침향 추출물의 면역조절 및 생리활성 분석

Abstract

Objectives : Aquilaria crassna is a traditional herbal medicine, which is used to treat allergies, diabetes, neurological diseases. Recently, Aquilaria crassna extracts have been reported in anti-bacterial and anti-inflammatory activities. In this study, various solvents fraction of Aquilaria crassna were investigated on various physiological activities. Methods : According to the polarity, the solvents fraction of Aquilaria crassna were confirmed through TLC, and the activities of the extracts were confirmed in anti-diabetes, anti-obesity, whitening, anti-gout, and anti-inflammation. Results : TLC results showed that ACM and ACM/E have similar patterns and most of the components were transferred to ACM/E. Treatment with ACM and ACM/E fraction were significantly decreased the generation of NO in lipopolysaccharide (LPS)-stimulated macrophage cells. Analysis of biological activities such as α-glucosidase, protein tyrosine phosphatase (PTP1B), tyrosinase, xanthine oxidase (XO) and pancreatic lipase inhibition, showed that ACM and ACM/E have more inhibitory effects than other fractions. Conclusions : Therefore, the results of the present study clearly demonstrate that Aquilaria crassna and its constituents might be beneficial in the prevention or treatment of immune-regulating effects.
