Datura wrightii · Accepted scientific name

Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆

Datura wrightii, commonly known as sacred datura, is a striking perennial shrub native to the southwestern United States and Mexico. This plant is most notable for its large, trumpet-shaped flowers that bloom under the moonlight. Within these delicate floral structures, the plant synthesizes potent tropane alkaloids, including atropine, hyoscyamine, and scopolamine. These powerful chemicals make the species highly toxic and capable of inducing intense hallucinations if ingested. Because of its potent chemical makeup, careful respect is required when studying this fascinating yet dangerous botanical specimen.

Biological Activities

Compounds

Datura wrightii is a plant species known to harbor several potent tropane alkaloids. Chemical analysis through thin-layer chromatography has confirmed that this species contains atropine. In addition to this, the plant is also a source of hyoscyamine. It has further been identified as containing scopolamine, which contributes to its physiological effects. These combined chemical properties can lead to significant medical outcomes, such as mydriasis, upon accidental exposure.

Conditions

Preparations

Parts used

Datura wrightii possesses unique botanical characteristics, particularly within its highly potent flowers. These specific floral parts contain a concentrated mixture of tropane alkaloids, including scopolamine, hyoscyamine, and atropine. Exposure to these components can lead to significant physiological effects, such as the painless mydriasis observed in a pediatric case study. Because the alkaloids are easily absorbed through contact, handling the flowers can result in accidental pharmacological toxicity. Understanding the chemical composition of these plant parts is essential for recognizing the risks associated with accidental exposure.
