Trompeta is a small tree or large shrub growing to a height of 3 meters or more. Leaves are simple, opposite, ovate-lanceolate, 13 to 18 centimeters long, 6 to 8 centimeters wide, with pointed tips, unequal, obtuse or rounded bases, with entire or hairy margins. Flowers are large and showy, about 20 centimeters long, creamy white, pendulous, and musk-like in odor. Calyx is tubular, entire and spathelike. Corolla tube is cylindrical with very big lobes.

– Recently introduced in the Philippines.
– Cultivated as an ornamental plant in Baguio.
– Occasional in the lowlands.
– Native of Peru and Chile.
– Leaves and seeds yield alkaloids with narcotic properties.
– Chief alkaloids found in datura are atropine, hyoscyamine, hyoscine (scopolamine) and meteloidine.
– Flowers, leaves, stems and roots contain scopolamine and some hyoscyamine.
– The roots have some atropine and a little hyoscyamine.
– Seeds contain scopolamine and hyoscyamine and a little scopolamine.
– The stem has much hyocyamine and a little scopolamine.
– The leaves contain scopolamine, 0.44% , and an alkaloid, floripondine.
– Flowers have yielded fats, resin acid, tannic acid, glucose, alkaloid, gummy principles, cellulose.
Parts used and preparation
– In Peru, Chile, and other parts of South America, a poultice of leaves is applied externally to accelerate the suppuration of boils and to relieve pain.
– Plant used for belladonna if given in double or treble dosing.
– In Ayurveda, used for arthritis, ulcers, back pain, skin diseases, sciatica, dandruff.
– Used for rheumatism, worms, colds, fever, erisypelas, cramps, asthma, hemorrhoids.
– In the Ecuadorian Amazon, used as hallucinogenic; used by shamans for bewitching and curing. Also, the stems and branches, cut longitudinally are applied to the head or painful body part, bandaged to the area for 15 minutes.
– Plant has been used as hallucinogen and intoxicant from the hyocyamine content.
– The chief alkaloids found in datura are atropine, hyoscyamine, hyoscine (scopolamine) and meteloidine. Poisoning can occur with overdose of any of the alkaloids. As little as 4 grams of leaf can be fatal to a child; alas, as the child’s curiosity is drawn to the plants large flowers and spiny seed capsules.
– Appearance of alkaloid toxicity can be within minutes to hours, depending on concentration, method of ingestion and dosing, manifesting as: extreme thirst, pupil dilatation, vision impairment and hallucinations. High temperature, flushed skin and palpitations may be observed. In non-fatal cases, signs and symptoms subside in 12 to 48 hours, although visual impairment and lethargy may persist for some time.
• Spasmolytic Alkaloids: Results showed dose-dependent reduction of electrical contractions of guinea-pig ileum and reduction of the electrical and the Ach-induced contractions of the ileum. Three active substances identified were tropane alkaloids – atropine, scopolamine and nor-hyoscine.
• Ferredoxin / Amino Acid Sequence: The D. arborea ferredoxin exhibited three or four differences in the amino acid sequence when compared with D stramonium and D metel. The result supports the idea propounded by Bernhardi and Safford that ‘Tree Datura” such as D arborea should be a section of the genus Datura and not a separate genus.
• Antiamoebic: Crude extract of leaves showed moderate antiamoebic activity at MIC of 125 ug/ml. The activity was not due to its alkaloid contents because atropine and scopolamine were inactive in vitro against E histolytica.
• Anti-Dermal Pathogenic Fungi Activity: Study of antibiotic activities of metabolite of entophytic fungi strain isolated from D. arborea isolated four compounds. One compound, a 5-butylpicolinic acid named fusaric acid, could inhibit the growth of Microsporum gypseum and Tricophyton gypseum.
• Aphrodisiac / Antioxidant: Study evaluated a root aqueous extract for aphrodisiac and antioxidant properties. Results showed better results with testosterone levels in blood of test animals. Antioxidant activity was confirmed by comparison with silymarin.
