Flavour Science: Chapter 116. Season-Dependent Variation in the Essential Oil Composition of Myrrhis odorata L. and Evaluation of Antioxidant Capacity of By-Products

The composition of essential oils isolated by hydrodistillation from sweet cicely (Myrrhis odorata) leaves collected at different growth phases in Lithuania was studied by GC-FID/MS. In total, 38 compounds were identified. In order to valorize hydrodistillation by-products, their antioxidant potential was assessed by DPPH radical scavenging capacity (RSC) assay and measurement of total phenolics (TPC). Depending on extraction solvent (acetone, methanol, ethanol, water), the RSC expressed in extract concentration binding 50% in the reaction present DPPH radicals was 0.11–0.98mg/mL, while the content of TP was 10.78–80.6mg gallic acid in g plant material.
