Vasaka or Adhatoda vasica (L.) Nees is a well-known plant medication in Ayurvedic and Unani medicine. Cough, whooping cough, cold, and clinging phlegm in the mouth, throat, chest, or breast have been traditionally treated using Adhatoda vasica nees. The present study aimed to evaluate Adhatoda vasica's phytochemical analysis and antimicrobial activity. The preliminary phytochemical screening of alkaloids, steroids, saponins, phenols, and terpenoid yielded positive results. The antibacterial activity of ethanol and leaf extracts of Adhatoda vasica was investigated in this study. Based on the data presented herein, the largest zone of inhibition was found to be against Pseudomonas aeruginosa. The antifungal activity of Aspergillus clavatus was proven to have the maximum zone of inhibition. As a result, the current method may be effective in identifying new bioactive compound for the development of novel medications. Thus, it may be used as a strong antimicrobial agent against Pseudomonas aeruginosa pathogens.
Phytochemical Screening and Antimicrobial Activity of Mentha Arvensis L. [Pudina]: A Medicinal Plant

Mentha arvensis is an essential aromatic, energizer restorative, and medicinal plant in the mint family Lamiaceae. Mentha arvensis is found in rugged areas or cold climates of India. Herein, we studied the presence of different dynamic metabolites like- Flavonoids, Saponins, Tannins, terpenoids, steroids, Carb, anthraquinones, Heart glycosides, and alkaloid. In the given study, the phytochemical and antimicrobial action of leaves concentrates on pudina (Mentha arvensis L.). The broth dilution method has been used to check the antimicrobial activity of Mentha arvensis. In vitro antimicrobial movement was studied against pathogenic microbes such as Escherichia coli, Staphylococcus aureus, Streptococcus Pyogenes, Pseudomonas aeruginosa, Candida albicans, Aspergillus Niger, Aspergillus clavatus by agar well dispersion method. When used on bacterial colonies and fungal colonies, the separated extract showed the maximum zone of inhibition against Staphylococcus aureus, Escherichia coli, Streptococcus Pyogenes, Pseudomonas aeruginosa, Candida albicans, Aspergillus Niger, Aspergillus clavatus over the control. The maximum zone of inhibition was found in Methanolic extracts against Pseudomonas aeruginosa and Aspergillus clavatus over the control. Thus, the present approach can be useful to find new bioactive segments to improve new drugs. Our findings showed that the Mentha arvensis plant gives 25- 100 MIC (ug/ml) to inhibit the growth of the mentioned microorganisms. Thus, it can be used as a strong antimicrobial agent against pathogens, mainly Aspergillus Clavatus.
