前已报道云南产甘西鼠尾草褐毛变种(Salvia Przewalskii Maxim. var. mandarinorum Stib.,俗名紫丹参)中的紫丹参甲素和乙素。今应用HPLC方法,从工厂生产丹参酮H-A的下脚料中分离出一种新二萜邻醌的微量成分,取名为紫丹参丙素(przewaquinone C),橙红色棱柱状结晶(甲醇重结晶),C_(18)H_(16)O_4,熔点204～206C。紫外光谱λ_(ma(?))~(me(?))nm(log ε),222(4.10),250(4.04),269(4.15),346
Previously, purple salvia miltiorrhizae and B were found in S. lantus var. mansoni (Salvia Przewalskii Maxim. var. mandarinorum Stib., commonly known as purple salvia miltiorrhiza). This application of HPLC method, from the factory production of tanshinone HA scrap left out of a new two-o-quinoline micro-components, named puranwaquinone C (przewaquinone C), orange-red prismatic crystals (methanol recrystallization), C_(18)H_(16)O_4, melting point 204 ~ 206C. UV spectrum λ_(ma(?))~(me(?))nm(log ε), 222(4.10), 250(4.04), 269(4.15), 346
