A. Rahuman Active Principles in Plants The active principles in medicinal plants are chemical compounds known as secondary plant products. Some secondary products discourage herbivores, others inhibit bacterial or fungal pathogens. Two major categories of these compounds are alkaloids and glycosides. 1 Alkaloids More than 3,000 alkaloids have been identified in 4,000 plant species; most occur in herbaceous dicots and also in fungi. Alkaloids contain nitrogen, they are usually alkaline (basic), and they have a bitter taste.

In India, malaria is transmitted by nine anopheline vector species of which six are of primary importance. The primary vectors include Anopheles culicifacies, A. stephensi, Anopheles fluatilis, Anopheles minimus, Anopheles gyrus, and Anopheles sundicus. These species are responsible for transmission in specific ecotypes. Of the six primary vector species, A. culicifacies is squarely responsible for transmission of about 60–70% of the malaria in rural plains and peri-urban areas (Raghavendra and Subbarao 2002).
