鬼灯擎根茎中丹宁及多元酚类化合物的分离与鉴定（I）

ISOLATION AND CHARACTERIZATION OF TANNIN AND RELATED POLYPHENOLSFROM THE RHIZOME OF RODGERSIA AESCULIFOLIA BATAL

采用室温组织破碎提取、闪蒸浓缩及ＤｉａｉｏｎＨＰ—２０和ＴｏｙｏｐｅａｒＩＨＷ—４０反复柱层析，从鬼灯擎根茎的７０％Ｍｅ＿２ＣＯ提取物中分离得到三种酚性化合物，称ＲＡ—Ｉ～Ⅲ，经化学反应及１￣ＨＮＭＲ，（１３）￣ＣＮＭＲ分析，确定该三种化合物分别是岩白菜素（ｂｅｒｇｅｎｉｎ，ＲＡ—Ⅱ，１），（＋）—儿茶素（ｃａｔｅｃｈｉｎ，ＲＡ—Ⅱ，２）和原花色甙元Ｂ—２单没食子酸酯（ｐｒｏｃｙａｎｉｄｉｎＢ—２ｍｏｎｏｇａｌｌａｔｅ，ＲＡ—Ⅲ，３）。ＲＡ—Ⅱ及ＲＡ—Ⅲ为首次从该植物中得到。
