Objective:To study the tritepenoid constituents from air-dried whole plant of Lycopodium japonicum
Method:The chemical constituents were isolated by normal-phase silica gel column chromatography from the n-butanol extract.Their structure were identified by1H-NMR
13C-NMR
MS.Result:Seven triterpoinds were purified and identified as serrat-14-en-3β
21α-diol(1)
serrat-14-en-3β
21β-diol(2)
lycoclaninol(3)
lycoclavanol(4)
α-onocerin(5)
16-Oxo-3α-hydroxyserrat-14-en-21α-ol(6)
daucosterol(7).Conclution:Among these compounds 16-Oxo-3α-hydroxyserrat-14-en-21α-ol(6)
daucosterol(7)were isolated from the plants of Lycopodium japonicum for the first time.
