摘要:

HPLC指纹图谱为导向, 应用中压反相硅胶柱色谱以及半制备高压液相色谱两种方法, 对红花提取物中主要化合物进快速分离。共分离得到了12个化学成分, 包括9个黄酮 (1-9)3个查尔酮类 (10-12)。经波谱解析并与文献数据相比对, 鉴定其结构分别为: 山柰酚 3-氧芸香糖苷(1), 山柰酚 3-氧葡萄糖苷 (2), 芦丁 (3), 槲皮素 3-氧葡萄糖苷 (4), 6-羟基山柰酚 3,6,7-三氧葡萄糖苷 (5), 6-羟基山柰酚 3-氧葡萄糖苷(6), 6-羟基山柰酚 6,7-二氧葡萄糖苷(7), 6-羟基山柰酚 3-氧芸香糖苷(8), 6-羟基山柰酚 3,6-二氧葡萄糖苷 7-氧葡萄糖醛酸苷(9), 异红花黄色素C (10), 红花黄色素C (11), 基红花黄色素A (12)。结果表明,加压制备色谱结合指纹图谱导向分离是制备靶标化合物一种快速高效的技术手段

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.
