摘要
目的 : 对白果中类胡萝卜素进行分析与鉴定。方法 : 可见光吸收光谱特性分析证实白果中色素成分为类胡萝卜素 ;比色法测定了其含量 ;分别采用薄层色谱和高效液相色谱分离白果中类胡萝卜素 ,并鉴定其成分及组成。结果 : 白果中含类胡萝卜素总量约 489μg/1 0 0 g;其中叶黄质、β-胡萝卜素和 α-胡萝卜素 ,分别占总类胡萝卜素的 6 9.2 0 %、1 5 .80 %和 7.45 %。结论 :白果含大量类胡萝卜素 ,以叶黄质为主 ,其次为 β-和 α-胡萝卜素。
Objective: To analyze and identify the carotenoid in gingko seed.Methods: The chemical composition of the pigment from gingko seed was identified as carotenoid by UV absorption spectrum. Its content was determined by spectrophotometric method and its composition was analyzed and identified by thin-layer chromatography and HPLC method.Results: Gingko contained carotenoids, roughly about 489 μg/100 g in which lutein, β-carotene and α-carotene amounted to 69.20%,15.80% and 7.45% respectively. Conclusion: Gingko contained large quantity of carotenoids, mainly lutein, and next in order β-carotene and α-carotene.
