摘要
综合使用硅胶柱色谱、HP20大孔树脂柱色谱、ODS反相柱色谱及Sephadex LH-20凝胶柱色谱等色谱技术对木荷(Schimasuperba)茎皮进行分离纯化,并根据化合物理化性质以及应用MS、NMR技术对分离得到的化合物进行结构鉴定。从木荷中分离得到9个化合物,分别鉴定为三十烷酸(1)、棕榈酸(2)、Dodecanoic acid(3)、松脂素(4)、槲皮素(5)、山柰酚(6)、AmericaninA(7)、槲皮素-3-O-β-D-葡萄糖苷(8)及槲皮素-3-O-α-L-鼠李糖苷(9)。化合物1~4为首次从木荷中分离得到,化合物5、7、9为首次从木荷属植物中分离得到。
Compounds from the stem bark of Schima superba were isolated and purified by a combination of various chromatographic techniques including positive phase silica gel,ODS,Sephadex LH-20 gel,and preparative HPLC methods.Their structures were elucidated by physiochemical property,MS and NMR analysis.Results showed that 9 compounds were obtained from 70%ethanol extract of the stem bark of S.superba and identified as triacontanoic acid(1),hexadecanoic acid(2),dodecanoic acid(3),pinonesinol(4),quercetin(5),kaempferol(6),americanin A(7),quercetin 3-O-β-D-glucopyranoside(8)and quercetin 3-O-α-L-rhamnopyranoside(9).Compounds 1—4 were firstly isolated from S.superba.Compounds 5,7 and 9 were firstly isolated from the genus Schima.
