Abstract

Aim: To differentiate the genuine cassia bark from its substitutes and adulterants. Methods: Six components, phenylpropyl acetate, cinnamyl acetate, cinnamaldehyde, cinnamyl alcohol, coumarin, and cinnamic acid were used as characteristic markers, and an optimized TLC method was developed. Results: The TLC profile of cassia bark is similar to its closely related variety Cinnamomum cassia Presl var. macrophyllum Chu but significantly different from other six Cinnamomum species. High content of phenylpropyl acetate, cinnamaldehyde, and coumarin was found in superior commercial grade debarked cortex. Conclusion: The developed TLC method can be used to differentiate the genuine cassia bark from its substitutes and adulterants.
