Abstract

The content of atropine and scopolamine is known to vary with ontogeny and plant organs selected which makes it necessary to define the optimal stage for harvesting of each plant organ. The present study aims at investigating the effect of ontogeny on the accumulation of atropine and scopolamine in the leaves, stems, roots, flowers and fruits of the Solanaceae plants Burgmansia suaveolens Bercht. & J.Presl, Datura stramonium L., D. arborea L., D. inoxia Mill. and Hyoscyamus albus L. Results showed that the highest content of atropine and scopolamine was observed during the flowering stage of most organs. H. albus L. leaves collected during flowering stage exhibited the highest content of atropine (746.66 ug/g) followed by the pre-flowering leaves of D. stramonium L. and the flowering stage stems of H. albus L. while D. inoxia Mill. pre-flowering leaves and flowering stems had significantly higher content of scopolamine among all the tested extracts with a concentration of 555.04 ug/g and 244.26 ug/g, respectively.

摘要

已知阿托品和东莨菪碱的含量随个体发育和选择的植物器官而变化，这使得有必要确定每个植物器官收获的最佳阶段。本研究旨在研究个体发育对茄科植物Burgmansia suaveolens Bercht的叶、茎、根、花和果实中阿托品和东莨菪碱积累的影响。& J.Presl,曼陀罗L. , D. arborea L., D. inoxia Mill。和天仙子黄鳝L.结果表明，在大多数器官的开花期，观察阿托品和东莨菪碱的含量最高。H.阿不思开花阶段期间收集的叶子L.表现出阿托品，随后的预开花叶含量最高（746.66微克/克）D.曼陀罗L.和的开花期茎H.球菌L.而D. inoxia轧机。花前叶和花茎在所有测试提取物中东莨菪碱的含量显着较高，浓度分别为555.04 ug/g和244.26 ug/g。
