Title: Pharmacognostical evaluation, qualitative analysis of phytochemicals and antimicrobial effects of different extracts of Acalypha fruticosa leaves
Dr. Jai Shanker Pillai H P currently positioned as Faculty of Public Health at St Theresa International College, Thailand since 2017. He was an Assistant Professor in the department of Life Sciences, Kristu Jayanti College, Bangalore University, Karnataka, India. His doctorate was in Microbiology from Gulbarga University, Karnataka, India in 2016. He has several publications of research articles, Book chapters and Books. He is a Life member of professional bodies and editorial board member for many of the life science research journals. He also has several research awards and recognition to his credit. His research interests are Environmental Microbiology, Agricultural Microbiology, Antimicrobial properties of medicinal plants and Medical Microbiology. He has his expertise in Bioremediation and Biodegradation of environmental xenobiotic pollutants through microorganisms. His innovative ideas and novel approaches in exploring microorganisms for plethora of environmental applications open up a new rational vent for environmental conservation, protection and sustainability.
Recently the acceptance of traditional medicine as an alternative source for human health care and the improvement of microbial resistance to the available antibiotics have reaffirmed the need to probe the antimicrobial activity of herbal plants. Acalypha fruticosa is one such plant commonly known as “Chinnichedi” and “Birch leaved acalypha” is a shrub belonging to thefamily of euphorbiaceae.The Paliyar and Irula tribes in Western Ghats of South India used the leaves and roots of A. fruticosa to treat skin diseases, wounds,stomach ache and poisonous bites.
Nevertheless until today, there were no reports to justify its ethnobotanical claim. The objectives of our study were to evaluate the pharmacognostic characters, qualitative phytochemical screening and antimicrobial activity of A. fruticosa.
Material and methods:
The qualitative phytochemical analysis was performed by standard procedure. The antimicrobial activity of selected medicinal plant was carried out by using disk diffusion method. Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and minimum fungicidal concentration (MFC) was tested by using tube dilution method.
Results & Conclusion:
The results of the qualitative phytochemical analysis and fluorescence analysis confirm that this plant is the plentiful source of phytoconstituents. The antimicrobial activity of selected medicinal plants A.fruticosa explicate that it has an effective antimicrobial activity. In bacteria E.coli showed more sensitivity against acetone extract (21 ± 0.3 mm). In fungi the T.simii showed more sensitivity against chloroform extract (22 ± 0.3 mm). Moreover the acetone extract had more antimicrobial activity than other extracts. In conclusion, we recommend that the plant Acalypha fruticosa apprised here can be used as promising antimicrobial agent in infectious disease treatment.
