| 摘 要： | 为研究天然绿色棉纤维的色素成分，将绿色棉纤维粉碎后采用乙醇溶剂浸提色素。提取液利用碱溶酸沉法纯化后，通过红外、紫外光谱仪对色素特性进行测定。通过对色素甲醇溶液加入HCl／Zn、AlCl3、FeCl3、硼酸、NaBH1、醋酸镁、柠檬酸、浓硫酸之后的显色反应推断绿色棉色素属类黄酮化合物，并根据色素甲醇溶液加入诊断试剂后的紫外光谱推断出绿色棉色素是A环具有6、7-OH、5-OCHs，B环含有3’，4’-OH，并且3-OH被取代的黄酮醇类化舍物。

| Abstract: | For the study of pigment＇s composition in naturally green cotton, the naturally green cotton is pulverize by a grinder, and fiber powder is extracted in ethanol and extracts is purified by their different solubilities in acid/base solution. The infrared spectrum, UV spectrum are used for analysis the structure of the pigment from extracts. The results show that green cotton pigment is probable of the member of flavonoids according to the physicochemical property of the pigment and the green cotton pigment has 6, 7- OH, 5-OCH3 in ring A and 3＇, 4＇-OH in ring B, in addition 3-OH is possibly substituted. |
