Chyuri (Diploknema butyracea (Roxburgh) H. J. Lam) is widely used in Nepal for its medicinal properties and as a source of Chyuri ghee (fat) extracted from the seeds. The main purpose of the present study was the GC-MS analysis of fatty acids in seed fat of Chyuri after acidic methanolysis. Palmitic acid methyl ester (1), linoleic acid methyl ester (2), oleic acid methyl ester (3) and steric acid methyl ester (4) were identified as the main components. Ethnomedicinal use and distribution of Chyuri in Nepal is also discussed.

Key words: Chyuri, Diploknema butyracea, GC-MS, Nepal.
