Abstract

Pigment Antosianin of red kana flower represent pigment group of flavonoid dissolved in water, and yellow kana flower contain pigment of antosantin which also flavonoid that has yellow color at corolla, like yellow dahlia, alamanda. The objective of this research was to know the sugar type where found in red and yellow kana flower pigment and also to know quality each pigment where contains in red and yellow kana flower. This research was conducted in 2 phases compile as follows: Phase I, Identify sugar type on red kana flower and yellow kana flower using method of paper chromatography by observe Rf value (Retrogradation Factor) phase move BEA (n n-BuoH-EtOH-H2O (4 n : 1 : 2,2)). Phase II, the Quality of each pigment from red kana flower and yellow kana flower. Parameter observed include observation to filtrate (pH, absorbance, color intensity (L,a,b)), to concentrate (pH, absorbance, color intensity (Rate pigment L,a,b), rendemen and sugar identify (paper chromatography)). The result of research known that pigment of red kana flower contains sugar type for example ramnosa, glucose, glukoronat, and apiosa while in the yellow kana flower contains the sugar type, that is glucose, ramnosa, galaktosa, xilosa and arabinosa. Pigment of red kana flower has sugar component with top absorbance at λ 265,0 nm while on pigment of yellow kana flower to be detected by top absorbance at λ 230 nm as glikon For the intensity of color of filtrate pigment of red kana flower has L value (29,63), a+ value (16,03) and b+ value (1,00) while on concentrate has L value (27,6), a+ value (4,97) and b+ value (1,10). For the filtrate pigment of yellow kana flower has L value (45,97), a+ value (3,8) and b+ value (12) while on concentrate has value L (33,8), value a+ (5,33) and value b+ (4,97). Pigment Filtrate of red kana flower has pH value 2,60 and concentrate 2,41 while filtrate of yellow kana flower has pH value 5,23 and on concentrate 5,39. Pigment of red kana flower has absorbance value of filtrate 2,50 A and concentrate 11,39 A at 513,3 nm, while yellow kana flower has absorbance value of filtrate 0,522 A and concentrate 0,522 A at 364,9 nm. Pigment of red kana flower has rate of antosianin 0,90 mg / ml. Pigment Rendemen of red kana flower 12,04% while pigment rendemen of yellow kana flower 12,75%.
