黄瑞木果实红色素的分离及其化学结构研究

Studies on separation and chemical structure identification of red pigment of Adinandra millettii fruit

采用纸层析、紫外-可见光谱、红外光谱和液-质联用等技术对福建野生黄瑞木〔Adinandra millettii(Hook. et Arn.)Benth.〕果实红色素进行了分析研究。结果表明,该红色素主要含有矢车菊素-3-芸香糖苷(cyanidin-3-rutinoside)和矢车菊素-3-葡萄糖苷(cyanidin-3-glucoside)2种花色苷,呈鲜艳的红色,可作为天然保健食品的色素添加剂加以推广应用。

Paper chromatography （ PC ）, ultraviolet-visual spectrum （ UV ）, infrared spectrum （ IR ） and high pressure liquid chromatography-mass spectrometry （HPLC-ESI-MS） were used to separate and identify the red pigment from wild Adinandra millettii （ Hook. et Am. ） Benth. fruit in Fujian Province. The results showed that the red pigment is composed of two anthocyanins which are cyanidin-3-rutinoside and cyanidin-3-glucoside in bright red color and it can be used as an additive in natural health food.
