中文摘要:
      为研究肉苁蓉(Cistanche deserticola Y.C.Ma)大极性的化学成分及其对甲氧西林金黄色 葡萄菌耐药菌(MRSA)的抑菌活性,本研究采用硅胶、MCI gel CHP-20、 ODS、 Sephadex LH-20等柱 色谱和制备液相色谱等手段分离纯化肉苁蓉地下部分的70%乙醇浸提物水萃取部位,并根据理化 性质和谱学数据鉴定化合物的结构,测试其抗MRSA活性。从肉苁蓉乙醇提取物水萃取部位分离 和鉴定11个化合物,分别为6-去氧梓醇(1)、巴尔蒂甙(2)、鼬瓣花次甙(3)、Kankanoside B(4)、梓醇 (5)、二氢梓醇(6)、益母草苷(7)、单蜜力特苷(8)、桃叶珊瑚苷(9)、Kankanoside A(10)、Kankanoside L(11),化合物 5、6、8、9为首次从该植物中获得。11个环烯醚萜苷类化合物的抗MRSA活性试验结 果显示化合物 4、11具有潜在的抗MASR活性,其MIC50分别为56.7 μmol/L和77.2 μmol/L,MIC90分 别为106.6 μmol/L和147.6 μmol/L。
英文摘要:
      This study aimed to investigate the highly polar chemical constituents of Cistanche deserticola Y.C.Ma and evaluate their antibacterial activities against methicillin-resistant Staphylococcus aureus (MRSA). Compounds were isolated through column chromatography (silica gel, MCI gel CHP-20, ODS, and Sephadex LH-20) and purified via preparative HPLC. Structural elucidation was achieved using spectroscopic analysis (MS, 1 HNMR, 13C NMR) and comparison with literature data. Eleven compounds were identified as 6-deoxycatalpol (1), bartsioside (2), gluroside (3), kankanoside B (4), catalpol (5), dihydrocatalpol (6), ajugol (7), monomelittoside (8), aucubin (9), kankanoside A (10), and kankanoside L (11). Compounds 5, 6, 8, and 9 were reported for the first time in Cistanche deserticola Y.C.Ma. Anti-MRSA evaluation revealed that compounds 4 and 11 exhibited significant inhibitory effects, with MIC50 values of 56.7 μmol/L and 77.2 μmol/L, and MIC90 values of 106.6 μmol/L and 147.6 μmol/L, respectively.
