solanum sitiens/scopolamine

Plant species of the Solanaceae family (nightshades) contain pharmacologically active anticholinergic tropane alkaloids, e.g., scopolamine and hyoscyamine. Tropane alkaloids are of special interest, either as active principles or as starting materials for semisynthetic production of other

BACKGROUND Atropine (Atr) and scopolamine (Scp) are toxic secondary plant metabolites of species within the Solanaceae genus that can accidentally or intentionally reach the food store chain by inaccurate harvesting of any plant material, e.g. for herbal tea infusions. Ingestion may cause severe

Tropane alkaloids (TAs) are toxic secondary metabolites produced by plants of, inter alia, the genera Datura (thorn apple) and Atropa (deadly nightshade). The most relevant TAs are (-)-L-hyoscyamine and (-)-L-scopolamine, which act as antagonists of acetylcholine muscarinic receptors and can induce

Plants have evolved many defenses against insect herbivores, including numerous chemicals that can reduce herbivore growth, performance, and fitness. One group of chemicals, the tropane alkaloids, is commonly found in the nightshade family (Solanaceae) and has been thought to reduce performance and

This study examined the modulatory effect of Black nightshade (Solanum nigrum L) and African eggplant (Solanum macrocarpon L) leaves on cognitive function, antioxidant status, and activities of critical enzymes of monoaminergic and cholinergic systems of neurotransmission in scopolamine-administered

Atropa belladonna is a poisonous plant also called deadly nightshade. Its roots, leaves and fruits contain alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion with other berries. Atropa belladonna acute intoxication is a

In the early morning hours of July 9, 2008, six adult family members were admitted to a hospital emergency department in Maryland with hallucinations, confusion, mydriasis, and tachycardia of approximately 3-4 hours duration. Approximately 4-5 hours earlier, all six family members had shared a meal

Although this year marks the 150th anniversary of the discovery of modern surgical anaesthesia, surgery itself has a much longer history. It is well known that extracts from the opium poppy, Papaver somniferum, were used to dull the pain of surgery during ancient times but less well known that

The nightshades (solanaceae) were used as intoxicants since the ancient civilisations and are still in use today. Their alkaloids, atropine and scopolamine, were the major active substances of the ointments of witches, of medieval "anaesthetics", and of modern poisons for murder. In a medium

BACKGROUND Nightshade plants (Solanaceae) have been utilized as hallucinogenic drugs since antiquity in nearly every culture. The Solanaceae alkaloids, atropine and scopolamine, were the active substances in ointment of witches and medieval anesthetics, and in modern poisons. They are still

Plants that produce atropine and scopolamine fall under several genera within the nightshade family. Both atropine and scopolamine are used clinically, but they are also important in a forensics context because they are abused recreationally for their psychoactive properties. The accurate species

The tropane alkaloids, hyoscyamine and scopolamine, are medicinal compounds that are the active components of several therapeutics. Hyoscyamine and scopolamine are synthesized in the roots of specific genera of the Solanaceae in a multistep pathway that is only partially elucidated. To facilitate

BACKGROUND Atropa belladonna (Engl. deadly nightshade, Cro. velebilje, bunika) is a plant containing pharmacologically active, potentially toxic alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion of black/dark blue belladonna

Thin layer chromatographic methods for quantitative determination of nightshade-specific tropane (l-hyoscyamine, scopolamine) and steroidal alkaloids (α-solanine, α-chaconine) in goji berries (L. barbarum L., Solanaceae) were developed. The analysis of tropane derivatives included separation on
