青藏高原藏木香总黄酮提取工艺研究及含量测定
Study on the extraction technique and quantification of total flavonoids in Inula racemosa grown in Qinghai-Tibet plateau
摘要
Abstract
Objective:Aim to study the best conditions of extraction techniques for total flavonoids in Inula racemosa.Methods: The best conditions of extraction technique for total flavonoids were optimized with orthogonal experiment.Developed by ethanol solution with different concentrations, solvent multiples and extraction duration,determination of total flavonoids with UV-spectrophotometry was made.Results: Ethanol concentration was the major factor for determining total flavonoids contents.The best conditions for the extraction techniques of total flavonoids were:75％ ethanol which was 20 times of the medicine amount, reflux extracting 2 hours.The yield of total flavonoids in Inula racemosa was estimated at 0.28mg/g.Conclusion:The extraction techniques are feasible and the UV-spectrophotometric method is simple,quick and accurate.关键词
