The present study optimized the ultrasound assisted extraction (UAE) conditions to maximize the antioxidant activity [Ferric ion Reducing Antioxidant Power (FRAP)], total phenol content (TP) and content of individual polyphenols of extracts from marjoram. Optimal conditions with regard to amplitude of sonication (24.4-61.0 μm) and extraction temperature (15-35 °C) and extraction time (5-15 min)...

Carnosic acid (CA) and carnosol (CS) are two structurally related diterpenes present in rosemary herb (Rosmarinus officinalis). Although several studies have demonstrated that both diterpenes can scavenge free radicals and interfere in cellular processes such as cell proliferation, they may not necessarily exert the same effects at the molecular level. In this work, a shotgun proteomics study b...

A high degree of selectivity is required during the plant extraction process in order to obtain extracts enriched specific compounds or avoid unwanted ones. Rosemary well known for its antioxidant (carnosic acid, carnosol and rosmarinic acid). The also contains pigments (i.e. carotenoids, chlorophylls) which may cause a colour problem use extract cosmetic formulations, example. Supercritical fl...
