isolated from the hexane extract of the root nodules of the Ayurvedic drug. (Roxb.) Moldenke. (Verbenaceae) has been shown to be a novel diterpenoid quinonemethide incorporating a δ-lactone moiety (3) and possessing (S) configuration at the chiral carbon atom from a consideration of its mass spectrum, UV, IR, 1H NMR and 13C NMR spectra, 2D NMR INADEQUATE and CD spectrum. (3) appears to be derived biogenetically
从阿育吠陀药物根瘤的己烷提取物中分离出的Bharangin。(Roxb。)摩尔登克。从其质谱,UV,IR,1 H NMR和13 C的角度考虑,(马鞭草科)已被证明是一种新颖的二萜类醌甲基化物,其结合了δ-内酯部分(3)并在手性碳原子上具有(S)构型NMR光谱,2D NMR不饱和光谱和CD光谱。(3)似乎是从假设的双萜骨架(pygmane(4))遗传产生的。
