The present study was aimed to investigate the phytochemical screening and antimicrobial activities of Calotropis gigantea leaf extracts. In addition to these studies we also check the effect of UV light radiation on the anti microbial activity of leaf extract. | Preliminary phytochemical antimicrobial and photochemical study of Calotropis gigantea leaf extract Current Chemistry Letters 9 2020 105 112 Contents lists available at GrowingScience Current Chemistry Letters homepage Preliminary phytochemical antimicrobial and photochemical study of Calotropis gigantea leaf extract Waseem Ahmada a Organic Chemistry Section Department of Chemistry Uttaranchal University Dehradun 248001 India CHRONICLE ABSTRACT Article history Several Plant products have been found to be a part of phytomedicines since time immemorial. Received August 4 2019 These plant products can be derived from barks leaves flowers roots fruits and seeds. It has Received in revised form been found that the light radiation affects the antimicrobial activity of herbal products. The August 30 2019 present study was aimed to investigate the phytochemical screening and antimicrobial Accepted September 27 2019 activities of Calotropis gigantea leaf extracts. In addition to these studies we also check the Available online effect of UV light radiation on the anti microbial activity of leaf extract. Phytochemical September 28 2019 screening revealed the presence of various active phytochemicals in the extracts of aerial part Keywords of Calotropis gigantea. Ethanol chloroform and hexane extract of leaves were tested against Phytochemical Photochemical Clostridium botulinum Proteus vulgaris Escherichia coli and Arthrographis cuboid Antibacterial activity Aspergillus fumigatus Aspergillus niger by the agar disc diffusion method. The antimicrobial Antifungal activity activity of the extracts generally reduces significantly after exposure to the UV radiations. Calotropis gigantea 2020 Growing Science Ltd.
