Abstract. Two chromanone acid derivatives, calofolic acid B (1) and apetalic acid (2) were isolated from the stem bark of Calophyllum incrassatum. The structures of both compounds were elucidated by UV, IR, HRESIMS, 1D and 2D NMR spectroscopies and comparison of their data with literatures. Compoun...
