A new diterpenoid and a new triterpenoid glucosyl ester from the leaves of Callicarpa japonica Thunb. var. luxurians Rehd.

摘要

A new abietane-type diterpenoid and a new oleanane-type triterpenoid glucosyl ester were isolated from the leaves of Callicarpa japonica Thunb. var. luxurians Rehd. (Verbenaceae) along with 11 known compounds, comprising seven triterpenoids, two sterols, a flavonoid, and an aliphatic glycoside. Their chemical structures were determined on the basis of spectroscopic data.
