摘要
目的考察不同采收期连翘、金钟花果实中连翘酯苷和连翘苷的含量。方法采用HPLC-PDA法,以Diamonsil-C18(4.6mm×250mm,5μm)为色谱柱,流动相为甲醇-水,梯度洗脱,流速为1mL/min,检测波长270nm。结果连翘果实中连翘酯苷的含量远高于金钟花,金钟花果实中不含连翘苷。结论不同采收期连翘、金钟花果实中连翘酯苷和连翘苷的含量有较大差别,金钟花不应混作连翘使用。
Objective To study the content of forsythiaside and forsythin from fruits of Forsythia suspensa and Forsythia viridissima Lindl collected in different periods. Methods Samples were dealt by HPLC-PDA with Diamonsil-C18 （4.6 mm × 250 mm, 5μm） column. The mobile phase consisted of methanol-water, gradient elution, the flow rate was 1.0 mL/min. The UV detection was set at 270 nm. Results The content of forsythiaside from fruits of Forsythia suspensa was much higher than that from fruits of Forsythia viridissima Lindl. And there was no forsythin from fruits of Forsythia viridissima Lindl. Conclusion There was much difference in content of forsythiaside and forsythin from the two kinds of fruits above. Forsythia viridissima Lindl should not be used as Forsythia suspensa.
