摘要：

Thirty-eight compounds were isolated from the roots and stem bark of Piptostigma fugax, besides three fractions of mixtures of homologues of two 6'-acylated sterol glucosides and fatty acids, respectively. Structures were determined by spectroscopic and chemical methods. Mixtures of homologues were analysed by GC-mass spectrometry after derivatization. 5 alpha-Cycloart-24-ene-3 beta,16 beta,21-triol, 4-hydroxy-4,7-dimethyl-1-tetralone and three onychine-type alkaloids (2,7-dihydroxyonychine, 7-hydroxy-2-methoxyonychine and 7-hydroxy-2,8-dimethoxyonychine) represent new compounds. N-Methylheteropsine has been isolated as a natural product for the first time.
