Two new phloroglucinols, lysidisides X and Y ( and ), and two known compounds, 2-(2-methylbutyryl)phloroglucinol 1--β-d-glucopyranoside () and ()-resveratrol 3-(6″-galloyl)--β-d-glucopyranoside (), have been isolated from the roots of . The structures of and were elucidated primarily by NMR experiments. Their absolute configurations were deduced via circular dichroism (CD) data and electronic circular dichroism (ECD) calculations. Compounds and exhibited significant antioxidative activities with IC values of 12.0 and 11.8 µM, respectively.
