已知苔藓中含有某种生理活性物质。但直至最近,由于分析技术的进展,才开始其化学研究。本文叙述作者的部分研究结果以及最近文献上发表的重要结果。在加拿大及欧洲,已知细鳞苔类可诱发接触性皮炎。据报道,即使保存了半个世纪的细鳞苔类(皱萼苔,Ptychanthus striatus)的标本仍可引起接触性皮疹。作者发现,这 Moss is known to contain some physiologically active substance. However, until recently, chemical research began as a result of advances in analytical techniques. This article describes some of the author’s findings as well as the most recent published literature. In Canada and Europe it is known that Sphagnum can induce contact dermatitis. It has been reported that even specimens preserved for half a century of Prynidus species (Ptychanthus striatus) can cause contact rashes. The authors found that this
