title: Acetylated anthraquinone glycosides from Cassia obtusifolia.
abstract: Three new acetylated anthraquinone glycosides (1-3) were isolated from the seed of Cassia obtusifolia, together with one parent anthraquinone glycoside (1a). Their structures were determined on the basis of spectroscopic methods and physicochemical properties as obtusifoline-2-O-β-d-2, 6-di-O-acetylglucopyranoside (1), obtusifoline-2-O-β-d-glucopyranoside (1a), obtusifoline-2-O-β-d-3, 6-di-O-acetylglucopyranoside (2), and obtusifoline-2-O-β-d-4, 6-di-O-acetylglucopyranoside (3).
