N2 - The polyacetylene contents of one form of the species Dahlia coccinea Cav. var. coccinea and also of a horticultural form derived from the same species have been examined. The nineteen polyacetylenes detected comprised eight C 13, eight C14, and three C17 compounds. Five of them were previously unknown; their isolation, characterisation, and structure determination are described. They are the C14 2,3-disbustituted tetrahydroprans CH3·[C≡C]3·CH= tCH·CH·CH(OR)·[CH2] 2·CH2·O and CH3·CH= tCH·[C≡C]2·CH=tCH· CH·CH(OR)·[CH2]3·O (R = H or Ac), and the C17 acetate CH3·CH= tCH·[C≡C]2·[CH=ttCH] 2·CH(OAc)·[CH2]3·CH= CH2.
