Two new sucrose derivatives, namely, belamcanosides A (1) and B (2), together with five other known compounds (3-7), were isolated from the seeds of Belamcanda chinensis (L.) DC. Their structures were identified based on spectroscopic data. Especially, the absolute configurations of fructose and glucose residues in 1 and 2 were assigned by acid hydrolysis, followed by derivatization and gas chromatography
从Belamcanda chinensis(L.)DC的种子中分离了两种新的蔗糖衍生物,即belamcanosides A(1)和B(2),以及其他五种已知化合物(3-7)。根据光谱数据鉴定其结构。特别是,通过酸水解,然后进行衍生化和气相色谱(GC)分析,确定1和2中的果糖和葡萄糖残基的绝对构型。在已知化合物中,首次从中华白僵菌中分离出(-)-紫丁香酚(3),(+)-丁香脂醇(4)和槲皮素(5)。另外,在基因水平上针对胆固醇合成和代谢对1和2进行了生物学评估。结果表明,化合物1和2可以调节胆固醇合成和代谢相关基因的表达,
