ABSTRACT
The chemical constituents were isolated and purified by column chromatography and semi-preparative reversed-phase high performance liquid chromatography with silica gel, MCI and polyamide in order to study the chemical constituents of dried flowers of Osmanthus fragrans var. aurantiacus. Their structures were identified by the physical and chemical properties and one-dimensional nuclear magnetic resonance (1H-, 13C-NMR, DEPT), two-dimensional nuclear magnetic resonance (1H-1H COSY, non-decoupled HSQC, HSQC, HMBC), UV, IR and high resolution mass spectrometry data. One new compound (1) and five known compounds (2-6) were isolated from 95% ethanol extract of dried broccoli. They were identified as (9S)-9-hydroxymengastigm-5-en-4-one-9-O-primeveroside (1), oleanolic acid (2), forsythiaside (3), 2-(4-hydroxyphenethyl)-ethanol-(6-acetyl)-β-D-glucopyranoside (4), salidroside (5), and acteoside (6). Compounds (2-6) were isolated from this plant for the first time.
