1. Chemical profile and antioxidant activity of geopropolis from Melipona subnitida collected inside and outside the nest
Melipona subnitida (“jandaíra”) is a species of stingless bee endemic to the Caatinga, a dry forest in the northeastern Brazilian semi-arid. Propolis is a product containing beeswax and plant resin. It contains compounds that can be able to prevent health problems by protecting cells against damage by oxidative agents. M. subnitida produces geopropolis,

2. Comparative analysis of enzymatic activity of tannase in non-conventional yeasts to produce ellagic acid
Abstract Non-conventional yeasts represent an alternative for microorganisms that are capable to produce the enzyme Tannase (EC 3.1.1.20), which has many applications is the food and pharmaceutical industry as it stands out for its ability to produce ellagic acid out of the enzymatic hydrolysis of ellagitannins. Ellagic acid has been studied in the medical a

3. Extract of Ellagitannins starting with Strawberries (Fragaria sp.) and Blackberries (Rubus sp.)
Abstract Characterize the content of phytochemical compounds present in samples of extracts of strawberry (Fragaria sp.) and blackberry (Rubus sp.). The extraction of said compounds was carried out with solutions of polar solvents, such as acetone, ethanol and methanol, using an experimental design with three factors: state of maturity, resting time and temp

6. Effect of the microfiltration process on antioxidant activity and lipid peroxidation protection capacity of blackberry juice
Phytochemicals are highly concentrated in berries, especially polyphenols as anthocyanins and ellagitannins. These compounds have been associated with antioxidant capacity, lipid peroxidation protection, anti-inflammatory activity, anti-carcinogenic activity, obesity prevention and others. Blackberries are commonly grown and consumed as juice in Latin-Americ

7. Bioactive compounds from Brazilian strawberry cultivars (Fragaria x ananassa Duch.): Characterization and bioavailability of ellagic acid derivatives / Compostos bioativos de cultivares brasileiras de morango (Fragaria x ananassa Duch.): caracterização e estudo da biodisponibilidade dos derivados de ácido elágico
Strawberries are a good source of vitamin C, flavonoids and ellagic acid derivatives and are consumed in Brazil in large quantities. The objectives of the present work were: characterization of different cultivars with respect to the content of bioactive compounds, optimization of the method for quantification of total ellagic acid content, purification and
