Opis:
Fireweed (Epilobium angustifolium L., Onagraceae) is one of important medicinal plants used especially in the treatment of urogenital disorders, including benign prostatic hyperplasia (BPH) and prostatitis. The therapeutic effects of E. angustifolium extracts comprise antiproliferative, anti-inflammatory, immunomodulatory, antioxidant, and also antimicrobial activities. The aim of the present review was to provide the information on the botany, phytochemistry and traditional uses of E. angustifolium. This plant is a widespread circumboreal species of North America and Eurasia, tolerant in terms of habitat conditions, and often occupying man-made open habitats. Phytochemical studies on E. angustifolium resulted in the identification of about 250 different metabolites, including about 170 substances found for the first time in this plant in the last six years (2014–2019). Fireweed has an abundance of polyphenolic compounds, particularly ellagitannins. Oenothein B and quercetin-3-O-glucuronide are proposed as markers for the identification and standardization of the plant raw material. E. angustifolium exhibits significant phytochemical variability in relation to the geographical origin, plant part and time of harvest/vegetation phase. Survey of the ethnobotanical literature showed that the above-mentioned species has been widely used not only as a medicinal, but also as an edible, honey and decorative plant.

Opis:
In the current study, it was hypothesized that the addition of strawberry polyphenol-rich fractions to a high-fructose diet mitigates disorders in liver functions, lipid metabolism, and in the antioxidant and pro-inflammatory status of rats. Therefore, a fraction rich in ellagitannins and proanthocyanidins (EP), and a fraction containing compounds of both mentioned classes of polyphenols and additionally anthocyanins (EPA), in doses of 0.28 and 0.70 g/100 g, respectively, were added to a standard or a high-fructose diet administered to rats for six weeks. The EPA fraction was more beneficial in alleviating the consequences of consuming excess fructose in the diet than the EP fraction. Probably, that fraction containing considerable amounts of carbohydrates was more extensively metabolized by intestinal bacteria, which resulted in higher levels of cecal short chain fatty acids (SCFAs) as well as cecal and urinal ellagitannin metabolites. As a further consequence, diet supplementation with the EPA fraction caused more favorable changes in the levels of serum interleukin 6 and serum antioxidant capacity of water-soluble substances (ACW), in atherogenicity index lg((triglyceride/high-density lipoprotein cholesterol), hepatic oxidized glutathione as well as reduced to oxidized glutathione ratio). Efforts should be made to develop strawberry polyphenol-rich preparations containing the preferred anthocyanins, which is, however, difficult due to the instability of this class of phenolic compounds during the technological process.
