Phytochemical studies on the stem of Dracaena cambodiana led to the discovery of two new biflavonoids, 8-methylsocotrin-3′-methoxy-4′-ol (1) and 8-methylsocotrin-4′-methoxy-3′-ol (2), together with a known biflavonoid, 8-methylsocotrin-4′-ol (3). Their structures were identified by means of HR-ESI-MS and detailed spectral analysis (UV, IR, and 1D and 2D NMR).
