Stemodia serrata Benth., an aromatic weed on the verge of extinction, is analysed for its volatile oils and phenolics. The plant yielded 1.15% of a light greenish yellow volatile oil consisting of β- caryophyllene (32 %), endo-fenchol(29.8%) and p-mentha-1-(7)-8-diene (20.8%) as major components. The phenolics identified were a flavone scutellarein and phenolic acids like ferulic, o-coumaric, vanillic, p-OH benzoic and protocatechuic acids. All these compounds are found to be of great therapeutic potential and therefore large scale cultivation to preserve and utilize this species is recommended.
