Advances in ISO standardization of bee pollen

Standardization, although voluntary in many countries around the world, is extremely important for regulating the marketing of goods and services. The standardization of a product guarantees quality parameters not only in the production processes but also in the finished product, thus giving greater confidence to consumers.

Special bioactivities of phenolics from Acacia dealbata L. with potential for d...

Some diseases still need better therapeutic approaches, including the prevention of development. Natural resources are investigated with this purpose; among them, we decided to use an invasive plant as a main strategy. This will help in two ways: screening new compounds in flowers prevents the plant from causing widespread damage by controlling the dissemination and also obtains crude material for further appli...

Enzyme inhibitory potential of Ligustrum lucidum Aiton berries

Ligustrum lucidum Aiton and its berries have been used in Chinese traditional medicine for around two thousand years. In the present study, L. lucidium berries harvested in two regions of Portugal were studied. Haemolytic activity and inhibition of oxidative haemolysis as well as the enzyme inhibitory activities (α-amylase enzyme and acetylcholinesterase) were assessed. Results suggest that the different biolog...

Pólen apícola: controlo de qualidade e legislação

Poderá o pólen ser considerado um superalimento?
