Abstract

Two C-3/C-3"-biflavanones, chamaejasmine (1) and isochamaejasmin (2), were isolated from the roots of Stellera chamaejasme L. (Thymelaeaceae) and their stereostructures were elucidated on the basis of spectral and chemical evidence. Chamaejasmine was found to be a mixture of (-) and (+) forms (68 : 32) by high-performance liquid chromatographic analysis with a column for optical resolution.
