Roots of six Solidago species were examined for their content of acetylenes.The E and Z isomer of dehydromatricaria ester, (Z,Z)-matricaria ester, (Z)-dehydromatricaria lactone and a C16-acetylene were isolated and identified.The Z and E isomer of dehydromatricaria lactone were furthermore produced by oxidation of 2,4-hexadiynyliden-1,6-dioxaspiro-<4.4>nona-2,8-dien-4-ol with activated MnO2. Key Word Index - Solidago species; Astereae; Compositae; roots; acetylenes; spiroacetal enol ethers; oxidation; chemotaxonomy.
