Question

Atropine, an alkaloid, is obtained from:
A. Datura stramonium
B. Atropa belladonna
C. Hyoscyamus niger
D. Withania somnifera

Answer 1

Hint: Atropine naturally occurs as a racemic mixture of D- and L-hyoscyamine in plants like henbane (Hyoscyamus niger), belladonna, the mandrake Mandragora officinarum, jimsonweed (Datura stramonium), and Scopolia, all of the family Solanaceae.

Complete step-by-step answer:

Atropa belladonna is a plant that belongs to the family of Solanaceae. Atropine is a naturally occurring tertiary amine (alkaloid) obtained from Atropa belladonna (deadly nightshade). It includes two isomers, d and l hyoscyamine. Atropine is used to reduce mucus, saliva, or other secretions in the airway during surgery. Atropine is sometimes used as an antidote to treat some types of poisoning. The plant is used to produce an alkaloid referred to as atropine. This is an alkaloid that has healing properties. They are also used to treat poisoning due to pesticides. The alkaloid reduces the production of saliva formation during surgery.
Datura stramonium, known by the common name’s jimsonweed (jimson weed), thorn apple, devil's trumpet, or devil's snare, is a species of flowering plant in the nightshade family Solanaceae.
Hyoscine is an alkaloid that is similar to atropine, found in a similar group of plants but normally acquired from the shrub henbane (Hyoscyamus niger).
Ashwagandha comes from the root of the Withania somnifera plant that is used in Ayurvedic medicine to treat lack of energy, stress, and anxiety.

Therefore the correct answer is Option B.

Note: Atropa belladonna, an essential medicinal plant is of the family Solanaceae. Atropa belladonna, widely known as the belladonna or deadly nightshade, is a herbaceous perennial plant in the family Solanaceae. The leaves and fruits are extremely toxic and contain tropane alkaloids. These toxins contain hyoscyamine and scopolamine, which cause hallucinations and bizarre delirium.
