摘要: | 目的:测定九节菖蒲中酚酸类成分含量并优化其提取工艺。方法:采用高效液相色谱法测定九节菖蒲中单阿魏酰酒石酸、阿魏酸的含量;以2种指标性成分的总含量为指标,以提取溶剂的体积分数、提取溶剂量、提取次数和提取时间为因素,采用正交试验法优化提取工艺,并进行验证试验。结果:九节菖蒲药材中单阿魏酰酒石酸和阿魏酸的含量分别为0.059%、0.002 5%。优化后的提取工艺为将30%乙醇600 mL加至20 g 药材中提取2次,每次90 min;验证试验中2种成分在提取物中的平均含量分别为0.297 1%(RSD=3.64%,n=3)、0.004 1%(RSD=5.11%,n=3)。结论:建立了九节菖蒲中单阿魏酰酒石酸、阿魏酸含量的测定方法;优化后的提取工艺稳定、可行。 |
ABSTRACT: | OBJECTIVE: To determine the content of phenolic acids from Anemone altica, and optimize its extraction technology. METHODS: HPLC was used to determine the contents of mono-ferulyl tartaric acid and ferulic acid from A. altica; using the total contents of 2 index components as index, volume fraction of extraction solvent, extraction solvent volume, extraction times and extraction time as factors, orthogonal test was used to optimize extraction technology, and verification test was conducted. RESULTS: The contents of mono-ferulyl tartaric acid and ferulic acid were 0.059%, 0.002 5%, respectively; the optimal extraction technology was as follow as 30% ethanol 600 mL added to 20 g medicinal material, extracted twice, 90 min every time. In verification test, the average contents of 2 components in extract were 0.297 1% (RSD=3.64%, n=3), 0.004 1% (RSD=5.11%, n=3). CONCLUSIONS: A method for contents determination of mono-ferulyl tartaric acid and ferulic acid from A. altica is established; optimized extraction technology is stable and feasible. |
