with a single quadrupole mass spectrometer. Compound identification were performed by mass fragment comparison. The results revealed the presence of several bioactive constituents which could be attributed to the nutritional value and potent bioactivities of D. alata.Practical ApplicationsD. alata is a nutritious food and its consumption is associated with treatment of various diseases in traditional medicinal systems. The present study, reveals the identity of the bioactive phytochemicals present in the leaf and stem of D. alata. The individual bioactivities of the phytocompounds identified could be correlated with the pharmacological properties of D. alata.
