Muell and Eucalyptus stricklandii Maiden leaves extracts: HPLC-DAD, GC-MS analysis and in vitro biological activities, combined with the principal component analysis, Application In Synthesis of 124-76-5, the main research area is Eucalyptus brevifolia stricklandii leaf extract HPLC MS biol activitiy.
Natural products always have been relevant for the advancement of new pharmacol. products intended to prevent oxidative stress and many diseases since ancient times. Herein, the chem. composition was investigated via chromatog. anal. of varying polarity solvents (petroleum ether, Et acetate, methanol and distilled water) from Tunisian Eucalyptus brevifolia F.M and Eucalyptus stricklandii M. leaves. In vitro provision of biol. activities through their antioxidant power (ABTS.+), ability to inhibit 15-lipoxygenase (15-LOX), acetylcholinesterase (AChE), xanthine oxidase (XOD), as well as, cytotoxic potency were undertaken. Chem. profiling showed that the methanolic extracts of both species were the richest in total phenolic compounds GC-MS anal. of the two Eucalyptus species revealed that spathulenol, globulol, epiglobulol, and trans-Z-alpha-bisabolene-epoxide were the main volatile compounds detected in the different extracts In addition, the derivatization procedure allowed the identification of ethylene glycol, and D-fructofuranose as very abundant mols. The HPLC-DAD has enabled the identification of eight new mols. among them icariin (1.1 mg/g dr), and 5-hydroxy-3prime-methoxyflavone (7.5 mg/g dr) in the E. stricklandii MeOH and EtOAc extracts Aqueous E. brevifolia extract possessed the highest anti-AChE with an IC50 (10 mug/mL). Whereas, the MeOH E. stricklandii extract possessed the highest anti 15-LOX with an IC50 (9.7 mug/mL), as well as, the most important percentage of XOD inhibition 51.1%. All extracts revealed an antiproliferative potency against human cancer cell lines HCT-116, MCF-7 and OVCAR, with an inhibition percentage up to 96%. Taken together, both Eucalyptus species have a broad range of potential applications in several fields, such pharmaceutical, medical and food industries as nutraceutical supplements.
