Summary

Nowadays the use of plant extracts is very common for a multitude of applications in different fields. Their use depends on their bioactivity and, therefore, on their composition, which is closely related to the extraction method. Extraction is in fact the most important phase in the preparation of plant extracts as the use of different extraction techniques determines the bioactive compounds present. Usually, the bioactive compounds of plant material are made up of multi-component mixtures, and their separation and identification are fundamental processes in the analysis of extracts. Finally, the analysis of plant extracts and/or purified bioactive compounds, involving the application of common in vitro biological and phytochemical screening assays, is essential for correlating the composition with the function of the extracts to identify their bioactivity for targeted applications.


Therefore, given the great interest in plant extracts, this special issue will cover different aspects of their analysis to correlate the extraction techniques with the chemical composition of the extracts and their bioactivity to clarify the characteristics of the compounds of plant origin which could be used as active substances in a wide variety of application.

    Abstract The fruits of the Sea buckthorn (Hippophae rhamnoides L.) are a popular plant food and a valuable health product. Cultivating plants produces a lot of leaves with fine branches as an unnecessary residue, which needs valorization. The aim of the study was to estimate (by HPLC-MS/MS) the qualitative and quantitative content of polyphenolic compounds in different parts of H. rhamnoides (HR), and to determine the level of antioxidant activity of leaves and fruits (by DPPH, ABTS methods and ferrozine test). Up to 19 compounds were identified in different parts of HR. The fruits are rich in flavonoids, including… More >
