Serratene-type triterpenoids from Huperzia serrata.
Seven new and 15 known serratene-type triterpenoids were isolated from the whole plant of Huperzia serrata. The structures of these new triterpenoids were elucidated as 21alpha-hydroxyserrat-14-en-3beta-yl p-dihydrocoumarate (1), 21alpha-hydroxyserrat-14-en-3beta-yl dihydrocaffeate (2), 21alpha-hydroxyserrat-14-en-3beta-yl propanedioic acid monoester (3), 3alpha,21alpha-dihydroxyserrat-14-en-24-oic acid (4), 16-oxo-3alpha,21beta-dihydroxyserrat-14-en-24-al (5), 16-oxo-3alpha,21beta-dihydroxyserrat-14-en-24-oic acid (6), and 16-oxo-21beta-hydroxyserrat-14-en-3alpha-yl acetate (7), respectively, by means of spectroscopic analysis.
