Abstract

The effects of pH, number of storage days, temperature, light and dark conditions on the stability of anthocyanin extracted from Tibouchina semidecandra flowers of different developmental stages were evaluated. Fully formed but unopened flower bud exhibited the highest amount of total anthocyanin extracted from per gram fresh weight of petals. The anthocyanin contents for all flower developmental stages were stable at pH 0.5 to 3.0 but the colour of the extracts faded at higher pH values. Degradation percentages of total anthocyanin in the extracts kept at 25ºC were 7 to 20% lower than that maintained at 31°C. Extracts stored in darkness at 25ºC maintained their purple colour for 16 days while light exposure reduced it to an average of 10 days.
