Abstract:
Objective: To study the chemical constituents in the barks and leaves of Cinnamomum cassia.Methods: The crude extracts of the barks and leaves of Cinnamomum cassia were extracted by ethanol, the chemical constituents of the crude extracts were separated and purified by chromatographic methods and identified by spectroscopic analysis.Results: Five lignans were separated from the barks and two lignans were separated from the leaves of Cinnamomum cassia as follows: (7S,8R)-dihydrodehydrodiconiferyl alcohol 9'-O-β-D-apiofuranosyl-(1→6)-O-β-D-glucopyranoside (1), 1,2,3-propanetriol,1--3-methoxyphenyl-(1R,2R) (2), (6R,7R,8R)-7a-lyoniresinol (3), (6S,7R,8R)-7a-lyoniresinol (4), (6R,7S,8S)-7a-lyoniresinol (5),(+)-lariciresinol(6), (-)-4-epi-lyoniresinol (7).Conclusion: All the lignans are isolated from Cinnamomum cassia for the first time.
