Table 1.

Antioxidant activity (EC₅₀ values in g L⁻¹) of leaf extracts of O. basilicum at the end of the light treatment (T_S0) and after seven days of storage (T_S7) from plants cultivated under control (white light) and supplemental UV-B radiation.

Light Treatments	Moment of Harvesting
Light Treatments	T_S0	T_S7
Control	0.13 ± 0.07 ^b	0.24 ± 0.04 ^a
UV-B	0.16 ± 0.02 ^{a, ns}	0.05 ± 0.009 ^b,***

Mean values ± SD (n = 3). Letters show the comparison between different times (T_S0 vs. T_S7) within the same light treatment. Different letters indicate significant differences between the values (p < 0.05), while asterisks show significant differences between light treatments at the same time of storage (*** p ≤ 0.001); ns = not significant.
