Supercritical Extraction and Analysis of Cinnamaldehyde from Cinnamon Bark and Investigation of Effective Conditions in Comparison to Other Traditional Methods

Research shows that cinnamon essential oil (especially Cinnamaldehyde) can be effective on the treatment of diabetics. So the main purpose of this study was supercritical extraction and experimental investigation of Cinnamaldehyde from cinnamon bark. In this article, a comparison of traditional extraction methods versus the supercritical extraction of cinnamon essential oils was carried out. Then Cinnamaldehyde by using modified supercritical carbon dioxide with a fixed amount of methanol (1ml) was extracted and compared with Soxhlet extraction. Supercritical fluid extraction (SFE) with a static time of 20 minutes and the average particle size (0/674 mm) was used. The effects of variables on the process such as temperature (40- 80 ˚C), pressure (10-30Mpa), carbon dioxide flow rate (1/5 – 2/5 ml/min) and dynamic extraction time (40-120 min) were investigated on yield.
