目的研究巴戟天(Morinda officinalisHow.)化学成分。方法运用多种色谱学方法对巴戟天根皮体积分数70%乙醇提取物的化学成分进行分离,并根据光谱数据鉴定化合物的结构。结果从该植物中分离得到17个化合物,分别鉴定为rubiasin A(1)、rubiasin B(2)、2-羟基-1-甲氧基蒽醌(2-hydroxy-1-methoxy-anthraquinone,3)、3-羟基-1-甲氧基-2-甲基蒽醌(3-hydroxy-1-methoxy-2-methyl-anthraquinone,4)、1,3-二羟基-2-甲氧基蒽醌(1,3-dihydroxy-2-methoxy-anthraquinone,5)、2-甲基蒽醌(2-methyl-anthraquinone,6)、1,3-二羟基-2-甲基蒽醌(1,3-dihydroxy-2-methyl-anthraqui-none,7)、2-羟甲基蒽醌(2-hydroxymethyl-anthraquinone,8)、3-羟基-1,2-二甲氧基蒽醌(3-hydroxy-1,2-dimethoxy-anthraquinone,9)、1,8-二羟基-3-甲氧基-6-甲基蒽醌(1,8-dihydroxy-3-methoxy-6-methyl-anthraquinone,10)、苯乙醇-O-β-D-吡喃葡萄糖苷(2-phenylethyl-O-β-D-glucopyranoside,11)、2-丁醇-O-β-D-吡喃葡萄糖苷(sec-butyl-O-β-D-glucopyranoside,12)、3,4-二羟基苯乙醇(3,4-di-hydroxyphenylethanol,13)、3-(4-羟基-苯基)-1,2-丙二醇(3-(4-hydroxyphenyl)-1,2-propandiol,14)、阿魏酸(ferulic acid,15)、熊果酸(ursolic acid,16)、β-谷甾醇(β-sitosterol,17)。结论化合物1,2,11~14为首次从巴戟天属植物中分离得到。
Objective To study the chemical constituents of Morinda officinalis. Methods The chemical constituents of 70% ethanolic extract of Radix Morinda officinalis were separated by various chromatographic methods. The structures of the compounds were identified based on the spectral data. Results Seventeen compounds were isolated from this plant and identified as rubiasin A (1), rubiasin B (2), 2-hydroxy-1-methoxy-anthraquinone , 3-hydroxy-1-methoxy-2-methyl-anthraquinone (4), 1,3-dihydroxy-2-methoxyanthraquinone 1,3-dihydroxy-2-methoxy-anthraquinone, 5), 2-methyl- anthraquinone (6), 1,3-dihydroxy-2-methylanthraquinone -2-methyl-anthraqui-none, 7), 2-hydroxymethyl-anthraquinone (8), 3- hydroxy-1,2-dimethoxy anthraquinone 2-dimethoxy-anthraquinone, 9), 1,8-dihydroxy-3-methoxy-6-methyl-anthraquinone 2-phenylethyl-O-β-D-glucopyranoside (11), sec-butyl-O-β-D-glucopyranoside -D-glucopyranoside, 12), 3,4-di-hydroxyphenylethanol (13), 3- hydroxyphenyl) -1,2-propandiol, 14), ferulic acid (15), ursolic acid (16), Beta-sitosterol (17). Conclusion Compounds 1, 2, 11 ~ 14 were isolated from Morinda officinalis for the first time.
