Phytochemical analysis of various essential oil of plant extract and its effect on mosquito repellent

Abstract

Mosquito causes severe human health diseases which may cause death of humans. It is responsible in causing sever diseases such as malaria, dengue, elephantitis etc. Thus, to overcome this problem many chemical repellents are being used. Longer time use of these chemical based repellent causes health issues that would be very harmful to humans. Thus, in this current investigation we are formulating herbal based mosquito repellent in order to avoid skin related problems, neurological disorders, and other health issues. The plants are the reservoirs of naturally occurring chemical compounds and structurally diverse bioactive molecules. Plants are recognized for their broad spectrum of pharmacological activities. The biological activities as secondary metabolites and phytochemicals derived from different plant parts as leaves, flowers, seeds, bark, root, and pulp. Current investigation suggests the beneficial use of various phytochemicals, essential oils and plant extracts that are used to kill mosquito. These phytochemicals such as alkaloid , flavonoid , saponoid , tannins , cardiac glycoside , glycoside , terpenoids , phenols , coumarins , phytosterol . These phytochemicals showed beneficial effects to overcome the use of chemical repellents. Our investigation showed alkaloid, flavonoid, saponoid phytochemicals as the best effective measure for killing of mosquito. Nature plant extracts and essential oils such as neem oil, camphor, coconut oil, orange peel, lemon grass oil, peeled oil etc. are used to formulate herbal mosquito repellent. Neem oil and lemon grass oil showed the best effective against mosquito. For further testing cage test was employed for Larvicidal activity. As a result, it showed 99% activity against mosquito that were gradually killed by the beneficial effects of essential oils and prominent plant extracts used in cage test.
