Tetrahydroanthracenes as Markers for Subterranean Anthranoid Metabolism in Aloe Species

Publikováno v: Journal of Plant Physiology. 143:596-600

Summary Anthranoids in the roots of 14 Aloe species were surveyed by a novel high-performance liquid chromatographic method and photodiode-array detection and, in leaves of the same species, by thin-layer chromatography. Whereas diastereomeric anthro

Autor: K. P. Odenthal, O. Brehm, Hans W. Rauwald

Publikováno v: Phytotherapy Research. 8:135-140

Fourteen different extracts of nine vasoactive medicinal plants used in European and African phytotherapy and traditional medicine were pharmacologically tested for their possible calcium antagonistic mode of action. The criteria for the selection of

Autor: Karl-Peter Odenthal, Hans W. Rauwald, Oliver Brehm

Publikováno v: Planta Medica. 60:101-105

Based on a screening program of medicinal plants for their possible calcium antagonistic mode of action, the most active lipophilic extract of Ammi visnaga fruits (DAB 10) was fractionated by CC and investigated pharmacologically at K+ (60 mM)-depola

High-performance liquid chromatographic separation and determination of diastereomeric anthrone-C-glucosyls in Cape aloes

Autor: Hans W. Rauwald, Anette Beil

Publikováno v: Journal of Chromatography A. 639:359-362

Isocratic high-performance liquid chromatography using reversed-phase packing (C18) and the solvent system methanol-water (1:1) was successful in separating and determinating the anthrone-C-glucosyls in Cape aloes, allowing a rapid and high resolutio

5-Hydroxyaloin A in the Genus Aloe Thin Layer Chromatographic Screening and High Performance Liquid Chromatographic Determination

Autor: Anette Beil, Hans W. Rauwald

Publikováno v: Zeitschrift für Naturforschung C. 48:1-4

By a comparative thin layer chromatographic screening of the methanol-soluble leaf exudates from more than 400 Aloe plants (183 species), 5-hydroxyaloin A was identified in 20 species. Whilst 13 of the 20 species revealed interindividual variations c
