Comparative study on phytochemical properties, antibacterial and antioxidant activities of different solvent extracts of twelve selected medicinal plants / Norsuhana Sapiee and Marlina Mohd Mydin

The present study was undertaken to evaluate the phytochemical properties and to study the antibacterial and antioxidant activities of different solvent extracts (ethanol, methanol, water and hexane) of medicinal plants. twelve medicinal plants were selected and the presence of bioactive compounds (flavonoid, terpenoid and alkaloid) were analyzed. Both evaluations of antibacterial and antioxidant activities were based on the detection of zone of inhibition and the detection of antioxidant activities by different solvent extracts, respectively. The selected medicinal plants for this study were Euphorbia wallichii, Hypochaeris radicata, Boerhaavia diffusa Linn, Tinospora cardifolia, Eclipta alba, Heliotropium bacciferum, Crotalaria pallida, Hibiscus sabdariffa, Lantana camara, Sida rhombifolia, Cirsium wallichii, and Pogostemon benghalensis. The results of phytochemical properties evaluation showed that water extract have the highest percentage of bioactive compounds (24.11%) followed by ethanol (22.77%), methanol (19.2%) and hexane (11.61%). In both of antioxidant and antibacterial activities evaluations, the trend of detection was hexane < ethanol < water < methanol for the detection of antioxidant activities and detection of zone of inhibition, respectively.
