Physicochemical Contents, Antioxidant Activities, and Acute Toxicity Assessment of Selenium-Enriched Chinese Kale (Brassica oleracea var. alboglabra L.) Seedlings

Table 2

Antioxidant capacities after passing gastrointestinal system simulation of regular Chinese kale seedling (R-KS) and Se-enriched Chinese kale seedling (Se-KS).

Method	Sample
	R-KS	Se-KS
IC50 DPPH (mg/mL)	0.79 ± 0.00^a	0.74 ± 0.01^b
IC50 ABTS (mg/mL)	0.58 ± 0.03^a	0.45 ± 0.03^b
FRAP (mgTE/gDW)	18.8 ± 0.2^a	15.3 ± 0.4^b

The data are expressed as mean ± SD (n = 3). The different lowercase letters indicate significant difference between rows at . DPPH = 2,2-diphenyl-1-picrylhydrazyl; ABTS = 2,2-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid), and FRAP = Ferric reducing antioxidant power.
