Medicinal plants are finding their way into pharmaceuticals, cosmetics, and neutraceuticals. Approximately 20% of the plants found in the world have been submitted to pharmaceutical or biological test and a sustainable number of new antibiotics introduced in the market are obtained from natural or semi synthetic resourcesPL Thus it is a logical approach in drug discovery to screen traditional natural products. Most of the drugs today are obtained from natural sources or semi synthetic derivatives of natural products used in the traditional systems of medicine.
