title: Four new halimane-type diterpenes, vitetrifolins D-G, from the fruit of Vitex trifolia.
abstract: Four new halimane-type (rearranged labdane-type) diterpenes, vitetrifolins D-G were isolated from the fruit of Vitex trifolia L. (Verbenaceae). Their chemical structures were determined on the basis of spectroscopic data as well as chemical evidence.
