Studies of the CHCI3 extract of E.japonica resulted in the isolation of a new derivative 3p, 6a, 19a trihydroxy-urs-12-en-28-oic acid, 5, besides the already reported maslinic acid 6, 2a-hydroxy-ursolic acid 7, 2a, 3a, 19a-trihydroxy-urs-12-en-28 oic acid or tormentic acid 8, 2a, 3p,19a, 23-tetrahydroxy-urs-12-en-28-oic acid 9 and ursolic acid 10 ( Fig.l). [Pg.118]

Thus polyhydroxylated triterpenes from E. japonica are very active as hypoglycemic agents. Noreen and Villar (38,39) proposed that the crude alcoholic extract of E. japonica and tormentic acid act by stimulating Langerhan s p cells which results in an increased insulin release because the crude extract and tormentic acid are inactive in alloxan-treated animals. The action mechanism of S and 7 seems to be analogous. Studies are in progress to delineate this mechanism more precisely. [Pg.139]
