Sesquiterpene components from the flower buds ofMagnolia fargesii.
From the Chinese crude drugshin-i, the flower buds ofMagnolia fargesii, four sesquiterpene, oplopanone (1), oplodiol (2), homalomenol A (3) and 1beta,4beta,7alpha-trihydroxyeudesmane (4) were isolated. These structures were elucidated and the(13)C-NMR chemical, shifts of these compounds were revised by means of various 2D-NMR techniques.
