The Process Optimization Of Microwave Assisted Extraction On Cinnamomum Verum J. Presl. Extraction Yield And Comparative Of Chemical Compositions To Supercritical Fluid Extraction And Hydrodistillation

Abstract

n this present work, the optimization of microwave assisted extraction (MAE) for cinnamon (Cinnamomum
verum J.Presl.) was investigated to compare the extraction yields and chemical compositions with
hydrodistillation (HD) and supercritical fluid extraction (SFE). The effects of different parameters (microwave
power, extraction time and liquid to solid ratio) were investigated to obtain the optimum yield from MAE.
Response surface method (RSM) using Box-Behnken design (BBD) was deployed for the design of experiment
and optimization for MAE. The chemical compositions of cinnamon essential oils were analyzed by gas
chromatography-mass spectrometry (GC-MS). From the experimental result, the extraction yields of HD, MAE
and SFE were 2.13%, 2.86% and 6.83% respectively. However, MAE shown better result on extraction time than
HD and SFE. From RSM result, the highest yield of MAE was obtained by microwave power (662 W), extraction
time (36.8 min) and solid to liquid ratio (100g/513mL). The results from GC-MS presented that MAE was shown
better result on many terpene contents than HD and SFE. Cinnamaldehyde and cinnamyl acetate were detected
from MAE higher than SFE but lower than HD. However, methoxycinnamaldehyde was detected from MAE
higher than HD and SFE significantly.
