英文摘要Fourteen phenolic compounds, comprising four sesquilignans (1-4), five flavonoids (5-9), two phenylethanol glycosides (10 and 11) together with three acylphloroglucinols (12-14), were isolated from Eucalyptus tereticornis. Their structures were elucidated through spectroscopic data analyses and electronic circular dichroism (ECD) calculations. Notably, tereticornisin A (1), phloretin 2 '-O-(6-deoxy-beta-d-glucopyranoside) (6), phloretin 2 '-O-(6-deoxy-beta-d-galactopyranoside) (7), and 2-(4-hydroxyphenyl)ethyl-[6-O-(Z)-feruloyl]-beta-d-glucopyranoside (10) were new compounds. In addition, phloretin-2 '-O-beta-d-xylopyranoside (5) was isolated and definitively assigned for the first time, despite its structure having been previously speculated based on HPLC-UV-MS/MS analysis. Eight of the isolates displayed inhibitory activity against the ABTS free radicals with IC50 values that ranged from 8.07 +/- 0.10 to 14.41 +/- 0.30 mu M, comparable to the positive control (IC50 18.12 +/- 0.21 mu M). 12-14 exhibited no antibacterial activity on methicillin-resistant Staphylococcus aureus (MRSA) strains Newman, USA300, and Mu50, and vancomycin-resistant Enterococcus faecium (VREfm) strain HS-0649.
