|Section2= |Section3= }} Syringaldehyde is an organic compound that occurs in trace amounts widely in nature. Some species of insects use syringaldehyde in their chemical communication systems. ''Scolytus multistriatus'' uses it as a signal to find a host tree during oviposition.〔Vanillin and Syringaldehyde as Attractants for Scolytus multistriatus (Coleoptera: Scolytidae). Meyer H.J. and Norris D.M., Annals of the Entomological Society of America, 17 July 1967, Volume 60, Number 4, pages 858-859, ((abstract ))〕 Because it contains many functional groups, it can be classified in many ways - aromatic, aldehyde, phenol. It is a colorless solid (impure samples appear yellowish) that is soluble in alcohol and polar organic solvents. Its refractive index is 1.53. == Natural sources == Syringaldehyde can be found naturally in the wood of spruce and maple trees. Syringaldehyde is also formed in oak barrels and extracted into whisky, which it gives spicy, smoky, hot and smoldering wood aromas.〔http://www.liquorpress.com/2011/04/06/aromatic-substances-of-whisky-syringaldehyde-and-syringa-acid/〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「syringaldehyde」の詳細全文を読む スポンサード リンク
