摘要
研究红海榄的化学成分.将红海榄的细枝粉碎后用95%乙醇浸提、回流热提,合并浓缩,浸膏的乙酸乙酯萃取物,经柱色谱分离,并应用EI MS,1H NMR,13C NMR等谱学方法确定其结构.从福建浮宫九龙江河口采集的红海榄中分离得到9个化合物,分别为β-谷甾醇(1),胡萝卜甙(2),Taraxerol(3),Careaborin(4),Cis-careaborin(5),2,6-二甲氧基-对羟基苯甲醛(6),异香草酸(7),原儿茶酸(8),2,4,6-三甲氧基苯酚(9).其中化合物(6),(7),(8),(9)为首次从该种植物中分离获得.
The chemical constituents of Rhizophora stylosa,which occurs in the intertidal zones of tropical and subtropical coastlines were studied. The twigs of Rhizophora stylosa were collected from Fugong Fujian in July 2002. The air-dried and powdered plant material（8.5 kg） was estracted with 95% ethanol. Removal of the sovlent from the combined 95% ethanol extracts under reduced pressure gave a residue（490 g）. The extract was taken up in H2O and treated with EtOAc. The EtOAc fraction（40 g） was subjected to column chromatography over a column of silica gel（200～300 mesh） using solvent from petroleum ether to acetone. All fractions were collected and the fractions showing similar spots were combined. The residues were subjected to rechromatography over silica gel or sephadex LH-20 to yield 9 pure compounds. Their structures were indentified by EIMS,^1H NMR and ^13C NMR analysis and the spectral data were compared with those reported in literatures. Nine compounds are isolated from Rhizophora stylosa of Fugong, Fujian province by using column chromatography. The nine compounds a re β-stitosterol （ 1 ）, dausterol （2）, taraxerol （ 3）, careaborin（4） ,cis-careaborin（5）, 2,6-dimethoxy-p-hydroxybenzal-dehyde （ 6 ）, 2,4,6-trimethoxy-phenol （7）, protocatechuic acid （8）. Compound（6）, （7）, （8）, （9） are isolated from this genus for the first time.
