title: Amplectol: A Novel Acetylenic Thiophene Derivative from Blumea amplectens var. arenaria.
abstract: The aerial parts of BLUMEA AMPLECTENS var. ARENARIA afforded taraxasteryl acetate, dihydrosterculic acid, the sesquiterpene ferutinin, and the acetylenic thiophene diol, 3,4-dihydroxy-8-[5'-methylthiophen-2'-yl]-1, 5-octadien-7-yne, named as amplectol. Thestructures were elucidated by spectroscopic methods. A biogenetic pathway for the formation of amplectol in the plant is also suggested.
