Pandanusphenol A and B: Two New Phenolic Compounds from the Fruits of Pandanus tectorius Soland

Two new phenolic compounds, P andanusphenol A (1) and B (2) , were obtained from the fruits of Pandanus tectorius . The ir structures including absolute configurations were determined by extensive spectroscopic analysis including 2D NMR experiments ( 1H- 1H COSY, HMBC , and NOESY ) and HRESIMS results as well as CD data . The substituted pattern of two methoxy group s on the phenyl ring of Pandanusphenol A (1) is rarely seen in natural furofuran lignans
