Effects of hecogenin on Larvicidal activity against Aedes aegypti mosquito, the dengue vector
Background Dengue is a viral disease, caused by the dengue virus, a Flaviviridae family virus. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti. The dengue control is based on the mosquito combat, most of time through chemical insecticides.

متن کاملLarvicidal activity and GC-MS analysis of flavonoids of Vitex negundo and Andrographis paniculata against two vector mosquitoes Anopheles stephensi and Aedes aegypti.
BACKGROUND & OBJECTIVES Development of insect resistance to synthetic pesticides, high operational cost and environmental pollution have created the need for developing alternative approaches to control vector-borne diseases. In the present study, larvicidal activity of flavonoid extracts of different parts of Vitex negundo (Linnaeus) and Andrographis paniculata (Nees) have been studied against...

متن کاملValidated HPLC method for identification and quantification of p-hydroxy benzoic acid and agnuside in Vitex negundo and Vitex trifolia
A high performance liquid chromatography coupled with photodiode array detection method was developed for the identification and quantification of p-hydroxy benzoic acid and agnuside in the extracts of Vitex negundo and Vitex trifolia. The separation was achieved using acetonitrile and O-phosphoric acid-water (0.5%, v/v) as the mobile phase in an isocratic elution mode. Mean retention times of ...
