Abstract
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 .
