| 摘要: |
| 通过对采收后的黄花蒿植株进行适当的处理及干燥温度和贮藏时间对比试验,采用HPLC法测定,探讨提高青蒿素含量的加工新方法。结果表明:整株立式阴晾一定时间后晒干的处理随着阴晾时间的增加青蒿素含量呈抛物线状变化,4～5 d最高,达显著水平,之后逐渐下降; 随着干燥温度的升高青蒿素含量呈下降趋势,40 ℃时叶片青蒿素含量较高; 随着贮藏时间的延长青蒿素含量逐渐下降,贮藏100 d后下降明显。采收后整株立式阴晾4～5 d后再晒干方法能提高黄花蒿叶片的青蒿素含量。40 ℃的干燥温度能使叶片中青蒿素含量损耗较少。黄花蒿叶片的保质贮藏时间约90 d。 |

| Abstract: |
| The new method which may improve the artemesinin content were determined by HPLC through the contrast test on processing the post-harvest plant by suitable treatment and drying temperature and storage time. The result showed that:firstly,with increasing airing time in the shade,the artemesinin content showed parabolic change after the whole were dried and processed,4-5 d highest,to significant level,and then gradually decreased; Secondly,with the drying temperature increased,artemesinin content showed a downward trend,artemesinin content of leaves was higher at 40 ℃; Thirdly,with prolonging storage time,artemesinin content decreased gradually,and decreased significantly after 100 d.The result showed that: the whole plant were verticaly aired 4-5 d and then dried in sun after harvesting,which could increase the artemesinin content of leaves. The artemesinin content of leaves had less loss under dry temperature of 40 ℃. The quality preservation of leaves was about 90 d. |
