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 14β,15β-epoxy-3β-hydroxyserratan-21β-ol (1), 14β,15β-epoxy-3β-hydroxyserratan-21α-ol (2), and 14β,15β-epoxy-3β-hydroxyserratan-21α-ol-3β-O-acetate (3), respectively, on the basis of spectral data and for 1 by single-crystal X-ray analysis.
