A review on in vivo and in vitro methods used for screening antioxidant activity

ABSTRACT

Antioxidant activity has been assessed in many ways. The combination of all approaches with the many test methods available explains the large variety of ways in which results of antioxidant testing are reported. Several test procedures may be required to evaluate such antioxidant activities. The methods are broadly classified as in vitro and in vivo methods. And those are described and discussed below in this review article. As per this review there are 6 in vitro methods and 5in vivo methods that are being used for the evaluation of antioxidant activity of the sample of interest. DPPH method was found to be used mostly for the in vitro antioxidant activity evaluation purpose while LPO was found as mostly used in vivo antioxidant assay.
