摘要
目的研究报春花科报春花属植物胭脂花(Primula maximowicziiRegel)的化学成分。方法运用多种色谱方法,从胭脂花全草中分离得到9个化合物,通过理化性质和波谱数据鉴定化合物的结构。结果分离得到的化合物结构为:山柰酚3-O-β-D-葡萄糖基(1→2)-β-D-葡萄糖基(1→6)-β-D-葡萄糖苷(1),山柰酚3-O-(2″,6″-二-O-α-L-鼠李糖基)-β-D-半乳糖苷(2),槲皮素3-O-(2″,6″-二-O-α-L-鼠李糖基)-β-D-半乳糖苷(3),山柰酚3-O-β-D-半乳糖苷(4),槲皮素3-O-β-D-半乳糖苷(5),杨梅素3-O-β-D-半乳糖苷(6),山柰酚3-O-(2″,6″-二-O-α-L-鼠李糖基)-β-D-葡萄糖苷(7),槲皮素3-O-(2″,6″-二-O-α-L-鼠李糖基)-β-D-葡萄糖苷(8),樱草苷(9)。结论化合物1为新化合物,化合物2~8为首次从该属植物中分离得到,化合物9为首次从胭脂花中分离得到,同时本实验将化合物9的13C-NMR数据补充完整。
OBJECTIVE To study the chemical constituents of Primula maximowiczii Regel.METHODS Nine compounds of the aerial part of P.maximowiczii were obtained by column chromatography.Their structures were elucidated by spectroscopic data and physical-chemical properties.RESULTS Nine compounds were isolated and identified as kaempferol 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside(1),kaempferol 3-O-(2″,6″-di-O-α-L-rhamnopyransoyl)-β-D-galactopyranoside(2),quercetin 3-O-(2″,6″-di-O-α-L-rhamnopyransoyl)-β-D-galactopyranoside(3),kaempferol 3-O-β-D-galactopyranoside(4),quercetin 3-O-β-D-galactopyranoside(5),myricetin 3-O-β-D-galactopyranoside(6),kaempferol 3-O-(2″,6″-di-O-α-L-rhamnopyransoyl)-β-D-glucopyranoside(7),quercetin 3-O-(2″,6″-di-O-α-L-rhamnopyransoyl)-β-D-glucopyranoside(8) and primeverin(9).CONCLUSION Compound 1 is a new one.Compound 2-8 are found for the first time in Primula.Compound 9 is firstly obtained from Primula maximowiczii Regel and its 13C-NMR data was supplemented.
