Abstract

Phytochemical investigations of the aerial parts of Acacia pennata (Mimosaceae) from Myanmar led to the isolation of five flavonoid glycosides and six known compounds. The new compounds were identified as (2R,3S)-3,5,7-trihdyroxyflavan-3-O-α-L-rhamnopyranoside, (2S)-5,7-dihydroxyflavan-7-O-β-D-glucopyranoside-(4α → 8)-epiafzelechin-3-O-gallate, (2R)-4',7-dihydroxyflavan-(4α → 8)-(2R,3S)-3,5,7-trihdyroxyflavan-3″-O-α-L-rhamnopyranoside, 5,7-dihydroxyflavone 6-C-β-boivinopyranosyl-7-O-β-D-glucopyranoside, and 5,7-dihydroxyflavone 7-O-β-D-glucopyranosyl-8-C-β-boivinopyranoside based on interpretation of spectroscopic data.

摘要

对缅甸羽叶金合欢（含羞草科）地上部分进行的植物化学研究，分离出了5种黄酮苷和6种已知化合物。根据光谱数据解析，新化合物被鉴定为(2R,3S)-3,5,7-三羟基黄烷-3-O-α-L-鼠李吡喃糖苷、(2S)-5,7-二羟基黄烷-7-O-β-D-葡萄糖吡喃糖苷-(4α→8)-表阿夫儿茶精-3-O-没食子酸酯、(2R)-4',7-二羟基黄烷-(4α→8)-(2R,3S)-3,5,7-三羟基黄烷-3″-O-α-L-鼠李吡喃糖苷、5,7-二羟基黄酮6-C-β-波伊文吡喃糖基-7-O-β-D-葡萄糖吡喃糖苷以及5,7-二羟基黄酮7-O-β-D-葡萄糖吡喃糖基-8-C-β-波伊文吡喃糖苷。
