Insights into the bioactivities and chemical analysis of Ailanthus altissima (M...

In recent years, several analytical methods for characterising the Ailanthus altissima (Mill.) Swingle have aroused interest in the scientific community, since this species is not only considered an invasive alien species, but also possesses a wide and complex number of chemical compounds. These compounds are studied with the aim of ascertaining their biological activities, which could help to understand their ...

Lavandula spp. secção Stoechas : contribuição para a sua identificação na regiã...

Em Portugal, crescem espontaneamente espécies de Lavandula da secção Stoechas Ging. Estas espécies são consideradas Plantas Aromáticas e Medicinais (PAM) devido à produção de metabolitos secundários com propriedades terapêuticas e aromáticas. Devido ao seu elevado polimorfismo e capacidade de hibridação na natureza, torna-se importante o conhecimento e distinção entre as espécies e subespécies. Apesar de alguns...

Potential Applications of the Cytisus Shrub Species: Cytisus multiflorus, Cytis...

Cytisus spp. is present throughout the Portuguese territory. Although most of these species are considered native in Portugal, at least one species has already been reported as invasive in other parts of the world. Different measures of control have been investigated, and the application of herbicides is the most commonly used. This review gathers information about the biochemical profile and analytical methods...

Cistus ladanifer L. tissue culture from leaf and stem explants.

Cistus ladanifer L. exudes a phenolic and terpenoid resin with interesting bioactive and aromatic properties. Despite its high abundance in the wild, this plant can be cultivated to advantage on oligotrophic and trace-elements contaminated soils. Plant tissue culture may be used to produce specific metabolites or for clonal propagation of specific genotypes for plantation. From a biotechnological perspective th...

Cistus ladanifer seeds: from ancient snack to novel and sustainable food ingred...

Cistus ladanifer is a persistent, abundant and widespread underexplored resource in the Iberian Peninsula. The seeds have been used as food for centuries, although their nutritional value and potential as food ingredients have not been exploited until now. In this study seeds from natural shrubland were collected three times during summer for two consecutive years. Analytical evaluation of the macronutrient con...

Characterisation of the phenolic profile of Acacia retinodes and Acacia mearnsi...

Acacia spp. is an invasive species that is widespread throughout the Portuguese territory. Thus, it is pertinent to better understand this species in order to find different applications that will value its use. To evaluate the phenolic profile in Acacia flowers, ethanolic extracts obtained through an energized guided dispersive extraction were analysed, focusing on two species, Acacia retinodes and Acacia mear...

As atividades de ciência cidadã para um controlo de acácias mais sustentável

As espécies exóticas invasoras são uma das principais causas de perda de biodiversidade, afetando seriamente as atividades económicas e sociais em espaço rural. Em Portugal, as plantas lenhosas invasoras com maior impacto nas áreas florestais são Acacia spp. ocupando cerca de 18.000 ha. O aumento crescente deve-se, entre outros fatores, aos incêndios florestais, em que o efeito do fogo estimula a germinação e o...

Caracterização do perfil fenólico em extratos de flores de acácia spp.

Caracterização do perfil fenólico em extratos de flores de acácia spp.

Environmental and morphological traits in three sympatric Lavandula section sto...

Morphological characterization is one of the crucial assessments for differentiating between species and subspecies. In the genus Lavandula, hybridization and polymorphism phenomena occur naturally, which can make it difficult to classify species/subspecies. In this study, 120 specimens of Lavandula species were collected in eight locations in the Beira Interior region. The collection sites were Cebolais-Castel...
