摘要:研究了用超声波辅助手段、以水为提取剂从毛杨梅树皮中提取原花色素的工艺方法。最佳提取条件为:超声波频率20 kHz,超声波功率800 W,液料比10∶1(mL∶g),提取温度60℃,每次提取时间75 min,提取2次,提取率为28.2%。该法与常规提取方法相比,具有温度低、用时少、液体处理量小等特点。产物中有效成分质量分数大于60%。定性检测确认是局部棓酰化的原翠雀素。
The ultrasound-assisted technique was researched for extraction of proanthocyanidins from Myrica essulenta bark with water as extracting agent. The suitable extraction conditions were : ultrasonic frequency 20 kHz, ultrasonic power 800 W, materiaL/ liquid ratio 1 : 10 (g: mL), temperature 60 ℃, extraction time 75 min, duplicate extraction. The extraction yield was 28.2 %. By comparision with single-batch extraction, this method has the distinguishing features of: low-temperature, time saving and low liquid amount. The proanthocyanidin content in extract was 60 %, and it was determined as prodelphinidin through qualitative examination.
