Key Message

Variability is present in the seedling population of cinnamon for coumarin content and multi-season systematic selection could help in identification of low coumarin genotypes for future applications.

Abstract

True cinnamon has been used in the food and pharmaceutical industries since ages. Though produced mostly in the tropics, it has been quite popular in the tropical and temperate world equally. However, the world trade largely happens with different Cinnamomum species, which are known to contain much higher contents of coumarin (a potentially harmful compound) than the true cinnamon. Producing raw material with low coumarins could be a pragmatic step in assuring quality raw material entering the food and pharmaceutical chains. Effort was made to understand the variability among 24 accessions of true cinnamon for coumarin content over two years. Konkan Tej, a recommended variety for cultivation in the region, was used as a check for the study. Results revealed significant variability among the accessions for coumarin (below detectable limits to 270.192 mg/kg during first year; and below detectable to 398.215 during the second year of analysis). Pooled data analysis showed that seven accessions showed statistically lower coumarin content than the check (Konkan Tej). Such accessions could be promoted on large scale to obtain raw material containing naturally lower contents of coumarin. The study emphasizes upon the need of multi-season evaluation for coumarin content in cinnamon, as considerable variability exists for it. This would help the researchers in identifying the desirable genotypes for quality raw material production of this industrially important crop.
