papaver fugax poiret population khalkhal was shown to contain four major alkaloids, roemerine (0.19%), mecamberine (0.39%), liriodenine (0.20%) and salutaridine (0.10%). papaver caucasicum m. b. population elika was shown to contain four major alkaloids, nuciferine (0.50%), amurensinine (0.15%), lysicamine (0.30%) and nornuciferine (0.40%). lysicarnine and nornuciferine were detected for the fi...

The life history of the trematode Pygidiopsis macrostomum Travassos, 1928 is described for the first time. Rediae and cercariae were obtained from naturally infected snails Heleobia australis (d Orbigny), a new first intermediate host. Metacercariae were found encysted in the mesenteries of three naturally infected guppies, Phalloptychus januarius (Hensel), Jenynsia multidentata (Jenyns) (new h...

Papaver fugax Poiret population Khalkhal was shown to contain four major alkaloids, roemerine (0.19%), mecamberine (0.39%), liriodenine (0.20%) and salutaridine (0.10%). Papaver caucasicum M. B. population Elika was shown to contain four major alkaloids, nuciferine (0.50%), amurensinine (0.15%), lysicamine (0.30%) and nornuciferine (0.40%). Lysicarnine and nornuciferine were detected for t...

Sex allocation theory is considered as a touchstone of evolutionary biology, providing some of the best supported examples for Darwinian adaptation. In particular, Hamilton's local mate competition theory has been shown to generate precise predictions for extraordinary sex ratios observed in many separate-sexed organisms. In analogy to local mate competition, Charnov's mating group size model p...

Free-living microturbellarians are a part of lentic and lotic aquatic assemblages play an important but underestimated role in ecosystems. Consequently, they not included studies on the dynamics freshwater invertebrate communities. We report eight new records from Suquía River (Córdoba, Argentina): Catenula lemnae Dugès, 1832, Stenostomum arevaloi Gieysztor, 193...

Background & Aim: Papaver bracteatum Lindl.  (Papaverace) is an important pharmaceutical plant which contains isoqinoline alkaloids. Isoqinoline alkaloids constitute one distinct group of secondary metabolites of the Papaverace family. Codeine and thebaine are important alkaloids of Papaver bracteatum which use widely due to its medicinal properties. Therefore it is...

Previous studies have shown that the extract of Papaver rhoeas reduces morphine dependence, locomotor activity and reward. In present study, the effects of hydro-alcohol extract of Papaver Rhoeas on the tolerance to analgesic effects of morphine in mice have been investigated using tail flick method. Subcutaneous (s.c.) administration of morphine (1, 2, 5 and 10 mg/kg) induced analgesia. Howeve...
