Five fungicides such as rovral, bavistin, cupravit, dithane M-45 and thiovit were tested against conidial germination of Fusarium oxysporum. Dithane M-45 was the most effective against the fungus. Rests of the fungicides were more or less effective in the inhibition of conidial germination after 5~30 minutes immersion in 500~2500 ppm concentration. Five plant extracts(leaf extracts of Ocimum sanctum, Lantana camera, Calotropis procera, Azadirachta indica and Vinca rosea) found to be more or less effective against the fungus. 'Dhup' somke have good inhibitory effect on conidial germination of F. oxysporum.

OBJECTIVETo investigate the toxicity of methanol extract of various parts (Root, Stem, Leaf, Flower and Fruit) of Lantana camara (L. Camara) in Artemia salina.

METHODSThe methanol extracts of L. camara were tested for in vivo brine shrimp lethality assay.

RESULTSAll 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.

CONCLUSIONSMethanolic extract of L. camara is relatively safe on short-term exposure.

OBJECTIVETo investigate the antioxidant activity of methanolic extracts of Lantana camara (L. camara) various parts and the determination of their total phenolics content.

METHODSThe extract was screened for possible antioxidant activities by free radical scavenging activity(DPPH), xanthine oxidase inhibition activity and Griess-Ilosvay method.

RESULTSThe 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.

CONCLUSIONSThis study suggests that L. camara extracts exhibit great potential for antioxidant activity and may be useful for their nutritional and medicinal functions.
