Total phenol and flavonoid content, antioxidant and cytotoxicity assessment of Algerian Launaea glomerata (Cass.) Hook.f. extracts

El-Oued province (southeast Algeria), is located in a medicinal plant-rich area; Launaea glomerata (Cass.) Hook. f. is one among them which is a perennial herb spread widely in the arid regions of the Mediterranean Sea. The selection of the studied plant corresponds perfectly to the scientific needs due two reasons, firstly because these samples are used by the Algerian population as herbal remedies for primary health care, secondly, for the lack of published data on it. The aim of this investigation is to provide new data on quantities of phenols, which were estimated at 25.81 mg GAE/g extract and flavonoids (49.13 mg RE/g extract), and the determination of antioxidant activities by three ways (DPPH, CAT, ABTS), the results of IC50 equals to 98.07 mg TE/g extract for DPPH• and 286.5 mg eq. AG/g for ABTS assays, noted that the best inhibition was by the ABTS root. We also conducted a test for the inhibitory ability of extract against cancer cells tested on both human hepatocellular carcinoma (HePG2) and colon cells (HCT116), the results were negative. The data obtained in this work can be useful for the pharmaceutical industry, also used in the Algerian medicinal herbs database.  DOI: http://dx.doi.org/10.5281/zenodo.442970

Lobularia libyca: phytochemical profiling, antioxidant and antimicrobial activity using in vitro and In silico studies

Lobularia libyca (L. libyca) is a traditional plant that is popular for its richness in phenolic compounds and flavonoids. The aim of this study was to comprehensively investigate the phytochemical profile by liquid chromatography, electrospray ionization and tandem mass spectrometry (LC-ESI-MS), the mineral contents and the biological properties of L. libyca methanol extract. L. libyca contains significant amounts of phenolic compounds and flavonoids. Thirteen compounds classified as flavonoids were identified. L. libyca is rich in nutrients such as Na, Fe and Ca. Moreover, the methanol extract of L. libyca showed significant antioxidant activity without cytotoxic activity on HCT116 cells (human colon cancer cell line) and HepG2 cells (human hepatoma), showing an inhibition zone of 13 mm in diameter. In silico studies showed that decanoic acid ethyl ester exhibited the best fit in β-lactamase and DNA gyrase active sites; meanwhile, oleic acid showed the best fit in reductase binding sites. Thus, it can be concluded that L. libyca can serve as a beneficial nutraceutical agent, owing to its significant antioxidant and antibacterial potential and due to its richness in iron, calcium and potassium, which are essential for maintaining a healthy lifestyle
