摘要: 基于青蒿酸重要的药用和开发价值,采用溶剂法、吸附分离法从黄花蒿植物制备青蒿酸,采用光谱、质谱和熔点法表征青蒿酸晶体,采用HPLC法分析其生物稳定性。通过制备工艺获得纯度为96%的青蒿酸结晶,产率为61.7%。4 ℃、室温、60 ℃以及自然光照条件下保存30 d青蒿酸具有较好的生物稳定性;植物体内外青蒿酸均能稳定保存一年,含量基本不变。紫外光照条件下青蒿酸易光解,6 h后基本检测不出青蒿酸。通过制备工艺获得高纯度的青蒿酸结晶,青蒿酸对温度和自然光照较为稳定,在植物体内外均可保存一年。紫外光对青蒿酸具有较强的破坏作用。

Abstract: In this paper,the preparation of artemisinic acid from Artemisia annua L.was investigated and its biological stability was explored.Liquidliquid extraction method and adsorptive separation method were used to prepare artemisinic acid from A.annua,and spectroscopic,mass spectrometry and melting point method were adopted to characterize artemisinic acid crystals.The biological stability of artemisinic acid was analyzed using thin layer chromatography (TLC) and high performance liquid chromatography (HPLC).Artemisinic acid crystal was successfully obtained by liquidliquid extraction method and Adsorptive separation method,and the yield of product reached to 61.7% and the purity of product was higher than 96%.Artemisinic acid was very stable under the conditions of 4 oC,room temperature,60 oC and natural lighting for 30 d.Furthermore,it was stably preserved in plant for a year with its content maintained at the same level.The structure of product was badly destructed by UV light,and it was not detected after lighting for 6 h.In conclusion,high purity of artemisinic acid could be obtained by the developed preparation methods.It was more stable at the conditions of natural light and temperature,and the artemisinic acid could save one year in vivo and in vitro. However,UV light strongly destroy artemisinic acid.
