چکیده

Two new phloroglucinols, lysidisides X and Y (1 and 2), and two known compounds, 2-(2-methylbutyryl)phloroglucinol 1-O-β-d-glucopyranoside (3) and (E)-resveratrol 3-(6″-galloyl)-O-β-d-glucopyranoside (4), have been isolated from the roots of Lysidice rhodostegia. The structures of 1 and 2 were elucidated primarily by NMR experiments. Their absolute configurations were deduced via circular dichroism (CD) data and electronic circular dichroism (ECD) calculations. Compounds 1 and 2 exhibited significant antioxidative activities with IC50 values of 12.0 and 11.8 µM, respectively.

Selection of Landscape Tree Species of Tolerant to Sulfur Dioxide Pollution in Subtropical China

Sulfur dioxide (SO2) is a major air pollutant, especially in developing countries. Many trees are seriously impaired by SO2, while other species can mitigate air pollution by absorbing this gas. Planting appropriate tree species near industrial complexes is critical for aesthetic value and pollution mitigation. In this study, six landscape tree species typical of a subtropical area were investi...
