RESUMO
<p><b>OBJECTIVE</b>To investigate the antioxidant activity of methanolic extracts of Lantana camara (L. camara) various parts and the determination of their total phenolics content.</p><p><b>METHODS</b>The extract was screened for possible antioxidant activities by free radical scavenging activity(DPPH), xanthine oxidase inhibition activity and Griess-Ilosvay method.</p><p><b>RESULTS</b>The results showed that all the plant parts possessed antioxidant properties including radical scavenging, xanthine oxidase inhibition and nitrites scavenging activities. The antioxidative activities were correlated with the total phenol. The leaves extract of L. camara was more effective than that of other parts.</p><p><b>CONCLUSIONS</b>This study suggests that L. camara extracts exhibit great potential for antioxidant activity and may be useful for their nutritional and medicinal functions.</p>

<p><b>OBJECTIVE</b>To investigate the toxicity of methanol extract of various parts (Root, Stem, Leaf, Flower and Fruit) of Lantana camara (L. Camara) in Artemia salina.</p><p><b>METHODS</b>The methanol extracts of L. camara were tested for in vivo brine shrimp lethality assay.</p><p><b>RESULTS</b>All the tested extract exhibited very low toxicity on brine shrimp larva. The results showed that the root extract was the most toxic part of L. camara and may have potential as anticancer agent.</p><p><b>CONCLUSIONS</b>Methanolic extract of L. camara is relatively safe on short-term exposure.</p>
