摘要
该实验基于前期黑水缬草抗老年痴呆(AD)的作用,对其有效部位进行化学成分研究,采用75%乙醇加热回流的方法对黑水缬草药材进行提取,提取物经萃取和大孔吸附树脂柱色谱分离得到其抗AD的有效部位,采用硅胶、ODS柱色谱以及制备型HPLC等色谱法分离该有效部位并得到9个化合物(1-9),结合质谱及核磁等波谱技术,分别鉴定为6-hydroxy-7-(hydroxymethyl)-4-methy-lenehexahydrocyclopenta[c]pyran-1(3H)-one(1),suspensolide F(2),马钱子苷(3),α-莫诺苷(4),β-莫诺苷(5),patrinovalerosidate(6),野花椒苷A(7),(-)-angelicoidenol-2-O-β-D-glucopyranoside(8)和citroside A(9),其中化合物6-9为首次从缬草属植物中分离得到,进一步对化合物1-9进行体外抗AD活性研究发现化合物2和6对PC12神经元细胞损伤具有显著的保护作用。
In this study,the chemical constituents from Valeriana amurensis AD-effective fraction were investigated based on the effect of Valeriana amurensis on Alzheimer's disease( AD) in previous study. Valeriana amurensis was extracted with 75% ethanol and the obtained extract were extracted and subjected to AB-8 macroporous resin column to obtain the AD-effective fraction of Valeriana amurensis. 9 compounds( 1-9) were isolated with silica gel,ODS column chromatography and preparative HPLC. The structures of these compounds were determined as 6-hydroxy-7-( hydroxymethyl)-4-methylenehexahydrocyclopenta[c]-pyran-1( 3H)-one( 1),suspensolide F( 2),loganin( 3),α-morroniside( 4),β-morronisid( 5),partinovalerosidate( 6),zansiumloside A( 7),(-)-angelicoidenol-2-O-β-D-glucopyranoside( 8),citroside A( 9). Compounds 6-9 were isolated from the valerian genus for the first time and further investigated the anti-AD effect of compounds 1-9 in vitro found that compound 2 and 6 protected the PC12 cells from injury significantly.
