The present investigation deals with the extraction, phytochemical constituent analysis and antioxidant activity analysis of Lantana camara. Solvents of varied polarity were employed for the extraction and it was observed that the yields of extraction depend on nature of solvent. Ethanol and methanol were the best possible solvents for having higher yields of the extract compared to other solvents chosen of varied polarities. Polyphenol content determination indicates that the ethanol and methanol extracts were found to have highest percent of polyphenols than other extracts. The Flavonoid estimation of the extracts indicate that methanol extract possess highest amount of flavonoids among all the extracts of different solvents. The DPPH inhibition activity analysis indicates that water extract evidenced to have potential antioxidant activity among all extracts of different solvents. This is probably due to the considerably high flavonoid content compared to other extracts. It is also clear that Lantana camara seems to have highly soluble compounds in ethanol and methanol; hence the yield is also high. Water extract emerges out as the best possible extract in terms of antioxidant activity. But methanol, ethyl acetate and ethanol extracts are shown to high higher yields. This investigation points out that the Lanatana camara contains significant amounts of antioxidant compounds such as polyphenols and flavonoids. Consequently various extracts showed potential antioxidant activity through DPPH free radical scavenging activity studies. Hence it is worth to consider Lantana camara for further exploration in utilizing it as rich antioxidant.
