The flower constitutes flavonoid pigments. Flavonoids belong to the polyphenol group, which includes so many colouring pigments i.e. the anthocyanidin, flavones, flavanones, flavonols, etc. Anthocyanin is among the permitted pigments that can be used for food colourants and having been considered a potential replacement for synthetic dye. Some other flavonoids also enhance the colour of the anthocyanin as co-pigment. The objective of this study is to analyze the flower colouring pigments and their associated phytochemicals qualitatively and quantitatively at different developmental stages i.e. the matured bud (S-2), partially open flower (S-3), fully opened flower (S-4), petals starting to decay i.e. senescent flowers (S-5) of R. indica, H. rosasinensis, C. ternatea and M. jalapa. Percentage of petal-water content and pH of the cell-sap of the petal of test flowers were determined at different developmental stages. The experimental results noticed that petal of developmental stages are altered their water content and pH of the cell-sap. Among the flowers, the floral pigment content in petal exhibited the following order Clitoria ternatea > Rosa indica >Hibiscus rosasinensis > Mirabilis jalapa. The colour pigments viz. flavonoids, anthocyanins and phenol derivatives, protein, sugar and other nutrients present in petal of test flower might have act as potent colorant, antioxidant and neutraceuticals in food market. The procurement of color pigments from petal of the flower at appropriate level i.e. basing on developmental stage, is highly essential for further processing and manipulation through screening and evaluation. Pigment manipulation and utilization in food industry is a new field for sustainable health aspect and alternatives technology for better green environment.
