The stereostructure of plagiochiline A (1) isolated from the liverwort Plagiochila fruticosa has been established by X-ray crystallographic analysis. Plagiochiline A was converted into plagiochilal B (2) and furanoplagiochilal (3) by human saliva, and stearoylvelutinal (4) isolated from the fungus Lactarius vellerus was converted into velleral (5), also by human saliva.
通过 X 射线晶体学分析,确定了从肝草 Plagiochila fruticosa 中分离出来的 plagiochiline A(1)的立体结构。Plagiochiline A 在人体唾液的作用下转化为 plagiochilal B (2) 和 furanoplagiochilal (3),而从 Lactarius vellerus 真菌中分离出来的硬脂酰绒毛醛 (4) 也在人体唾液的作用下转化为 velleral (5)。
