Wild Thyme (Thymus serpyllum) is perennial, herbaceous plant of Lamiaceae family. It has
aromatic, antioxidant, antiseptic, anthelmintic, repelent, antirheumatic, expectorant,
antispasmotic, carminative, sedative and diuretic properties. Optimization of the extraction by
maceration of T. serpyllum was carried out through varying degrees of fragmentation (0.3, 0.7
and 1.5) and the type of solvent (water, ethanol and mixtures of those in weight ratio 50:50 and
70:30). Extraction efficiency was expressed via total polyphenols content and antioxidant
activity. The highest total polyphenols content and antioxidant activity were recorded in 50%
ethanolic extract, with a degree of fragmentation of 0.3, 921,51 mg GA/g DW and 0,538 mM
Trolox/g DW, respectively. No significant differences were observed between total polyphenols
and antioxidant activity in water and in 70% ethanolic extracts. The lowest total polyphenols
content and antioxidant activity were obtained in 96% ethanolic ex...tract (70.73 mg GA/g DW and
0,142 mM Trolox/g DW, respectively).
