Two significant compounds often found in the gas chromatographic analysis of the acid/neutral extracts from illicit heroin have remained uncharacterized for 30 years. The unknown compounds are referred to as the 'B' and 'C' compounds. It has been postulated that these compounds arise from
The major alkaloids obtained from Papaver cylindricum Cullen were oripavine, narcotine, thebaine and rhoeadine. Floripavidine, papaverine, salutaridine, armepavine, N-methylasimilobine, scoulerine and cheilanthifoline were obtained as minor alkaloids. There have been no previous reports of alkaloids
Species from the section Miltantha are reviewed in the context of their contained alkaloids. Thebaine was isolated as the major alkaloid from a sample of P. fugax together with narcotine, pronuciferine, alpinigenine, O-ethylalpinigenine, amurensinine, N-methyl-crotonosine, armepavine, isocorydine
On the basis of alkaloidal, morphological and chromosomal studies, the section Mecones Bernh. (Syn.: Papaver L., sect. Papaver) has been subdivided into two sections. Thus the new section Glauca J. Novak includes the species Papaver glaucum Boiss. et Hausskn., P. gracile Auch. and P. decaisnei
Papaver plants can produce diverse bioactive alkaloids. Papaver rhoeas Linnaeus (common poppy or corn poppy) is an annual flowering medicinal plant used for treating cough, sleep disorder, and as a sedative, pain reliever, and food. It contains various powerful alkaloids like rhoeadine,
Of the 110 species of genus Papaver, only Papaver somniferum and P. setigerum are controlled poppies in Korea. All poppy samples share similar morphology therefore it is important to check if they contain controlled substances such as morphine and codeine for forensic purpose. Since the alkaloid
The major alkaloids of PAPAVER TRINIIFOLIUM collected in two different parts of Anatolia have proved to be of the aporphine, morphinane and rhoeadine types. The two collections possessed different major alkaloids and the existence of chemical strains is indicated. In addition to the
New alkaloids, (+)-triniifoline, (+)-O-ethyltriniifoline (rhoeadine type), and (+)-miltanthaline (benzylisoquinoline type) have been isolated from aerial parts of Papaver triniifolium Boiss, (Papaveraceae). The major alkaloids were medicinally important (-)-alpha-narcotine and papaverine together
N-methylasimilobine was isolated as the major alkaloid from an Egyptian sample of P. RHOEAS L. Other alkaloids isolated from the same plant material were stylopine, coptisine, isocorydine and rhoeadine. Chromatography indicated the presence of at least nine other minor alkaloids.
BACKGROUND
Papaver rhoeas L. (Papaveraceae) corn poppy, widely distributed in Turkey, is used to make a cough syrup for children, as a tea for disturbed sleep, for pain relief and as a sedative in folk medicine.
OBJECTIVE
Samples of P. rhoeas collected from eight different locations in Turkey and
The alkaloidal contents of the Turkish PAPAVER belonging to the section PILOSA have been studied by high performance liquid chromatography. According to the results obtained, the section PILOSA should be divided into two subsections; the first being characterised by the presence of the alkaloids
