Phenolic Compounds and Health-Promoting Effects of Thymus praecox subsp. grossheimii

Abstract

Thymus genus belonging to the Lamiaceae family have been used in traditional medicine for years in the treatment of various illness such as stomach, fever, and flu. The purpose of this study is to assess the phenolic content and quantity in Thymus praecox subsp. grossheimii extract. Thymus praecox subsp. grossheimii (Ronniger) was collected from Tokat, Turkey and dried at shade. Quantitative analysis of the methanol extracts was executed by High-performance liquid chromatography with diode-array detection (HPLC-DAD). The results showed, coumarin was found as a major compound (18.3 mg/g extract). Neohesperidin (7.10 mg/g extract), rutin (2.36 mg/g extract), resveratrol (2.24 mg/g extract), catechin (1.20 mg/g extract), vanillic acid (0.27 mg/g extract), gallic acid (0.23 mg/g extract), quercetin (0.21 mg/g extract), t-cinnamic acid (0.16 mg/g extract), o-coumaric acid (0.11 mg/g extract) were found in methanol extract of Thymus praecox subsp. grossheimii. The medicinal importance of this plant may be due to the determined bioactive compound contents.
