Vernonia anthelmintica is a wild medicinal herb distributed throughout the India. It is used as a folk medicine against cough, skin diseases, diarrhea and fever. In the present study, ethanolic extract was obtained from seeds of Vernonia anthelmintica and phytochemical analysis was done to screen alkaloids, saponins, steroids, carbohydrates, flavonoids, glycosides, polyphenols and gums and muci...

BACKGROUND Mosquitoes are well known as vectors of several disease causing pathogens. The extensive use of synthetic insecticides in the mosquito control strategies resulted to the development of pesticide resistance and fostered environmental deterioration. Hence in recent years plants become alternative source of mosquito control agents. The present study assessed the larvicidal and ovipositi...

Methanolic extracts from 15 medicinal plants representing 11 families, used traditionally for malaria treatment in Kenya were screened for their in vivo antimalarial activity in mice against a chloroquine (CQ)-tolerant Plasmodium berghei NK65, either alone or in combination with CQ. The plant parts used ranged from leaves (L), stem bark (SB), root bark (RB), seeds (S) and whole plant (W). When ...

The plants of the genus Vernonia (Asteraceae) are widely distributed in most tropical and subtropical countries, and have long been used in traditional medicine to treat various types of diseases. In recent years, the interest in the plant-based medicine has increased noticeably worldwide. In the present study we evaluated the anticataleptic efficacy of ethanol extract of Vernonia cinerea L. in...

A simple, precise and accurate high-performance liquid chromatographic method has been developed for simultaneous determination of β-sitosterol and Lupeol in whole plant powder of Vernonia cinerea Linn. Chromatographic separation of the two compounds was performed on a waters symmetry shield C18 column (150 x 4.6, 5 μm) as stationary phase with a mobile phase comprising of methanol : acetonitri...

The aim of my research was to screen secondary metabolites and antimicrobial activities of methanolic extracts of the leaves Vernonia amygdalina and Plantago lanceolata, and acetone extracts of the leaves Rosmarinus officinalis and Thymus schimperi against two bacteria (Staphylococcus aureus and Escherichia coli) and two fungi (Aspergillus niger and Fusarium oxysporum) using paper disc diffusio...

A rapid and efficient protocol was developed for inducing direct organogenesis using shoot tip explants of Vernonia cinerea L. Shoot tip explants were cultured on MS medium supplemented with different concentrations of BAP (2.22 to 22.20 μM/l) and KN (2.42 to 23.20 μM/l) for direct shoot induction. The frequency of multiple shoot induction and proliferation increased with increasing concentrati...
