“…Our results obtained in the treatment with β-glucan extracted from Shiitake (the fungi Lentinula edodes ), where the activity of β-1,3-glucanase in the tomato plant was observed throughout the evaluated period, corroborate with the works of [ 23 , 55 , 56 ]. In this way, it is possible to confirm the potential technological application of this polysaccharide extracted from the fruiting bodies of Lentinula edodes for the control of FOL in tomato.…”

The effects of the abiotic inducers β-glucan, extracted from Shiitake (Lentinula edodes), BFIICaB® (Kappaphycus alvarezii) and BKPSGII® (K. alvarezii X Sargassum sp.) on tomato plants infected with Fusarium oxysporum f. sp. lycopersici (FOL) were evaluated through the activity of enzymes related to the induction of resistance at 5 and 10 days after inoculation (DAI). Tomato plants (21 days old, after germination) were inoculated with the pathogen conidia suspension and sprayed with 0.3% aqueous solutions of the inducers. The activities of the enzymes β-1,3-glucanase, peroxidase and phenylalanine ammonia lyase (PAL) were evaluated in fresh tomato leaves collected at 5 and 10 DAI. In all treatments, peroxidase showed the highest enzymatic activity, followed by β-1,3-glucanase and PAL. Between the seaweeds, the inducers extracted from the red alga Kappaphycus alvarezii (BFIICaB®) promoted the highest enzymatic activity. The exception was BKPSGII® (K. alvarezii X Sargassum sp.) where the influence of Sargassum sp. resulted in higher peroxidase activity (4.48 Δab600 mg P−1 min−1) in the leaves, 10 DAI. Both the red seaweed K. alvarezii and the brown alga Sargassum sp. promoted activities of β-1,3-glucanase, peroxidase and PAL.

“…Furthermore, β-glucan could be fermented by the colon microbiota and gives the end products of SCFA (mainly acetic, propionic and butyric acids), of which propionic acid plays a crucial role in hypocholesterolaemic activities with suppressing the activity of hydroxy methylglutaryl coenzyme A (HMG CoA), which is a rate-limiting enzyme during endogenous cholesterol synthesis (64)(65)(66) . In vitro, β-glucan could also act as an inhibitor of HMG-CoA and resulting in impairment of cholesterol biosynthetic pathway (67,68) . Clinical trials and reviews suggested that supplement of β-glucan could stimulate to increase the abundance of certain beneficial gut microbiota, such as Bifidobacterium and Lactobacillus (69,70) , and these bacterial genera are known to predominately contain bile salt hydrolase-positive species, which could modulate the host bile acid pool signature through deconjugation of conjugated bile acid.…”

β-glucan has been reported for its health benefits on blood lipids in hypercholesterolemic individuals for years. However, people has paid little attention to the effects in population with mildly hypercholesterolemic as well as the various delivering matrices of β-glucan. Our objective was to perform a meta-analysis to analyze the effects of β-glucan with different delivering matrices in mildly hypercholesterolemic individuals. After conducting a comprehensive search in Web of science, Pubmed, Scopus and Cochrane library, a total of 21 randomized controlled trials involving 1120 participants were identified to measure the pooled effect. The overall results indicated consuming in a doses of ≥3g/d of β-glucan for at least 3 weeks could significantly reduce TC (-0.27mmol/L, 95%CI: -0.33, -0.21, P<0.001) and LDL-c (-0.26mmol/L, 95%CI: -0.32, -0.20, P<0.001) compared with control group in mildly hypercholesterolemic individuals, while no significant difference was observed in TG (-0.03mmol/L, 95%CI: -0.11, 0.06, P=0.521) and HDL-c (0.01mmol/L, 95%CI: -0.03, 0.04, P=0.777). There was evidence for modest unexplained heterogeneity in the meta-analysis. In conclusion, β-glucan can significantly reduce risk factors like TC and LDL-c for CVD in mildly hypercholesterolemic individuals, furthermore, it appears that the effects of food matrices with both ‘solid-products’ and ‘liquid-products’ where β-glucan was incorporated into ranked as the best way to exert its beneficial properties, while ‘liquid’ and ‘solid’ products were ranked as the second, third position respectively.

“…It was demonstrated that the UAE sample has better antioxidant activities compared with other extraction methods (SBWE, UAE). Morales et al [ 57 ] have found UAE or SBWE (200 °C, 11.7 MPa) were more effective to obtain β-glucan enriched fractions from shiitake mushrooms. They revealed that a combination of UAE + SBWE extracts showed larger glucose levels and lower mannose and galactose residues than the other extractions, suggesting certain extraction specificity towards β-glucans.…”

Subcritical Water Extraction of Natural Products

et al. 2021

Subcritical water refers to high-temperature and high-pressure water. A unique and useful characteristic of subcritical water is that its polarity can be dramatically decreased with increasing temperature. Therefore, subcritical water can behave similar to methanol or ethanol. This makes subcritical water a green extraction fluid used for a variety of organic species. This review focuses on the subcritical water extraction (SBWE) of natural products. The extracted materials include medicinal and seasoning herbs, vegetables, fruits, food by-products, algae, shrubs, tea leaves, grains, and seeds. A wide range of natural products such as alkaloids, carbohydrates, essential oil, flavonoids, glycosides, lignans, organic acids, polyphenolics, quinones, steroids, and terpenes have been extracted using subcritical water. Various SBWE systems and their advantages and drawbacks have also been discussed in this review. In addition, we have reviewed co-solvents including ethanol, methanol, salts, and ionic liquids used to assist SBWE. Other extraction techniques such as microwave and sonication combined with SBWE are also covered in this review. It is very clear that temperature has the most significant effect on SBWE efficiency, and thus, it can be optimized. The optimal temperature ranges from 130 to 240 °C for extracting the natural products mentioned above. This review can help readers learn more about the SBWE technology, especially for readers with an interest in the field of green extraction of natural products. The major advantage of SBWE of natural products is that water is nontoxic, and therefore, it is more suitable for the extraction of herbs, vegetables, and fruits. Another advantage is that no liquid waste disposal is required after SBWE. Compared with organic solvents, subcritical water not only has advantages in ecology, economy, and safety, but also its density, ion product, and dielectric constant can be adjusted by temperature. These tunable properties allow subcritical water to carry out class selective extractions such as extracting polar compounds at lower temperatures and less polar ingredients at higher temperatures. SBWE can mimic the traditional herbal decoction for preparing herbal medication and with higher extraction efficiency. Since SBWE employs high-temperature and high-pressure, great caution is needed for safe operation. Another challenge for application of SBWE is potential organic degradation under high temperature conditions. We highly recommend conducting analyte stability checks when carrying out SBWE. For analytes with poor SBWE efficiency, a small number of organic modifiers such as ethanol, surfactants, or ionic liquids may be added.
