Investigation of the ethanolic extracts from Phytolacca rivinoides and P. bogotensis has resulted in the isolation of five new triterpenoid glycosides of serjanic acid. Their structures have been established mainly by spectroscopic methods (FAB-MS, 1H, 13C NMR, COSY, NOESY, TOCSY, HETCOR and J-resolved 1H NMR) as 3-O-(O-beta-D-galactopyranosyl-(1-->3)-O-beta-D-glucopyranosyl)serjan ic acid 28-O-beta-D-glucopyranosyl ester, 3-O-(O-beta-D-glucopyranosyl-(1-->3)-O-[beta-D-galactopyranosyl-(1-->4)] -O- beta-D-glucopyranosyl)serjanic acid 28-O-beta-D-glucopyranosyl ester, 3-O-(O-alpha-L-rhamnopyranosyl-(1-->2)-O-beta-D-glucopyranosyl-(1-->2)- O-beta-glucopyranosyl)serjanic acid 28-O-beta-D-glucopyranosyl ester, 3-O-(O-beta-D-glucopyranosyl-(1-->3)-O-beta-D-galactopyranosyl-(1-->4)- O-beta-D-glucopyranosyl)serjanic acid 28-O-beta-D-glucopyranosyl ester and 3-O-(O-beta-D-galactopyranosyl-(1-->4)-O-[beta-D-glucopyranosyl-(1-->3)] - O-beta-D-glucopyranosyl)serjanic acid.
对商陆（Phytolacca rivinoides）和波哥大商陆（P. bogotensis）乙醇提取物的研究已分离出5种新的瑟江酸三萜糖苷。它们的结构主要通过光谱方法（快原子轰击质谱、1H、13C核磁共振、化学位移相关谱、核欧沃豪斯效应谱、全相关谱、异核多量子相干谱和J-分解1H核磁共振）确定为3-O-（O-β-D-吡喃半乳糖基-（1→3）-O-β-D-吡喃葡萄糖基）瑟江酸28-O-β-D-吡喃葡萄糖基酯、3-O-（O-β-D-吡喃葡萄糖基-（1→3）-O-[β-D-吡喃半乳糖基-（1→4）]-O-β-D-吡喃葡萄糖基）瑟江酸28-O-β-D-吡喃葡萄糖基酯、3-O-（O-α-L-吡喃鼠李糖基-（1→2）-O-β-D-吡喃葡萄糖基-（1→2）-O-β-吡喃葡萄糖基）瑟江酸28-O-β-D-吡喃葡萄糖基酯、3-O-（O-β-D-吡喃葡萄糖基-（1→3）-O-β-D-吡喃半乳糖基-（1→4）-O-β-D-吡喃葡萄糖基）瑟江酸28-O-β-D-吡喃葡萄糖基酯和3-O-（O-β-D-吡喃半乳糖基-（1→4）-O-[β-D-吡喃葡萄糖基-（1→3）]-O-β-D-吡喃葡萄糖基）瑟江酸。
