摘 要 目的：研究藤茶不同极性部位的高效液相色谱（HPLC）指纹图谱与其体内抗炎作用的谱-效关系。方法：取藤茶药材，以
70％乙醇回流提取，再分别以石油醚、氯仿、乙酸乙酯、水饱和正丁醇萃取，或直接以水煎煮，浓缩后获得藤茶不同极性部位。建立
二甲苯致小鼠耳肿胀炎症模型，以地塞米松为阳性对照，分别考察藤茶不同极性部位的抗炎活性。采用HPLC法建立藤茶不同极
性部位的指纹图谱，色谱柱为Poroshell 120 EC-C18，流动相为乙腈-0.1％磷酸水溶液（梯度洗脱），流速为1 mL/min，柱温为25 ℃，
检测波长为365 nm，进样量为5 μL。运用灰色关联度法分析藤茶不同极性部位HPLC指纹图谱共有峰与其抗炎药效之间的谱-效
关系，计算关联系数、关联度并进行排序。结果：小鼠抗炎实验结果显示，藤茶70％乙醇提取总部位、乙酸乙酯萃取部位、水提取
部位的抗炎活性最明显（小鼠耳肿胀抑制率分别为54.07％、30.54％、30.45％）。藤茶不同极性部位HPLC指纹图谱中共确定了5
个共有峰。谱-效关系分析结果显示，5个共有峰的关联度均大于0.6；其中，抗炎效果较强的是3号峰和2号峰（二氢杨梅素），两者
的关联度均大于0.8。结论：藤茶对二甲苯致小鼠耳肿胀的抗炎作用是多组分协同作用的结果；3号峰未知成分和二氢杨梅素可能
是藤茶抗炎作用的主要活性成分。

ABSTRACT OBJECTIVE：To study the spectrum-effect relationship of HPLC fingerprint of different polar parts of Ampelopsis
grossedentata with its in vivo anti-inflammatory effect. METHODS：A. grossedentata was reflux extracted with 70％ ethanol，then
extracted with petroleum ether，chloroform，ethyl acetate and water saturated n-butanol；or it was directly decocted with water and
then concentrated to obtain different polar parts. The xylene-induced mice ear swelling model was established；using dexamethasone
as positive control，anti-inflammatory activity of different polar parts of A. grossedentata was investigated. Fingerprints of different
polar parts of A. grossedentata were established by HPLC. The determination was performed on Poroshell 120 EC-C18 column with
mobile phase consisted of acetonitrile-0.1％ phosphoric acid solution（gradient elution）at the flow rate of 1 mL/min. The column
temperature was 25 ℃ . The detection wavelength was set at 365 nm，and sample size was 5 μ L. The grey ralational analysis
method was used to analyze the spectrum-effect relationship of HPLC fingerprint common peaks of different polar parts of A.
grossedentata with its anti-inflammatory effect. The correlation coefficient and correlation degree were calculated and ranked.
RESULTS：Anti-inflammatory experiment showed that the anti-inflammatory effects of 70％ ethanol extraction part，ethyl acetate
extraction part and water extraction part were the most significant （inhibitory rates of ear swelling were 54.07％ ，30.54％ ，
30.45％ ）. Five common peaks were determined in HPLC fingerprints of different polar parts from A. grossedentata. The
spectrum-effect analysis results showed that the correlation of
