ACETYLENES FROM THE ROOTS OF SOLIDAGO SPECIES

Article abstract of DOI:10.1016/0031-9422(92)80433-F

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.
