Diterpenoids and phenylethanoid glycosides from the roots of Clerodendrum bungei and their inhibitory effects against angiotensin converting enzyme and α-glucosidase

Four diterpenoids (1-4) and two phenylethanoid glycosides were isolated from Clerodendrum bungei roots. Some of the isolated compounds showed angiotensin converting enzyme or α-glucosidase inhibitory effects.114
