【摘要】 <正> 紫金牛(Ardisia japonica(Hornsted)Blume)系紫金牛科草本植物,分布在我国长江流域、华南、西南等地,资源丰富。早在宋朝苏颂的“图经本草”中已有记载,谓其“气味辛平,无毒,主治时疾隔气,去风疾”;李时珍“本草纲目”谓其主治:“解毒破血”。近年来国内用紫金牛全草治疗肺结核、慢性支气管炎都有较好的效果。我们从紫金牛全草中分离得两个抗结核有效成份酚性化合物,紫余牛酚Ⅰ(Ardisinol Ⅰ)和紫金牛酚Ⅱ(Ardisinol Ⅱ)。前人曾报道从紫金牛更多还原

【Abstract】 Two amorphous resorcinols, named ardisinol I C₂₀H₃₂O₂ and ardisinol Ⅱ C₁₉H₃₀O₂ have been isolated from the whole plant of Ardisia japonica （Hornsted） Blume （Myrsinaceae）. Antitubercular tests in vitro show that both ardisinols from the plant are active principles against tubercle bacillus. Their chemical structures have been determined by spectrostypic analysis and chemical degradation respectively as 2-methyl-5 （S）-tridec-8-enyl -resorcinol and 5-（S）-tridec-8-enyl-resorcinol.更多还原
