Unveiling the chemistry and bioactivity of bee products and their derivatives
Anjos, Ofélia; Miguel, Maria da GraçaApiculture, or beekeeping, refers to the cultivation and management of honey bees for honey and byproducts, including the extraction, bottling, and sale of hive products such as honey, propolis, royal jelly, bee venom, bee pollen, bee bread and other fermented bee products [1]. Honey is a supersaturated solution or semi-solid natural sweet product produced by both honey bees (Apis subfamily) and stingless bees ...
Anti-inflammatory activity of thymol and thymol-rich essential oils: mechanisms...
Gago, Custódia; Serralheiro, Ana; Miguel, Maria da GraçaThymol, a monoterpenoid phenol present in the essential oils of several aromatic plants, has attracted considerable attention for its anti-inflammatory effects, often in combination with other bioactive compounds. This work explores the mechanisms behind the anti-inflammatory activity of thymol and thymol-rich essential oils, summarizing recent experimental findings. Inflammation, a key factor in numerous chron...
Antimicrobial and wound healing effects associated to cytocompatibility and the...
Machado, Alexandra M.; Marto, Joana; Gonçalves, Lídia Maria; Ribeiro, Helena Margarida; Duarte, Aida; Tomás, Andreia; Falcão, Soraia I.Owing to its applications in both food and pharmaceutical industries honey is regarded as a functional product. This study evaluated 32 Portuguese monofloral honeys and their activity was compared with manuka honey 850 +. The antimicrobial activity was determined against Gram-positive and negative bacteria, and yeast. Antioxidant activity, wound healing ability, and cell viability were studied in the human kera...
Cistus ladanifer L.: essential oils, volatiles, by-products, and their biologic...
Gago, Custódia; Bakchiche, Boulanouar; Djekhioua, Tahar; Miguel, Maria da GraçaCistus ladanifer L., commonly known as gum rockrose, is a Mediterranean shrub of growing interest due to its valuable essential oils (EOs) and labdanum resin. This review synthesizes current knowledge on the chemical composition and biological activities of EOs and hydrolates from C. ladanifer across Mediterranean regions, with particular emphasis on Spain, Portugal, Morocco, and France. α-Pinene, viridiflorol,...
Electrical impedance spectroscopy for potassium content analysis and botanical ...
Elamine, Youssef; Inácio, Pedro M.C.; Miguel, Maria da Graça; Carlier, Jorge D.; Costa, Maria Clara; Estevinho, Leticia M.; Gomes, Henrique L.Minerals are reported to dominate the electrical properties of honey and indicate its botanical and geographical origins. In this study, Electrochemical Impedance Spectroscopy (EIS) was used to assess the relation between mineral elements, electrical properties and botanical origin using three honey varieties - Citrus sp., Eucalyptus sp., and Erica sp. These varieties are identified through pollen analysis and ...
Effectiveness of Sodium Alginate and Carnauba Wax Nanoemulsions with Lemongrass...
Gago, Custódia; Gerreiro, Adriana; Souza, Mariana; Martins, Nuno; Fonseca, Daniela; Cabrita, Maria João; Miguel, Maria da Graça; Antunes, Maria DulceAvocado (Persea Americana Mill.) has gained popularity as a widely produced and consumed fruit worldwide, raising concerns about its storage and transportation. The avocado, being a climacteric fruit sensitive to chilling injury, faces challenges that affect its shelf life and commercial viability. This research delves into the effectiveness of edible sodium alginate 2 % (weight/weight, w/w) (SA) and carnauba w...

Quality assessment of Portuguese monofloral honeys. Physicochemical parameters ...
Machado, Alexandra M.; Tomás, Andreia; Russo-Almeida, Paulo; Duarte, Aida; Antunes, Marília; Vilas-Boas, Miguel; Miguel, Maria da GraçaThe quality evaluation and physicochemical parameters assessment of Portuguese monofloral honeys were performed. Fifty-one monofloral honeys were collected from several regions from mainland Portugal, and from the Azores islands, producer labelled as carob tree (n = 5), chestnut (n = 2), eucalyptus (n = 5), bell heather (n = 6), incense (n = 4), lavender (n = 8), orange (n = 9), rape (n = 2), raspberry (n = 2),...
