Two new biflavonoids from the stem of

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