EXTRACTION AND CHARACTERISATION OF MUCILAGE FROM THE LEAVES OF HIBISCUS ROSA-SINENSIS LINN. (MALVACEAE)Abstract
Plant mucilages have found wide application in food, pharmaceutical and cosmetic industries. Hence, it would be worthwhile to characterise the physical and chemical attributes of mucilages from commonly available plants for their beneficial utilization. Hibiscus rosa-sinensis Linn. (Family Malvaceae), widely grown as an ornamental throughout the tropics and subtropicsis a good source of mucilage. The present study focuses on the extraction of the mucilage from the leaves of Hibiscus rosa-sinensis, its subsequent quantification and physico-chemical characterisation. A protocol was presently standardized for the yield optimization of mucilage from Hibiscus through detection of an appropriate maceration temperature and precipitation solvent. Further analyses revealed ideal pH value, swelling index, flow properties and particle size of Hibiscus mucilage. Moreover, chemical, FTIR spectral and electrokinetic data of Hibiscus mucilage revealed that it can be considered as a suitable blending ingredient in composites with potential industrial applications.
