- 中文摘要: By means of spectroscopic analysis, X-ray crystallography and chemical correlation the heartwood of Taiwan hemlock was found to contain compounds of sterols, carboxylic acids, 13-epimanool, o-methoxyphenolics, coniferaldehyde, benzofuranoid neolignan, .alpha.-conidendrin, tsugacetal, isolariciresinol, secoisolariciresinol, matairesinol, hydroxymatairesinol and oxomatairesinol. Among them (+)-tsugacetal is a novel lignan acetal having an .alpha.-conidendrin related structure with the acetal methoxy group at the .beta.-position.
