Sun Protection Factor (SPF) and antioxidant capacity of Lavandula angustifolia L.

The essential oil from lavender is mostly used for cosmetic purposes. However, it is known that in recent years, Lavandula angustifolia L. (Lamiaceae) has been researched on the skin rejuvenating properties (1).

In this study was to determine SPF values and antioxidant capacity of methanolic extract from Lavandula angustifolia, linalool and linalool free L. officinalis.

SPF were determined according to Mansur et al (2). 100 and 200 µg/mL concentrations of samples were scanned at wavelength 290 – 320nm and three replicates were made. SPF values (0.62 – 1.37) of Lavandula officinalis, linalool and linalool free L. officinalis were found considerably low.

Antioxidant capacity tests were performed at 5 different (25, 50, 100, 250 and 500 µg/mL) concentrations. The best results were obtained with 500 µg/mL.

The results of 500 µg/mL were given in the table below.

NO	37.57%	38.81%	36.33%
Phosphomolybdate	92.01%	37.25%	34.81%
