[Multi-component of Cibotium baronetz decoction pieces via 1H-NMR spectroscopic analysis].

OBJECTIVE: 1H-NMR technology was carried out to investigate the chemical difference between 30 batches of Cibotium baronetz decoction pieces and look for new method for quality control of C. baronetz decoction pieces.

METHOD: Six hundreds MHz H-NMR spectroscopy and principle component analysis (PCA) were used to discriminate between 30 batches of commercially available cibotium samples based on multi-component metabolite profiles.

RESULT: Saccharide is the principle component of C. baronetz decoction pieces, and steroid and triterpene were the discriminately chemical component. Protocatechuic acid, protocatechuic aldehyde, cibotiumbaroside A, cibotiumbaroside B and 4-O-caffeoyl-D-glucoside could be used as the marker for controlling the quality of commercial C. baronetz decoction pieces.

CONCLUSION: Pattern-recognition techniques applied to proton nuclear magnetic resonance (1H-NMR) spectra of 80% methanol extraction of C. baronetz could correctly discriminate not only the quality, but also the chemical component for batches of commercial C. baronetz decoction pieces.
