Two new phenolic acids forsythiayanoside C (1) and forsythiayanoside D (2), were isolated from the fruits of Forsythia suspense (Thunb.) Vahl. Their structures were elucidated on the basis of chemical and spectral analysis, including 1D, 2D NMR analyses, HRESIMS and CD spectrometry. The cytotoxic and antioxidant activities testing showed that compound 2 exhibited free radical scavenging activity.
