摘　　要： 从贵州黑糯米的稻米表皮中分别提取脂溶性色素、水溶性色素和脂肪酸．其中脂溶性色素经氧化镁柱层析和蔗糖柱层析分离纯化后，用光谱法鉴定分别有叶绿素ａ、α—胡萝卜素和β—胡萝卜素．而水溶性色素经硅胶Ｇ和纸层析分离纯化，用ＨＰＬＣ和薄层层析法分析糖分组成，结合光谱法鉴定分别有Ｃｎ—３—Ｇ和Ｃｎ—３—ＧＧ．脂肪酸用气相色谱法鉴定有亚油酸、棕榈酸和油酸。 Three water-soluble and three lipophilic pigments on the skin of Guizhou black glutious rice were purified. By comparing their absorption curves with the standard's under the same conditions, Cn-3-G and Cn-3-GG (from water-soluble pigment),α-carbotene,β-carbotene and Chlorophyll a (from lipophilic pigment) were confirmedrespectively. Three fatty acids on it were assayed by. gas-chromatograpby.
