摘要: 为了研究油菜蜂花粉中核苷类成分的组成,本实验采用15%乙醇进行超声提取,结合薄层色谱法(thin layer chromatography,TLC )分析(展开剂为氯仿-甲醇-氨水,体积比为6.5:8.0:1.5),再经D101大孔吸附树脂柱层析(洗脱剂为5%乙醇)、水饱和正丁醇萃取及高效液相色谱法(high-performance liquid chromatography, HPLC)分离纯化,最终分离得到单一化合物,通过液相色谱-四极杆-飞行时间串联质谱法(liquid chromatography - quadrupole - time of flight mass spectrometer,LC-Q-TOF)对其相对分子质量、不饱和度、同位素匹配度、相似度进行分析,通过HPLC法比较样品与标准品的保留时间、紫外光谱图比对,确认该化合物为腺嘌呤(adenine)。

Abstract: In order to explore the nucleoside composition of rape bee pollen, the sample was subjected to extraction with 15% aqueous ethanol under the assistance of ultrasonic, TLC analysis using chloroform-methanol-ammonia (6.5:8.0:1.5, V/V) as the development solvent, chromatographic separation on D101 type macroporous adsorption resin column using 5% aqueous ethanol as the elution solvent, water saturated butanol extraction and high-performance liquid chromatographic (HPLC) purification and as a result, a single compound was obtained. The compound was identified as adenine by liquid chromatography-quadrupole-time of flight mass spectrometer (LC-Q-TOF) according to the data of accurate mass, double bond equivalent (DBE), spacing match and similarity score and by comparison of its retention time and UV spectrum with those of the reference substance.
