不同产地与类型及采收方法对黄花蒿中青蒿素含量的影响

以来源于重庆、广西、湖南、广东、江苏、陕西等省区的72分种质资源为试验材料,研究不同产地与类型及采收方法对黄花蒿中青蒿素含量的影响,为良种的选育和药材的采收提供科学的依据。结果表明:(1)早熟型与中、晚熟型青蒿素含量的差异显著,其顺序为:中熟型>晚熟型>早熟型;(2)在同一管理条件下不同茎秆颜色的青蒿素含量之间差异显著,其顺序为:白杆型>黄绿秆型>紫秆型>绿秆型;(3)不同产地的黄花蒿青蒿素含量动态变化规律一致,青蒿素含量最高时期为孕蕾期,是最佳采收期;(4)不同部位之间青蒿素含量差异显著,以叶片的青蒿素含量最高。

Effect of different areas,types,harvest methods on artemisinin content of Artemisia annua

72 wild or cultivated Artemisia annua germplasms from Chongqing,Guangxi and Hunan provinces etc. were studied as experimental material. The results were as follows:(1)artemisinin content was significantly different among Early-maturing,Middle-maturing and Late-maturing. They were arranged in the following order in terms of their artemisinin content:Middle-maturing＞Late-maturing＞Early-maturing;(2)Different A.annua had different morphology even if they were planted under the same condition. Artemisinin content was significant differece in different colour stems,the sequence ranked:white stem＞yellow and green stem＞purple stem＞green stem;(3)Dynamic rule of artemisinin content was consistent in different germplasms. The highest content of artemisinin was pre-flowering stage;(4)artemisinin content was significant difference in different parts,the highest content of artemisinin was in the leaves.
