Abstract

Objectives: To investigate factors affecting the enrichment of 6-shogaol (6-SHO) from ginger extract using the microwave-assisted method. Methods: Ginger extract was enriched in 6-SHO using microwave irradiation. The investigated  factors included type and concentration of heating solvent, solid-to-solvent ratio, type and concentration of catalytic acid, treatment time, and microwave power. Results: The optimal conditions for 6-SHO enrichment in ginger extract were identified as follows: 90% ethanol as the heating solvent, a solid-to-solvent ratio of 1/15 (w/v), 1.2M acetic acid as the catalytic agent, treatment time of 15 minutes, and a microwave power of 200W. Conclusion: The study successfully investigated several factors influencing the microwave-assisted enrichment of 6-SHO, thereby, establishing the process for 6-SHO enrichment from ginger extract. Enriched ginger extract reached a 6-SHO content of 30.814 mg/g, representing a 116-fold increase compared to the initial dried ginger.
