摘 要:为进一步探讨5-羟甲基-2-糠醛(5-HMF)在生脉散各配伍组中的含量变化,用高效液相色谱法测定了不同配伍组中5-HMF的含量,并测定了不同煎煮时间,煎煮次数及不同比例的麦冬与五味子配伍对5-HMF含量的影响。结果表明5-HMF是麦冬与五味子共煎过程中生成的,含量随麦冬的增加而增加,以煎煮1.5h为最高,且前2次煎煮即提取完全。The content changes of 5hydroxymethy12furaldehyde(5HMF),a new compound reported in the previous paper,in eight prescriptions of different composition were further determined by HPLC with a view to find the chemical dynamic changes and compatibility of medicines.The contents of 5HMF in different combinations of Radix Ophiopogonis and Fructus Schisandrae,different boiling times and boiling frequency were examined. The results indicated that 5HMF was produced in the boiling process of Radix Ophiopogonis and Fructus Schisandra combined.The contents of 5HMF would increase with the increase of Radix Ophiopogonis amount,reaching the highest value after 1.5h boiling and two times of boiling.
