Structures of Scutellones D and E Determined from X-Ray Diffraction, Spectral and Chemical Evidence. Neoclerodane-Type Diterpenoids from Scutellaria rivularis WALL.

Abstract

A new neoclerodane-type diterpenoid lactone, scutellone E, together with a known compound, scutellone D (scuterivulactone D), has been isolated from aerial parts of Scutellaria rivularis WALL. Their structures have been determined from X-ray diffraction, spectral and chemical evidence.
