Typification of Glycine tomentella (Fabaceae: Phaseoleae) with comments on its internal groups

The legume Glycine tomentella had not been typified according to the rules of nomenclature for many years after it was described. While typification was attempted rather recently, the designated type material is currently missing. An appropriate replacement type is designated herein. Furthermore, the presence of intersterile, morphologically and molecularly diverged groups within the G. tomentella polyploid complex warrants an historical review and current perspective. The type material of this mainly Australian species is identified as belonging to a polyploid genome group that is found in Taiwan.

Antioxidant and Antityrosinase Activity ofFlemingia macrophyllaandGlycine tomentellaRoots

The antioxidant and antityrosinase activities of the water extract ofFlemingia macrophyllaroot (WEFM) were investigated. The results showed that WEFM exhibited radical scavenging and reducing activities, as well as ferrous ion chelating property. In addition, WEFM also protected phospholipids against oxidation, indicating that WEFM could protect biomolecules from oxidative damage. Meanwhile, in the range of 50–100 μg/mL, the tyrosinase inhibitory activity of WEFM increased with an increase in sample concentration and was superior to that of the water extract ofGlycine tomentellaroot (WEGT). A high performance liquid chromatography analysis was used to determine the phenolic components, revealing that daidzin, daidzein, genistin, and genistein were present in WEFM and WEGT. Acting as an antioxidant and a tyrosinase inhibitor, these bioactive constituents could contribute to the protective effects of WEFM. Overall, the results showed that WEFM might serve as a natural antioxidant and tyrosinase inhibitor.
