摘要：
Three mixtures of steroids (1a+1b, 2a+2b and 3a+3b) and two flavonoid glycosides ( 4 and 5) were isolated from the ethanol extract of branches of Porcelia macrocarpa ( Warm.) R. E. Fries (Annonaceae). The steroids Stigmasta-4,25-dien-3-one (2a) and (22E)-Stigmasta-4,22,25-trien-3-one (2b) are news. The structures were elucidated by NMR and MS data and comparison with literature data of model compounds.
