[Objective] The study aimed to explore the microwave-assisted extraction technics of red pigment from Embelia laeta pulp.[Method] The red pigment of Embelia laeta pulp was extracted by the microwave-assisted extraction.And its optimum conditions were found by the single factor experiment,orthogonal test and extraction times experiment.[Result]The optimum extraction conditions of microwave-assisted extraction were as follows: the ratio of material to citrate phosphate buffer extractant(pH 3.0)was 1∶ 70,microwave power was 450 wattage,microwave treatment time was 180 seconds,extracting times was 2 times.Under these conditions,the extraction rate of pigment reached 90.46%,and the yield rate of total anthocyanin from the pulp was up to 50.66 mg/100 g.[Conclusion]The microwave-assisted extraction is a more effective and economical method to extract red pigment from Embelia laeta pulp.
