title: Stereostructure of plagiochiline A and conversion of plagiochiline A and stearoylvelutinal into hot-tasting compounds by human saliva.
abstract: 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.
