Droplet counter-current chromatography of indole alkaloids from Tabernaemontana hilariana
(Wiley-Blackwell, 1999-03-01)
This paper reports the separation of the indole alkaloids from the benzene extract of the root barks of Tabernaemontana hilariana (Apocynaceae). The crude alkaloid fraction was fractionated by droplet counter-current ...
Preparative separation of the naphthopyranone glycosides by high-speed counter-current chromatography
(Elsevier B.V., 2001-04-27)
High-speed counter-current chromatography was applied to the preparative separation and purification of naphthopyranone glycosides from a crude 70% ethanolic extract of the capitula of Paepalanthus microphyllus. The solvent ...
Preparative isolation of a novel flavonoid from an infusion of Byrsonima basiloba leaves by high-speed counter-current chromatography
(Natural Products Inc, 2007-01-01)
A method for the isolation of three compounds from the infusion of leaves of Byrsonima basiloba A. Juss. by high-speed counter-current chromatography (HSCCC) was developed. This technique led to the separation of a novel ...
