ABSTRACT
An attempt for study of two terrestrial orchids i.e. Eulophia nuda (Lindl.) and Geodorum densiflorum (Lam.) Schltr. were carried out. Main focus was on the corms of both the orchids due to its huge medicinal properties like anticancerous, antioxidant, antidiabetic, antimicrobial, phytotoxic, etc. This is one of the prime reasons behind their threatened status along with endemic habitat. The parameters which were analysed during the study include macro- and micro-morphology, preliminary phytochemistry, and antioxidant activity (DPPH activity). In macro-morphology of both the orchids, slight difference was reported and, thus sometimes Geodorum densiflorum is being used as an adulterant in place of Eulophia nuda. During micro-morphological analysis, the oxalate crystals, raphides, mucilage ducts, starch grains, and oil granules were observed from cortical region of corm and in the mesophyll tissue of leaves in both the orchids. Stomatal Index of leaf surface was calculated along with the type of stomata, i.e. Cyclic II type. Preliminary analysis of phytochemical constituents in both the orchids was performed with three different solvent systems. A comparative antioxidant activity between leaves extract of both the orchids was carried out.
