Preliminary phytochemical screening and antimicrobial evaluation of three medicinal plants used in Nigeria

Preliminary phytochemical screening and antimicrobial evaluation of three medicinal plants used in Nigeria.

Methanol extract of three Nigerian medicinal plants were screened for antimicrobial activity using modified Kirby-Bauer disc diffusion and agar dilution techniques to determine the diameters of zone of inhibition and minimum inhibitory concentrations (MIC) of the extracts respectively. The extract of each of the plants were tested against five clinical bacterial isolates comprising of two Gram-...

Preliminary phytochemical screening of selected Medicinal Plants

Preliminary Phytochemical Screening of Six Medicinal Plants Used in Traditional Medicine

Objective: Preliminary screening of phytochemicals is a valuable step, in the detection of the bioactive principles present in medicinal plants and subsequently may lead to drug discovery and development. In the present study, chief phytoconstituents of the six selected medicinal plants of different families were identified in order to relate their presence with bioactivities of the plants. Met...

Antimycobacterial evaluation and preliminary phytochemical investigation of selected medicinal plants traditionally used in Mozambique.

AIMS OF THE STUDY It was aimed to assess the in vitro antimycobacterial activity of crude extracts from fifteen medicinal plants and to reveal main classes of compounds which may account for the activity of extracts. METHODS AND MATERIALS The plant materia...

Preliminary phytochemical screening of some Indian Medicinal Plants

Alkaloids, tannins, saponins, steroid, terpenoid, flavonoids, phenolic compounds and cardie glycoside distribution in five medicinal plants belonging to different families were assessed and compared. The medicinal plants investigated were Asteracantha longifolia (L.) Nees, Psassiflora edulis Sims, Berberis tinctoria Lesch, Sphaeranthus indicus Linn, and Solanum trilobatum Linn. All the plants w...
