“…A pesar de que muchas plantas ornamentales permanecen solamente como cultivadas, en Australia, Suiza y algunas regiones de Estados Unidos un alto porcentaje de las especies que son invasoras fueron introducidas deliberadamente como ornamentales (Reichard & Hamilton 1997, Myers & Bazely 2003. En Costa Rica, algunas especies introducidas como ornamentales ya se han naturalizado y pueden causar problemas, como es el caso de Spathodea campanulata (Bignoniaceae), cuyas fl ores producen un néctar tóxico para los visitantes fl orales, que podría causar daños en la apicultura (Trigo & dos Santos 2000).…”

Introduced plants have become an important component of vegetation around the world. Both data bases and lists of introduced species allow us to compare their distribution and effects on natural ecosystems in different regions, giving us a better understanding of their ecology to develop preventive strategies. Here we present a taxonomic analysis of 1048 introduced plant species from Costa Rica, included in 609 genera of 148 families. We consider that the number of introduced plants is underestimated and it may increase as more investigation is developed in this fi eld. The family with the largest number of species is Poaceae (118 spp.) followed by Fabaceae, with a total of 74. Moreover, 116 families have less than 10 species. A high percentage of the introduced species are herbs (55%) and the use of the introduced plants in Costa Rica is mainly ornamental (52%). For multiple purposes is used 8.9 % of the species, as ornamental, medicinal, and edible. Populations status of the introduced plants in Costa Rica is poorly known for most species and for about 31 % of the species analyzed here this information is completely unknown. From the rest of species, 47 % are cultivated and 22 % naturalized. The geographical origin of these species is extremely diverse; however, tropical Asia (19.4 %) and South America (18.6 %) are the most common origins of introduced plant species in Costa Rica. Here we present the fi rst research on introduced plant species in Costa Rica and to our knowledge the fi rst taxonomic analysis of the introduced fl ora in the Neotropics.

“…There is therefore a need to explore non-surgical interventions. Spathodea campanulata, also known as the African tulip tree, fountain tree or the flame of the forest is widely used as an ornamental plant (Trigo and Santos, 1998;Zaheer et al, 2011). The extracts of leaves, stem bark, flower and roots are used in ethno-medicine for the treatment of various diseases (Ofori-kwakye, 2011).…”

Background: The flower bud exudates of Spathodea campanulata is commonly used as a local eye drop in Nigeria and is anecdotally claimed to improve vision. This study evaluated the anti-cataract activity of Spathodea campanulata (SPCM) flower bud exudates against cataractogenesis using rat lenses. This was done with a view to providing empirical scientific support for the use of the exudates from SPCM in the treatment and management of certain eye disorders. Materials and Methods: Fifty (50) rat lenses were used in this study, i.e. five groups of ten (10) lenses per group. Lenses were incubated in artificial aqueous humor (Normal control) with simultaneous incubation in 30 mM galactose (Untreated cataract). Co-incubation with captopril (Captopril treated cataract); 0.1 mg/ml of the exudate (Exudate treated cataract -Low dose) and 0.2 mg/ml of exudate (Exudate treated cataract-High dose) constituted the study groups. After 72 hr of incubation, lenses were observed for cataract and the preventive potential of the exudate against cataractogenesis was evaluated through the determination of the levels of anti-oxidant parameters such as total protein (TP), glutathione (GSH), malondialdehyde (MDA) and activities of superoxide dismutase (SOD) and catalase (CAT) were evaluated in the lens homogenates. Results: Photographic evaluation of the lenses showed the development of cataract in the untreated cataract group while opacification was retarded in higher dose exudate-treated and captopril treated lenses. Significant decrease in the levels of GSH and total protein, reduction in SOD and CAT activities as well as increase in MDA content were observed in cataractous lenses when compared with the normal control. SPCM displayed a doserelated anti-cataract activity. Captopril showed comparable anti-cataract potential to (0.2 mg/ml) SPCM. GSH, SOD and CAT activity in captopril treated cataract lenses increased to 75.55%, 64.08% and 72.45% of the normal control values respectively. In (0.2 mg/ml) exudate treated cataract lenses; GSH, SOD and CAT activity increased to 57.7%, 76.69% and 80.61% respectively. Conclusion:The study concluded that exudate of SPCM elicited its anti-cataract potential through its anti-oxidant activities.
