摘要：

In a previous paper, we described the isolation of four new sesterterpenes from Cydonia vulgaris Pers. Here we report the isolation of four new flavonol glycosides (1-4) and nine new a-ionol derived glycosides (5-13) together with the known 3-oxo-alpha-ionol 9-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside (14), vomifoliol 9-O-beta-n-glucopyranoside (roseoside) (15), and vomifoliol 9-O-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyranoside,id (16) from the MeOH extract of the aerial parts of C. vulgaris Pers, (Rosaceae). All structures were elucidated by spectroscopic methods, including the concerted application of one-dimensional NMR and two-dimensional NMR techniques (COSY-90 and HET-COR).
