The present work explores the antioxidant potential of Helichrysum stoechas (L.) Moench phenoliccompounds for cosmetic applications involving the following steps: chemical characterization, microen-capsulation and incorporation into a moisturizer. Eighteen different phenolic compounds were identifiedin flowering aerial parts (decoction and hydroalcoholic extract), being 3,5-O-dicaffeoylquinic acid andmyricetin ...
Ethnobotanical surveys conducted in Northeastern Portugal have documented the use of Decoctions prepared with flowering aerial parts of Centaurea paniculata L. (starthistles, knapweeds; port. escalabiosa) for inflammation and Helichrysum stoechas (L.) Moench (shrubby everlasting; port. douradinha) for the respiratory system and to reduce fever [1], from the Asteraceae botanical family. Although antioxidant prop...
Natural matrices represent a rich source of biologically active compounds and are an example of molecular diversity, with recognized potential in drug discovery and development. Many plants frequently used in folk medicine have antioxidant and pharmacological properties connected with the presence of phenolic compounds, especially flavonoids [1]. The biological, pharmacological and medicinal properties of this ...
Isabel Cristina F.R. Ferreira Maria Filomena Barreiro Ana Maria Pinto Carvalho ; O presente trabalho teve como objetivo explorar o potencial antioxidante dos compostos fenólicos das sumidades floridas (capítulos e brácteas e os 15 cm terminais dos caules com folhas que suportam as inflorescências) de Helichrysum stoechas (L.) Moench para aplicações cosméticas e envolveu as seguintes etapas: caracterização quím...
As propriedades bioativas de várias plantas têm sido atribuídas à presença de compostos fenólicos, especialmente flavonoides (Mishra et al., 2008). As propriedades biológicas, farmacológicas e medicinais deste grupo de compostos têm também sido exaustivamente estudadas (Marchand, 2002). Estudos etnobotânicos realizados no Nordeste de Portugal registam o uso da decocção de Helichrysum stoechas (L.) Moench (perpé...
