Analysis of phenolic compounds in flowers and leaves of English Lavender (Lavandula angustifolia Mill.) using UPLC-ESI-MS/MS

Abstract

Lavender (Lavandula angustifolia Mill.) is used as raw material in various industries such as pharmaceuticals, cosmetics, etc. This study aims to analyze the phenolic compounds and proportions of medicinal lavender (Lavandula angustifolia) in its leaves and flowers and determine the levels of these compounds. A total of 9 phenolic compounds were identified in the leaf and flower samples obtained from the lavenders grown in Ula (Mugla) during the flowering period. Major phenolic compounds detected in leaf and flower samples of Lavender (Lavandula angustifolia Mill.) during the flowering period were protocatechuic acid (189.38 μg/kg), 3,4-dihydroxybenzaldehyde (168.97 μg/kg), and 4-vanillic acid (77.54 μg/kg).
