! Two new nortriterpenoids, pfaffine A and B (1-2), were isolated from the roots of Pfaffia paniculata Kuntze, along with ten known compounds including four ecdysteroids, ecdysone (3), 20-hydroxyecdysone (4), pterosterone (5), rapisterone (6), five triter-penoids, pfaffic acid (7), pfameric acid (8), mesembryanthemoidigenic acid (9), calenduloside E 6'-methyl ester (10), oleanolic acid 28-O-beta-D-glucopyranoside (11), and one monoterpene glycoside (+)-angelicoidenol-2-O--D-glucopyranoside (12). The structures of the new compounds were elucidated as 3 beta, 16 beta-dihydroxy-30-norolean-12,20(29)-dien-28-oic acid (1), and 3 beta-hydroxy30- norolean-12,20(29)-dien-28-oic acid-28-O-beta-D-glucoside (2) through the extensive analysis of 1D-((1)H, (13)C, DEPT) and 2D -NMR (COSY, HSQC, HMBC, NOESY) spectra, as well as by a chemical method.
