Plant food supplements with anti-inflammatory properties: a systematic review (I).
ABSTRACT Plant food supplements (PFS) receive great acceptance by European consumers. However, quality and efficacy of these products remain a question of concern. The aim of this systematic review is to summarize and critically evaluate the evidence for or against the efficacy of PFS for coping inflammatory conditions by considering epidemiological and human intervention studies. The review, which consists of two parts, considers Olea europea L., Camellia sinensis L., Vitis vinifera L., and Matricaria recutita L., which are herbal material frequently used also as food. The search retrieved 1251 publications. By applying the inclusion/exclusion criteria, the final number of papers was 91. Vitis vinifera L. showed promising results, but other trials should be performed in order to assessing the efficacy. Surprisingly, it was impossible to draw conclusions for the anti-inflammatory effect of Camellia sinensis L. as green tea. No studies were found on the leaves of Olea europea L. whereas more human trials are needed to assess the anti-inflammatory effect of olive oil. Only one study for Matricaria recutita L. was selected. In conclusion, it is advisable to conduct further studies with more homogeneous population and larger number of subjects by avoiding the heterogeneity of the herbal preparations considered.

ABSTRACT: A comparative analysis of methanol extracts from fruit and leaves of Lycium intricatum Boiss., a Solanaceous shrubbery with the potential to become a high-value crop, was performed by means ofliquid chromatography with photodiode array and electrospray ionisation mass spectrometric detection (LC/PDA/ESI-MS). The total phenolic (TPC), anthocyanin (TAC) and flavonoid (TFC) contents as well as the antioxidant capacity measured by four complementary methods were performed for each sample. The results showed the tested extracts to be rich sources of phenolics; in leaves polyphenols and flavonoids dominate, while in fruit anthocyanins dominate. Nineteen phenolic compounds were detected and fifteen were identified or tentatively characterized based on Photodiode-array ultraviolet visible (PDA) UV–Vis spectra , ESI–MS spectrometric data and spiking experiments with authentic standards. Rutin and chlorogenic acid are the major constituents of the leaves and fruit, respectively. Results obtained in this study have revealed that leaves exhibit better performance in all antioxidant assays. From these results it has been shown that extracts of Lycium intricatum have great potential as a source of phenolics for natural health products.Food Chemistry 05/2015; 174:577–584.

ABSTRACT: The newly developed ePlantLIBRA database is a comprehensive and searchable database, with up-to-date coherent and validated scientific information on Plant Food Supplement (PFS) bioactive compounds, with putative health benefits as well as adverse effects, and contaminants and residues. It is the only web-based database available compiling peer reviewed publications and case studies on PFS. A user-friendly, efficient and flexible interface has been developed for searching, extracting, and exporting the data, including links to the original references. Data from over 570 publications have been quality evaluated and entered covering 70 PFS or their botanical ingredients.Food Chemistry 04/2015; DOI:10.1016/j.foodchem.2015.03.126 · 3.26 Impact Factor
