The main molluscicidal activity of the methanol extract of Lysimachia sikokiana is due to several triterpenic saponins called sakuraso-saponins. The most active component was isolated from the aerial parts and elucidated as 3-O-beta-xylopyranosyl-(1----2)-beta-glucopyranosyl-(1----4)- [beta-glucopyranosyl-(1----2)]-alpha-arabinopyranosyl protoprimulagenin A, named lysikoianoside 1, on the basis of 1H- and 13C-nuclear magnetic resonance spectral data and methylation analysis results.
珍珠菜的甲醇提取物的主要杀螺活性归因于几种称为樱草皂苷的三萜皂苷。最具活性的成分是从地上部分分离出来的，根据氢核磁共振光谱数据和甲基化分析结果，鉴定为3-O-β-吡喃木糖基-(1→2)-β-吡喃葡萄糖基-(1→4)-[β-吡喃葡萄糖基-(1→2)]-α-阿拉伯吡喃糖基原报春皂苷元A，命名为珍珠菜皂苷1。
