目的:建立桐叶中齐墩果酸和熊果酸的含量测定方法。方法:采用HPLC法,色谱柱为Promosil C18柱(4.6 mm×250 mm,5μm),流动相为乙睛-甲醇-水-磷酸(66∶12∶22∶0.02),流速为1.0 mL·min-1,检测波长为210 nm,柱温为25℃,进样量为20μL。结果:齐墩果酸在0.1292-1.5504μg范围内呈良好的线形关系(r=0.9999),平均回收率为100.1%,RSD%为3.4%(n=6)。熊果酸在0.2428-2.9136μg范围内呈良好的线形关系(r=0.9999),平均回收率为99.3%,RSD%为2.2%(n=6)。结论:该方法操作简单、准确,重现性好,可用于桐叶的质量控制。
目的:建立桐葉中齊墩果痠和熊果痠的含量測定方法。方法:採用HPLC法,色譜柱為Promosil C18柱(4.6 mm×250 mm,5μm),流動相為乙睛-甲醇-水-燐痠(66∶12∶22∶0.02),流速為1.0 mL·min-1,檢測波長為210 nm,柱溫為25℃,進樣量為20μL。結果:齊墩果痠在0.1292-1.5504μg範圍內呈良好的線形關繫(r=0.9999),平均迴收率為100.1%,RSD%為3.4%(n=6)。熊果痠在0.2428-2.9136μg範圍內呈良好的線形關繫(r=0.9999),平均迴收率為99.3%,RSD%為2.2%(n=6)。結論:該方法操作簡單、準確,重現性好,可用于桐葉的質量控製。

Objective:To establish a method for the determination of oleanolic acid and ursolic acid in Paulownia Leaves. Methods:HPLC was applied, and column was Promosil C18(4.6 mm×250 mm, 5 μm); mobile phase was acetonitrile- methanol -water-phosphoric acid (66∶12∶22∶0.02);flow rate was 1.0 mL·min -1; the detection wavelength was 210 nm; column temperature was 25 ℃; the injection volume was 20 μL. Results:Oleanolic acid in the range of 0.1296-1.5504 μg showed good linear relationship (r=0.9999),and the average recovery was 100.1%; RSD% was 3.4% (n=6). Ursolic acid in the range of 0.2428-2.9136 μg showed good linear relationship (r =0.9999), and the average recovery was 99.3% ; RSD% was 2.2% (n =6). Conclusion: The method is simple, accurate, reproducible,and can be used for Paulownia Leaves quality control.
