Antibacterial potency of mid-polar extracts obtained from Malaysian plant Parkia speciosa against human pathogenic bacteria.

Background And Objectives: Plants contain a wide variety of bioactive compounds, which have attracted the interest of researchers in finding novel sources of natural medicine. In the following paper, we aim to evaluate the antibacterial potential of extract fractions associated with Parkia speciosa pods and beans against human pathogenic bacteria.

Methods: Antimicrobial activity was determined with disc diffusion and broth microdilution assays against eight skin colonising microorganisms including Staphylococcus aureus, Staphylococcus epidermidis, Salmonella enterica, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia followed by further fractionation of the pods ethyl acetate fraction by column chromatography along with preparative thin-layer chromatography.

Exploring the Role of Herbal Compounds in Skin Aging: A Systematic Review of Topical Approaches.

Recently, dermatology has increasingly focused on understanding skin aging and exploring novel therapeutic approaches. Despite progress in cosmetic and pharmaceutical research, a significant gap remains in comprehensively understanding the effects and mechanisms of herbal extracts on skin aging. While many studies have examined the bioactivities of herbal compounds in preclinical models, comprehensive human trials have been scarce over the past decade.
