本文报道从云南产金丝矮陀陀植物(Pachysandra axillaris)中得到的三个新甾体生物碱。它们的结构确定为:富贵草碱 G(20α-二甲胺基-3β-惕各酰胺基-5α孕甾烷),富贵草碱H(20α-二甲胺基-3α-苯甲酰甲胺-5α-孕甾烷),矮陀陀酯碱 A(20α-二甲胺基-3β-甲胺基-4β-苯甲酰氧基-5α-孕甾烷)。此外还得到已知的富贵草碱 A、B。
This article reports three new steroidal alkaloids from the Pachysandra axillaris plant in Yunnan. Their structures were determined to be: Argyrosin G (20α-dimethylamino-3β-indole amide-5α-pregnane), Argalin H (20α-dimethylamino-3α-phenacylamine) -5[alpha]-pregnane), sinoatrabase A (20[alpha]-dimethylamino-3[beta]-methylamino-4[beta]-benzoyloxy-5[alpha]-pregnane). In addition, the known rich grass alkali A and B were also obtained.
