从狭叶紫草的根中分离得到两个新的三萜皂苷，分别为Ardisicrenoside K(1)和Ardiicrenoside L(2)。其结构已确定为3β-O-{α-L-鼠李糖基]-(1->2)-β-D-吡喃葡萄糖基-(1->4)-[β-D-吡喃葡萄糖基-(1->2)]-α-L-阿拉伯吡喃糖基}-13β，28-环-16-氧-30，30-二甲氧基齐墩果烷和3-β-O-{β-D-吡喃葡萄糖基-(1->2)-β-D-吡喃葡萄糖-(1->4)-[β-D-吡喃葡萄糖基-(1-gt；2)]-α-L-阿拉伯吡喃糖基}-13β，28-环氧基-16α，20-二羟基齐墩果烷。对它们对植物病原真菌稻瘟病菌的体外抗真菌活性进行了评价。
Two new triterpenoid saponins, ardisicrenoside K (1) and ardisicrenoside L (2), have been isolated from the roots of Ardisia crenata Sims. Their structures have been determined as 3 beta-O-{alpha-L-rhamnopyranosy]-(1 -> 2)-beta-D-glucopyranosyl-(1 -> 4)-[beta-D-glucopyranosyl-(1 -> 2)]-alpha-L-arabinopyranosyl}-13 beta,28-epoxy-16-oxo-30, 30-dimethoxyoleanane and 3 beta-O-{beta-D-glucopyranosyl-(1 -> 2)-beta-D-glucopyranosyl-(1 -> 4)-[beta-D-glucopyranosyl- (1 -> 2)]-alpha-L-arabinopyranosyl}-13 beta,28-epoxy-16 alpha,20-dihydroxyoleanane by means of chemical evidences and spectral analysis. Their weak anti-fungal activity against the plant pathogenic fungus Pyricularia oryzae was evaluated in vitro.
