摘要: 复方罗欧咳祖帕提取物分别用系列浓度乙醇溶液进行洗脱,分离得到4个洗脱部位,采用DPPH自由基清除率、OH自由基清除率、T-AOC总抗氧化能力为指标进行抗氧化活性评价,同时探究复方罗欧咳祖帕不同洗脱部位总多酚和总黄酮含量,通过UHPLC-QE-MS指认复方罗欧咳祖帕中主要黄酮类和酚酸类化合物信息,利用质谱数据库及相应裂解规律匹配法对含有MS数据的峰进行物质鉴定。结果表明:复方罗欧咳祖帕不同洗脱部位均具有抗氧化活性,并呈现一定的量效关系,其中复方罗欧咳祖帕20%乙醇洗脱部位的抗氧化能力较强。复方罗欧咳祖帕总多酚总黄酮含量较高,其不同洗脱部位中20%乙醇洗脱部位总黄酮含量最高(276.24 mg/g),40%乙醇洗脱部位中总多酚含量最高(130.5 mg/g)。UHPLC-QE-MS分析复方罗欧咳祖帕中主要化学成分,正负离子模式共检出99种黄酮、酚酸类化合物。通过对新疆抗哮喘复方罗欧咳祖帕的抗氧化活性及其化学成分进行分析。表明复方罗欧咳祖帕具有较好的抗氧化能力,且含有丰富的黄酮、酚酸类化合物。旨在为复方罗欧咳祖帕物质基础研究提供实验参考。

Abstract:

The extracts of the compound Loki Zupa were eluted with a series of ethanol solutions,and 4 elution sites were separated.The DPPH radical scavenging rate,the OH radical scavenging rate,and the total antioxidant capacity of T-AOC were used as Indexes were used to evaluate the antioxidant activity,and the content of total polyphenols and total flavonoids in different elution parts of the compound Loki Zupa was explored.UHPLC-QE-MS was used to identify the main flavonoids and phenolic acid compounds in the compound Loki Zupa,and the self-built MS database and the corresponding fragmentation law matching method were used to identify the peaks containing MS data.The results showed that the different elution parts of compound Loki Zupa all had antioxidant activity and showed a certain dose-effect relationship.Among them,the 20% ethanol elution part of compound Loki Zupa had stronger antioxidant capacity.The content of total flavonoids in the total polyphenols of compound Loki Zupa is higher,and the total flavonoids content in the 20% ethanol elution part is the highest (276.24 mg/g) in the different elution parts,and the total polyphenol content is the highest in the 40% ethanol elution part (130.5 mg/g).UHPLC-QE-MS analysis of the main chemical components in the compound Loki Zupa,a total of 99 kinds of flavonoids and phenolic acid compounds were detected in the positive and negative ion mode.Through the analysis of the antioxidant activity and chemical components of the Xinjiang anti-asthma compound Loki Zupa.It shows that the compound Loki Zupa has good antioxidant capacity and is rich in flavonoids and phenolic acid compounds.The aim is to provide experimental reference for the research on the material basis of compound Loki Zupa.

Key words: Loki Zupa, antioxidant activity, UHPLC-QE-MS, total flavonoids, total polyphenols
