title: Highly oxygenated bisabolenes and an acetylene from Matricaria aurea.
abstract: Reinvestigation of the aerial parts of Matricaria aurea led to the isolation of three new bisabolenes and a new acetylene. The structures of the four compounds, namely (1R*,2R*,3R*,6R*,7R*)1,2,3,6,7- pentahydroxy-bisabol-10(11)-ene, (1R*,2R*,3R*,6R*,7R*)1,2,3,6,7-pentahydroxy-1-acetoxy-bisabol-10(1 1)-ene, (1R*,2R*,3R*,6R*,7R*)1,2,3,6,7-pentahydroxy-2-acetoxy-bisabol-10(1 1)-ene and (3S*,4S*,5R*)-(E)-3,4-dihydroxy-2-(hexa-2,4-diynyliden)-1,6- dioxaspiro-(4,5)decane, were deduced from the high field NMR studies.
