Abstract

The root of Gentiana scabra is commonly known as Longdan in Chinese herbal medicines and has been used in the treatment of inflammation, anorexia, indigestion and gastric infections for over 2000 years. High market demand had made G. scabra (GS) plants not to be the only source of Longdan in China, other Gentiana spp., G. triflora, G. manshurica and G. rigescens, were also recognized as Longdan in China now. In this study, we identified three Taiwan-specific Gentiana spp., G. davidii var. formosana (GDF) and G. arisanensis (GA) and G. scabrida var. punctulata (GSP) that are phylogenetically different from GS (main source of Longdan). However, the active compounds of Longdan, gentiopicroside and swertiamari, were found in GSP and GDF showed higher antioxidant ability and free radical scavenging activities than Chinese Longdan. This discovery might explore the medicinal potential of GDF. Meanwhile, another Taiwan-specific Gentiana spp., GSP, was found to have the strongest antioxidant ability and free radical scavenging activities which might suggest a possible use of GSP as a source of natural antioxidant agents for industrial purpose. The finding of this study indicated that ITS analysis can be used to identify Taiwan-specific ...Continue Reading
