Two triterpenoids isolated from ethyl acetat fraction of Huperzia Serrata (thunb.) Trevis

To extract, isolate, determine the structure of compounds from Huperzia serrata (Thunb.) Trevis. Subjects and methods: The samples were collected in Tamdao National Park. The structure of substances was determined by spectral methods. Results and conclusions: 2 compounds of terpenoid group were isolated, namely: 3β, 21β, 29-trihydroxyserrat-14-en-24-oic acid-3β-yl- (7’-hydroxycinnamate); 16-oxo-3α-hydroxyserrat-14-en-21β-ol, the substances were confirmed by the structure of NMR, MS, HMBC, HSQC.
