| cinnamomum zeylanicum leaf oil | |||
| The seasonal variation in the composition of cinnamon leaf oil produced from leaves harvested at different times of the year was studied by Kaul et al. (1996). They found that oil produced from leaves harvested either in the summer or in the winter possessed comparable chemical compositions, whereas an oil produced from leaves harvested in the rainy season had a reduced level of eugenol and an increased level of eugenyl acetate (Table VIII). Note: this page will only include the summer harvest. | |||
