摘　　要：This paper deals with the study on the essential oil of zingiber corallium hance obtained by supercritical CO2 extraction and steam distillation.The comparison of technological process characteristics and chemical composition of these essential oils obtained by supercritical CO2 extraction and steam distillation has been done.Also we have done some experiments on antifungus and antibacterium activities of these oils.For the extraction process of the essential oil of zingiber corallium hance,supercritical CO2 extraction is better than that by steam distillation.The inhibitory activities of the essential oil extracted by both methods are the same.It shows that supercritical CO2 extraction can be as a new technological process used in the extraction for exxential oil of herb.This paper deals with the study on the essential oil of zingiber corallium hance obtained by supercritical CO2 extraction and steam distillation.The comparison of technological process characteristics and chemical composition of these essential oils obtained by supercritical CO2 extraction and steam distillation has been done.Also we have done some experiments on antifungus and antibacterium activities of these oils.For the extraction process of the essential oil of zingiber corallium hance,supercritical CO2 extraction is better than that by steam distillation.The inhibitory activities of the essential oil extracted by both methods are the same.It shows that supercritical CO2 extraction can be as a new technological process used in the extraction for exxential oil of herb.
