摘要：
The structure of a new 4α-methylsterol isolated from the immature seeds of Phaseolus vulgaris and the aerial parts of Gynostemma pentaphyllum has been shown to be 4α,14α-dimethyl-5α-ergosta-7,9(11),24(28)-trien-3β-ol by spectroscopic methods and by chemical correlation with obtusifoliol. This appears to be the first report of the isolation of a 4α-methylsterol with a Δ7,9(11)-diene system from nature. Abundances and chromatographic data of all identified 4α-methylsterols isolated from G. pentaphyllum are also given. © 1990.
