I was walking in The Garden and looking for Datura for Steve [maybe you remember my post with Datura and our discussion about this dangerous plant]. I found Datura, but near it I found something extremally interesting - Belladonna. Beautifull Lady [from Italian] with great need to kill ;-)

BLACK NIGHTSHADE (Atropa belladonna)


INTRODUCTION :
Atropa Belladonna (black or deadly nightshade) is a perennial shrub that grows up to 4,5 feet tall with oval leaves, greenish purple flowers and black globular berries. The plant is native to Europe. Atropa belladonna is well known for it's deliriant and toxic effects. In ancient Greece an extract of the 'Belladonna' plant was frequently used by woman to enlarge the pupils and it is believed to be be of the main ingredients of the hallucinogenic brews of mediaeval Europe.
Atropa belladonna is used for centuries as a treatment for asthma and hay fever because it possesses antispasmodic properties.

CHEMISTRY :
The active constituents in Atropa belladonna are atropine, hyoscyamine and scopolamine. The same alkaloids are also extracted from Henbane (hyoscyamus niger), Thorn apple (Datura stramonium) and Brugmansia species. In the leaves of the Atropa belladonna the alkaloid contents were reported to be 0,4% in the leaves, 0,5% in the roots and 0,8% in the seeds.

Atropine, hyoscyamine and scopolamine interfere with the acetylcholine transference in the synapses. Acetylcholine is a neurotransmitter of the parasympathetic nervous system. These substances don't prevent the liberation of the neurotransmitter but merely block the receptor sites. This blocking action prevents specific acetylcholine binding to appropriate receptors. Atropine, hyoscyamine and scopolamine increase parasympathetic activity. they produce Sleep EEG patterns and abolish the awakening effect (ß-waves), decrease heart rate, stimulate salivary glands, etc. Atropine is an acetylcholine antagonist, it reverses it's effects completely.

Atropine counteracts the effects of cholinesterase-inhibitors. Nerve gasses, like sarin, and some organic insecticides (alkylphosphates: malathion, parathion, etc ) inhibit cholinesterases.

Cholinesterase is an enzyme that inactivates acetylcholine molecules at the synapses. The enzyme inactivates the neurotransmitter by splitting it into choline and acetic acid. Inhibition of these cholinesterases, resulting in accumulation of acetylcholine in the nervous system, is quit toxic, because it will paralyse breathing apparatus. Atropine reverses the esterase inhibitors effects by preventing specific acetylcholine binding to the receptor sites, producing synaptic depression, thus neutralizing the toxic effects of anticholinesterases.

I agree with Joanna, this is an elegant flower, but as you say, so dangerous. Nice and sharp Greg, showing it all so clearly. The flower colour is definitely unusual, not a pretty one, but well shown, thank you.

Hi Greg, nice shot. I've heard of this plant but I am not familiar with it. It's a very interesting colour, it doesn't look inviting. Nice composition and good details, well done.

Is it a nice flower? Looks like a dead flower to me, but then I read your note and yes my eyes are opened! Very good capture of this deadly nightshade Grzegorz. Excellent read, very well done.
