Objective: To investigate the comprehensive extraction of flavonoids and polysaccharides from fermented rattan. Methods: According to the result of single factor experiment, the comprehensive extraction process of flavanone and polysaccharide was optimized by response surface methodology. Results: The optimum extraction conditions were: extraction temperature 96 ℃, time 1.6 h, solid-liquid ratio 1:21. Under these technological conditions, the yield of total flavonoids was 22.94% and the yield of polysaccharide was 2.13%. Conclusion: This study provides a reference for the comprehensive extraction technology of flavanone and polysaccharide, which is beneficial to the comprehensive development and utilization of rattan tea resources.
