insoluble in water, with a melting point higher than 192ºC and optical absorption<br />
maximum of 452 nm.<br />
In the proposed project, few experiments may be conducted to estimate the<br />
antioxidant activity of lawsone and comparison studies may also be studied with natural<br />
antioxidant vitamins like Vitamin C and E. The developed electrochemical methods may<br />
be further extended to determine the antioxidant activity and purity of lawsone in henna<br />
leaves and on selected henna herbal products. To make use of current electrochemical<br />
analytical techniques like potentiometry, the antioxidant activity may be determined<br />
precisely with reference compounds.<br />

<strong>1.</strong> To design and synthesize stilbene derivative(s) with potential anti-cancer activity<br />
Abstract<br />
It has been great interest in the study of stilbene derivatives for their biological<br />
activities such as antileukemic, anti-cancer activity i . Stilbene itself is not a natural<br />
product although naturally occurring stilbenoid compounds such as<br />
polyhydroxystilbenes and their glucosides have been is present in grape vine, Southeast<br />
Asian Timber trees. For instance, naturally hydroxylated stilbene, resveratrol<br />
(figure 1) is well known for heart protecting activity, platelet antiaggregating<br />
capability, herpes simplex viruses inhibition, cancer chemopreventive activity and<br />
anti-oxidative activity ii .<br />

Resveratrol is indeed the biosynthetic precursor of most oligostibenoids (e.g<br />
viniferins) and is classified as phytoalexins. Consequence, resveratrol and its<br />
analogues present minute amounts in plants as it occurs during the stress situation<br />
of the pant. Therefore, other alternative sources of supply on stilbene derivatives<br />
through retrosynthesis have been interested. Furthermore, resveratrol has been<br />
shown to induce apoptosis in different cancer cell lines.<br />
