Abstract:Six compounds including two new triterpenes were isolated from the root of Actinidia eriantha Benth. Dy spectral analysis (IR, MS, 1H NMR, 13C NMR) and preparation of derivative the structure of the new triterpencs were elucidated as 24-acetyloxy-2α, 3α -dihydroxyurs-12-cb-28-oic acid and 2β, 3β, 23-trihydroxyurs-12-en-28-oic acid named eriantic acid A and eriantic acid B respectively. The known compounds were identified as β-sitosterol, daucousterol, urrsolic acid and 2α, 3α, 24--trihydroxyurs-12-en-28-oic acid.
