The stem bark extracts of Calophyllum inophyllum furnished one new furanoxanthone, inophinnin (1), in addition to inophyllin A (2), macluraxanthone (3), pyranojacareubin (4), 4-hydroxyxanthone, friedelin, stigmasterol, and betulinic acid. The structures of these compounds were determined by spectroscopic analysis of 1D and 2D NMR spectral data ((1)H, (13)C, DEPT, COSY, HMQC, and HMBC) while EI-MS gave the molecular mass. The new xanthone, inophinnin (1), exhibited some anti-inflammatory activity in nitric oxide assay.
红厚壳的茎皮提取物除了含有红厚壳素A(2)、桑色素(3)、吡喃雅卡里红素(4)、4-羟基呫吨酮、木栓酮、豆甾醇和桦木酸外,还提供了一种新的呋喃呫吨酮,即红厚壳素(1)。这些化合物的结构通过一维和二维核磁共振光谱数据((1)H、(13)C、DEPT、COSY、HMQC和HMBC)的光谱分析确定,而电子轰击质谱给出了分子量。新的呫吨酮红厚壳素(1)在一氧化氮测定中表现出一定的抗炎活性。
