摘要
以景天三七为试材,以齐墩果酸含量为指标,运用微波辅助法进行正交实验,研究微波辅助法提取景天三七中齐墩果酸的最佳工艺条件。结果表明:微波辅助法提取的最佳工艺条件为乙醇浓度70%,微波温度70℃,微波时间5min,料液比1∶20g/mL,齐墩果酸的提取率最高,为1.663%。该试验结果表明,齐墩果酸正交提取工艺的研究结果可靠,结果稳定,可用于景天三七中齐墩果酸的提取。
Taking Sedum aizoon L. as material,with olearolic acid content as index,microwave-assisted method by the orthogonal design was used, the optimum extraction technology of oleanolic acid from Sedum aizoon L. were studied. The results showed that the optimum technological conditions of microwave-assisted extraction method were： 70% ethanol concentration,70℃ microwave temperature,microwave 5 min, 1 ： 20 g/mL material-solution ratio the extraction rate of oleanolic acid was 1. 663 ;. The procedure is reliable,and the results are in line. The technology can be used for extraction of oleanolic acid from Sedum aizoon L..
