穗栎(Quercus Spicata Smith)系长在尼泊尔的约8米高的植物,其树皮当地用于治疗腹泻和痢疾,具有解热和降血糖的作用,从其树皮分得两个新三萜一穗栎素A和B(querspicatin A. B),通过化学和~1HNMR,~(13)CNMR 以及质谱检测,两者的结构分别为:3β-(3′,4′-二羟基肉桂酰氧基)-9α-羟基-7-氧代-羽扇豆-20(30)-烯和3β,9α-二羟基-7-氧代-羽扇豆-20(30)-烯。穆栎的干树皮粉末(3kg)在索氏提取器 Quercus Spicata Smith is a plant about 8 meters in length in Nepal. Its bark is used locally for the treatment of diarrhea and dysentery. It has antipyretic and hypoglycemic effects. It has two new trifoliates from its bark. One bursin A and B (querspicatin A. B) were detected by chemical and 1H NMR, 13C NMR and mass spectrometry. Their structures were: 3β-(3′,4′-dihydroxycinnamoyloxy) Base)-9α-hydroxy-7-oxo-Lupin-20 (30)-ene and 3β,9α-dihydroxy-7-oxo-Lupin-20 (30)-ene. Musk’s dry bark powder (3kg) in Soxhlet extractor
