Cytotoxicity Assessment of Six Different Extracts of Abelia triflora leaves on A-549 Human Lung Adenocarcinoma Cells

Abstract

The present investigation was designed to assess the anticancer activity of six different leaf extracts (ethyl acetate, methanol, chloroform, petroleum ether, n-butanol, and water soluble) of Abelia triflora on A-549 human lung adenocarcinoma epithelial cells. A-549 cells were exposed to 10-1000 μg/ml concentrations of the leaf extracts of A. triflorafor 24 h and then percentage cell viability was assessed by 3-(4,5-dimethylthiazol-2yl)-2,5-biphenyl tetrazolium bromide (MTT) assay. The results showed that leaf extracts of A. triflora significantly reduced the viability of A-549 cells in a concentration-dependent manner. Decrease was recorded as 31% with ethyl acetate, 36% with methanol, 46% with chloroform, 54% with petroleum ether, 62% with n-butanol, and 63% with water soluble extracts at 1000 μg/ml each. Among the various plant extracts, ethyl acetate extract showed the highest decrease in the percentage cell viability, followed by methanol, chloroform, petroleum ether, n-butanol, and water soluble extracts. Our results demonstrated preliminary screening of anticancer activity of different soluble extracts of A. triflora extracts against A-549 cells, which can be further used for the development of a potential therapeutic anticancer agents.

Free Radical Scavenging and In vitro Cytotoxic Activity of Bugnay (Antidesma bunius) Leaves Extract against A549 Human Lung Adenocarcinoma and HCT-116 Human Colorectal Cancer Cell Lines

“…The cytotoxic activity may be attributed to the phytochemical compounds, namely, saponins, diterpenes, tannic acid, polyphenols, and flavonoids. Flavonoids found in different plant sources showed activity against lung cancer cells (Al-Taweel, et al, 2015). Antitumor properties of flavonoids include decreasing mitochondrial potential, overexpressing Fas and FADD ligands, and promoting DNA fragmentation (Abotaleb, et al, 2019).…”
