The present study makes a recommendation for estimating the ABTS*+ capacity accurately and reasonably. azino - di ( 3 - ethylbenzthiazoline - 6 - sulfonate ) ( ABTS ). However, full and accurate evaluation of antioxidant reactivity rather than capacity requires recording ABTS*+ loss continuously during the whole reaction period.

ABTS*+ assay could be measured within 2-10 min to obtain a rough result, which was mostly 6 min in the literature. It is an analog of a benzene ring in which one or more of the carbon atoms has been replaced by a nitrogen atom, and thus is also called an azabenzene. When using different pre-diluting solvents, different detection wavelengths should be selected. The results showed that the solvent effects were very significant. To develop an effective and universal method for estimating the ABTS*+ capacity accurately and reasonably, five pre-dilution solvents and different reaction times were investigated in ABTS*+ assays of five typical antioxidants. azino-di(3-ethylbenzothiazoline sulfonate) ACE: angiotensin-converting.

The existing methods for ABTS*+ radical-scavenging activity assays are diverse in pre-diluting solvents and reaction time, which lead to errors in the TAC estimations. 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation (ABTS*+) is a stable free radical frequently used for estimating the total antioxidant capacity (TAC) of natural products.
