“…Polysaccharides in plants play key biological roles in many life processes. The mechanisms of pharmaceutical effects of bioactive polysaccharides on diseases have been extensively studied and more natural polysaccharides with various curative effects have been tested and even applied in therapies 24 . In the present study, we obtained polysaccharide samples crude polysaccharides and polysaccharides from Tussilago farfara L. and evaluated their antioxidant activities.…”

In this study, water-soluble crude polysaccharides from Tussilago farfara L. and the polysaccharides, deproteinized and decolorized from the crude polysaccharides were obtained. We evaluated the antioxidant activities of crude polysaccharides and deproteinized polysaccharides in vitro by flow injection analysis chemiluminescence (FIA-CL), based on the inhibition effect of their natural antioxidants on the free radical-induced luminol chemiluminescence. Ascorbic acid was used as positive control. At the optimum operational conditions, the antioxidant activity was measured by plotting the inhibition vs. the content of samples to calculate the IC50. The results showed that deproteinized polysaccharides showed higher scavenging activities on the reactive oxygen species such as superoxide anion radical, hydroxyl radical and hydrogen peroxide than that of crude polysaccharides, but less than that of ascorbic acid. This suggests that Tussilago farfara is a good natural antioxidant and has the potential to be used in the manufacturing of foods and medicines.

“…Thus, the roots of Osmunda japonica Thunb are widely used in traditional Chinese medicine for fever relief, detoxification, and deworming (Xu et al, 2019). Currently, only a few studies have investigated polysaccharides of Osmunda japonica Thunb (Cao, Dai, & Wang, 2011;Dai, Ren, Cao, & Wang, 2017;Wang & Fang, 2004). However, there are relevant references investigating polysaccharide-based coatings (Arnon, Granit, Porat, & Poverenov, 2015).…”

Polysaccharides from Osmunda japonica Thunb (Op) exhibit a wide range of biological activities including antibacterial, anti‐inflammatory, antioxidant, and antitumor effects. Carboxymethyl cellulose (CMC) is a type of cellulose derivative that can form dense films. CMC can slow the respiratory transpiration of tomatoes and reduce water evaporation. Coatings of CMC (0.7% concentration) with various levels of Op (0.02%, 0.04%, 0.06%, 0.08%, and 0.1%) were used to preserve tomatoes at room temperature. The treatment, weight loss, hardness, titratable acidity (TA), respiratory intensity, and concentrations of ascorbic acid, polyphenol oxidase, and malondialdehyde (MDA) were evaluated in tomatoes after 0, 5, 10, 15, 20, and 25 days of storage. Compared with untreated tomatoes, the tomatoes with Op‐incorporated CMC coatings had reduced respiratory intensity, weight loss and ascorbic acid loss, increased TA, controlled MDA, and inhibited the decay of tomatoes. Therefore, the use of Op‐incorporated CMC coatings extended the shelf life and maintained the quality of postharvest tomatoes. Practical applications In the past decades, the use of edible coatings has attracted widespread interest in extending the shelf life of particularly perishable foods. Currently, applications of edible coatings have been proven to be promising as a tool to improve the quality and extend the shelf life of various fruits. But there have been no reports on the effect of Op‐incorporated CMC treatment on the postharvest quality of tomatoes during storage. The purpose of this work is to investigate the efficiency of Op‐incorporated CMC treatment to extend shelf life and provide theoretical guidance for the preservation of tomatoes.

“…Mass spectrometry, spectrophotometric or fl uorescent detection can be used for detection of saccharides after their derivatization (Harvey, 2011;Lamari et al, 2003). Further, saccharides can be determined by gas chromatography, ion chromatography, gel permeation chromatography or capillary electrophoresis (Ouchemoukh et al, 2010;Slimestad and Vågen, 2006;Wang and Fang, 2004).…”

Determination of 5-Hydroxymethylfurfural and Saccharides in Mead

This work is focused on determination of 5-hydroxymethylfurfural (HMF), glucose, fructose and sucrose in meads. Reversed-phase high performance liquid chromatography with spectrophotometric detection was used for the separation of HMF. Saccharides were separated using hydrophilic interaction liquid chromatography with refractive index detector. These techniques were employed for determination of the content of HMF and saccharides in 23 samples of meads obtained from different producers. The content of these compounds is strongly dependent on the technological process of mead production and could be used as a marker of mead quality. The content of HMF is lower in samples obtained from beekeepers than in samples purchased in local stores.
