摘要:
目的:研究红树植物白骨壤(Avicennia marina)叶子部位次生代谢产物的结构多样性.方法:采用多种色谱方法进行分离纯化,通过波谱方法,并对照文献鉴定化合物结构.结果:分离并鉴定了21个苯丙素和萘醌类化合物,包括3个新化合物,分别是erythro-guaiacylglycerol-β-ferulic acid ether(1),marinnone A(16)和marinnone B(17);18个已知物,分别是threo-guaiacylglycerol-β-ferulic acid ether(2),eleutheroside E2(3),(+)-lirioresinol A(4),dihydroxymethyl-his(3,5-dimethoxy-4-hydroxyphenyl)tetrahydrofuran-9-O-β-glucopyranoside(5),(+)-lyonire-sinol 3α-O-β-D-glucopyranoside(6),(-)-lyoniresinol 3α-O-β-D-glucopyranoside(7),epi-pinoresinol(8),leucoseceptoside A(9),jionoside C(10),salsaside A(11),ilicifolioside A(12),acteoside(13),isoacteoside(14),ethyl ferulate(15),avicennone D(18),avicenone E(19),avicennol C(20),stenocarpoquinone B(21),其中化合物1和2互为差向异构体,16和17互为同分异构体.结论:化合物1,16,17为新化合物,13个已知化合物2~12,14,15为首次从该属植物中获得.
