Four new neoclerodane-type diterpenoids, scutellones B, G, H, and I, from aerial parts of Scutellaria rivularis.

Abstract

Four new neoclerodane-type diterpenoids, scutellones, B, G, H, and I, have been isolated from aerial parts of Scutellaria rivularis WALL., and their structures elucidated on the basis of spectral and chemical evidence.
