Abstract: Modern separation techniques such as D101 macroporous resin, MCI macroporous resin, positive and negative silica gel, gel column chromatography and semi-preparative high performance liquid chromatography were used to separate, purify and identify the chemical components in 95% ethanol extracts of Cinnamomum burmanni leaves from Meizhou, Guangdong Province. At the same time, the antibacterial activities of the compounds were determined by microplate method, and their anti-inflammatory activities were determined by LPS-induced BV2 cells. The results showed that 25 compounds were isolated and identified from the 95% ethanol extracts of C. burmanni leaves, including flavonoids (13), lignans (46), simple phenylpropanoids (716), coumarins (18), benzoquinones (2021), sesquiterpenes (2224) and indole alkaloids (25). Except for compounds 1, 2, 5 and 18, all of them were isolated from C. burmanni for the first time. The results of antibacterial experiments showed that compounds 20 and 21 showed good antibacterial activity against Staphylococcus aureus, with MIC of 32 μmol·L–1, while MBC of compound 20 was 64 μmol·L–1, and MBC of compound 21 was 32 μmol·L–1. The results of antibacterial kinetics also showed that compound 21 had better antibacterial activity than compound 20. The results of anti-inflammatory experiments showed that compounds 5, 6 and 7 could inhibit the production of NO in BV2 cells induced by LPS, and showed good anti-inflammatory activity, the IC50 values were 7.85 μmol·L–1, 24.97 μmol·L–1 and 7.49 μmol·L–1, respectively.

摘要: 采用D101大孔树脂、MCI小孔树脂、正反相硅胶、凝胶柱层析和半制备型高效液相色谱等分离技术对广东梅州产阴香Cinnamomum burmanni叶95%乙醇提取物的化学成分进行分离纯化和结构鉴定,用微孔板法测定化合物抗菌活性,以LPS诱导的BV2细胞测定化合物抗炎活性。结果表明,从阴香叶95%乙醇提取物中分离鉴定了25个化合物,包括黄酮类化合物(13)、木脂素类化合物(46)、简单苯丙素类化合物(716)、香豆素类化合物(18)、苯醌类化合物(2021)、倍半萜类化合物(2224)和吲哚生物碱(25),除化合物12518以外,其余都是首次从阴香中分离得到。化合物2021对金黄色葡萄球菌表现出较好的抑菌活性,MIC均为32 μmol·L–1,化合物20的MBC为64 μmol·L–1,化合物21的MBC为32 μmol·L–1。抑菌动力学实验也表明,化合物21的抗菌活性优于化合物20。化合物567可抑制LPS诱导的BV2细胞NO的生成,表现出较好的抗炎活性,IC50值分别为7.85 μmol·L–1、24.97 μmol·L–1、7.49 μmol·L–1
