Brunfelsia is a genus of about 40
species. Linnaeus named the genus for early German herbalist Otto Brunfels
Brunfelsia is an erect, smooth shrub growing to a height
of 3 to 4 meters. Leaves are simple, green to yellowish-green, elliptic
to obovate, with entire margins, 5 to 10 centimeters long, pointed at both ends,
crowded on the ultimate twigs. Flowers are fragrant, terminal or axillary, solitary
or in pairs, shortly stalked, with five broad petals. Calyx is green, ovoid, 6
millimeters long and 5-toothed. Corolla tube is about 4.5 centimeters long, slender and
straw-colored; the limb is white to yellow, oblique and unequally 5-lobed,
about 5 centimeters in diameter. The fruit is rounded, about 1.5 centimeters in diameter,
with a yellow and somewhat fleshy pericarp and containing numerous seeds.
- Recently introduced
to the Philippines.
- Cultivated in Manila and other large towns for ornamental purposes.
- Introduced from tropical America.
- Phytochemical investigations have yielded steroids, flavonoids, tannins, and saponins.
- Yields normal fatty acids, and uncommon fatty acids such as ricinolic acid together with cyclopropenoids.
- Flowers emit a sweet scent with inebriating effects reminiscent of Brugmansia suaveolens. The fragrance emerges with the night and disappears with the dawn.
- Considered tonic, antioxidant, anti-diarrheal.
Propagated by stem cuttings.
- No recorded medicinal use in the Philippines.
- In Martinique, fruit is astringent, used
as a tonic; the syrup used for chronic diarrhea.
- In French Guiana, sugary fruit made into an astringent syrup for diarrhea
In a Bangladesh study evaluating the cytotoxicity activity 35 plant species
by the brine shrimp lethality bioassay, the methanolic extract of Brunfelsia
americana showed moderate cytotoxicity with LC50 less than 10.00 ug/ml.
• Antioxidant:Study using a TLC-DPPH screening assay showed a high level of antioxidant activity.
