“…β-Glucan is a natural component of grain that possesses important antioxidant activity (Kofuji et al, 2012).Polysaccharides from plants have been demonstrated to be one of most promising groups of antioxidant compounds (Ng et al, 2004). Polygalacturonase extracted from barley exerts a noteworthy antioxidant effect as well as various biological activities (Kofuji et al, 2012).…”

“…Mushrooms are one of the best sources for the structure of β (1→3) and β (1→6) glucan (Jantaramanant et al, 2014). Polysaccharides from plants have been shown to be a number of the most promising groups of antioxidant compounds (Ng et al, 2004). However, mushroom β-glucan can influence several cellular functions, including cellular glucose uptake (Jantaramanant et al, 2014).…”

Salinity stress causes a considerable reduction in callus growth. Mushroom polysaccharides (β-glucan) are the most promising groups of antioxidant compounds. An in vitro experiment was conducted to evaluate the potential function of exogenously applied β-glucan in alleviating the accumulation of antioxidants in rice callus. In this study, morphological, chemical, and biochemical parameters of an embryogenic callus of the rice variety, MR269, were investigated under 200mM NaCl stress conditions after pre-treatment with (0, 0.5, 1 and 1.5 mg/L) β-glucan in culture media. The present study sought to evaluate chemical, biochemical, and callus growth characterization. The results revealed that callus exposed to stressful media exhibited a significant decrease in callus growth and contents of K + and Ca +2. In addition, significant accumulation of Na + and Na + /K + was found, as well as an enhanced enzymatic antioxidant system and elevated proline activities under NaCl conditions. Furthermore, exogenous addition of β-glucan at 0.5-1.5mg/L under NaCl stress induced a pronounced, significant increase of callus growth, K + and Ca +2 contents, and enzymatic antioxidant and proline activities. In contrast, a significant decrease was found in the levels of Na + and Na + /K + , particularly in callus treated with NaCl. β-Glucan ameliorates the adverse effects of NaCl stress, and the extent of amelioration depends on the type of β-glucan agent as well as treatment duration (three months). The changes mentioned are important for determining the morphological, chemical, and biochemical parameters of salinity tolerance in callus. This study demonstrated that exogenous β-glucan exhibits alleviation of the harmful effects of salt stress and increases salinity resistance in callus rice.

Biological activity and composition of teas and tinctures prepared from Rosa rugosa Thunb. IntroductionRugosa rose (Rosa rugosa Thunb.) is an Asian indigenous plant with a long record of traditional medicinal use. Since its introduction to Europe, the hips and flowers of rugosa rose and its hybrids have been widely available and used for production of teas, wines, juices and jams [1,2]. Rose hips are rich in many vitamins, which have prompted their use in medicine, particularly for conditions accompanied by immune deficiency, e.g. common cold [3]. Despite the great commercial potential of the R. rugosa, only a few reports have been published about the phytochemical content and biological activity of this plant; in particular, the knowledge of its roots and leaves remains limited, which is surprising considering that rose roots have been utilized by Asian folk medicine to treat conditions such as diabetes mellitus, pain and chronic inflammatory diseases [4].Previous research has revealed the presence of many biologically active compounds in all parts of R. rugosa [1,[4][5][6][7]. Many of them act as potential natural antioxidants [8][9][10]. Although some R. rugosa extracts were reported to possess antioxidant properties [5,11], there are no detailed studies on their antiradical potential. Similarly, there are only a few data on antibacterial and antitumor properties of the plant. Petals have been shown to have selective antibacterial activity against intestinal and pathogenic bacteria [12]. In terms of antitumor activity, Lee et al. [13] demonstrated that methanolic extracts from rose stem acted as anti-prostate cancer agents. The antiproliferative activity of juice from R. rugosa fruit on several cancer cell lines was indicated as well [14]. However, there are no precise data about phenolic content in different parts of this plant. Research on the composition and activity of other rose species may suggest that in this respect rugosa rose is also of great importance and potential [3].

“…Gallic acid (3,4,5-trihydroxybenzoic acid, GA), a naturally occurring plant phenol, is abundant in natural plants (15)(16)(17)(18)(19) and it has been reported to have anti-bacterial (20), anti-viral (21), anti-inflammatory (16), antioxidant (22) and antitumor functions in many human cancer cell lines (21)(22)(23). Although GA has been shown to inhibit the growth of prostate cancer cells, there is no available information addressing GA-inhibited migration and invasion of prostate cancer cells in vitro.…”
