Abstract

Anthocyanins are water soluble vacuolar pigments that, depending on their pH, may appear red, purple, or blue found in plants. In the current study anthocyanin colors were extracted from locally available flowers of the Pyrostegia venusta, Butea monosperma, Cassia auriculata, Tecoma stans and Woodfordia fruticosa using acidified methanol as a solvent. Obtained extracts were evaluated for their phytochemicals and assessed for its bioactivity such as antimicrobial (E coli, Staphylococcus aeries and Bacillus subtilis) and antioxidant properties. This flower extracts has shown considerably significant activities along with their coloring property. The results show the potential usage of these natural colorants in various coloring applications including food coloration, alternative to synthetic colors. The study also explores the utilization of easily available sources and value addition to waste products. Key words: Anthocyanin, Natural colorant, Medicinal plants, Antioxidants, Antimicrobials.
