高速逆流色谱法分离纯化丹参并尝试制订中药指纹图谱

open access: yes, 2003
用国产高速逆流色谱 (HSCCC)分离纯化中草药———丹参 ,选用正己烷 乙醇 水体系 ,固定相保留率达到78 8%。采用分步洗脱 ,3个产地丹参各分离得到 12个洗脱组分 ,经高效液相色谱仪和紫外光谱仪检测证明 3张HSCCC洗脱图谱中对应洗脱峰为同一组分。HSCCC洗脱图谱不包含非共有峰 ,并且对应洗脱峰保留时间的相对标准偏差RSD <3% ,符合国家标准关于制订指纹图谱方法学考察资料的技术参数。因此 ...

An efficient method for the preparative isolation and purification of alkaloids from Gelsemium by using high speed counter-current chromatography and preparative HPLC

open access: yes
We established an efficient method using high-speed countercurrent chromatography (HSCCC) combined with preparative high-performance liquid chromatography (prep-HPLC) for isolating and purifying Gelsemium elegans (G. elegans) alkaloids.
