This study addresses the chemical composition of some commercial essential oils (clove, juniper, oregano, and marjoram oils), as well as appropriate herbal extracts obtained in the process of cold maceration and their biological activity against selected Escherichia coli strains: E. coli ATTC 25922, E. coli ATTC 10536, and E. coli 127 isolated from poultry waste. On the basis of the gas chromat...

Campomanesia sessiliflora O. Berg is a medicinal plant that object of very few studies in the literature. In this context, antioxidant activity, sun protection factor (SPF) and toxicity Artemia salina Leachs were analysed, as well contents phenolic compounds, flavonoids tannins aqueous extracts prepared by infusion maceration C. leaves. Maceration showed higher levels compounds regarding two sa...

there is the need for new drugs with better action and lesser side effects. a lot of research is being undertaken to find out new plant drugs, their extraction and pharmacological evaluation. one of such plant is curcuma aromatica whichbelongs to the genus curcuma and reported to have high ethno-botanical values in traditional medicine. the present study evaluates comparative pharmacological ac...

A strategy to increase shelf life of Empeltre olive oils could consist in the incorporation flavoring agents (rich antioxidant compounds). The aim this study was describe quality flavored with rosemary and garlic at different concentrations methods (maceration co-processing during malaxation). malaxation increased total phenol content capacity. Aromatization (added malaxation) more than 50%. Ch...

The aim of the study was to determine relevance microorganisms present during carbonic maceration vinification in specific attributes young red wines produced by this method. For purpose, were made two winemaking methods: and standard method destemming crushing, starting from same batch grapes. microbiological population initial grapes homogenised means a “pied de cuve”, afterwards, microbial e...

Mung bean (Vigna radiata) sprout is commonly consumed as a vegetable, while the coat of the germinated mung bean is a waste. In this paper, an ultrasound-assisted extraction method has been developed to extract natural antioxidants from the seed coat of mung bean. Several experimental parameters-which included ethanol concentration, solvent/material ratio, ultrasound extraction time, temperatur...

Polyphenolic compounds, as a secondary metabolite of plants, possess great nutritional and pharmacological potential. Herein, we applied the green analytical method to study the nutrient profile of Rosa rugosa petals and liqueurs manufactured from them. Using the fast and validated ultra performance liquid chromatography-photodiode detector-quadrupole/time of flight-mass spectrometry (UPLC-PDA-...

The vegetal species Arachis repens, commonly known as peanut grass, was studied and, for the first time, we detected the presence of the bioactive compound trans-resveratrol (t-RSV). We compared the efficiency of three different methodologies (conventional maceration [CM], ultrasound-assisted extractions [UAE], and microwave-assisted extractions [MAE]) concerning total phenolics (TP) and resver...
