Abstract:
Chemical constituents from the air dried parts of
Cichorium glandulosum were studied. The chemical constituents of
C. glandulosum were separated and purified by means of silica gel, Sephadex-LH 20, ODS column chromatography and semi-preparative high performance liquid chromatography. The structure was elucidated by physicochemical characteristics and spectral data. One new flavonoid glycoside was isolated from
C. glandulosum, and identified as quercetin-3-
O-[6″-
O-(3-ethoxy-1, 3-dioxopropyl)]-
β-D-glucopyranoside(
