Two new ellagic acid glycosides were isolated from Punica granatum L. (Lythraceae) pericarps and identified using UV and NMR spectroscopy and mass spectrometry as 1,6′-di-O-ellagoylgentiobiose (granatoside A, 1) and 1,6-di-O-ellagoyl-β-D-glucopyranose (granatoside B, 2). Compounds 1 and 2 exhibited α-glucosidase inhibitory activity.
从石榴(Punica granatum L.,鼠尾草科)的果皮中分离出两种新的鞣酸苷,并通过紫外光谱、核磁共振光谱和质谱鉴定为1,6′-二-O-鞣酸黄酮糖二糖(granatoside A,1)和1,6-二-O-鞣酸-β-D-葡萄糖吡喃糖(granatoside B,2)。化合物1和2表现出α-葡萄糖苷酶抑制活性。
