OBJECTIVE To analyze the chemical constituents of Heterosmilax japonica Kunth. METHODS The sample was separated and analyzed by GC-MS. RESULTS 62 ingredients were elucidated. The major components were steroids and fatty acids. CONCLUSIONS The method is reliable, and the result provides a reference for further study of Heterosmilax japonica Kunth.

D012855 Sitosterols A family of sterols commonly found in plants and plant oils. Alpha-, beta-, and gamma-isomers have been characterized.
D013256 Steroids A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed) Steroid,Catatoxic Steroids,Steroids, Catatoxic
D019787 Linoleic Acid A doubly unsaturated fatty acid, occurring widely in plant glycosides. It is an essential fatty acid in mammalian nutrition and is used in the biosynthesis of prostaglandins and cell membranes.
