A new cycloartane-type triterpene glycoside that was called cyclomucidoside C was isolated from the aerial part of the plant Astragalus mucidus Bunge. Its chemical structure was elucidated based on ¹H and ¹³C NMR spectral data (COSY, HSQC, HMBC). Studies of extracts of A. mucidus and cyclomucidoside C did not show antibacterial activity against the three strains Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.

粘黄芪新环粘苷C

从植物黄芪 (Astragalus mucidus Bunge)的地上部分分离出一种新的环阿麻烷型三萜糖苷，称为环粘苷 C。根据¹ H 和¹³ C NMR 光谱数据（COSY、HSQC、HMBC）阐明了其化学结构。对A. mucidus和 cyclomucidoside C提取物的研究并未显示出对大肠杆菌、金黄色葡萄球菌和铜绿假单胞菌这三种菌株的抗菌活性。
