Are bio active-rich fractions functionally richer?

Extract

[...] (LDL oxidation is not significantly different between low and high PUFA group). In HUVEC mM TRF treatment decreased TBARS by 73% compared with 50% by same concentration of a-tocopherol. Arachidonic acid-induced oxidative stress (conjugated dienes) was reduced to a similar level by 10 mM TRF or 25 mM a-tocopherol. TRF is a more potent antioxidant than a-tocopherol (in vitro) TRF and a-tocopherol were metabolized differently. Tocopherol was the major component detected in plasma in both cases, and it peaked at 6 h ( 13.46 1.68 mg/mL) and at 8 h ( 24.3 5.22 mg/mL) following TRF and a-tocopherol supplementation, respectively.

Imam et al. Through in vitro experimentation, Al-Naqeeb and Ismail (2009) have demonstrated the effects of 2 ppm TQ against 80 ppm of a thymoquinone-rich fraction (TQRF containing 2 ppm TQ) on the expression of cholesterol-related genes (APO A1 and APO B100) in HEPG2 cells. The results indicated that the TQRF is able to favorably regulate cholesterol metabolism through upregulation of the APO A1 gene and downregulation of the APO B100 gene to a significantly greater degree than the same concentration of TQ present in the TQRF when used alone.
