ANALISA KANDUNGAN ANTOSIANIN PADA BUNGA MAWAR MERAH MENGGUNAKAN SPEKTROFOTOMETER (Analysis Of The Anthocyanin Content Of Red Roses Using A Spectrofotometer)

Abstract

Deposited roses too long about 4-5 days will wilt. The husband withered roses containing anthocyanin pigments. Anthocyaninsare a type of red-purple pigment from the flavonoid widespread ofvarious types plant. Anthocyanin is a natural pigment that gives the red color pigment belonging hearts late flavonoids and are generally used for the air so many potentially as a review of tea and natural dyes. Purpose of husband research is: (1) to review determine anthocyanin content of red roses on, (2) to determine the effect of heating with review variation sample weight against at extract color stability of red roses. The study was conducted husband with the extracting samples of ethanol 96% distilled water and citric acid. Extracts the tin is used to review the color stability test with using visible spectrophotometer. Results of research shows that the initials best condition or findings from heating maximum temperature of 60 OC and 6 gram sample weight linear with y=1,389x and R2 = -16.92. In addition effect of temperature and weight of the sample showed that more high-temperature heating and the big weight of the sample substance concentration colors the red rose flower extract high
