中文摘要:目的:研究不同浓缩方法对丹参提取液的影响。方法:以丹参提取液中丹参素钠、原儿茶醛、咖啡酸、迷迭香酸、丹酚酸B、总酚酸为指标成分,比较常压蒸发浓缩、减压浓缩、纳滤膜浓缩条件下各指标成分的变化情况。结果:常压浓缩、减压浓缩过程丹参素钠、原儿茶醛、咖啡酸、总酚酸含量逐步增加,增幅逐渐减小,常压浓缩含量增幅较减压浓缩大;丹酚酸B含量逐步减小,降幅逐渐减小,常压浓缩含量降幅较减压浓缩大;3种浓缩方法对迷迭香酸均无显著影响。膜浓缩过程对各含量均无显著影响。丹酚酸B降解符合一级反应的特点,常压浓缩降解回归方程为Ln(C)=-0.114 t+2.947 6,减压浓缩降解回归方程为Ln(C)=-0.083 t+2.947 6。结论:丹参提取液中存在热不稳定性成分,在受热条件下,其酚酸类成分会发生降解与转化,生产过程中应严格控制温度、真空度、时间等参数,以保证批间的一致稳定,使用纳滤膜浓缩方法可最大程度地保持与药液物质基础一致。应采用纳滤膜浓缩方法对丹参提取液进行浓缩。 |

Abstract:Objective:To investigate effect of different concentration method on extraction of Salvia miltiorrhiza.Methods:Sodium danshensu,protocatechuic aldehyde,caffeic acid,rosmarinic acid,salvianolic acid B and total phenolic acid were used as marker compounds,the changes of the indexes under the atmospheric concentration,decompress concentration and nanofiltration membrane concentration were compared.Results:The results indicated that the contents of sodium danshensu,protocatechuic aldehyde,caffeic acid and total phenolic acid increased gradually,and the increase gradually slowed down under the atmospheric concentration and decompress concentration,the increasing range was larger in atmospheric concentration.The contents of salvianolic acid B decreased gradually,and the decline gradually decreased,the decreasing range was larger in atmospheric concentration.All the three concentration methods showed no significant difference on the contents of rosmarinic acid.There was no significant difference under the nanofiltration membrane concentration.It shows that the degradation of salvianolic acid B can be expressed as a first order reaction,the degradation regression equation of decompress concentration was Ln(C)=-0.083 t+2.947 6,the degradation regression equation of atmospheric concentration was Ln(C)=-0.114 t+2.947 6.Conclusion:Some compounds of S.miltiorrhiza is thermally unstable,as phenolic acid will degrade under heating conditions.To ensure uniformly stability between different batches of S.miltiorrhiza,parameters should be strictly controlled,such as the heating temperature,time and vacuum degree in the concentrating process.The concentration of nanofiltration membrane have the advantages,the substances are reserved in maximum.The extraction solution of S.miltiorrhiza should be concentrated by nanofiltration membrane enrichment method. |
