杨梅渣中多酚类物质的超声波辅助提取研究

摘要

杨梅中的多酚类物质具有独特的生物活性。利用超声波辅助提取杨梅渣中的多酚类物质、总花色苷,得出的最佳提取条件为20kHz的超声频率、30W的超声功率,在60℃下提取70min。%Polyphenols in the pomace of bayberry（Myrica rubra Sieb.et Zucc.）have some particular biological activities.Ultrasound assisted extraction was used to extract polyphenols from bayberry pomace.A frequency of 20kHz and a ultrasonic power of 30W were suitable to extract the polyphenols at 60℃ for 70min.
