PHYTOCHEMICALS SCREENING AND ACID- BASE INDICATOR PROPERTY OF ETHANOLIC EXTRACT OF ALTHEA ROSEA FLOWER

Abstract

Secondary metabolites are unwanted compounds released by plants during excretion process but some of them are also used by the plants as protective agents. The presences of these compounds were reported to have medicinal properties. In the present study phytochemicals screening of the ethanolic extract of Althea rosea flower (garden hollyhock) revealed the presence of alkaloids, flavonoid, triterpinoids, saponins, tannins, cardiac glycoside, and phenolic compounds. Indicators currently in-used cause environmental pollution and they are hazardous to the living organism. The ethanolic extract of Althea rosea flower (garden Hollyhock) shows a perfect colour change at equivalent point during acid base titration as compared with synthetic indicators. Therefore the extract from this flower could be used as replacement for both methyl orange and phenolphthalein in neutralization reaction.
