Eight phenolic compounds (1–8), including two new compounds (1 and 2), were isolated from the twigs of Gardenia jasminoides. Their structures were determined by means of extensive 1D and 2D NMR spectroscopic studies. Compounds 1–4 were tested for their antimethicillin-resistant Staphylococcus aureus (anti-MRSA) activity. The results revealed that compounds 1–4 showed good inhibition with IZD of 12.2 ± 2.2, 13.8 ± 2.4, 15.2 ± 2.8, and 12.9 ± 2.5 mm, respectively.
