目的研究长柱十大功劳Mahonia duclouxiana Gagnep.的化学成分。方法对长柱十大功劳乙醇提取物进行反复柱层析,通过理化性质和TLC、IR、1HNMR、13CNMR、MS等分析鉴定化合物的结构。结果从长柱十大功劳中分离得到6个非生物碱类单体化合物,分别鉴定为2,3-二羟基-1-(4-羟基-3,5-二甲氧基)-1-苯丙酮(Ⅰ)、丁香酯素(Ⅱ)、丁香脂素-4-O-β-D-葡萄糖苷(Ⅲ)、胡萝卜苷(Ⅳ)、富马酸(Ⅴ)、硬脂酸(Ⅵ)。结论 6个化合物均为首次从该植物中分离得到,化合物Ⅰ为首次从该属植物得到。
Objective To study the chemical composition of Mahonia duclouxiana Gagnep. Methods The ethanol extract of ten major megasporas was subjected to repeated column chromatography. The structures of the compounds were identified by their physicochemical properties and TLC, IR, 1HNMR, 13CNMR and MS analyzes. Results Six non-alkaloid monomeric compounds were isolated from the top ten columns of the long column and identified as 2,3-dihydroxy-1- (4-hydroxy-3,5-dimethoxy) Acetone (Ⅰ), mellow ester (Ⅱ), syringin-4-O-β-D-glucoside (Ⅲ), daucosterol (Ⅳ), fumaric acid (V) and stearic acid (Ⅵ) CONCLUSION Six compounds were isolated from this plant for the first time. Compound Ⅰ was obtained from this genus for the first time.
