摘要

目的: 研究伏康树树皮化学成分。方法: 采用反相硅胶、正相硅胶、Sephadex LH-20 等柱色谱方法进行分离纯化，根据理化常数及波谱数据对化合物的结构进行鉴定。结果: 从伏康树中分离并鉴定了14个化合物，分别为3-OAc，Δ7，bauerenyl acetate（1），β-谷甾醇（2），伏康京碱（3），8-hydroxy-6-methoxy-3-pentylisocoumarin（4），voacristine（5），voacamine（6），22E，24R-5α，8α-epidioxyergosta-6，22-dien-3β-acetate（7），voacristinehydroxyindolenine（8），voacryptine（9），熊果酸（oleanolic acid）（10），β-香树脂醇（β-amyrin）（11），（22E）-3β-羟基-5α，8α-桥二氧麦角甾-6，22-二烯（12），豆甾-4-烯-6β-羟基-3-酮（13），棕榈酸（14）。结论: 除化合物 3，5，6，9 外，其余10个化合物均为首次从该植物中分离得到; 1，4，7，12，13为首次从该属植物中分离得到;化合物4为从该植物中首次分离得到的第1个香豆素类化合物。
