Abstract

Three new acylphloroglucinol glycosides, namely pyrafortunosides A (1), B (2) and C (3), together with three known glycosides (4-6), were isolated from the fruits of Pyracantha fortuneana (Maxim.) Li. Their structures were established to be 2,4,6-trihydroxy-acetophenone-6-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (1), 2,4,6-trihydroxy-benzophenone-6-O-alpha-L-rhamno-pyranosyl-(1-->6)-beta-D-glucopyranoside (2), 2,4,6-trihydroxy-benzophenone-6-O-beta-D-apiofuranosyl-(1-->6)-beta-D-gluco-pyranoside (3), garcimangosone D (4), 2,4,6-trihydroxy-acetophenone-6-O-beta-D-glucopyranoside (5), and 2,4,6-trihydroxy-acetophenone-4-O-beta-D-glucopyranoside (6) by spectral analysis. The three known glycosides (4-6) were obtained from this genus for the first time.
