title: New epoxyserratanes from Huperzia serrata.
abstract: Three new serratane-type epoxytriterpenoids were isolated from the whole plant of Huperzia serrata. The structures of these new compounds were characterized as 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21 beta-ol (1), 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol (2), and 14 beta,15 beta-epoxy-3 beta-hydroxyserratan-21alpha-ol-3 beta-O-acetate (3), respectively, on the basis of spectral data and for 1 by single-crystal X-ray analysis.
