GC-MS investigation of tropane alkaloids in Datura stramonium.
Alkaloids, GS-MS, Datura stramonium The alkaloid spectrum in roots, leaves and seeds of Datura stramonium L. was investigated by GC-MS. Twenty-nine tropane alkaloids are detected. Twelve of them are new constituents for the species and the two tropane esters 3-(3'-acetoxytropoyloxy)tropane (21) and 3-(2'-hydroxytropoyloxy)tropane (26) are described for the first time.
متن کاملTropane alkaloids of Datura innoxia from Morocco.
Fifty three alkaloids were identified in the organs (roots, stems, leaves, flowers, and seeds) of Datura innoxia by GC/MS. Seventeen of them are reported for the first time for this species and one nor-derivative, 3-phenylacetoxynortropane (28), for the genus Datura. Furthermore, four new tropane esters were tentatively identified as 3-acetoxy-6,7-epoxytropane (acetylscopine) (10), 3-acetoxy-6-...
متن کاملAn analysis of Sorghum halepense’s behavior in presence of tropane alkaloids from Datura stramonium extracts
BACKGROUND This study aimed to quantify the allelopathic potential of Datura stramonium (Jimson weed). Sorghum halepense (Johnsongrass) tolerance was assessed by germinating, seed and growing seedlings, dosing of photo-synthesis pigments, followed by treatment with D. stramonium extract tropane alkaloids. RESULTS Preliminary chemical analysis of the extracts showed the presence of alkaloids.T...
متن کاملCarbohydrate binding studies on the lectin from Datura stramonium seeds.
The carbohydrate-binding properties of the Datura stramonium seed lectin were studied by equilibrium dialysis, quantitative precipitation of natural and synthetic glycoproteins, and hapten inhibition of precipitation. The dimeric lectin (Mr = 86,000) possesses two carbohydrate-binding sites for N,N'N",N"'- tetraacetylchitotetritol /mol protein, with an apparent Ka = 8.7 X 10(3) M-1 at 4 degrees...
متن کاملAntinociceptive effects of oral and intraperitoneal administration of alcoholic Datura stramonium seeds extract in male rats
The present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic Datura stramonium (DS) seed extract as a rich source of alkaloid substances. Male NMRI rats were divided into control and treatment groups. The treatment rats received different doses of the DS seed extract, which was prepared from alcoholic smashed s...
