Two new aurone glycosides, 6 hydroxy 5 methyl 3',4',5' trimethoxy aurone 4-O-alpha-L-rhamnopyranoside and 6,4' dihydroxy aurone 4-O-rutinoside have been isolated from the ethanolic extract of the wood of Pterocarpus santalinus. Their structures were determined on the basis of chemical and spectroscopic analysis (UV, IR, EIMS, (1)H and (13)C NMR).
已从木材的乙醇提取物中分离出两种新的金糖苷,6 羟基 5 甲基 3',4',5' 三甲氧基金糖苷 4-O-α-L-鼠李糖苷和 6,4' 二羟基金糖苷 4-O-芸香糖苷紫檀。它们的结构是在化学和光谱分析(UV、IR、EIMS、(1)H和(13)C NMR)的基础上确定的。
