PHYTOPHARMACOGNOSTICAL STUDY OF TUBERS OF EULOPHIA NUDA LINDL.Abstract
Plants and plants-based medicines have been used to treat many ailments since the ancient times. Family Orchidaceae to which orchids belongs is the largest family among monocotyledons. The genus Eulophia comprises perennial terrestrial orchids with fleshy tubers, rarely pseudobulbs. One such perennial herb having underground tubers, Eulophia nuda, belonging to family Orchidaceae, has been traditionally used for the treatment of tumours, scrofulous glands of the neck, bronchitis, skin rash and rheumatoid arthritis. In the present study the pharmacognostical and phytochemical evaluation of tubers of E. nuda was performed as it is helpful for the standardization and authentication of medicinal plant. The microscopical study showed the presence of xylem vessels, fibres, starch, raphides and acicular crystals. The phytochemical analysis of the tubers of E. nuda indicated the presence of carbohydrates, alkaloids, flavonoids, steroids, triterpenoids, etc. The results of the HPTLC fingerprinting confirmed the presence of the flavonoids like rutin, quercetin and kaempferol in the tubers of E. nuda.
