Figure 4: Estimation of plasma peak concentration (Cmax, ng/ml) of α-tocopherol of various doses: The doses of 125 mg, 250 mg, 500 mg/d of DeltaGold-based δ-tocotrienol were administered to well fed healthy participants (11 subjects/dose). The blood samples were collected in ethylene diamine tetra acetic acid (EDTA) glazed tubes at pre-dose (0 h) to post-dose 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, 10 h intervals of each subject. The plasma samples were harvested and processed to carry out normal phase HPLC analyses as described in Material and Method section. Values are means ± standard deviation (n = 11/dose). Values are significant different at P<0.01 from each other.
