| 中文摘要: |
| 光枝勾儿茶是民族中药材，为研究同时提取光枝勾儿茶中芦丁和槲皮素的最佳条件，采用
回流提取法、响应面分析法，考察乙醇体积分数、提取温度、料液比3 个因素及其交互作用和提取时间
对提取工艺的影响。结果表明，光枝勾儿茶芦丁和槲皮素的最佳提取条件为乙醇体积分数73.72%、温度
60.52℃、液料比32.21 mL/g，提取时间3 h，芦丁、槲皮素的提取率分别为18.55、0.36 mg/g，通过试验验证
得到芦丁、槲皮素的提取量平均值分别为18.48、0.35 mg/g，与理论值相比误差小。试验结果为光枝勾儿茶
芦丁和槲皮素的开发和利用提供理论依据。 |
| 英文摘要: |
| Berchemia polyphylla var. leioclada. is a national medicine plant. In order to find the optimum
condition of rutin and quercetin from B. polyphylla var. leioclada. reflux extraction method and surface response
analysis were used，ethanol concentration，extraction temperature，solid-liquid ratio factors and their ineraction
and extracting time were designed to optimize the extracting process. The results showed that the best extraction
condition of rutin and quercetin were selected with 73.72% alcohol，60.52℃ and 32.21 mL/g of solid-liquid
ratio，extracting time was 3 h. The extraction rates of rutin and quercetin were 18.55 and 0.36 mg/g，respectively.
Through experiment study，the average of rutin and quercetin were 18.48 and 0.35 mg/g，respectively，which had
a lillte error to the theory value. The results provide a theoretical basis for further development and use of rutin and
quercetin from B. polyphylla var. leioclada. |
