| 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. |
