摘要：
In this paper, the process of acid extracting pectin from Guangyechu white bast and subsequent ammonium sulfate pulping was optimized by condition test. Under optimal conditions, the pectin yield was 3.99%, the screened pulp yield was 52.61%, KMnO4 value was 9.84 and whiteness was 51.7%ISO. And chemical compositions of Guangyechu white bast in each treatment stage were compared and analyzed.
