【摘要】 采用超声辅助浸取毛竹叶中的黄酮类化合物(以水为溶剂)．考察了超声强度、作用时间等因素对提取速率、得率的影响,发现超声能提高提取速率,对最终黄酮得率也有提高,提取速率随着超声功率增大有所增加。更多还原

【Abstract】 Ultrasonically assisted flavoniods extraction in Phyllostachys pubescens leaves was researched, including the influences of ultrasonic power and ultrasonic processing time on the yield of flavoniods. The results show that the application of ultrasonic to water extraction can reduce extraction time and increase maximum yield, and that the extraction speed increases with ultrasonic power.更多还原
