摘要
为准确有效鉴别蛹虫草,采用Luna C18(2)色谱柱(250 mm×4.6 mm,5μm),以甲醇-pH 6.5磷酸盐缓冲液为流动相,流速0.5 mL/min,柱温30℃,梯度洗脱,260 nm波长检测,建立了蛹虫草HPLC特征图谱。以鸟苷、尿苷、胞苷、腺苷、腺嘌呤、虫草素6种标准品做对照,指认了13批样品中的共有特征色谱峰8个,并指认其中的鸟苷峰为参照峰。该方法的精密度、重现性和稳定性均符合要求。该方法可用于蛹虫草的定性鉴别和质量评价。
In order to accurately and effectively identify Cordyceps militaris, its HPLC characteristic chromatogram was established with Luna C18(2)(250 mm×4.6 mm, 5 μm) column in a gradient elution of methanol-phosphate buffer(pH 6.5), at the flow rate of 0.5 mL/min and 30 ℃ column temperature. Guanosine, uridine, cytidine, adenosine,adenine and cordycepin were used as reference standard. Total 8 characteristic peaks in 13 batches of samples were identified and the guanosine peak was identified as the reference peak. The precision, repeatability and stability of this method were all met with the requirements. This method could be used for qualitative identification and quality evaluation of C. militaris.
