Unformatted text preview: NATURAL PRODUCT RESEARCH Khalijah Awang 23rd-25th June 2010 Chemistry Department, University Of Malaya, 50603 Kuala Lumpur, Malaysia E-mail: khalijah@um.edu.my Malaysia is blessed with one of the most diversed a nd oldest flora in the world. In addition, our multicultural society is rich in traditional medicine heritage from three different races; Malay, Chinese and Indian. Thus the rich flora coupled with traditional medicine heritage, research in Natural Product s is of great importance to our country. Research in this area could help us understand the medicinal treasure of our nation scientifically and can also help us to discover new bio -active compounds that can be used as leads in drug development. This presen tation shall briefly discuss on the strategies that can be taken in Natural Product Research to get new lead compounds such as meiogynin, walsogyne A, delaumonones A, maingayone B and also maingayone C to discover the active ingredient/s of plants used in our traditional medicine.

The unique combination of the cations and anions give low melting points, high thermal stability, liquidity over a wide temperature range, negligible vapor pressures, low inflammability, highly solvating capacity for both polar and non polar compounds and high electrical conductivity. ILs are receiving much attention in many important areas of research...
