Primary Metabolite Screening Shows Significant Differences between Embryogenic ...
Caeiro, André; Jarak, Ivana; Correia, Sandra; Canhoto, Jorge; Carvalho, RuiTamarillo is a solanaceous tree that has been extensively studied in terms of in vitro clonal propagation, namely somatic embryogenesis. In this work, a protocol of indirect somatic embryogenesis was applied to obtain embryogenic and non-embryogenic callus from leaf segments. Nuclear magnetic resonance spectroscopy was used to analyze the primary metabolome of these distinct calli to elucidate possible differen...
Seasonal variation of flavonoid content in bee bread: Potential impact on hypop...
Bovi, Thaís de Souza [UNESP]; Caeiro, André; dos Santos, Sérgio Alexandre Alcantara [UNESP]; Zaluski, Rodrigo; Shinohara, Alex Junji [UNESP]Made available in DSpace on 2020-12-12T02:32:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-03-14; Nagase Science Technology Foundation; Bee bread is the main source of proteins necessary for the development of hypopharyngeal glands in nurse bees. However, the seasonal chemical composition and its effects on honey bee physiology are poorly understood. Thus, this study evaluated how the season and bot...
Screening of biological activities of ligustrum lucidum berries: a comparative ...
Delgado, Teresa; Paula, Vanessa B.; Campos, Maria G.; Farinha, Nelson; Caeiro, André; Estevinho, Leticia M.; Anjos, OféliaLigustrum lucidum Aiton including its berries have been used in Chinese Traditional Medicine for around 2000 years. Scientific studies developed on the last decades provided evidence on some biological properties of these products, mostly from particular geographic origins. In the present study, L. lucidium berries harvested in two regions of Portugal were considered. Extracts obtained with 100% ethanol, with 5...
Similarity of Data from Bee Bread with the Same Taxa Collected in India and Rom...
Urcan, Adriana Cristina; Criste, Adriana Dalila; Dezmirean, Daniel Severus; Mărgăoan, Rodica; Caeiro, André; Campos, Maria GraçaBee Bread samples from Romania and India were analysed by microscopy and High Performance Liquid Chromatography with Diode Array Detection (HPLC/DAD) and compared with pollen from the correspondent taxa. The quantification of sugars, fructose/glucose ratio, total phenolics and flavonoids was also carried out. From the results was possible to identify Brassica and Eucalyptus samples that present similar HPLC/DAD...
