摘要
目的检测不同烘干温度对秦艽中龙胆苦苷含量的影响。方法采用HPLC测定在不同烘干温度下干燥的秦艽品中龙胆苦苷的含量。结果在20℃,40％,60℃,80℃,100℃烘干秦艽时, 随温度升高,秦艽中龙胆苦苷的含量逐渐升高,在100℃时达到最高,其含量为8．55％。在100％℃, 120℃,140℃,160℃,180℃,200℃时,龙胆苦苷的含量逐渐下降,在200℃时含量降至最低,其含量为3．27％。结论秦艽药材最佳的烘干温度为100℃,在此温度下烘干的秦艽药材中龙胆苦苷的含量最高,且干燥时间较短。
Aim To determine the best baking temperature and the corresponding time on Gentiana macrophylla. Methods Using the HPLC to detect the gentiopicroside content at different baking temperature as an index, the suitable baking temperature and the corresponding time were investigated. Results When the baking temperature is at 20℃, 40℃, 60℃, 80℃, 100℃, the content of gentiopicroside is accordingly to high and the highest is 8.55%, on the other hand the content is lower from 120℃ to 200℃ and its lowest content is 3.27%. Conclusion The gentiopicroside content is the hightest at the baking temperature of 100℃ and the the baking time is short.
