new phenylpropanoid glucoside from the aerial parts of Lygodium japonicum

A new compound, 4-O-caffeoyl-d-glucopyranose (1), and a new natural product, 3-O-caffeoyl-d-glucopyranose (2), together with six known compounds (3–8) were isolated from the aerial parts of Lygodium japonicum. Their structures were elucidated on the basis of extensive spectroscopic data analyses. Th...

Description
Summary:A new compound, 4-O-caffeoyl-d-glucopyranose (1), and a new natural product, 3-O-caffeoyl-d-glucopyranose (2), together with six known compounds (3–8) were isolated from the aerial parts of Lygodium japonicum. Their structures were elucidated on the basis of extensive spectroscopic data analyses. The oxygen radical absorbance capacity assay was applied to evaluate their antioxidative capacities in vitro, which revealed that 1–8 showed strong antioxidative properties.
