摘要:
为研究李果果皮、果肉色泽与花色素苷、类黄酮和类胡萝卜素含量的关系,以14个李品种为试验材料,测定果皮、果肉色泽(LCH0色空间),果皮、果肉中花色素苷、类黄酮和类胡萝卜素的含量;比较不同品种果皮、果肉色泽及花色素苷、类胡萝卜素和类黄酮含量间的差异;分析色泽与花色素苷、类胡萝卜素和类黄酮含量间的关系。结果表明:果皮、果肉色泽的色调角(H0)所显示的颜色与肉眼观察结果基本一致,可以作为指示色泽的重要指标;果皮、果肉中富含花色素苷、类黄酮和类胡萝卜素,不同品种间三者的含量均存在极显著差异;亮度(L)与果皮、果肉中花色素苷、类胡萝卜素含量均呈显著负相关(P<0.01),且果肉色泽的色调角(H0)亦与二者有极显著负相关关系(P<0.01),而饱和度(C)与之没有明显相关性;三者与类黄酮含量均没有明显相关性。

Abstract:
To research the relativity of color with contents of anthocyanin,flavonoids and arotenoid in plum,the study detected and compared the color(LCH0),contents of anthocyanin,flavonoids and carotenoid for peel and flesh of 14 plum varieties.It also analyzed the relativity of color with contents of anthocyanin,flavonoids and carotenoid.The results indicated:First,hue angle(H0)was a important indicator index of color because it suggested the similar consequence as eyes on color.Second,the contents of anthocyanin,flavonoids and carotenoid were rich in plum peel,and also in plum flesh.They were highly different among varieties(P<0.01).Third,The luminance(L),both of peel and flesh,had significant negative correlation with the contents of anthocyanin and carotenoid,respectively(P<0.01);what's more,it presented an identical tendency between H0 of flesh with the conetents of anthocyanin and carotenoid(P<0.01),respectively;but color saturation(C)was not obviously correlated with the two contents(P>0.05),respectively.However,the correlations of L,C and H0 with content of flavonoids were not obvious(P>0.05),respectively.
