Abstract A new isoflavone glycoside, named 3’-hydroxytectorigenin-7-O-β-D-xylosyl-(1→6)-β-D-glucopyranoside (1) was isolated from the flowers of Pueraria montana var. lobata (Willd.) Sanjappa & Pradeep. The structure of compound 1 was characterised by HR-ESI-MS and NMR spectroscopic methods. In radical scavenging activity test using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), compound 1 showed moderate
摘要 从葛根的花中分离到一种新的异黄酮糖苷,名为3'-羟基肌生成素7- O -β-D-木糖基-(1→6)-β-D-吡喃葡萄糖苷(1)。lobata(Willd。)Sanjappa和Pradeep。化合物1的结构通过HR-ESI-MS和NMR光谱法表征。在使用2、2-二苯基-1-吡啶并肼基(DPPH)进行的自由基清除活性测试中,化合物1表现出中等活性,IC 50值为42±4.2μg/ mL。
