AI Article Synopsis
- Leaves of Sorbus L. have been traditionally used for medicinal purposes, with their main pharmacological effects linked to phenolic compounds.
- In a study of multiple Sorbus species, 24 chemical constituents were identified using advanced chromatography techniques, highlighting their potential health benefits.
- The antioxidant activity varied among species, with S. commixta, S. discolor, and S. gracilis showing the highest levels of activity, primarily due to the presence of neochlorogenic and chlorogenic acids.
Article Abstract
Leaves of Sorbus L. have been used in various traditional medicine systems. Phenolic compounds determine the main pharmacological effects of Sorbus L. In this study, phytochemical and antioxidant profiles of Sorbus anglica, Sorbus aria, Sorbus arranensis, Sorbus aucuparia, Sorbus austriaca, Sorbus caucasica, Sorbus commixta, Sorbus discolor, Sorbus gracilis, Sorbus hostii, Sorbus semi-incisa and Sorbus tianschanica were determined. Twenty four constituents were identified in Sorbus L. species using ultra high performance liquid chromatography coupled to quadruple and time-of-flight mass spectrometers. Post-column FRAP assay identified compounds with reducing activity and revealed significantly greatest total antioxidant activity of 175.30 μmol TE/g DW, 169.20 μmol TE/g DW and 148.11 μmol TE/g DW in S. commixta, S. discolor and S. gracilis leaf samples, respectively, with neochlorogenic and chlorogenic acids being most significant contributors. Characteristic fingerprints of phytochemical and antioxidant profiles could be applied for the quality evaluation of various raw materials of Sorbus L. species.
