Bioactivity of Matricaria chamomilla, Echinacea purpurea, Thymbra capitata and ...
Valente, João Vasco; Gomes, Carolina Proença; Oliveira, Ana Sofia; Rolo, Joana; Gaspar, Carlos; Caramelo, Débora; Gonçalves, José CarlosThe numerous health benefits associated with the use of plants in traditional medicine can be linked to secondary metabolites in the products obtained through the hydrodistillation process, such as hydrolates and essential oils (EOs). This study aimed to assess the chemical profile and the antioxidant, antimicrobial, cytotoxic, and anti-inflammatory activities of two hydrodistillation products obtained from fou...
Natural Mineral Water–Plant Extract Combinations as Potential Anti-Aging Ingred...
Gomes, Carolina P.; Oliveira, Ana S.; Rolo, Joana; Silveira, Tayse F. F. da; Palmeira de Oliveira, Rita; Alves, Maria José; Plasencia, PaulaNatural mineral waters (NMWs) and plant extracts have long been valued for their therapeutic properties and skin benefits. This study investigated, in vitro, the role of five Portuguese NMWs (A-E), combined with plant extracts from five species (Ficus carica L., Rubus idaeus L., Vaccinium myrtillus, Cistus ladanifer and Thymus x citriodorus) as bioactive ingredients. Antioxidant capacity was assessed using the ...
Unlocking Nature’s Anti-Aging Secrets: The Potential of Natural Mineral Waters ...
Gama, Ana Rita; Gomes, Carolina P.; Caetano, Cátia; Oliveira, Ana Sofia; Rolo, Joana; Barros, Lillian; Plasencia, Paula; Garcia, JulianaSkin aging is influenced by intrinsic and extrinsic factors, leading to structural changes in the skin. Current anti-aging cosmetic trends emphasize innovative natural ingredients, including plant extracts, thermal waters, and botanical hydrolats. This work aims to develop six natural anti-aging cosmetics (two serums, two day creams, and two night creams) with innovative and non-irritating profiles. The rationa...
Reproductive toxicity assessment of four portuguese plant hydrolates: Effects o...
Dias, Sandra D.F.; Andrade, L.P.; Rolo, Joana; Gaspar, Carlos; Ruivo, Patrícia Gomes; Oliveira, Ana Sofia; Ferreira, Sandra SaraivaExtracts of aromatic medicinal plants have been extensively studied regarding their numerous bioactivities. However, despite being highly used by humans, studies on the safety of these extracts for animal use are scarce. In this study, we aim to contribute to the determination of the safety profile of plant extracts by focusing on the reproductive toxicity of hydrolates (a by-product of essential oils productio...
Comparative efficacy of essential oils against Cutibacterium acnes: Effect upon...
Oliveira, Ana Sofia; Gaspar, Carlos; Rolo, Joana; Palmeira-de-Oliveira, Rita; Teixeira, João Paulo; Martinez-de-Oliveira, JoséObjectives: Despite being a commensal of human skin, Cutibacterium acnes plays an important role in the pathogenesis of Acne vulgaris, with the loss of bacterial phylotype diversity being related to disease progression. This study evaluated differences in the virulence profile of C. acnes strains from different phylotypes and investigated the possible phylotype-selective efficacy of essential oils (EOs) from Th...
Humulus lupulus aqueous extract and hydrolate as a potential ingredient for cos...
Valente, João Vasco; Oliveira, Rita Palmeira de; Guiomar, Liliana; Vaz, Cátia; Rolo, Joana; Gaspar, Carlos; Oliveira, Ana Sofia; Caramelo, DéboraHumulus lupulus extracts have in their composition different molecules, such aspolyphenols, α-acids, β -acids, and hydrocarbons, which contribute to the plant’s medicinal properties. These molecules are associated with antimicrobial, antioxidant, and anti - inflammatory activities. OBJECTIVE This work focuses on the evaluation of H. lupulus biological activities, with the aim of evaluating its potential for inc...
Study of Ecological Relationship of Yeast Species with Candida albicans in the ...
Caetano, Cátia Filipa; Gaspar, Carlos; Oliveira, Ana Sofia; Oliveira, Rita Palmeira de; Rodrigues, Lisa; Gonçalves, Teresa; Martinez-de-Oliveira, JoséThe role of the fungal community, the mycobiota, in the health of the vagina is currently an important area of research. The emergence of new sequencing technologies and advances in bioinformatics made possible the discovery of novel fungi inhabiting this niche. Candida spp. constitutes the most important group of opportunistic pathogenic fungi, being the most prevalent fungal species in vulvovaginal infections...
Development of a new multiplex PCR to detect prevalent species of house dust mi...
Oliveira, Ana Sofia; Gaspar, Carlos; Rolo, Joana; Pereira, Cristiana Costa; Palmeira-de-Oliveira, Rita; Teixeira, João Paulo; Martinez-de-Oliveira, JoséDermatophagoides pteronyssinus and Dermatophagoides farinae are the most common House Dust Mite (HDM) species in home environments worldwide and responsible for HDM allergy. Since the prevalence of HDM-related clinical conditions is linked to exposure to the mite itself, the detection of HDM in the human households gains importance. We aimed to develop a fast and accessible multiplex PCR to detect and distingui...
Chemical characterization and bioactive potential of Thymus × citriodorus (Pers...
Oliveira, Ana S.; Rolo, Joana; Gaspar, Carlos; Cavaleiro, Carlos; Salgueiro, Lígia; Palmeira-de-Oliveira, Rita; Ferraz, Celso; Coelho, SusanaEthnopharmacological relevance: Thymus × citriodorus (Pers.) Schreb. is an interspecific hybrid between Thymus pulegioides and Thymus vulgaris, known for its pharmacological activities as diaphoretic, deodorant, antiseptic and disinfectant, the last mostly related with its antimicrobial activity. The folk use of other extracts, as hydrolates, have also been disseminated, as regulators of oily skin with anti-acn...
