Abstract:Eleven triterpenoids were isolated from the leaves of Turpinia arguta (Lindl.) Seem. On the basis of spectral data, they were identified as ursolic acid (1), uncargenin C (2), 3β,6β,23-trihydroxyurs-12-en-28-oic acid (3), 3β,6β,19α,23-tetrahydroxyurs-12-en-28-oic acid (4), 1α,3β,23-trihydroxy-12-oleanen-28-oic acid (5), rosamultin (6), arjunglucoside II (7), 3β-O-β-D-glucopyranoylcincholic acid (8), cinchonaglycoside C (9),mussaendoside S (10),and 3β-O-β-D-glucopyranosyl quinovic acid 28-O-β-D-glucopyranosyl ester (11). All these compounds were obtained from T. arguta for the first time except compounds 1 and 6.
