Cytotoxic polyhydroxy serratene triterpenoids from Lycopodium complanatum

Phytochemical investigation of the 70% aqueous EtOH extract of Lycopodium complanatum led to six new polyhydroxy serratene triterpenoids (serrat A-F, 1–6), along with a known analogue (7). Their structures and configurations were elucidated by data analysis of HRESIMS, 1D and 2D NMR, in combination with comparisons of reported experimental spectroscopic data. All the isolates were evaluated cytotoxic activities against HepG2 cells, MCF-7 cells...
