摘要
[目的]微波辅助提取玉竹糖蛋白并对其抗氧化能力进行研究.[方法]以玉竹为原料,采用微波辅助提取糖蛋白,通过单因素和正交试验得到最佳提取工艺,并考察玉竹糖蛋白的抗氧化性.[结果]微波辅助提取玉竹糖蛋白的最佳工艺为料液比1∶30 g/mL、微波功率420W、提取时间4min、提取次数3次,在此条件下,验证玉竹糖蛋白得率为8.85％.玉竹糖蛋白具有显著的还原力和清除DPPH自由基的能力,但弱于VC.[结论]微波辅助提取玉竹糖蛋白是一种经济有效的办法,可为进一步开发玉竹产品提供依据.
Abstract
[Objective] To extract glycoprotein from Polygonatum odoratum (Mill.) Druee by microwave-aided extraction method,and to research its antioxidant activities.[Method] With P.odoratum as the research materials,glycoprotein was extracted by microwave-aided method.The optimal extraction technology of glycoprotein was obtained by single factor test and orthogonal test.Antioxidant activity of glycoprotein was investigated.[Result] The optimal extraction technology was as follows:1∶30 g/mL solid-liquid ratio,420 W microwave power,4 min extraction time and 3 extraction times,Under these conditions,the extraction rate of glycoprotein was 8.85％.Glycoprotein in P.odoratum had significant reducing power and scavenging activity to DPPH radicals scavenging,but they were both lower than those of Vc.[Conclusion] Extracting glycoprotein from P.odoratum by microwave-aided extraction method is an economical and efficient method,Which provides references for the further development of P.odoratum products.
