DPPH is a free radical with good stability. It is generally purple. When there is a scavenger, the single electron pair in DPPH makes its color lighter, and the absorbance value becomes smaller. If the test substance can remove it well, the importance can reduce the effective concentration of oxygen free radicals and alkyl free radicals. Therefore, the clearance rate of DPPH is one of the indicators for natural antioxidant screening. In contrast, the clearance rate of purified raspberry flavonoids on DPPH is higher than that of Vc.
Hydroxyl radicals are the most active in free radicals. It quickly reacts with some molecular groups. Therefore, eliminating hydroxyl groups is one of the more effective means for the body to resist diseases. The scavenging effect of Pure Raspberry Extract on hydroxyl groups increases with the concentration of active ingredients.
Antioxidant studies of raspberry extracts in vitro show that raspberry flavonoids have varying degrees of scavenging effects on hydroxyl groups, H2O2, and DPPH in vitro. Qyherb's Pure Raspberry Extract has a high content of active ingredients. And we can provide you with a third-party test report to ensure product quality.
