摘 要 ：为了开发银杏花粉深加工产品,以银杏花粉为试材,以其提取液的DPPH清除率为指标,研究加热回流法、超声波法、微波法、超声-微波法提取银杏花粉抗氧化成分的效果,并通过单因素和响应面法对微波法提取工艺进行优化。结果表明,4种提取方法中,微波法提取银杏花粉抗氧化成分的效果最好。微波提取的最佳工艺为:乙醇浓度59.38%、料液比1∶30、微波功率109.85 W、微波时间13 min。本研究为银杏花粉抗氧化成分的开发利用奠定了基础。

Abstract:In order to exploit deep processing products of ginkgo pollen, different extraction methods were studied with DPPH scavenging of the ginkgo pollen extracts as index, including of the heating reflux, ultrasonic, microwave, and ultrasonic-microwave extraction methods. Then, the microwave extraction process was optimized by single factor and response surface methods. The results showed that microwave was the best within the four extraction methods. The microwave extraction process optimized was as follows: 59.38% ethanol, solid-liquid ratio of 1∶30, microwave power of 109.85 W, and microwave time of 13 min. This study laid a foundation for exploitation of the antioxidant components from ginkgo pollen.
