摘要

目的 建立沙棘酚类特征成分含量测定及其酚类特征图谱质量表征关联分析方法,应用关联分析评价模式,以有效、精准地评价沙棘药材质量.方法 采用二极管阵列检测器液相色谱法(HPLC-PDA)对11批沙棘药材中的酚类特征成分(原儿茶酸、鞣花酸、水仙苷、槲皮素、异鼠李素)进行含量测定,建立沙棘酚类特征图谱,基于特征图谱中特征峰的梳理及所属化学类型对11批沙棘药材进行质的表征,基于特征图谱中特征成分原儿茶酸、鞣花酸、水仙苷、槲皮素、异鼠李素及酚酸类(以原儿茶酸表征)、黄酮类(以水仙苷表征)的含量和峰面积分别对11批沙棘药材进行量的表征,并基于基准药材对11批沙棘药材质与量的表征结果进行关联性分析.结果 原儿茶酸、鞣花酸、水仙苷、槲皮素、异鼠李素等特征成分均具有良好的线性关系,方法学考察符合定量要求.以批号7为基准药材,在沙棘酚类特征图谱中共含有18个特征峰,其中酚酸类成分特征峰3个,黄酮类成分特征峰15个,11批药材色谱图中均含有此18个特征峰.采用质量表征关联分析与评价模式,得出批号8、7、10、4、5、11、1特征成分含量总体较高,批号6、2、3、1、11与基准药材关联性最高,综合评价得出批号1、11、8、6、7优良度居前.结论 建立的沙棘酚类特征成分含量测定方法简便、准确,构建的沙棘酚类特征图谱质量表征关联分析模式用于分析沙棘药材质量与应用有效性,可有效精准地评价沙棘质量.%Objective To establish an analysis method for quantitatively determining phenolic character-istic components and correlation analyzing their quality representation of specific chromatograms in Shaji (Seabuckthorn Fruit,Hippophae rhamnoides),and to review the quality of Shaji effectively and accurate-ly by applying association analysis-reviewing mode.Methods HPLC-PDA method was used to quantita-tively determine the content of phenolic characteristic components in 11 batches of Shaji(protocatechuic acid,ellagic acid,narcissin,quercetin,isorhamnetin),and to establish phenolic specific chromatograms of Shaji.The quality of 11 batches of Shaji was characterized based on teasing characteristic peaks and chemical types.The quantity of 11 batches of Shaji was characterized based on quantity and peak areas of protocatechuic acid, ellagic acid, narcissin, quercetin, isorhamnetin, phenolic acids(represented by protocatechuic acid)and flavonoids(represented by narcissin)in the specific chromatograms.The characterized results of quality and quantity of 11 batches of Shaji were given association analysis based on baseline material of Shaji.Results The characteristic components of protocatechuic acid, ellagic acid,narcissin,quercetin,isorhamnetin all had good linear correlation,and the results of methodological investigation were in accordance with the quantitative determination requirements.Taken batch 7 of Shaji as baseline material, there were totally 18 characteristic peaks in phenolic specific chromatograms of Shaji,including 3 peaks of phenolic acids and 15 peaks of flavonoids, and all 18 characteristic peaks appeared in the chromatograms of 11 batches of Shaji.The quantity of characteristic components were higher in batch 8, 7, 10, 4, 5, 11 and 1 after analyzed and reviewed by using association analysis-reviewing mode.The relevance of batch 6, 2, 3, 1 and 11 was the highest with baseline material of Shaji.Comprehensive reviewing showed that the excellent extents of batch 1,11,8,6 and 7 were prior. Conclusion The quantitative determination method of phenolic characteristic components in Shaji estab-lished in this study is easy and accurate.The association analysis-reviewing mode for quality characteriza-tion of phenolic specific chromatograms can be used for analyzing the quality and application validity of Shaji and reviewing quality of Shaji effectively and accurately.
