Abstract

Background: Berberis commutata Eichler is a berry that grows in the Peruvian Andes and has been consumed in the Andes of South America since ancient times. The edible fruits have an intense purple color and are rich in anthocyanins and phenolic compounds that are available from February until May each year. The color of the fruits is a soft purple dye for natural fibers, and many birds use them as food. Objective: This study quantified the total phenolic, monomeric anthocyanin content and antioxidant activity of Berberis commutata Eichler berries. Methods: The total phenolic content was determined by the Folin-Ciocalteu colorimetric assay. Monomeric anthocyanin content was determined by the pH difference method, and the antioxidant activity was measured using the Brand-Williams method. Results: The total phenolic content was 7,490 ± 0.85 mg GAE/100g, and the monomeric anthocyanin content was 70 ± 0.03 mg/100g. The antioxidant activity of the berries showed a tendency to increase with B. commutata extract concentration; an EC50 of 0.91 mg/mL was calculated, indicating a high antioxidant power. Conclusion: Our results showed that B. commutata E. has both high total phenolic content and monomeric anthocyanins comparable to other superfruits and increased antioxidant activity, which means that it is possible to use this berberis species as a functional food.

换向小檗果实总酚、单体花青素含量及抗氧化活性研究

背景:小檗是一种生长在秘鲁安第斯山脉的浆果，自古以来就在南美洲的安第斯山脉被食用。这种可食用的果实呈深紫色，富含花青素和酚类化合物，每年2月至5月上市。果实的颜色是天然纤维的软紫色染料，许多鸟类把它们当作食物。目的:定量测定换向小檗果实中总酚、单体花青素含量及抗氧化活性。方法:采用福林比色法测定总酚含量。采用pH差法测定单体花青素含量，采用Brand-Williams法测定抗氧化活性。结果:总酚含量为7490±0.85 mg GAE/100g，单体花青素含量为70±0.03 mg/100g。随着换向草提取物浓度的增加，其抗氧化活性呈增加趋势;EC50为0.91 mg/mL，具有较高的抗氧化能力。结论:与其他超级水果相比，换向草具有较高的总酚含量和单体花青素含量，且抗氧化活性较强，可作为功能性食品加以利用。
