Bio-pigment extraction from blue-color flowering landscape ornamentals

Abstract

The plants used in landscaping, which typically grow in the wild, along roads, or on homestead land, produce flowers in different shades of colors, from which pigments in other hues can be derived. In this study, six aqueous extraction techniques were used to extract pigments from three plant species, Lagerstroemia sp., Clitoria sp., and Eichhorniacrassipesthat, which produce blue-colored flowers. This study aimed to standardize the processes for extracting pigments from flowers of naturally occurring plant species, identify potential sources of blue-colored natural pigments and assess the durability and quality of the pigments. Clitoria sp. had the highest anthocyanin concentration (64.44 mg/l) when extracted with microwave assistance.
