Antioxidant and Antiproliferative Activities of the Essential Oils from Thymbra capitata and Thymus Species Grown in Portugal

Figure 3

Antiproliferative activity of the essential oils on THP-1 cell line with 96 h exposure. The mean absorbance values for the negative control (DMSO treated cells) were standardized as 100% absorbance (i.e., no growth inhibition) and results were displayed as absorbance (% of control) versus essential oil concentration.
