| 中文摘要: |
| 采用微波辅助浊点提取悬铃木球叶中的黄酮类化合物。在单因素试验的基础上,0.6%吐温-80的乙醇溶液作为浊点萃取剂,通过响应面法优化确立悬铃木黄酮类化合物的最佳提取工艺条件：微波功率410 W,提取时间7 min,液料比49:1 mL?g-1,实际测得黄酮平均得率1.480 mg?g-1。并对黄酮类化合物进行了分离纯化,得到2个化合物,经理化常数测定和波谱解析鉴定,化合物1为3,5,7-三羟基黄酮,分子式为C15H10O5；化合物2为山奈酚,分子式为C15H10O6。 |
| 英文摘要: |
| The flavones in the balls and leaves of platanus were extracted by microwave assisted cloud point extraction. Based on the single factor test, 0.6% tween-80 was applied to study the effects of microwave power, extraction time and liquid-solid ratio on extraction rate of total flavones. The optimal extraction conditions were as follows: microwave power 410 W, extraction time 7 min and liquid-solid ratio 49:1ml/g, with the extraction rate of total flavones 1.480mg/g. After separation and purification, two compounds were got from the flavones mixture, it was found that one compound is 3,5,7-Trihydroxyflavone(C15H10O5) and another compound is 3,5,7-Trihydroxy-2-(4-hydroxyphenyl)- 4H-chromen-4-one (C15H10O6) by spectra analysis appraisal. |
