| 摘 要： | 为建立山楂中熊果酸的提取工艺及测定方法,实验以熊果酸的得率为检测指标,采用正交设计L_(16)(4~5),考察提取时间A、乙醇浓度B、料液比C三个影响因素,用高效液相色谱法进行含量测定。结果表明,因素B和C对熊果酸的得率有显著影响,因素A影响不明显,最佳工艺条件为A_3B_4C_3,即每次用12倍量的95％乙醇提取3h。 |

| Abstract: | To find out the optimum extraction process for extracting ursolic acid from the fruit of Crataegus pinnatifida,influencing factors such as extracting time A,ethanol concentration B and the ratio of solid to liquid C were studied by using L_(16)(4~5) orthogonal experimental design guided by the extraction yield.The amount of ursolic acid was determined by HPLC at the same time.Results show that factors B and C have significant influence on extraction efficiency,therefore,the optimum extraction process is A_3B_4C_3 which uses 12 times(mass:volume)amount of 95% ethanol for 3 hours each time. |
| Keywords: | Crataegus pinnatifida ursolic acid extraction process |
