Studying chemical constituents of Nelumbo nucifera plants, cultivated in HaNoi

Tóm tắt

Nelumbo nucifera flower oil, collected by stream distillation, contained mainly pentadecane (36.49%), a-terpineol (11.88%)… From the ethanol extracts of Nelumbo nucifera leaves dried powders were isolated and by various spectral methods structurally elucidated four compounds: didecylamine, b-sitosterol, hexadecanamide and nuciferine. Nuciferine, a main aporphine-type alkaloid of Nelumbo nucifera, showed some activities towards E.coli, P.aeruginosa, B.substilis, S.aureus and C.albicans  (IC₅₀> 128 mg/ml).
