Bioassay-Guided Fractionation of Anti-Inflammatory Alkaloids from Tinospora cordifolia - Issue cover

Abstract

Tinospora cordifolia (Willd.) Miers is a common medicinal plant used in Ayurvedic medicine from which we have previously shown promising anti-inflammatory properties can be attributed to alkaloids in the plant. The objective of our study was to isolate and characterize anti-inflammatory alkaloids from this plant through guided bioassay fractionation and isolation of the methanolic stem extract. Methanolic extract was fractionated into hexane, chloroform, ethyl acetate, and aqueous extracts sequentially. We evaluated the extracts for inhibition of nitric oxide (NO) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The best extracts underwent chromatographic purifications and active compounds were identified using NMR and LC-MS. Two alkaloids decreased NO formation with an IC₅₀ of 18.3 µg/mL and 21.6 µg/mL with little if any cytotoxic activity. These data support the therapeutic application of selected T. cordifolia alkaloids as natural anti-inflammatory compounds and warrant pharmacological development.

Comparative Phytochemical Analysis of Green Vs. Black Tea Leaves

Tea is an engrossing beverage based on Camellia sinensis which has grown to be one of the most popular drinks with birds of a feather, the most used type being the green and black tea. Even though the two products are derived from the same plant, their differences in the way they are treated after harvesting them substantially change their phytochemical profiles and their implications on health. The importance of the study was to compare the phytochemical compounds as well as antioxidant action of the tea leaf green and black varieties to form a bias-free comparison by utilizing standard laboratory methods. The presence of essential phytochemicals like phenols, flavonoids, and alkaloids was identified through qualitative screening of the two samples. Green tea had significantly higher values of total phenolic content (TPC), total flavonoid content (TFC), and as well as the antioxidant activity (by using a DPPH assay). Green tea had a mean TPC, TFC, and antioxidant activity was 98.4 mg/g, 85.6 mg/g, and 91.7 % respectively as compared to 76.3 mg/g, 69.5 mg/g, and 783 % in the case of black tea. The differences were significant as established by statistical analysis under the independent samples t-tests (p

Exploring Antioxidant and Anticancer Activities of Polyphenolic Compounds from Indigenous Herbs

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

In-Vitro Anticancer Activity of Plant-Derived Terpenoids Against Breast Cancer Cell Lines

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.
