黑果枸杞体外模拟消化及抗氧化研究
In vitro simulation of digestion and antioxidant properties of Lycium ruthenicum
目的 以黑果枸杞为研究对象,对其进行体外模拟胃肠消化,探讨消化过程中黑果枸杞活性成分和抗氧化性的变化。 方法 采用紫外分光度计对黑果枸杞花色苷、黄酮、多酚含量和抗氧化指标DPPH、ABTS自由基清除率进行测定。 结果 在体外模拟胃、肠消化3 h的过程中,黑果枸杞花色苷分别降低了1.971 mg/g和8.315 mg/g;体外消化2 h时多酚含量分别上升了4.431 mg/g和1.480 mg/g;胃消化使黄酮含量下降5.842 mg/g,而肠消化2 h黄酮含量达到最高值6.004 mg/g。胃、肠体外模拟消化阶段,DPPH自由基清除率分别下降了16.48%和4.99%,ABTS自由基清除率分别下降了8.64%和12.1%。 结论 花色苷、黄酮、多酚含量的变化对抗氧化性有一定作用。
Objective The study aimed to investigate the changes in active ingredients and antioxidant properties during the digestion process of Lycium ruthenicum by simulating in vitro gastrointestinal digestion. Method The content of anthocyanosides,flavonoids,polyphenols,the antioxidant indexes DPPH and ABTS free radical scavenging rate were measured by ultraviolet spectrophotometer. Result During the process of in vitro simulation of gastrointestinal digestion lasting for 3 hours,the anthocyanin content in L.ruthenicum decreased by 1.971 mg/g and 8.315 mg/g,respectively;the content of polyphenols increased by 4.431 mg/g and 1.480 mg/g respectively at 2 h after in vitro digestion; gastrointestinal digestion decreased flavonoids content by 5.842 mg/g;the content of flavonoids decreased by 5.842 mg/g after gastric digestion,and reached the highest value of 6.004 mg/g after intestinal digestion for 2 hours.The scavenging rate of DPPH and ABTS decreased by 16.48% and 4.99%,8.64% and 12.1%,respectively during the process of in vitro simulation of gastrointestinal digestion. Conclusion The changes of anthocyanin, flavonoid and polyphenol contents had a certain effect on antioxidation.
