Comparative Exploration of Medicinal and Photosynthetic Occurrences of Coriandrum sativum, Menthapiperita and Spinacia oleracea

Abstract

Abstract
Plants form a large group of valuable materials like medicines, alkaloids, flavonoids, carotenes, and chlorophylls. To evaluate these activities leaves of three plant samples i.e., Coriandrum sativum, Mentha piperita and Spinacia oleracea were used in this study and two organic solvents i.e., acetone and ethanol were used to extract the antibacterials and antioxidants from plant samples. Total flavonoid content, total phenolic content and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging methods were used to determine antioxidant activities of these plants. Highest value of DPPH inhibition were found in Coriandrum sativum i.e., 68.00% followed by Mentha piperita i.e., 61.62%. Bacillus pumilus, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus were used to determine the antibacterial activity of plants with agar well diffusion assay. The total flavonoid content and chlorophyll contents were found maximum in Spinacia oleracea i.e., 24 mg QE/g and (chl a) 0.892 mg/g and (chl b) 0.779 mg/g dry weight, respectively while total phenolic content and carotene content was found maximum in Mentha piperita i.e., 75 mg CE/g and 0.309 mg/g dry weight of plant sample.
