Separation of phenylpropanoid glycosides from a Chinese herb by HSCCC.
An effective high-speed counter-current chromatography method was established for the preparative isolation and purification of two phenylpropanoid glycosides from the Tibetan medicinal plant Pedicularis longiflora Rudolph. var. tubiformis (Klotz). Tsoong. With a two-phase solvent system composed of chloroform-n-butanol-methanol-water (4:3:4:5, v/v), 40 mg of an extract of Pedicularis longiflor...
متن کاملPreparative isolation of seven diterpenoid alkaloids from Aconitum coreanum by pH-zone-refining counter-current chromatography.
The aim of this paper was to seek an efficient method to preparative separation of alkaloid compounds from Aconitum coreanum (Guanbaifu), a well-known traditional Chinese medicinal plant for heart disease. Seven alkaloid compounds were successfully purified by pH-zone-refining counter-current chromatography with two-phase solvent system of petroleum ether-ethyl acetate-methanol-water (5:5:1:9, ...
متن کاملPreparative Separation of Isoflavones from Korean Soybean by HPLC
In this study, analytical and preparative HPLC systems were utilized to obtain isoflavones from Korean soybean. The mobile phases were the ternary system of water/acetonitrile/acetic acid. The optimum operating conditions were experimentally determined with the analytical column (C18, 0.46x25 cm 5 micron and the preparative column packed with 15 micron. The experimental variables were the gradi...
متن کاملOne-step separation of four flavonoids from Herba Salviae Plbeiae by HSCCC.
High-speed countercurrent chromatography (HSCCC) was successfully applied to the isolation and purification of four flavonoids from Herba Salviae Plbeiae using stepwise and dual-mode elution with a pair of two-phase solvent systems. The systems composed of n-hexane-chloroform-methanol-water (0.5 : 4 : 3 : 2, v/v/v/v) and chloroform-methanol-water (4 : 3 : 2, v/v/v). Analytical HSCCC was used fo...
