Abstract

Malaria is very dangerous disease mainly caused by Anopheles mosquito. Phytochemical compounds present in the medicinal plants which are anti larvicidal activity against this malarial vector. The plants parts were washed, air dried and aqueous, acetone ethanol extracts of plant sample were used for the phytochemical analysis to find out the phytochemical constituents in the plant such as alkaloid, glycoside, phytosterol, flavonoid, phenol, protein and carbohydrate. The plant extracts from 12 medicinal plants species to larvae of Anopheles were determined in the laboratory response varied according to plant extracts and mosquito larvae. At the concentration of 50 ppm 100 percent mortality was obtained with a extracts of Carica papaya, Azadirachta indica, Ocimum sanctum, Mentha spicata, Aloe vera, Vitex negundo, Plectranthus amboinicus, Targetes erecta, Manilkara zapota, and Allium sativum Carica papaya, Azadirachta indica, Ocimum sanctum, Mentha spicata, Aloe vera, Vitex negundo, Plectranthus amboinicus, Targetes erecta, Manilkara zapota, and Allium sativum respectively. The plants described merit further study as potential mosquito larval control agent.

Keywords: Medicinal plants, phytochemical analysis and larvicidal activities.
