Antioxidant properties, total phenols and pollen analysis of propolis samples from Portugal.
Pollen analysis, total phenols content and antioxidant activity were studied for the first time in Portuguese propolis samples from Bornes and Fundão regions. Total phenols content was determined by colorimetric assay and their amount was of 329 mg/g of GAE in Bornes sample and 151 mg/g of GAE in Fundão propolis. The antioxidant capacity of propolis extracts was assessed through the scavenging ...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولChemical and Biological Properties of Propolis from the Western Countries of the Mediterranean Basin and Portugal
The chemical composition of propolis from the western countries of the Mediterranean basin and Portugal as well as their biological attributes were reviewed. In the vast majority of these countries, extracts of propolis were predominantly constituted by phenols, with the exception of those from Malta and Sicily in which diterpenes in relative high amounts were identified. In one sample from Alg...
