A new triterpenoid saponin named esculentoside U(1), along with the five known compounds, was isolated and characterized from the roots of Phytolacca acinosa, a commonly used traditional Chinese medicine with anti-inflammatory and anti-rheumatoid activities. The structure of the new saponin was elucidated as 3-O-[β-D-glucopyranosyl-(1→4)]-β-D-xylopyranosyl]-2, 23-dihydroxyolean-11, 13(18)-diene-28, 29-dioic acid 29-methyl ester(1). The assignment of all NMR signals of 1 was performed by means of 2D-NMR experiments.
从商陆（一种具有抗炎和抗风湿活性的常用传统中药）的根中分离并鉴定出一种名为商陆皂苷U(1)的新三萜皂苷以及五种已知化合物。新皂苷的结构被阐明为3-O-[β-D-吡喃葡萄糖基-(1→4)]-β-D-吡喃木糖基]-2, 23-二羟基齐墩果-11, 13(18)-二烯-28, 29-二酸29-甲酯(1)。通过二维核磁共振实验对1的所有核磁共振信号进行了归属。
