chemical methods. Mixtures of homologues were analysed by GC-mass spectrometry after derivatization. 5α-Cycloart-24-ene-3β,16β,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.
摘要 从黑木耳根和茎皮中分离得到38 种化合物,另外还分离得到3 种6'-酰化甾醇糖苷和脂肪酸的同源物混合物。通过光谱和化学方法确定结构。衍生化后通过GC-质谱法分析同系物的混合物。5α-Cycloart-24-ene-3β,16β,21-triol、4-羟基-4,7-二甲基-1-四氢萘酮和三种甲酸类生物碱(2,7-二羟基甲氧基、7-羟基-2-甲氧基甲氧基和7-羟基-2,8-二甲氧基甲氧嘧啶)代表新化合物。N-Methylheteropsine 首次作为天然产物被分离出来。
