ABSTRACT

Chrysophanol, physcion, emodin, floribundone-1, 5,7'-physcion-fallacinol, and the novel 5,7'-physcion-physcion-10'-C-alpha-arabinopyranoside were isolated from the stem bark of Senna septemtrionalis. The structures of these secondary metabolites were determined on the basis of spectroscopic analysis, especially from NMR spectra in conjunction with COSY, HMQC, HMBC and TOCSY.
