摘　　要：目的建立基于药物体系的栀子特征图谱质量表征关联分析方法与评价模式,有效精准地评价栀子饮片质量。方法运用所建立的HPLC-PDA法表征栀子药物体系特征图谱质量,基于特征图谱中特征峰的数量及所属化学类型对16批栀子饮片进行质的表征,基于特征图谱中特征指标性成分栀子苷、京尼平龙胆双糖苷和绿原酸的含量及环烯醚萜类(以栀子苷表征)、苯丙酸类(以绿原酸表征)的含量,同时采用香草醛-高氯酸显色法测定栀子总萜含量,三氯化铁-铁氰化钾显色法测定栀子总酚含量,对16批栀子饮片进行量的表征,并基于基准饮片将16批栀子饮片质与量的表征结果分别进行关联性分析。结果以批号6为基准,栀子饮片特征图谱中共含有特征峰9个,其中环烯醚萜成分特征峰4个,苯丙酸类成分特征峰5个,16批饮片色谱图中均含有此9个特征峰。批号3、4、7、8、13有效指标性成分总体含量高于基准批号6,批号7、1、9、4、3、12、5、14与基准批号6关联性最高,综合评价得出批号3、4、6、7优良度居前。结论建立了栀子饮片的HPLC特征图谱质量表征方法,并结合总酚及总萜含量测定对16批栀子饮片进行质量表征。所建立的基于药物体系的栀子特征图谱质量表征关联分析模式,关注了栀子饮片质量整体关联性与应用有效性,能有效精准地评价栀子饮片质量。Objective To establish the quality representation and correlation analysis method based on the characteristic spectrum of medicinal system of raw decoction pieces of Zhizi （ Fructus Gardenia） , so as to evaluate quality of Zhizi pieces effectively and accurately. Methods Using established HPLC-PDA method to characterize the quality of Zhizi characteristic chromatogram of medicinal system. The quality of 16 batches of Zhizi pieces was represented according to the number and chemical type of characteristic peaks on chromatogram, and the quantity of 16 batches of Zhizi pieces was represented based on the con- tent of characteristic index components of gardenoside, genipin 1-gentiobioside, chlorogenic acid, iri- doids （represented by gardenoside） and phenylpropionic acids （represented by chlorogenic acid）. The content of total terpenoids was determined by using vanillin-perchloric acid colorimetric method and the content of total phenols was detected by using chloride-potassium ferricyanide colorimetric method. Corre- lation analysis of quality and quantity representations was then performed referring to the benchmark pieces. Results As the reference substance, characteristic spectrum of Lot. 6 contains nine characteristic peaks including four peaks of iridoids and five peaks of pheny｜propionic acids, which all appeard on the chromatograms of 16 batches Zhizi pieces. Lot. 3, 4, 7, 8, 13 Zhizi pieces had more effective index components than that of Lot. 6, and Lot. 7, 1,9, 4, 3, 12, 5, 14 pieces had higher correlation degree to Lot. 6. After comprehensive evaluation, the quality of Lot. 3, 4, 6,7 were better. Conclusion The established HPLC methods by quality and quantity representation of characteristic spectrum of 16 batches of Zhizi pieces is simple and accurate. And the evaluation mode of quantity and quality and their correlation based on Zhizi medicinal system, concerning on systemic correlation and application validity, can evaluate the quality of Zhizi pieces effectively and accurately.
