ABSTRACT
stigmasterol; 9, 24methylenecholesterol; 10, stigmastanol; 11, sitosterol; 13, ∆7,22stig-mastanediol; 14, ∆7,22-methylene cholesterol; 16, ∆5-avenasterol; 17, ∆7stigmastenol; 21, ∆7-avenasterol; other peaks in this subfraction were not identified; (monomethylsterols): 25, campesterol; 27, obtusifoliol; 30, sitosterol; 33, methyl lophenol; 34, cycloeucalenol; 37, 24-methylene lophenol; 39, ethyl lophenol; 43, citrostadienol; other peaks in this subfraction were not identified; (dimethylsterols): 46, cycloartanol; 49, cycloartenol; 51, 24-methylene cycloartenol; other peaks in this subfraction were not identified. GLC conditions: Supelcowax 10 flexible quartz capillary column (15m× 0.32mm i.d.), installed in a HewlettPackard model 5880 gas chromatograph equipped with a flame ionization detector. The carrier gas was hydrogen with 2-5 psi head pressure. Column temperature was isothermal at 250°C, while the split injector temperature was 270°C. (From Ref. 57.)
