目的
2
基于药物动力学对香叶木素-7-
O
-葡萄糖苷、香叶木素、芹菜素、香草酸和肉桂酸进行瓜蒌祛痰止咳相关质量标志物(Q-marker)的筛选,并利用多元统计方法对筛选出的候选Q-marker进行评价。
方法
2
随机选取6只健康大鼠,灌胃给予瓜蒌70%乙醇提取物(剂量20 g·kg
-1
)后,于不同时间点从眼眶静脉采血,采用高效液相色谱-三重四级杆串联质谱法(HPLC-QqQ-MS/MS)同时检测血浆中5个瓜蒌活性成分(香叶木素-7-
O
-葡萄糖苷、香叶木素、芹菜素、香草酸、肉桂酸)的血药浓度,主要检测条件为流动相0.2%甲酸水溶液(A)-乙腈(B)梯度洗脱(0~4 min,6%~23%B;4~5 min,23%~59.5%B;5~10 min,59.5%~60%B),流速0.5 mL·min

z
50~1 500;选择药物动力学规律较为明确的成分为瓜蒌祛痰止咳相关候选Q-marker,测定这些成分在9批药材中的含量,主要检测条件与药物动力学研究相同,以含量测定的结果为基础,使用SPSS 21.0进行系统聚类分析和主成分分析(PCA)。
结果
2
药物动力学结果显示,香叶木素-7
-O-
葡萄糖苷、香叶木素、芹菜素、香草酸4个成分的药-时曲线下面积(AUC

;系统聚类分析将9批瓜蒌聚为3类,聚类结果与瓜蒌的品种相关,但也受产地的影响;PCA结果显示,高唐瓜蒌、山西瓜蒌和河北笨瓜蒌的综合评分分别为1.919,1.356,0.299,在所有瓜蒌样品中位于前3位,农科院1号、河北瓜蒌和农科院2号的综合评分分别为-0.804,-1.085,-1.120,在所有瓜蒌样品中位于后3位。
结论
2
香叶木素-7-
O
-葡萄糖苷、香叶木素、芹菜素和香草酸4个成分在药物动力学特征和质量评价等方面符合瓜蒌祛痰止咳相关Q-marker的要求。
Objective
2
Based on pharmacokinetics, the antitussive and expectorant related quality markers (Q-marker) of Trichosanthis Fructus were screened from diosmetin-7-
O
-glucopyranoside, diosmetin, apigenin, vanillic acid and cinnamic acid, and the candidate Q-marker was evaluated by multivariate statistical method.
Method
2
Six healthy rats were randomly selected and the 70% ethanol extract of Trichosanthis Fructus (dose of 20 g·kg
-1
) was given by intragastric administration. Blood was collected from the orbital vein at different time points, and the plasma concentrations of 5 components (diosmetin-7-
O
-glucopyranoside, diosmetin, apigenin, vanillic acid and cinnamic acid) from Trichosanthis Fructus were detected simultaneously by high performance liquid chromatography-triple quadrupole tandem mass spectrometry (HPLC-QqQ-MS/MS). The main detection conditions were as following:mobile phase of 0.2% formic acid aqueous solution (A)-acetonitrile (B) for gradient elution (0-4 min, 6%-23%B; 4-5 min, 23%-59.5%B; 5-10 min, 59.5%-60%B), flow rate of 0.5 mL·min

z
50-1 500. Diosmetin-7-
O
-glucopyranoside, diosmetin, apigenin and vanillic acid with clear pharmacokinetic behaviors were selected as candidate Q-marker about antitussive and expectorant of Trichosanthis Fructus. The contents of these components in 9 batches of medicinal materials were determined and the main detection conditions were the same as the pharmacokinetic study. SPSS 21.0 was used for cluster analysis and principal component analysis (PAC) based on the results of determination.
Result
2
The pharmacokinetic results showed that the area under concentration-time curve (AUC
0-
t
) of 4 components (diosmetin-7-
O
-glucopyranoside, diosmetin, apigenin and vanillic acid) were (111.28±9.94), (27.08±2.76), (1 376.12±101.86), (631.32±64.72) μg·h·L
-1
, respectively. The 9 batches of Trichosanthis Fructus samples were clustered into 3 groups by systematic cluster analysis. The clustering results were related to the variety of Trichosanthis Fructus and also affected by the origin. The PCA results showed that the comprehensive scores of Gaotang Trichosanthis Fructus, Shanxi Trichosanthis Fructus, Hebei Ben Trichosanthis Fructus were 1.919, 1.356 and 0.299, respectively, ranking in the top 3 among all samples. The comprehensive scores of Nongkeyuan No. 1, Hebei Trichosanthis Fructus and Nongkeyuan No. 2 were -0.804, -1.085, -1.120, respectively, which were in the last 3 positions among all samples.
Conclusion
2
The pharmacokinetic characteristics and quality evaluation of diosmetin-7-
O
-glucopyranoside, diosmetin, apigenin and vanillic acid meet the requirements about antitussive and expectorant related Q-marker of Trichosanthis Fructus.
