Abstract:
Two novel C glycosylflavones, apigenin-6-C-α-L-arabinopyranosyl-(1-4)-α-L- rhamnopyranoside (hemsleyanoside, 1) and apigenin-8-C-α-L-arabinopyranosyl-(1-4) –α-L-rhamno-pyranoside(isohemsleyanoside), together with a known compound (apigenin-6,8-di-C-β-D-glucopyranoside, 3), were isolated from the 95% EtOH extract of Tetrastigma hemsleyanum Diels et Gilg. Their structures were elucidated by chemical evidence and spectral analysis.

摘要:从三叶崖爬藤(Tetrastigma hemsleyanum Diels et Gilg.)的95%乙醇提取物中分离得到3个黄酮碳甙,经化学方法和光谱分析鉴定为:5,7,4′-三羟基黄酮-6-α-L-吡喃鼠李糖(1-4)-α-L-吡喃阿拉伯糖甙(1),5,7,4′-三羟基黄酮-8-α-L-吡喃鼠李糖(1-4)-α-L-吡喃阿拉伯糖甙(2),5,7,4′-三羟基黄酮-6,8-二-C-β-D-吡喃葡萄糖甙(3),1和2为新化合物,分别命名为崖爬藤甙和异崖爬藤甙.
