Screening of Effective Extraction Conditions for Increasing Antioxidant Activities of Licorice Extracts from Various Countries of Origin

Abstract: In this work, licorice extracts were prepared using various extraction conditions such as extraction solvent, temperature, and time from Glycyrrhiza uralensis (G. uralensis) produced in Korea and China and Glycyrrhiza glabra (G. glabra) in Uzbekistan. The optimum extraction condition was selected from the extraction yields and antioxidative activities of extracts. Korea licorice extracts showed the highest free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity (46.05%) under the extraction cond… Show more

“…Therefore, ethanol as an organic solvent was considered as the most suitable solvent during the extraction of bioactive molecules such as antiviral components from licorice. Similarly, Kim et al (2006) and Ha et al (2013) reported that antioxidant activity of licorice extracts was increased with increase in ethanol concentration.…”

“…감초(Glycyrrhiza, licorice)는 콩과 식물(Legumiosae)에 속하 는 다년생 초본으로, 한국, 중국 및 일본에서 한약재로써 널리 이용되고 있는 약용식물이다. 현재 우리나라에서 약용으로 유통 되는 감초의 대부분은 만주감초(Glycyrrhiza uralnesis)로 주로 식품분야에서 사용되는 것으로 알려져 있고, 최근 유럽감초(G. glabra)의 수입량도 증가하고 있다 [7]. 감초에 관한 국내•외 연 구로는 항산화, 항염증, 항균 및 항당뇨 등의 생리활성이 보고 되었다 [8][9][10][11].…”

“…감초에 관한 국내•외 연 구로는 항산화, 항염증, 항균 및 항당뇨 등의 생리활성이 보고 되었다 [8][9][10][11]. 감초는 단맛을 내는 주요성분인 glycyrrhizic acid 등 의 glycyrrhizin 계열 화합물과 liquiritin, liquiritigenin, isoliquiritigenin 등의 flavonoid 계열 화합물을 포함하여, 항산화 활성이 우수한 성분을 함유하는 것으로 알려져 있다 [7,12]. 신원감(Shinwongam, SW)은 G. uralensis와 G. glabra를 교배시켜 재배한 국내산 신 품종 감초로 근장, 근경, 지근수가 많아 G. uralensis보다 한국 토양에 적응력이 높은 것으로 알려져 있다 [13].…”
