Abstract:

The aim of this study was to rapidly isolate the major effective flavanoids from the extract of safflower (Carthamus tinctorius) using ODSmedium pressure liquidchromatography (MPLC) and semi-preparative HPLC, guided by a developed fingerprint. Twelve compounds were isolated and their structures were elucidated as kaempferol 3-O-β-D-rutinoside (1), kaempferol 3-O-β-D-glucoside (2), rutin (3),quercetin 3-O-β-D-glucoside (4), 6-hydroxykaempferol 3,6,7-tri-O-β-D-glucoside (5), 6-hydroxykaempferol 3-O-β-D-glucoside (6), 6-hydroxykaempferol 6,7-di-O-β-D-glucoside (7), 6-hydroxykaempferol 3-O-β-D-rutinoside (8), 6-hydroxykaempferol 3,6-di-O-β-D-glucosyl 7-O-β-D-glucuronide (9), isosafflomin C (10), safflomin C (11) and hydroxysafflor yellow A (12) by spectroscopic analysis and comparing with the literature. Our results demonstratedthat preparative pressurized liquid chromatography combined with HPLC fingerprint guide is an efficient tool to isolate the target compounds quickly.
