Abstract
Garlic and ginger are well known as safe alternatives to traditional therapies. Limited information exists regarding antioxidant, antibacterial and antiviral capabilities of the combination of ginger and garlic. Standard methodologies were employed to determine the phytochemical compositions. Antioxidant activities were evaluated through DPPH and FRAP assays. Notably, in DPPH assay, combination of ginger and garlic extracts displayed significantly higher (85.44%, p < 0.005) antioxidant activity even at lower concentrations (6 mg/ml) compared to ginger and garlic extracts alone. Similar findings were observed for FRAP assay. At low concentration of extracts (25 µg/ml), combination of ginger and garlic exhibited significant (p < 0.005) increase in reducing activity (51%) compared to ginger or garlic extracts alone. Significant antibacterial and antiviral activities were exhibited by the combination of both ginger and garlic extracts as compared to ginger and garlic extracts alone. The combined effect of garlic and ginger exhibited a synergistic effect in bacterial and viral growth inhibition. These findings suggest that the diverse phytochemical compositions of the ginger and garlic varieties contribute to their strong antioxidant properties, potentially positioning them as valuable therapeutics for bacterial and viral infections. Further analysis will be required for their widespread utilization and pharmaceutical applications.

Antioxidant activity of Phellinus igniarius fermentation mycelia contributions of different solvent extractions and their inhibitory effect on α-amylase. Heliyon 2024; 10:e23370. [PMID: 38234922 PMCID: PMC10792562 DOI: 10.1016/j.heliyon.2023.e23370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 11/30/2023] [Accepted: 12/01/2023] [Indexed: 01/19/2024] Open
Abstract
Phellinus spp. have historically been used as traditional medicines to treat various diseases owing to their antioxidant, antitumor, and antidiabetic activities. Polysaccharides exhibit antidiabetic activity. In the present study, the polysaccharide contents of four Phellinus strains were compared. Phellinus igniarius QB72 possessed higher polysaccharide production, stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, and α-amylase inhibitory activity. The three polysaccharides were sequentially extracted and partially purified from the fermentation mycelia using hot water, 1 % (NH4)2C2O4, and 1.25 M NaOH. Hot water extract polysaccharides exhibited higher DPPH radical scavenging and strong inhibitory activity against α-amylase with an IC50 value of 6.84 ± 0.37 mg/mL. The carbohydrate content of A1 (approximately 17457 Da) was approximately 88.28 %. The α-amylase inhibitory activity IC50 was decreased (3.178 ± 0.187 mg/mL) after DEAE water elution. P. igniarius QB72 hot-water extracts of partially purified polysaccharides have great potential as α-amylase inhibitors in food and medication-assisted additives.

Abstract
To fully utilize Phellinus igniarius fermentation mycelia, the present study investigated the in vitro antioxidant and α-amylase inhibitory properties of four Ph. igniarius strains. Organic solvents were used to extract fatty acids, phenolics, and flavonoids from the selected mushrooms. The composition and bioactivity of the extracts were evaluated. The lipid yield obtained using petroleum ether (7.1%) was higher than that obtained using 1:1 n-hex-ane+methanol (5.5%) or 2:1 dichloromethane+methanol (3.3%). The composition and relative content of saturated and unsaturated fatty acids in the petroleum ether extract were higher than those in other solvent extracts. Furthermore, ethyl acetate extracts had higher flavonoid and phenolic content and better antioxidant activity than other extracts; however, the 70% ethanol extracts had the best α-amylase inhibitory activity. The supernatant from the ethanol precipitation of aqueous and 1% (NH4)2C2O4 extracts could also be biocompound sources. This comparative study is the first highlighting the in vitro antioxidant and α-amylase inhibitory properties of the four strains of Ph. igniarius extracts prepared using different organic solvents, which makes the investigated species and extracts promising for biological application.

Abstract
The human uses of mushrooms and cultured mycelium products for nutrition and medicine are detailed and supported by available human studies, which in many cases are clinical trials published in peer-reviewed journals. The major medically active immunomodulating compounds in the cell walls-chitin, beta-glucans, and glycoproteins, as well as lower weight molecules-nitrogen-containing compounds, phenolics, and terpenes-are discussed in relation to their current clinical uses. The nutritional content and foods derived from mushrooms, particularly related to their medical benefits, are discussed. High-quality major nutrients such as the high amounts of complete protein and prebiotic fibers found in edible and medicinal fungi and their products are presented. Mushrooms contain the highest amount of valuable medicinal fiber, while dried fruiting bodies of some fungi have up to 80% prebiotic fiber. These fibers are particularly complex and are not broken down in the upper gut, so they can diversify the microbiome and increase the most beneficial species, leading to better immune regulation and increasing normalizing levels of crucial neurotransmitters like serotonin and dopamine. Since the growth of medicinal mushroom products is expanding rapidly worldwide, attention is placed on reviewing important aspects of mushroom and mycelium cultivation and quality issues relating to adulteration, substitution, and purity and for maximizing medicinal potency. Common questions surrounding medicinal mushroom products in the marketplace, particularly the healing potential of fungal mycelium compared with fruiting bodies, extraction methods, and the use of fillers in products, are all explored, and many points are supported by the literature.
