Phytochemicals from <i>Phillyrea latifolia</i> L. leaves and fruit extracted with various solvents: Their identification and quantification by LC-MS and antihyperglycemic effects

ABSTRACT Phillyrea latifolia L. is a type of shrubland, which widely known as mock privet, and belongs to the Oleaceae family. The objective this study was compare assess phytochemical composition, antioxidant antidiabetic activities ethyl acetate, methanol aqueous extracts fruit leaves P. Phenolics were analysed by detecting individual bioactive compounds using an LCMS-2020 quadrupole mass spectrometer calculating total phenolic content (TPC). For first time, both determined DPPH radical scavenging. extract indicated have higher than acetate extracts. constituents within different for detected luteolin-7-O-glucoside in (854 μg · g –1 1,098 ), (1,241 2,136.43 ) (509 898.23 extracts, respectively. Extractions demonstrated stronger inhibitory activity against human salivary α-amylase parts privet. Similarly, extraction from privet significantly better respectively, inhibition α-glucosidase activity. This indicates that may use potential source natural biomolecules promote healthy activities.
