Changes of Main Nutrients and Antioxidant Activities of Leaves of Apocynum venetum L.after Fermentation
摘要
Abstract
The leaves of Apocynum venetum L.was fermented with Aspergillus niger.The fermented samples were subjected to freeze-drying treatment,and the contents of amino acids,proteins,and reduc-ing sugars were determined.The changes in major phenolic substances contents and their antioxidant ac-tivity were analyzed.The results showed that there were no significant changes in the contents of amino acids and proteins during the first 6 d of fermentation.However,the content of crude protein content in-creased while amino acid content decreased at the 12th day.Reducing sugar consistently decreased throughout the fermentation process.After 6 days of fermentation,the total amount of major phenolic sub-stances significantly increased(p＜0.05),showing an 8.58％increase compared with the non-fermented state.The contents of chlorogenic acid,rutin,and astragalin showed a trend of first increasing and then decreasing during fermentation,whereas caffeine acid and quercetin continued to increase.The DPPH and ABTS+radical scavenging rate of the fermented samples was 18.90％and 14.78％higher than that of the unfermented samples,respectively after 6 d fermentation.Overall,6 d fermentation had no significant effect on the total protein and amino acid content of A.venetum but significantly enhanced the total con-tent of major phenolic substances and antioxidant capacity.关键词
