厚皮香八角果皮的化学成分研究

Chemical Characteristics of Pericarp of Illicium temstroemioides

目的研究厚皮香八角果皮的化学成分。方法利用色谱法对厚皮香八角(Illicium temstroemioides)果皮甲醇提取物中的化学成分进行分离。利用核磁共振、质谱、红外等方法对分离得到的单体化合物进行结构鉴定。结果从厚皮香八角果皮中分离得到了7个化合物,分别是β-谷甾醇(1)2、,6-dihydroxyhumulan-9(E)-3(12),7(13),9-triene(2)、槲皮素-7-甲基醚(3)、原儿茶酸(4)、莽草酸(5)、莽草酸甲酯(6)和胡萝卜苷(7)。结论以上化合物均为首次从该植物中分离得到,化合物2是从该科植物中首次分离得到。厚皮香八角果皮的化学成分特点是含有大量的有机酸和黄酮类化合物。

OBJECTIVE To investigate the chemical constituents in the pericarp of lllicium temstroemioides .METHODS The methanol extract of the pericarp of lllicium temstroemioides was separated with various chromatographic techniques, and their structures were elucidated by physiochemical and spectral analysis. RESULTS β-sitosterol （ 1 ）, 2,6-dihydroxyhumlan-9（ E ）-3 （12）, 7 （13）, 9-triene（2）, quercetin-7- methyl ester（3 ）, protocatecheuic acid（4）, shikimic acid （5）, shikimic acid methyl ester （6） and daueosterol （ 7 ） were isolated from Illicium temstroemioides. CONCLUSION All compounds are found in this plant for the first time. Compound 2 is first found to be present in the family of miciaceae. Organic acids and flavonoids are the main constituents of the pericarp of Illicium temstroemioides.
