title: Sesquiterpenoids from Magnolia grandiflora.
abstract: Three new sesquiterpenoids were obtained from the leaves of Magnolia grandiflora L. Their structures were determined as 6 alpha,11-dihydroxy-12,13-diacetoxyelem-1,3-diene, 4 alpha,6 alpha,10 alpha-trihydroxy-13-acetoxyguaia-11-ene, and 12,13-diacetoxyguaia-4 alpha,6 alpha,10 alpha,11-tetraol on the basis of spectral evidence. In addition, the known sesquiterpenoid magnograndiolide was also obtained.
