摘要: 本项研究测定了三种虫草(江西虫草、古尼虫草、戴氏虫草)发酵液与菌丝体中核苷类化合物的含量,并建立了定量分析的方法体系。其中,采用液体发酵的方法获得虫草菌丝体及其发酵液,应用超声破碎法提取虫草菌丝体中的核苷类化合物,最后应用高效液相色谱法二极管阵列检测器进行色谱分析,并以保留时间和吸收光谱双指标作为定性依据。实验取得了预期结果:优化了5种核苷化合物:腺苷、虫草素、尿苷、肌苷、鸟苷的色谱分离条件,分析了3种虫草中核苷类化合物的含量,精密度、稳定性、重现性和回收率实验表明这一方法可高效地定量分析虫草中的核苷类化合物。实验表明,HPLC-DAD法对虫草中的核苷类化合物的定量分析是一种有效的方法,该方法可快速准确地检测虫草有效成分的含量,本研究同时测定了胞外部分的化合物含量,系首次对这三种虫草细胞内外成分同时进行测定,对虫草的品质评价体系及其质量控制标准的建立具有重要意义。

Abstract: Five nucleosides(adenosine,cordycepin,uridine,inosine and guanosine)in three cordyceps(Cordyceps jiangxines, Cordyceps gunni, Cordyceps taii) were quantified using a developed high-performance liquid chromatography-diode array detector(HPLC-DAD)method.The mycelium and fermentation broth was obtained by the submerged cultivation.The nucleosides compoundswas extracted through ultrasonic fracture method.HPLC-DAD was applied for the quantitative analysis with retention time andabsorption spectrum adopted as qualitative evidences.The chromatographic separation conditions were optimized.The precision, stability, reproducibility and recovery were good which indicated the developed HPLC-DAD was valid for the quantification ofnucleosides.This was the first report of determining nucleosides contents in both intracellular and extracellular parts of three cordyceps.

Key words: Cordyceps, cultivation, mycelium, nucleosides, high-performance liquid chromatography, quantitative determination
