| Abstract: | The pectin was extracted from sunflower disc with acid extraction method by way of ultrasonic technology,and the content of pectin was determined that the galacturonic acid as reference substance and the carbazole as chromogenic agent.The regression equation is y=0.008x-0.0519 and coefficient of correlation r=0.9999.The average recovery was 99.0%,RSD=2.72%(n=5).The content of pectin was 79.7%,the pectin extraction rate was 8.0%. |
