TITLE:
摘要: 目的:考察门氏护胃方中连翘单药及与其他药材配伍煎煮前后连翘酯苷A和连翘苷提取率的变化。方法:采用高效液相色谱法测定连翘单味药材(5 g×7付)、连翘(5 g×7付)与姜半夏配伍、门氏护胃方[包括连翘(5 g×7付)、姜半夏等6味药材]经水煎煮后药液中连翘酯苷A和连翘苷的提取量并计算提取率。色谱柱为 Diamonsil C18,流动相为乙腈-0.2%甲酸溶液,梯度洗脱,检测波长为278 nm,柱温为30 ℃,流速为1.0 mL/min。结果:连翘酯苷A与连翘苷进样量线性范围分别为0.61~6.1、0.246~2.46 μg(r=0.999 7、0.999 9),在精密度、稳定性(20 h内)和重复性试验中RSD均<2%(n=6),平均回收率为96.10%~99.37%(RSD≤2.36%,n=6);在连翘单味药材中,连翘酯苷A和连翘苷的提取率分别为96.90%、66.67%;在连翘-姜半夏配伍样品水煎液中,二者的提取率分别为101.61%、54.55%;在门氏护胃方样品水煎液中,二者的提取率分别为98.39%、84.85%。结论:连翘与姜半夏配伍后连翘酯苷A的提取率增加、连翘苷的提取率略有减少;连翘与门氏护胃方中其他药材配伍后,二者的提取率均略有增加。
ABSTRACT: OBJECTIVE: To investigate the changes of extraction rates of forsythiaside A and forsythin in Forsythia suspensa compatible with other medicinal material of Menshi huwei formula before and after decoction. METHODS: HPLC method was used to determine the extraction amounts and to calculate the extraction rates of forsythiaside A and forsythin in F. suspensa (5 g×7 doses), F. suspensa (5 g×7 doses) compatible with Pinelliae rhizoma praeparatum cum zingibere et alumine (PRZA), Menshi huwei formula [including 6 ingredients as F. suspense (5 g×7 doses), PRZA] after decocted with water. The determination was performed on Diamonsil C18 column with mobile phase consisted of acetonitrile-0.2% formic acid solution (gradient elution). The detection wavelength was set at 278 nm, and the column temperature was 30 ℃. The flow rate was 1.0 mL/min. RESULTS: The linear range of forsythiaside A and forsythin were 0.61-6.1, 0.246-2.46 μg (r=0.999 7, 0.999 9), respectively; RSDs of precision, stability (within 20 h) and reproducibility tests were all lower than 2% (n=6). Average recovery rates were 96.10%-99.37% (RSD≤2.36%,n=6) respectively. In F. suspensa, extraction rates of forsythiaside A and forsythin were 96.90% and 66.67%. In F. suspensa compatible with PRZA, extraction rates of them were 101.61% and 54.55%. In Menshi huwei formula, extraction rates of them were 98.39% and 84.85%. CONCLUSIONS: After F. suspensa is compatible with PRZA, the extraction rates of forsythiaside A is increased while forsythin is decreased. After compatible with other medicinal material in Menshi huwei formula, extraction rates of both are increased slightly.
