Chemical constituents of Cyanotis arachnoidea

    Abstract
  • AimTo investigate the chemical constituents of Cyanotis arachnoidea.MethodsBy using chromatographic methods for separation and combination with spectral analysis, their chemical structures were determined. ResultsSix compounds were identified as ajugasterone C-20,22-acetonide (1), 20-hydroxyecdysone-20,22-acetonide (2), 22-oxo-ajugasterone C (3), 22-oxo-20-hydroxyecdysone (4), β-sitosterol (5), daucosterol (6).ConclusionCompound 3 is a new compound, 4 was a new natural compound.
