摘要: 以烟草叶片为原料,用正交试验法优化了烟草中辅酶Q10的匀浆提取工艺,考察了匀浆时间、乙醇体积分数、液料比和提取次数4个因素对辅酶Q10提取率的影响,确立了烟草中辅酶Q10的优化匀浆提取工艺条件为:提取溶剂为85%乙醇,匀浆时间6 min,液料比9∶1(mL/g),提取次数2次。将该法与索氏提取进行了对比。结果表明,匀浆提取烟草中辅酶Q10的提取率为12.82 μg·g-1,与索氏提取的提取率相当,但匀浆提取所用提取时间短,提取溶剂用量少,因此匀浆法具有明显的优势。

Abstract: Using tobacco leaves as materials, the homogenate extraction technology of coenzyme Q10 (CoQ10) in tobacco was optimized by orthogonal experiments. The effect of homogenate time, ethanol volume percent, ratio of liquid to material and number of extraction cycles on the extraction yield of CoQ10 was investigated. The optimized homogenate extraction technology was determined as follows: 85% ethanol as extraction solvent, homogenate time 6 min,ratio of liquid to material 9∶1(mL· g-1), 2 extraction cycles. A comparison between homogenate and Soxhlet extractions was conducted. The extraction yield of CoQ10 was 12.82 μg·g-1 by homogenate extraction, which was almost equivalent to Soxhlet extraction. Homogenate extraction is faster and needs less solvent, thereby homogenate extraction has an advantage over Soxhlet extraction.
