Abstract: Sunflower is an important oil crop in China. The integrated utilization of sunflower by-products, which include the straw and sunflower plate after harvesting, the shell and meal after extracting sunflower oil, was introduced in this article. With the deeper research on technology and equipment, the more perfect condition of industrialization, the winder application foreground of sunflower by-products would be possessed. Some bioactive components as flavonoids, polysaccharides and chlorogenic acid would be extracted from sunflower by-products, some products would be also produced from those, such as protein feed, adsorbent and package material and so on.
