Proposed method was successfully applied to the determination of phenolic compounds in an olive leaf extract and 24 compounds were analyzed quantitatively. Olive biophenols were extracted from olive leaves by using microwave-assisted extraction with acceptable recovery values between 78.1 and 108.7%. Good linearities were obtained with correlation coefficients over 0.9916 from calibration curves of the phenolic compounds. The limits of quantifications were from 0.14 to 3.2 μgg-1. Intra-day and inter-day precision studies indicated that the proposed method was repeatable. As a result, it was confirmed that the proposed method was highly reliable for determination of the phenolic species in olive leaf extracts. © The Author(s) 2017.EnglishAll Open Access; Bronze Open AccessChromatography, LiquidLinear ModelsOleaPhenolsPlant ExtractsPlant LeavesReproducibility of ResultsSensitivity and SpecificitySpectrometry, Mass, Electrospray IonizationTandem Mass Spectrometryphenol derivativeplant extractchemistryelectrospray mass spectrometryliquid chromatographyolive treeplant leafproceduresreproducibilitysensitivity and specificitystatistical modeltandem mass spectrometryDevelopment and validation of an analytical methodology based on liquid chromatography-electrospray tandem mass spectrometry for the simultaneous determination of phenolic compounds in olive leaf extractArticle10.1093/chromsci/bmy003
