黄桃果实生长期是以叶绿素为主,成熟时叶绿素完全分解,类胡萝卜素急剧增多;绿色消失,而呈现黄色。吸收光谱、纸层析图谱和盐酸甲醇变色反应,一致表明黄桃不同品种(品系)成熟期,类胡萝卜素的主要组分相同;果实颜色的深浅与类胡萝卜的总量呈直线回归,与类胡萝卜素的各个组分的含量,无直线回归关系。 Peach fruit growth is the main chlorophyll, chlorophyll completely decomposed at maturity, a sharp increase in carotenoids; green disappeared, while showing yellow. Absorption spectra, paper chromatograms and methanol-HCl discoloration consistently indicated that the main components of carotenoids were the same at the ripening stage of different peach cultivars (lines); the color depth of fruit and the total amount of carotenoids showed a linear regression, Carotene content of each component, no linear regression.
