Abstract

The primary aim of this study was to screen non-toxic and easily available mosquito control biodegradable agent of botanical origin. Catharanthus roseus has been reported for various pharmaceutical properties for treating many ailments in Ayurveda. The ethanol leaf extract of the C. roseus possessed a significantly higher larvicidal activity against the 3rd instar larvae of Aedes aegypti than that of other extracts, with LC50 values of 157.8 ppm, respectively. The phytochemical screening and identification of phyto compounds present in the ethanolic extract of C. roseus leaves using gas chromatography-mass spectrometry (GC-MS) analysis revealed various phytocompounds. The preliminary phytochemical screening of the ethanolic leaf extract of C. roseus showed the presence of alkaloids, flavonoids, terpenoids, saponins, tannin, and protein and steroid.GC-MS chromatogram of the ethanolic leaf extract of C. roseus showed 15 peaks indicating the presence of 15 compounds. Among all the identified compounds, Hentriacontane possesses insecticidal, anti-candidal, anti-fungal and anti-inflammatory activities. Thus, ethanol leaf extract of the C. roseus possesses various potent bioactive compounds and can be used as potent natural mosquito larvicidal. Further studies are required for exploring its pharmaceutical properties.
