商陆皂苷A(1)是从商陆(Phytolacca Acinosa Roxb)根的75%乙醇提取物中分离得到的一个新的三萜皂苷。经波谱分析和理化性质鉴定为：3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-11-methoxy-jaligonic酸30-甲酯28-O-d-吡喃葡萄糖苷(1)，3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-jaligonic酸30-甲酯28-O-d-吡喃葡萄糖苷(2)。3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-jaligonic酸30-甲酯(3，植酸苷E)，3-O-d-木吡喃糖基-茉莉酸30-甲酯(4，植酸苷B)，下胡萝卜素(5)，棕榈酸单甘酯(6)，-谷甾醇(7)，胡萝卜苷(8)。
Phytolacacinoside A (1), a novel triterpenoid saponin, together with the seven known compounds, was isolated from 75% ethanol extract of the root of Phytolacca acinosa Roxb (Phytolaccaceae). Their structures were elucidated on the basis of analysis of spectroscopic data and physicochemical properties as 3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-11-methoxy-jaligonic acid 30-methyl ester 28-O--d-glucopyranoside (1), 3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-jaligonic acid 30-methyl ester 28-O--d-glucopyranoside (2, esculentoside G), 3-O--[(-d-glucopyranosyl-(14)-O--d-xylopyranosyl)]-jaligonic acid 30-methyl ester (3, phytolaccoside E), 3-O--d-xylopyranosyl-jaligonic acid 30-methyl ester (4, phytolaccoside B), hypaphorine (5), palmitic acid monoglyceride (6), -sitosterol (7), and daucosterol (8).
