In this study,α-amylase inhibitor was extracted from rizhao green tea with hot water. The effect of solid-liquid ratio,extraction time and temperature on extraction of α-amylase inhibitor were studied through single factor test. Extraction conditions of α-amylase inhibitor were optimized by orthogonal experiment. The results showed that the optimum extraction ofα-amylase inhibitor was solid-liquid ratio of 1:20 (g/mL), the extraction time of 1 h, extraction temperature of 100 ℃. Hot water extraction is an effective method for extraction ofα-amylase inhibitor from green tea.
