Background and Objectives: Supercritical fluid extraction (SFE) technique has been studied for extraction of bioactive compounds from Feijoa sellowiana leaves. Results were compared with those obtained from conventional ethanolic extraction (CE). Materials and Methods: Results: The best supercritical carbon dioxide (SC-CO2) extraction conditions was determined as 250 bar of pressure, 50 &deg...

Botanicals (herbal materials and extracts) are primarily added to the formulations due to different related properties such as antioxidant, anti inflammatory, antiseptic and antimicrobial effects. The bioactive compounds from natural product extracts have been successfully utilized in various applications of the skin care. The bioactive compound from natural product extracts does not possess an...

Background: Agaricus bisporus is an edible basidiomycete fungus. Both the body and the mycelium contain compounds comprising a wide range of antimicrobial molecules, contributing in improvement of immunity and tumor-retardation. Objectives: The presence of endophytes capable of producing bioactive compounds was investigated in Agaricus bisporus. Materials and Methods: Endophytes from Agaricus b...

Elektrokinetické vlastnosti zmesí minerálov Elektroforetický rozptyl svetla (ELS) je nová experimentálna technika umožňujúca merať spectrum elektroforetickej pohyblivosti alebo zeta (ξ) potenciálu skupiny častíc. Toto spectrum odráža distribúciu náboja a čiastočne distribúciu rozmeru týchto častíc. Avšak, okrem modálnej hodnoty napr. zeta potenciálu častíc rovnakého druhu, z ELS spektra môžeme ...
