This study was conducted to evaluate the natural variability of total, extractable and non-extractable phenolics in pigmented and non-pigmented rice genotypes (Oryza sativa L.) and to estimate whether the contents and ...

Context: Traditionally, the content of total phenolics (flavonoid phenolics (FP) and nonflavonoid phenolics (NFP)) and flavonoids (flavone/flavonol and flavonone/dihydroflavonol)in propolis has been determined by different ...

In Durango, Mexico, mescal is elaborated from wild plants of Agave durangensis Gentry as a local industry, which with just an industrialization process begins. Contrary to other alcoholic beverages, studies focused to ...

Phenolic compounds (PCs) - with special reference to secondary plant metabolites - were characterised in two Mediterranean olive groves (Olea europaea L.). Representative pedological profiles were dug to identify and ...

The effect of temperature on respiratory activity and total phenol and flavonoid contents in pre-cut celery was assessed within the 24 h following this minimal processing. To this end, celery petioles were cut as strips, ...

The increased rate of sugarcane harvest without previous burn has provided a very favorable environment to the froghopper Mahanarva fimbriolota (Stal, 1854), with high Moisture and low temperature variation. Few works have ...
