Introduction and aim. Several medicinal plants from India have been reported to be effective against human pathogens, but comprehensive comparative studies are scarce. The aim of this study has been to evaluate and compare the antimicrobial activity, phytochemical composition, and stability at different temperatures and pH of ethanolic extracts of eighteen Indian medicinal plants which are prevalent in North-east India and thrive abundantly. Material and methods. These plants included Syzygium cumini, Cannabis sativa, Camellia sinensis, Murraya koenigii, Alstonia scholaris, Terminalia chebula, Flemingia strobilifera, Azadirachta indica, Prunus persica, Euphorbia thymifolia, Averrhoa carambola, Paderia foetida, Psidium guajava, Spondias pinnata, Garcinia cowa, Litsea cubeba, Micania macrantha, and Phlogocanthus thyrsiflorus. Their potent medicinal properties made them the ideal choice for this study which included the use of agar well diffusion method and phytochemical analysis. Results. Agar well diffusion has been used to test their antibacterial activity, which demonstrated higher antibacterial activity of G. cowa extract against Vibrio cholerae and Staphylococcus aureus, whereas S. pinnata extract was most effective against V. cholerae and Enterococcus faecium. Conclusion. Phytochemical analysis revealed the presence of tannins, alkaloids, saponins, glycosides, steroids, terpenoids, flavonoids, and phenols. The antimicrobial activity of these plant extracts remained stable at higher temperatures and varying pH levels.

Introduction and aim. Wound healing is a biological process that aims to restore tissue integrity and function. Despite medical advances, wound management remains challenging. Traditional medicinal preparations, like Apamarga ksharodaka (AK), offer promising therapeutic potential due to their phytochemical richness. This study evaluated wound healing and antimicrobial activity of AK. This study aimed to validate the traditional claim of AK’s wound healing potential using an excision wound model. Material and methods. An excision wound model was created using 24 male Wistar rats. A positive control group applied 5% w/w povidone-iodine (PI) ointment. Wound contraction (WC), epithelialization period (ET), wound closure day, and histopathology were assessed. Antibacterial activity was evaluated against Escherichia coli, Streptococcus aureus, Pseudomonas aeruginosa, and Acinetobacter baumannii. Results. AK showed slightly better wound healing than PI ointment, with significant results in WC rate, wound closure, and ET. Histopathology revealed normal skin and organ architecture. The minimum MIC was 6.25 mg/ml against Pseudomonas aeruginosa with a maximum inhibition zone of 15 mm. Conclusion. AK is safe and effective for wound healing.
