Abstract:
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.
