Research on Relativity of Color with Contents of Anthocyanin,Flavonoids and Arotenoid in Plum

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.
