Secondary Metabolites with Antioxidant and Antimicrobial Activities from .

has important ornamental, medicinal, and food value. It also has tremendous potential for exploiting bioactivities. However, the bioactivities of secondary metabolites in have not been reported. The structures of compounds were determined by spectral analysis and nuclear magnetic resonance (NMR) combined with the available literature on secondary metabolites of leaves. In this study, 15 compounds were identified, including 5 flavonoids (-), a galactosylglycerol derivative (), a terpenoid (), 4 lignans (-), and 4 phenolic acids (-). Compounds - and - were isolated from the genus for the first time. The remaining compounds were also isolated from for the first time. Evaluation of antioxidant and antimicrobial activities revealed that compounds and - exhibited stronger antioxidant activity than the positive drug ascorbic acid, while compounds , , and showed similar activity to ascorbic acid. The minimum inhibitory concentration (MIC) of antibacterial activity for compounds , , , , and against was comparable to that of the positive control drug tetracycline at a concentration of 62.50 µg/mL; other secondary metabolites inhibited and at concentrations ranging from 125-250 µg/mL.
