Analysis Of E. Platyloba EE

BCBT: As it can be seen in table 2, E. platyloba EO had a strong activity in maintenance of β-carotene molecules especially in C10 (78.25%), which was higher than ascorbic acid and comparable with BHT. The same concentration of ascorbic acid and BHT were used as standard to compare the values. FRAP: The antioxidant efficiency of the E. platyloba EO using FRAP method was calculated with reference to the reaction formula , given by a Fe+2 solution of known concentration. The same concentration of ascorbic acid and BHT were used as comparison. As it shown in table 3 the oil was stronger than standards to reduce the Fe+3 to Fe+2. ABTS: Table 4 lists the results of ABTS test of E. platyloba DC EO. The ABTS radical scavenging of the oil was dose dependent and increased with increment of the E. platyloba EO concentration. The same concentration of ascorbic acid and BHT were used as comparison.
There are various analytical methods for the evaluation of the antioxidant capacity; spectrometric techniques, electrochemical techniques, biosensors method, and chromatographic methods
The ability of any antioxidants to reduce Fe+3 (TPTZ) complexes (ferric iron) to the intensely blue-colored Fe+2 (TPTZ) complexes (ferrous iron) at acidic pH, is the basis of this method (Bhatt et al., 2012). The E. platyloba EO showed stronger antioxidant activity than ascorbic acid and BHT using FRAP assay in this study. Pirbalouti et al.,(2013) evaluated the antioxidant activity of methanol extracts of Heracleum lasiopetalum Boiss, Kelussia odoratissima Mozaff., and E.platyloba DC. by three assays, including DPPH, FRAP, and TEAC. From all three assays, E. platyloba had the highest antioxidant activity. They showed that FRAP assay increased in the order of BHT ≥ E. platyloba. Different components of E.platyloba EOs explains the dissimilar results of FRAP
