Abstract

A binaphthoquinone; diphthiocol, two naphthoquinones; lawsone and 2-methoxy -1,4-naphthoquinone, and a sterol; spinasterol, were isolated from the root cultures of Impatiens balsamina . Their structures were established on the basis of UV, IR, mass, 1H NMR and 13C NMR spectral data. Diphthiocol is a new natural product in which its synthesis has been reported.
