摘要
在对虫生真菌多菌株生物色素的筛选过程中,发现1株双梭隔梭孢菌株RCEF3669菌丝体明显呈黄色,研究表明,甲醇能够很好地提取出该菌丝体中的黄色色素。利用HPLC法从甲醇提取物中分离1种橙黄色物质Sb-1,HPLC-MS和HPTLC分析证明该物质为一纯化合物,MS分析得出该化合物的分子式为C26H32O9。经Chapman&Hall天然产物数据库查询,该化合物尚未见报道。
ABSTRACT During a screening of pigment of entomogenous fungi, a strain of Septafusidium bifusisporum RCEF3669, mycelia, presented obvious yellow color. An orange yellow pigment Sb-1 from mycelia of RCEF3669 was effectively extracted with methanol and was isolated with HPLC. The pigment was identified with HPLC-MS and HPTLC as a pure compound. High resolution MS analysis revealed that the molecular formula of the compound was C26H32O9, which could possibly be a new compound according the searching results of Chapman＆Hall natural products database.
