| 目的：建立HPLC法及UPLC-MS法测定芫花中银椴苷、木犀草素、芹菜素、绿原酸、羟基芫花素、芫花素及芫花酯甲7种化学成分含量的方法，分析芫花炮制前后化学成分的变化。方法：采用HPLC法，测定银椴苷、木犀草素、芹菜素、绿原酸、羟基芫花素和芫花素6种成分的含量，色谱柱为AgilentEclipse Plus C18（250 mm×4.6 mm，5 μm），流动相为乙腈（A）-0.1%甲酸（B）梯度洗脱，流速为1.0 mL·min-1，进样量10 μL。同时采用UPLC-MS方法测定芫花酯甲的含量，色谱柱为ACQUITYUPLC HSS T3 C18 色谱柱（2.1 mm×100 mm，1.8 μm），流动相为乙腈（A）-0.1%甲酸（B）梯度洗脱，流速0.3 mL·min-1，柱温35 ℃，进样量1 μL。结果：7种成分的含量由高到低依次为芫花素＞绿原酸＞银椴苷＞芹菜素＞羟基芫花素＞木犀草素＞芫花酯甲。芫花炮制后7种成分的含量均发生一定程度的变化，其中绿原酸成分在炮制后含量有升高有降低，变化不明显；对于银椴苷和芹菜素成分，炮制后含量降低；对于木犀草素、羟基芫花素和芫花素3个成分，炮制后含量升高；对于芫花酯甲成分，炮制后含量降低。结论：该方法简便、灵敏、高效，为考察芫花饮片炮制前后的质量变化提供了技术支持。 |

| Objective: To establish HPLC method and UPLC-MS method for the determination of tiliroside,luteolin, apigenin, chlorogenic acid, hydroxy genkwanin, genkwanin and yuanhuacine in Daphne genkwa. Toanalyze the contents change of 7 chemical components before and after processing. Methods: The contents oftiliroside, luteolin, apigenin, chlorogenic acid, hydroxy genkwanin and genkwanin were determined by HPLC.The chromatographic column was Agilent Eclipse Plus C18 (250 mm × 4.6 mm, 5 μm) with mobile phase gradient elution of acetonitrile (A)-0.1% formic acid (B). The fl ow rate was 1.0 mL·min-1 and the injection volume was 10μL. The content of yuanhuacine was analyzed by UPLC-MS. The chromatography was performed on ACQUITYUPLC HSS T3 C18 column (2.1 mm × 100 mm, 1.8 μm) with gradient elution of acetonitrile (A)-0.1% formicacid (B) as mobile phase at the fl ow rate of 0.3 mL·min-1. The column temperature was 35 ℃ and the injectionvolume was 1 μL. Results: The contents of the 7 components in the order of high to low were genkwanin ＞chlorogenic acid ＞ tiliroside ＞ apigenin ＞ hydroxy genkwanin ＞ luteolin ＞ yuanhuacine. The contents of 7components in Daphne genkwa were changed to a certain extent after processing, and the content of chlorogenicacid was increased and decreased after processing, while the change was not obvious. The contents of tilirosideand apigenin were decreased after processing. The contents of luteolin, hydroxy genkwanin and genkwanin wereincreased after processing. For yuanhuacine, its content was tended to decrease after processing. Conclusion: Themethod is simple, sensitive and effi cient, and provides technical support for investigating the quality changes ofDaphne genkwa decoction slices before and after processing. |
