Diterpenoids from the fruits of Vitex trifolia.
An abietane-type diterpene, named vitetrifolin A, and two labdane-type diterpenes, named vitetrifolins B and C, were isolated from the acetone extract of the fruits of Vitex trifolia L. (Viticis Fructus; Verbenaceae) along with three known diterpenes, rotundifuran, dihydrosolidagenone and abietatriene 3beta-ol. The structures of these compounds were elucidated on the basis of spectroscopic analysis, X-ray crystallographic analysis and chemical evidence.
