摘 要 目的 建立不同产地皂角刺的多指标定量检测方法,并评价其质量差异。方法 采用高效液相色谱-一测多评(HPLC-
QAMS)法同时检测皂角刺中原儿茶酸、香草酸、异东莨菪内酯、滨蒿内酯、异牡荆素、黄颜木素、花旗松素、漆黄素、槲皮素、山柰
酚、刺囊酸、白桦脂酸、β-谷甾醇、豆甾醇的含量,色谱柱为Kromasil C18,流动相为0.2%磷酸-乙腈溶液(梯度洗脱),检测波长针对
不同指标成分分别为254、360、210 nm,柱温为30 ℃,流速为1.0 mL/min,进样量为10 μL;按照《中国药典》方法检测浸出物和总灰
分含量;利用化学计量学、加权逼近理想解排序(TOPSIS)分析、Logistic回归模型对不同产地30批(编号S1~S30)皂角刺样品进
行质量差异评价。结果 上述 14 种成分依次在 1.55~77.50、0.71~35.50、0.28~14.00、0.96~48.00、1.77~88.50、0.09~4.50、
4.65~232.50、1.49~74.50、0.37~18.50、1.18~59.00、7.35~367.50、3.58~179.00、0.49~24.50、0.21~10.50 μg/mL 质量浓度范围
内线性关系良好(r 均大于 0.999),精密度、稳定性(24 h)及重复性的 RSD 均小于 2.00%,平均加样回收率为 96.99%~100.13%
(RSD均小于2.00%),相对校正因子重复性良好。浸出物和总灰分含量分别为4.2%~12.5%和0.5%~2.3%。QAMS法与外标法
所测得的14种成分的含量差异无统计学意义(P>0.05)。化学计量学分析结果显示,30批皂角刺样品可聚为3类,其中S1~S11
聚为一类,S12~S20聚为一类,S21~S30聚为一类;刺囊酸、白桦脂酸、花旗松素、山柰酚、异牡荆素、滨蒿内酯和原儿茶酸可能是
影响不同产地皂角刺质量的差异成分。加权TOPSIS分析结果显示,30批皂角刺的相对贴近度(Jb )为0.144 5~0.721 8,其中样品
S27 的质量最优(Jb值为 0.721 8)。Logistic 回归模型分析结果显示,样品 S21~S30 为优级,S1~S11 为中级,S12~S20 为差级。
结论 所建立的HPLC-QAMS法操作简便、结果准确,综合评价方法客观、全面,可用于不同产地皂角刺的质量差异评价。

ABSTRACT OBJECTIVE To establish a multi-index quantitative detection method, and to evaluate the quality difference of
Gleditsia sinensis from different producing areas. METHODS The contents of protocatechuic acid, vanillic acid, isoscopoletin,
scoparone, isovitexin, fustin, taxifolin, fisetin, quercetin, kaempferol, echinocystic acid, betulinic acid, β -sitosterol and
stigmasterol were detected by high performance liquid chromatography-quantitative analysis of multi-components by single marker
(HPLC-QAMS). The chromatographic column was Kromasil C18, the mobile phase was 0.2% phosphoric acid-acetonitrile solution
(gradient elution), the detection wavelengths were 254, 360, 210 nm for different index components, the column temperature was
30 ℃, the flow rate was 1.0 mL/min, and the sample injection volume was 10 μL. The contents of extract and total ash were
detected according to the method of Chinese Pharmacopoeia. The quality differences of 30 batches of G. sinensis (No. S1-S30)
from different producing areas were evaluated by chemometrics, weighted technique for order preference by similarity to an ideal
solution (TOPSIS) analysis and Logistic regression model. RESULTS The linear ranges of 14 components were 1.55-77.50, 0.71-
35.50, 0.28-14.00, 0.96-48.00, 1.77-88.50, 0.09-4.50, 4.65-232.50, 1.49-74.50, 0.37-18.50, 1.18-59.00, 7.35-367.50, 3.58-
179.00, 0.49-24.50 and 0.21-10.50 μg/mL, respectively (all r>0.999). The RSDs of precision, stability (24 h) and repeatability
were less than 2.00%; the average recoveries were 96.99%-100.13% (all RSDs<2.00%), and the relative correction factor had
good repeatability. The contents of extract and total ash were
