TL;DR: This paper presents a review of the ultrasonically assisted extraction of bioactive principles from herbs under European community grants under the COPERNICUS programme and in a COST D10 network.
991 citations
TL;DR: A series of experiments has been developed to investigate the effect of ultrasonic energy on the vegetal material and the solvent used and several results concerning the ultrasonic extractive value, ultrasonic swelling index and the effects of frequency on Vegetal material are presented.
554 citations
TL;DR: In this article, the authors discuss the development of these methods and review the advantages which can be achieved and discuss the advantages of using these methods in the extraction of vegetal material.
Abstract: In order to identify the chemical constituents of vegetal material it is important that an efficient extraction procedure is followed which provides both an efficient extraction and also limits the decomposition of extracted compounds during the process. Traditional methods such as distillation, solvent extraction and cold compression continue to be used but significant improvements can be achieved with the application of either ultrasound or microwave technologies. In this review we will discuss the development of these methods and review the advantages which can be achieved.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: The anticancer effects of phenolics in-vitro and in- vivo animal models are viewed, including recent human intervention studies, and possible mechanisms of action involving antioxidant and pro-oxidant activity as well as interference with cellular functions are discussed.
Abstract: Phenolics are broadly distributed in the plant kingdom and are the most abundant secondary metabolites of plants. Plant polyphenols have drawn increasing attention due to their potent antioxidant properties and their marked effects in the prevention of various oxidative stress associated diseases such as cancer. In the last few years, the identification and development of phenolic compounds or extracts from different plants has become a major area of health- and medical-related research. This review provides an updated and comprehensive overview on phenolic extraction, purification, analysis and quantification as well as their antioxidant properties. Furthermore, the anticancer effects of phenolics in-vitro and in-vivo animal models are viewed, including recent human intervention studies. Finally, possible mechanisms of action involving antioxidant and pro-oxidant activity as well as interference with cellular functions are discussed.

TL;DR: In this article, the main factors affecting the yield of biodiesel, i.e. alcohol quantity, reaction time, reaction temperature and catalyst concentration, are discussed, as well as new new processes for biodiesel production.
2,207 citations
TL;DR: The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation.
2,046 citations
TL;DR: This review presents a complete picture of current knowledge on application of ultrasound in food technology including processing, preservation and extraction and provides the necessary theoretical background and some details about ultrasound the technology, the technique, and safety precautions.
