摘要
以广西宜州野生火棘果为原料,采用超声波辅助溶剂法,对野生火棘果中的原花青素进行提取。选择5个因素进行单因素实验,利用紫外-可见分光光度计测定吸光度,初步确定各因素的最佳条件。用正交实验进一步优化初步的实验结果,最终得出超声波辅助溶剂提取火棘果中原花青素的最佳工艺条件为:按料液比1∶55(g∶mL),往火棘果粉中加入80%的乙醇,在功率175 W、温度70℃的条件下,超声提取60 min,在波长550 nm处测定,得出火棘果中原花青素的提取率为5.95%。
The proanthocyanidins were extracted from wild pyracantha fruit by ultrasound-assisted solvent extraction.The absor-bance of proanthocyanidins was determined by ultraviolet spectrophotometer method.Five factors were selected for single factor experiment,the absorbance was determined by UV-Vis spectrophotometer.The optimum extracting process of pyracanthocyanin with ultrasound-assisted solvent were obtained by orthogonal experiment:ratio of material to liquid was 1:55(g:mL)with 80%ethanol,extracted for 60 min under 175W and 70℃.The wavelength was measured at 550nm,and the nal extraction rate was 5.95%.
