Qualitative identification of the 6-gingerol standard. (a) Infra-red spectrum of the 6-gingerol standard, (b) electrospray ionization-mass spectrometry of the 6-gingerol standard, (c) ultraviolet spectrum of the 6-gingerol standard, (d) 1hydrogen-nuclear magnetic resonance spectrum of the 6-gingerol standard, (e) 13carbon-nuclear magnetic resonance spectrum of the 6-gingerol standard. The 6-gingerol standard obtained from Zhongxin was validated to be 6-gingerol by serial qualitative analysis
