摘要
采用溶剂提取法和硝酸/乙醇(1∶4)氧化法提取天然彩色棉纤维的色素.通过色素提取液的光谱分析得出,天然棕色棉纤维色素成分为黄酮类化合物,B环上带有邻二酚羟基;天然绿色棉纤维色素中除含有黄酮类化合物外,A、B环上都带有邻二酚羟基.
In this paper, the test of the spectral analysis of pigment extraction in naturally colored cotton is carried. The pigment in mature naturally colored cotton fibers is extracted by solvent and nitrate / ethanol （1 ： 4） . The results of UV spectral analysis shows that the pigment extracted from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring,and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring.
