ABSTRACT:Genus Curcuma is medicinally important. Among five Curcuma species grown in Sri Lanka, C. oligantha is unexplored. Therefore, current study was conducted to identify plant and establish chemical profile of the rhizome of C. oligantha essential oil. Mature whole plants of C. oligantha were collected in the flowering season in 2016 in Badulla district. Voucher specimens of the plants were authenticated & deposited at the National Herbarium, Peradeniya, Sri Lanka. Dried powdered samples were extracted by hydro-distillation with Clevenger’s apparatus (6 h). GC-MS analysis was carried out on a RTX WAX capillary column. Morphologically, leaf surface and red-brown short stem, pubescent corolla tube, labellum yellow centrally were observed. Microscopically, single layer palisade cells, diamond shaped prismatic crystals, anomocytic stomata, annular and reticulate xylem vessels, dumbbell shape starch grains were observed. Major chemical constituents found in rhizome were β-caryophyllene (15.07%), phytol (13.38%), and α-humulene (8.24%).
