The aim of the present study was to determine SPF values and antioxidant capacity of Tanacetum parthenium (Asteraceae), parthenolide and parthenolide free T. parthenium.
Products, with high SPF values protect the skin from harmful UV rays (1). SPF were determined according to Mansur et al (2). 100 and 200 μg/mL concentrations of samples were scanned at wavelength 290-320 nm and three replicates were made and results were obtained between 0.88-2.34 (200 μg/mL).
Products with antioxidant capacity delay skin aging. In this study, antioxidant capacities of methanolic extracts prepared at 25, 50, 100, 250 and 500 μg/mL concentrations of parthenolide -containing or -free Tanacetum parthenium and parthenolide were tested with 4 different methods. The most effective concentration was found at 500 μg/mL. Values are given in the table below.
| Tanacetum parthenium | Parthenolide | Parthenolide free T. parthenium | |
| DPPH | 87.8% | 8.12% | 80.33% |
| ABTS | 85.5% | 21.99% | 80.95% |
| NO | 37.26% | 36.64% | 39.75% |
| Phosphomolibdate | 88.91% | 32.37% | 35.92% |
As a result, it was determined that, removal of parthenolite from Tanacetum parthenium did not change antioxidant capacity and the unprocessed extract was found to be most effective. SPF results of all tested materials have not been found significant.
