Determination of the effect of different drying methods on secondary metabolites of Lavandula pedunculata (Mill.) Cav. subsp. cariensis (Boiss.) Upson & S. Andrews by LC-HRMS

Abstract

This study shows the effects of different drying methods on the secondary metabolite composition of Lavandula pedunculata (Mill.) Cav. subsp. cariensis (Boiss.) Upson & S. Andrews were evaluated. MeOH extracts of dried plants which were dried with different techniques-sun, shade, oven and microwave- were analyzed by by LC-HRMS method. The findings revealed that the amounts of phenolic substances decreased after drying compared to the fresh sample; moreover, rosmarinic acid and syringic acid were found in quite high amounts at L. pedunculata subsp. cariensis.
