Effects of Consumption of Rooibos (Aspalathus linearis) and a Rooibos-Derived Commercial Supplement on Hepatic Tissue Injury by tert-Butyl Hydroperoxide in Wistar Rats

Table 3

Hepatic antioxidant capacity of rats consuming the rooibos herbal tea and rooibos-derived commercial supplement after tert-butyl hydroperoxide-induced oxidative stress.

Antioxidant activity	Supplement groups
	Fermented rooibos	Unfermented rooibos	Rooibos-derived commercial supplement	Water control
FRAP (µmole AAE/g)	5.36 ± 0.5^a	4.60 ± 0.5^a	5.49 ± 2.2^a	5.01 ± 0.7^a
ORAC (µmole TE/g)	4.55 ± 1.4^a	6.53 ± 2.1^b	6.38 ± 1.2^b	4.00 ± 2.1^a
TEAC (µmole TE/g)	41.3 ± 2.0^a	38.9 ± 2.4^a	41.9 ± 1.3^b	37.4 ± 5.4^a

Values are expressed as mean ± STD of 10 rats per group. Similar letters in rows denote lack of significant difference (P > 0.05), but if letters differ then P < 0.05. TE: trolox equivalents; AAE: ascorbic acid equivalents.
