摘 要 目的 建立平火茶标准汤剂指纹图谱和多指标含量测定的方法,并探究饮片-标准汤剂化学成分的量值传递关系。方法
制备15批平火茶标准汤剂,测定其出膏率;采用高效液相色谱(HPLC)法建立该制剂的指纹图谱,并进行相似度评价和共有峰确
定,同时进行化学计量学分析;同法测定该制剂中指标性成分含量并计算含量的转移率。色谱柱为Venusil C18,流动相为乙腈-0.1%
磷酸溶液(梯度洗脱),柱温为30 ℃,检测波长为238 nm(0~37 min、85~102 min)、330 nm(37~85 min),流速为1.0 mL/min,进样

ABSTRACT OBJECTIVE To establish the fingerprint of Pinghuo tea standard decoction and a method for determination of
multi-component to clarify the transfer relationship of quantities and quality from pieces and standard decoction. METHODS
Fifteen batches of Pinghuo tea standard decoction were prepared and the extract rate was determined; the fingerprint of the
preparation was established by using high-performance liquid chromatography(HPLC); the similarity evaluation and the
determination of common peaks were performed, and chemometric analysis was performed; the same method was used to
determine the content of indicator components and the transfer rate was calculated. The chromatographic column was Venusil C18
column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution); the column temperature was
30 ℃, and the detection wavelengths were 238 nm (0-37 min, 85-102 min) and 330 nm (37-85 min) at a flow rate of 1.0 mL/min
with an injection volume of 10 μL. RESULTS The similarity of HPLC fingerprints for 15 batches of Pinghuo tea standard
decoction was not lower than 0.968. A total of 24 common peaks were calibrated and 9 peaks were recognized, which were as
follows neochlorogenic acid (peak 3), chlorogenic acid (peak 6), geniposide (peak 9), glycyrrhizin (peak 10), galuteolin (peak
11), isochlorogenic acid A (peak 14), luteolin (peak 21), kaempferol (peak 23) and glycyrrhizic acid (peak 24). Cluster
analysis, principal component analysis and orthogonal partial least squares discriminant analysis showed consistent results, all of
which could classify the 15 batches of samples into three categories. The linear range of indicator components in 15 batches of
Pinghuo tea standard decoction, such as geniposide, luteolin, isochlorogenic acid A, glycyrrhizin, and glycyrrhizic acid,
were 0.020 580-0.411 600, 0.001 617-0.080 850, 0.006 076-
