将实验所得嘌呤化合物溶解于质量浓度为1％的氢氧化钠水溶液中，通过测量抑菌圈直径的大小来测试了所有所得嘌呤衍生物的抑菌活性。

Furoic acid was synthesied by catalytic oxidation in the mimic enzyme microreactor, which was constructed by strong stirring a non homogeneous phase system of organic reagent and water using β cyclodextrin derivative as an imitating enzyme. This method is easy to handle and more effective than the corresponding reaction in homogeneous phase.

在水与有机试剂组成的非均相体系中，用β环糊精(β cyclodextrin ，缩写：β CD)衍生物模拟生物酶，以强力搅拌下分散在有机溶剂中的小水珠作为微型反应器进行糠醛催化氧化为糠酸的反应，停止搅拌后体系立即分层，产物在有机相，残留的原料和模拟酶在水相。

Then the fiber was transferred to a 4 mL vial which was filled with 100 μL of trifluoroacetic anhydride and stood 30 sec for headspace extraction. Afterward the fiber was transferred again to another blank 4 mL vial and stood 10 min for on-fiber derivatization before the analysis with GC/MS. The absorption-time profiles for both furoic acid and creatinine were examined.
