Phytochemical study of leaves and bark of Crescentia alata HBK


Phytochemical study of the leaves and bark of Crescentia alata HBK. (family Bignoniaceae) using chromatographic techniques yielded three compounds isolated from the bark: a phenylpropanoid, 4-hydroxy-3-methoxybenzoic acid (vanillic acid); a triterpenoid,

How and Why Horses Open Crescentia alata Fruits

Biotropica, 1982
Costa Rican range horses break the hard, ripe fruits of Crescentia alata with their incisors and swallow the small seeds imbedded in the sugar-rich fruit pulp. The seeds survive the trip through the horse and germinate in large numbers where horses have defecated.

Inhibition of nitric oxide synthase expression by a methanolic extract of Crescentia alata and its derived flavonols.

Life Sciences, 2001
In order to validate the use of Crescentia alata (Bignoniaceae) in the traditional medicine of Guatemala as an antiinflammatory remedy, the methanolic (MeOH) extract has been evaluated in vivo for antiinflammatory activity on carrageenin paw edema in rats and in vitro on Escherichia coli lipopolysaccharide- (LPS)-induced nitric oxide (NO) production ...

Seasonal Changes in the Susceptibility of Crescentia Alata Leaves to the Flea Beetle, Oedionychus SP.

Ecology, 1974
Eight experimental Crescentia alata (Bignoneaceae) trees were hand—defoliated during the middle of the rainy season, 1970, in the Guanacaste Province of Costa Rica. The crop of new leaves produced by these trees was severely attacked and eaten by adult Oedionychus sp. (Coleoptera: Alticidae).

The Pattern of Colonization of Epiphytes on Calabash Trees (Crescentia alata HBK.) in Guanacaste Province, Costa Rica

Biotropica, 1982
We examined the structure of the community of epiphytes growing on Crescentia alata trees in Santa Rosa National Park, Costa Rica. Four orchid species were dominant in this community, showing a distinct order of colonization of the calabash trees, with Oncidium cebolleta colonizing first, Encyclia cordigera second, Brassavola nodosa third, and Laelia ...

FRUIT TRAITS, AND SEED CONSUMPTION BY RODENTS, OF CRESCENTIA ALATA (BIGNONIACEAE) IN SANTA ROSA NATIONAL PARK, COSTA RICA

American Journal of Botany, 1982
The pulp in the large hard fruits of Crescentia alata (Bignoniaceae: jicaro) are eaten by horses, surrogate Pleistocene dispersal agents, and the seeds pass through the horse to germinate in dung. I hypothesize that the distribution of jicaro has probably changed dramatically with the introduction of the horse. Two samples of ripe jicaro fruits weighed
