Bioactive compounds present in the medicinal plants which are anti larvicidal activity against dengue and malarial vector. Phytochemicals, which are in two categories - primary and secondary. Medicinal plants have anti-fungal, anti-bacterial and anti-inflammatory. The present study involves phytochemical analysis of selective plants. The leaf of plants such as Carica papaya, Azadirachta indica, Ocimum sanctum, Cymbopogan citratus, Mentha spicata, Aloe vera, Vitex negundo, Plectranthus amboinicus, Senna auriculata and Manilkara zapota, bulb of Allium sativum and flower of Targetes erecta was washed, air dried aqueous and ethanol extract of leaf 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. Also analysis the larvicidal activity of medicinal plants in larvae of Aedes and Anopheles in aqueous and ethanol extracts and recorded the mortality rate in 24 and 48 hours.
