Antioxidant activity

Key anti-inflammatory herbal compounds—curcumin, curcumin analogues, resveratrol, boswellic acids derived from Boswellia serrata, and Tripterygium wilfordii extracts—are reviewed in this study, together with mechanistic in vitro data and translational implications, for the management of rheumatoid arthritis (RA). This research provides a summary of their molecular processes, which include cytokine suppression, NF-κB inhibition, antioxidant action, and immunological modulation, based solely on recent systematic reviews, meta-analyses, preclinical evaluations, and randomized trials. Emerging clinical translation in autoimmune illnesses and osteoarthritis is supported by good molecular evidence for these herbs, especially curcumin, resveratrol, and boswellic acids. Bioavailability, consistent dosage, and long-term safety are still areas where research is lacking in RA. Optimized formulations, high-quality RA-specific clinical studies, and mechanistic validation through in vitro disease models should be the priorities of future research.

One of the leading causes of cancer-related death for women worldwide is breast cancer. Natural substances obtained from therapeutic plants, particularly terpenoids, have garnered considerable interest as potential sources for pharmaceuticals. This study aims to determine which plant-based terpenoids, when tested in vitro against MCF-7 and MDA-MB-231, exhibit anti-cancer properties. Terpenoids were extracted using conventional chromatographic methods, and their identification was confirmed using spectroscopic analysis. We used fluorescence microscopy and flow cytometry to detect apoptotic effects and the MTT assay to measure cytotoxicity. The findings demonstrated that the dose affected the effects of apoptosis induction and cancer cell growth inhibition. The authors of the study believe that terpenoids from plants have a lot of potential as a treatment for breast cancer.

Because people are becoming more interested in plant-based medicines, researchers are looking more closely at the bioactive components in medicinal herbs, especially polyphenols, because they may have antioxidant and anticancer effects. The goal of this study was to look into the antioxidant and anticancer properties of polyphenolic chemicals taken from some native herbs using established in vitro methodologies. We did methanolic and hydroethanolic extractions, then we measured the total phenolic and flavonoid content, the antioxidant activity using the DPPH and ABTS assays, and the cytotoxicity using the MTT assay on the MCF-7 and HeLa cell lines. Herb C had the highest total phenolic (168 mg GAE/g) and flavonoid (96 mg QE/g) content of the samples examined. It also had the strongest antioxidant and anticancer activity, with IC₅₀ values close to those of normal ascorbic acid and a considerable decrease in cell viability. One-way ANOVA statistical analysis showed that the differences that were seen were significant (p
