Abstract

The naringin from the pulp of Citrus grandis'Tomentosa' was extracted using surfactant-microwave extraction method, on the basic of single-factor experiment the extraction technology of naringin from the pulp of Citrus grandis'Tomentosa' were optimized using orthogonal test and its antioxidant activity was evaluated. The results showed that the optimal extraction process parameters for naringin from the pulp of Citrus grandis'Tomentosa' were as follows ：ethanol concentration of 50%, microwave time of 5 minutes, SDS mass fraction of 1.5%, and a solid-liquid ratio of 1∶20 （g/mL）. Under these conditions, the extraction rate of naringin from the pulp of Citrus grandis'Tomentosa' was 10.60%, with an RSD of 1.6%. The naringin from the pulp of Citrus grandis'Tomentosa' showed a strong ability to scavenge DPPH, when the concentration of naringin extracted from the pulp of Citrus grandis'Tomentosa' was ≥ 0.40mg/mL, its ability to scavenging DPPH free radicals was comparable to that of Vc.
