Studies on Chemical Compositions of Podocarpus neriifolius D. Don

Xu Li-zhen,Chen Zhen and Sun Nan-jun   

Abstract: Eleven compositions isolated from Podocarpus neriifolius D. Don were identified as n-C34H69OH (1), β-sitosteryl stearate (2), β-sitosterol (3), sciadopitysin (8), podocarpusflavone B (12), robustaflavone-7"-methyl ether (13), podocarpusflavone A(14), robustaflavone (15), p-hydroxyl benzoic acid (16), 2"-O-rhamnosylscopariu (23), 2"-O-rhamnosyl vitexin (24) on the basis of physical constants and spectral data. Among them, compound 8, 13 and 15 were found from the species for the first time. Compound 113 and 24 were reported from Podocarpaceae for the first time. The ethanol extract of P.neriitolius showed obvious cytotoxicity against A-549 and HT-29.

Key words: Podocarpus neriifolius D.Don, Sciadopitysin, Podocarpusflavone A and B, Robustaflavone-7'-methyl ether, Robustaflavone, 2"-O-rhamnosylvitexin, 2"-O-rhamnosylscoparin
