Five New Sesquiterpenoids and a New Diterpenoid from Erigeron anmius (L. ) Pers. , Erigeron philadelphicus L. and Erigeron sumatrensis Retz

The aerial parts of Erigeron annum (L. ) Pers. , E. philadelphicus L. and E. sumatrensis Retz. (Compositae) have been investigated chemically. A new sesquiterpenoid, 6β, 14-epoxyeudesm-4(15)-en-1β-ol (1), and a new diterpenoid, philadelphinone (6), have been isolated from E. philadelphicus. Four new...

Summary:The aerial parts of Erigeron annum (L. ) Pers. , E. philadelphicus L. and E. sumatrensis Retz. (Compositae) have been investigated chemically. A new sesquiterpenoid, 6β, 14-epoxyeudesm-4(15)-en-1β-ol (1), and a new diterpenoid, philadelphinone (6), have been isolated from E. philadelphicus. Four new sesquiterpenoids, (7R*)opposit-4(15)-ene-1β, 7-diol (2), 11-methoxyopposit-4(15)-en-1β-ol (3), 15-methoxyisodauc-3-ene-1β, 5a-diol (4) and 10α-hydroxycadin-4-en-15-al (5), have been isolated from E. annuus. Compounds 2 and 4 were also isolated from E. sumatrensis. The structures of the new compounds were elucidated on the basis of their spectral data.
