Studies On The Chemical Constituents Of Flower Of Datura Innoxia Mill

Datura innoxia is dry flower of Datura innoxia Mill. It belongs to the family of Solanaceae. And it can be the substitute of Datura metel L.which is recorded in the .To illustrate the difference of their Chemical constituents the article studied ones of Dutura innoxia Mill..By ion exchange resin 732(001x7) and AB-8 Macropore Adsorb ing resin the water-solubility component except alkaloid was refined and enriched.The further separation was made by using silicagel column chromatography, ODS column chromatography and polyamide chromatography.As a result,eight compounds (1-8) had been isolated from the 50% effective fraction of treatment psoriasis, using 1H-NMR,13C-NMR,compounds:7-O-a-L-rhamnopyranosyl-Ka empferol,7-O-β-D-glucopyranosyl-Kaempferol,3-O-β-D-glucopyran osyl,7-O-a-L-rh-amnopyranosyl-Kaempferol,3-O-β-D-glucopyranos yl-(1-2)-β-D-glu-copyranosyl-Kaempferol,3-O-β-D-glucopyranos-yl-(1-2)-β-D-glucopyranosyl,7-O-a-L-rhamnopyranosyl-Kaempfer ol and 3-O-β-D-glucop yranosyl (1-2)-p-D-glucopyranosyl,7-O-B -D-glucopyranosyl-Kaempferol.The compounds (1-6) were isolated from Datura innoxia Mill, for the first time.At thesame time,the sort of flavonoid in Datura innoxia Mill.and Datura metel L.is essentiall y the same.The result from this article can offer valuable scientific basis f or illuminating the similarities and differences between the chemica 1 constituants of Datura innoxia and Datura metel L., comparing thei r efficiency , and empoldering the resources of Datura innoxia.
