摘要
研究了玉米须中的黄酮苷类成分。通过硅胶柱层析和Sephadex LH-20层析对玉米须乙酸乙酯提取物初步纯化,采用液相色谱-质谱联用法对其中的黄酮苷类化合物进行分析。结果表明,玉米须乙酸乙酯提取物中含有3种黄酮苷类化合物,分别为5,7,4'-三羟基-3'-甲氧基黄酮-6-C-2″-O-二鼠李糖苷、5,7,4'-三羟基-3'-甲氧基黄酮-3-C-阿拉伯糖-6-C-鼠李糖苷和ax-5″-甲烷-3'-甲氧基玉米素。
Composition of flavonoid glycosides in corn silk were analyzed in this study. Ethyl acetate ex- tractive of corn silk was purified by the silica gel column and sephadex LH-20 column chromatography. Flavonoid glycosides in corn silk were analyzed by HPLC-MS. Results showed that ethyl acetate extractive of corn silk had three kinds of flavonoid glycosides, which were 5,7,4′-trihydroxy -3′-methoxyflavone-6- C-2＂-O-dirhamnoside, 5,7,4′-trihydroxy-3′-methoxyflavone-3-C-arabinose-6-C-rhamnoside, and ax-5＂- methane-3′-methoxymaysin were analyzed by HPLC-MS.
