title: Tubiferic acid, a new 9,10-secocycloartane triterpenoid acid isolated from the myxomycete Tubulifera arachnoidea.
abstract: Tubiferic acid (1), a new triterpenoid acid having a 2,6-dimethyl-4,5-dihydroxy-2-hexenoic acid moiety as a side chain, was isolated from field-collected fruit bodies of the myxomycete Tubulifera arachnoidea, and its structure was elucidated by spectral data. Tubiferic acid (1) had the same unique 9,10-secocycloartane carbon skeleton as tubiferal A (2).
