RESUMO

A new steroidal ester, beta-rosaterol palmitate (1) along with ten known compounds, uvaol(2), 3-epi-ursolic acid (3), 2alpha, 3beta, 24-trihydroxyolean-12-en-28-oic acid (4), 2alpha, 3alpha, 24-trihydroxyurs-12-en-28-oic acid (5), 2alpha, 3alpha, 24-trihydroxyolean-12-en-28-oic acid (6), 2alpha, 3alpha, 24-trihydroxyolean-12-en-28-oic acid-28-O-beta-D-glucopyranosyl ester (7), (Z)-9-hexadecenoic acid (8), octacosyl alcohol (9), beta-sitosterol (10) and beta-daucosterol (11), has been isolated from the stems and leaves of Vitex trifolia.
