Abstract:
The optimization of extraction of total flavonoids from Chinese pine pollen were studied by Response surface design (RSD). Results showed that the optimal reflex temperature, ethanol content, ratio of the liquid to solid and reflex extraction time were 80 ℃, 56%, 17.9:1 and 3.2 h, respectively. Under these conditions, the yield of flavonoids was 1.49%.
