摘要
从木瓜叶中分离得到(6 R)-3-氧-4-羟基-7,8-二氢-离子醇1和3-氧-5,6-环氧-离子醇2的9- O -d -葡萄糖吡喃苷。通过XAD-2吸附和甲醇洗脱得到糖苷提取物。经DCCC分离、闪蒸色谱后，进行高效液相色谱纯化。木瓜叶的新成分为过乙酸酯1a和过乙酸酯2a。
Isolation of Two New Ionone Glucosides from Quince ( Cydonia Oblonga Mill.) Leaves
The 9- O - - d -glucopyranosides of (6 R )-3-oxo-4-hydroxy-7,8-dihydro- -ionol 1 and 3-oxo-5,6-epoxy- -ionol 2 were isolated from quince leaves. The glycosidic extract was obtained by XAD-2 adsorption and MeOH elution. After DCCC separation and flash chromatography, purification by high performance liquid chromatography was carried out. The novel quince leaf constituents were characterized as peracetates 1a and 2a .
