摘要: 以东北野生鹿蹄草为原料,利用超声辅助提取技术进行提取,在单因素实验的基础上对提取条件进行了考察,根据CCD(Central Composite Design)实验设计原理,采用3因素3水平的响应面分析法,以鹿蹄草中主要黄酮2″-O-没食子酰基金丝桃苷(2″-O-galloylhyperin)为指标,对提取过程进行优化,得到最佳工艺参数为:提取时间45 min,超声功率40 kHz,提取次数3次,提取温度60℃,液固比33∶1,乙醇浓度50%。在最佳提取条件下,2″-O-没食子酰基金丝桃苷的提取率可达5.024 mg·g-1

Abstract: Based on the preliminary experiments, a three-variable, three-level Central Composite Design (CCD) was performed to study the ultrasound-assisted extraction of 2″-O-galloylhyperin from Pyrola calliantha H.Andr.. The optimum parameters were as follows: extraction time 45 min, ultrasound power 40 kHz, three extraction cycles, extraction temperature 60℃, liquid/solid ratio 33∶1, ethanol concentration 50%. Under the optimal conditions, the average extraction yields of 2″-O-galloylhyperin was 5.024 mg·g-1.
