摘要
目的研究窄叶鲜卑花地上部分水提物的化学成分。方法采用HP-20大孔吸附树脂、凝胶柱色谱、反相柱色谱和制备液相色谱等方法进行分离纯化;通过理化性质、波谱数据并结合文献报道数据对比确定化合物结构。结果从窄叶鲜卑花地上部分水提物中共分离得到12个化合物,分别鉴定为:藜芦酸(1)、(+)-cycloolivil(2)、3,7-dimethyl-3(E),6-octadien-5-one-1-O-β-D-glucoside(3)、3,7-dimethyl-3(Z)-6-octadien-5-one-1-O-β-D-glucoside(4)、1-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl-3,7-dimethyl-2(E)-6-heptdiene(5)、(7R,8S)-二氢脱氢二松柏醇-9'-O-β-D-吡喃葡萄糖苷(6)、(+)-1-hydroxypinoresinol-1-β-D-glucoside(7)、茵芋苷(8)、kaempferol 3-O-α-L-arabinopyranosyl-(1→6)-β-D-galactopyranoside(9)、异鼠李素-3-O-[β-D-半乳糖(1→6)]-β-D-葡萄糖苷(10)、isorhamnetin 3-O-α-arabinopyranosyl-(1→6)-β-galactopyranoside(11)和quercetin 3-O-[2'''-O-(E)-caffeoyl]-α-L-arabinopyranosyl-(1→6)-β-D-galactopyranoside(12)。结论所有化合物均为首次从鲜卑花属植物中分离得到。
OBJECTIVE To study the chemical constituents of the aqueous extract from the aerial part of Sibiraea angustata. METHODS The constituents were isolated by various chromatographic techniques( HP- 20 macroporous absorption resin, Sephadex LH -20 gel, Reverse-phase silical gel and PHPLC) and their structures were determined on the basis of physicochemical properties and their spectroscopic data, as well as the literatures. RESULTS Twelve compounds were separated and identified as veratric acid ( 1 ), ( + ) -cycloolivil ( 2 ), 3,7-dimethyl-3 ( E ) -6-octadien-5-one-1 -O-β-D-glucoside ( 3 ), 3,7-dimethyl-3 ( Z ) -6-octadien-5-one-1-O-β-D-glucoside(4), 1-O-β-D-glucopyranosyl(1→2) -β-D-glucopyranosyl-3,7-dimethyl-2 (E) -6-heptdiene ( 5 ), (7R, 8S) -dihydrodehyd-rodiconiferyl alcohol-9'-O-β-D-glucopyranoside (6), ( + ) -1-hydroxypinoresinol-1-β-D-glucoside (7), skimmin ( 8 ), kaempferol 3-O-α- L-arabinopyranosyl- ( 1 →6 ) -fl-D-galactopyranoside ( 9 ), isorhamnetin-3-O-β-D-galactopyranosyl ( 1 →6 ) -β-D-glucopyranoside ( 10 ), isorhamnetin 3-O-α-arabinopyranosyl- ( 1→6 ) -β-galactopyranoside ( 11 ), and quercetin 3-O- [ 2'''-O- ( E ) -caffeoyl ] -a-L-arabinopyranosyl-( 1→6)-β-D-galactopyranoside(12). CONCLUSION All compounds are obtained from the genus of Sibiraea for the first time.
