Efficacy evaluation of extracts of brassica juncea and brassica alba seeds as potential antibacterial agent-in vitro study, against pyogenic microbes - streptococcus pyrogens, staphylococcu

Summary of article contents:

The World Health Organization (WHO) reported that about 80% of the world’s population depends primarily on traditional medicine [1] Ayurveda is the science of life, which aims at building a healthy body with a sound mind. During the past few decades, and in recent Covid-19 Pandaemic situations traditional systems of medicines have become a topic of global importance. The number of emerging multidrugresistant microbial strains is continuously increasing and has become one of the most serious threats to the successful treatment of infectious diseases. In this study, the antibacterial potentials of the extracts of water, Petroleum ether, methanol & Chloroform of Brassica juncea & Brassica alba seeds were tested against mentioned pyogenic bacteria. Given reports of Brassica species in the treatment of various infections since the Vedic period & Ayurveda, the seed oil had been investigated for its antimicrobial activity by several research workers. Some herbs from Rakshoghna Gana [2] were screened for their in vitro antimicrobial activity on E.Coli and Staphylococcus Aureus. Hence as a part of further research, Brassica juncea and Brassica alba various extracts and crude oils were evaluated for antibacterial activity against pyogenic bacteria Streptococcus aureus, Staphylococcus aureus and E.Coli by Agar Cup Dilution Technique against standard chemotherapeutic agents, by using 12 antibiotics, sensitivity discs. In vitro study revealed out that crude oil of Brassica juncea and Brassica alba is not potent as standard antimicrobial agents, but water extract and methanol extract possess significant antimicrobial activity in Vitro. Both the extract possesses antimicrobial activity against all 3 pyogenic bacteria and potent as standard 12 antimicrobial drugs. The extracts showed a broad spectrum of antibacterial activity, inhibition zones of bacteria strains ranged from 3-12 mm for Staphylococcus aureus,3-15 mm for Streptococcus pyrogens 5-12 mm for E. coli. The result of the study supports the immense medicinal properties of Brassica juncea which has revealed a significant scope to develop a novel broad spectrum of antibacterial herbal formulation. Again Brassica alba was found superior in antibacterial action as compared to Brassica juncea as its mention in Ayurved Lexicon Bhavprakash Nighantu,[3,4] results substantiate the same. This is further open for research workers to carry out further research work on this project and to see the phagocytic action of the drug, fix the dose of the drug, fractionization of water and methanol extracts by HPTLC separation of active principle as further drug development.
