Abstract

Knowledge about members of the flowering plant family Clusiaceae occurring in the tropical mountain regions of the world is limited, in part due to endemism and restricted distributions. High altitude vegetation habitats (Páramos) in Central and South America are home to numerous native Hypericum species. Information related to the phytochemistry of páramo Hypericum, as well as ecological factors with the potential to influence chemical defenses in these plants, is briefly reviewed. Results of the phytochemical analysis of Hypericum irazuense, a species collected in the páramo of the Cordillera de Talamanca in Costa Rica, are presented. Lastly, guidelines for the viable and sustainable collections of plant material, to facilitate future investigations of these interesting plants, are given.

摘要

关于世界热带山区开花植物科藤黄科植物的知识有限,部分原因是其特有性和分布范围受限。中美洲和南美洲的高海拔植被栖息地(帕拉莫)是众多本土金丝桃属物种的家园。本文简要回顾了与帕拉莫金丝桃属植物的植物化学相关的信息,以及可能影响这些植物化学防御的生态因素。文中呈现了对在哥斯达黎加塔拉曼卡山脉帕拉莫采集的伊拉苏金丝桃属植物的植物化学分析结果。最后,给出了关于植物材料可行且可持续采集的指南,以促进对这些有趣植物的未来研究。
