Table 3.

Lipophilic profile (g kg⁻¹ DW) of Olea europaea leaves (Giarraffa variety) under control (C) and UV-B conditions sampled at the 2nd (T2), 4th (T4), 6th (T6), and 8th (T8) week after the onset of stress. Values are mean ± standard deviation (n = 3). Rt—Retention time. ANOVA showed that most of chemical components were significantly affected by the main factors and their interactions.
