Antimicrobial Activity

The current work used the carrageenan-induced paw edema model in Wistar rats to determine the anti-inflammatory properties of plant-based substances, namely quercetin (Ficus carica) and curcumin (Curcuma longa). Four groups of 24 rats each were created: Quercetin, Curcumin, Standard Drug (Diclofenac), and Negative Control. The volume of paw edema was measured one, two, three, and four hours after induction. Diclofenac showed the greatest suppression of paw swelling at all time periods, while carrageenan was able to successfully produce inflammation in the control group, according to the results. When compared to the control, both curcumin and quercetin considerably decreased inflammation; however, the difference was not statistically significant, with curcumin being slightly more efficient than quercetin. The trustworthiness of these findings was validated by statistical analysis. According to the study's findings, quercetin and curcumin have strong anti-inflammatory properties and could be useful natural supplements or substitutes for traditional synthetic medications.

Conventional antibiotic treatment of bacterial infections is hampered by prevalent antimicrobial resistance. In this research, the synergistic antibacterial activity of different herbal extracts and cefixime against resistant clinical isolates is tested. The preliminary antibiotic susceptibility and antibacterial activity of the herbal extracts were evaluated using disc diffusion and microbroth dilution. Checkerboard experiments, time-kill kinetics, and protein content assays were used to establish synergy. RP-HPLC phytochemical profiling showed high levels of gallic acid (0.24-19.7 μg/mg), quercetin (1.57-18.44 μg/mg), and cinnamic acid (0.02-5.93 μg/mg) in the extracts. 13/16 Gram-negative and 4/6 Gram-positive clinical isolates were resistant to intermediate or total cefixime. Aqueous plant extracts were non-synergistic, whereas ethanolic and methanolic were synergistic. Time-kill kinetics demonstrated that the synergistic interaction reduced bacterial load by 2–8 and was time- and concentration-dependent. The fractional inhibitory concentration index (FICI) combination therapy inhibited growth and protein content (5–62%) in the bacterial isolates from the antibiotic or extract. The research indicates herbal extracts are potential adjuvants to standard antibiotics in resistant microorganisms.

The antibacterial, anti-inflammatory, and wound-recovery houses of a polyherbal methanolic extract (PHME) made from Argemone mexicana, Datura stramonium, and Plumbago zeylanica are tested in this study. Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa had been the 4 bacterial traces towards which the antibacterial pastime of PHME became assessed in vitro the use of techniques such as broth dilution and agar well diffusion. In assessment to the diverse plant extracts, the consequences indicated that PHME had the bottom minimal inhibitory concentrations (MICs) and the widest zones of inhibition, indicating its higher antibacterial effectiveness. According to the examine, PHME's antibacterial performance became on par with that of the commonplace antibiotic, Ofloxacin, particularly whilst it came to Staphylococcus aureus. The antibacterial pastime of PHME become drastically extra than that of the separate extracts, in line with statistical analysis. These consequences mean that PHME has wonderful healing promise alternatively for traditional antibiotics, with potential makes use of in wound healing and the treatment of bacterial infections. To completely inspect its healing variety and medical utility, greater research is needed.
