摘　　要：A new anthraquinone glycoside 1, along with a known anthraquinone glycoside aurantio-obmsin-6-O-β-D-glucopyranoside 2, were isolated from the seeds of Cassia obtusifolia. On the basis of spectral and chemical evidences, the structure of 1 was established as 1-demethylaurantio-obtusin-2-O-β-D-glucopyranoside. Moreover, the 13C NMR of 2 was assigned totally and correctly for the first time based on the two-dimensional NMR.A new anthraquinone glycoside 1, along with a known anthraquinone glycoside aurantio-obmsin-6-O-β-D-glucopyranoside 2, were isolated from the seeds of Cassia obtusifolia.
