詳細
Five kinds of new diterpenes have been isolated from Isodon trichocarpus Kudo and Isodon japonicus Hara. The structures of isodocarpin and nodosin have been established as shown in the formulas (II) and (III). The spectral features of trichodonin, trichokaurin and oridonin are discussed, and the structures (IV) and (V) are tentatively proposed for trichodonin and trichokaurin, respectively.
