摘要
黄酮类化合物是蜂胶制品的主要功能成分,采用乙醇超声波浸提法和超临界CO2萃取法从蜂胶中提取黄酮类化合物,采用液相色谱法测定其黄酮类化合物含量。用四因素三水平正交设计,确定采用乙醇超声波浸提法的最佳工艺参数为:冷浸12h,料液比1∶15,超声提取2次,每次处理时间15min。
Flavonoids is a main functional component in porpolis product. It was extracted from porpolis with alcohol ultrasonic wave process and CO2 supercritical extraction. Their extracted contents were measured by HPLC. An optimal process parameter was determined by orthogonal design L9(3^4), i.e, quench time is 12 h, propolis:alcohol is 1:15, ultrasonic extracting degrees is 2, ultrasonic extraction time is 15 min.
