Abstract
Medicinal mushrooms, especially Ganoderma species, hold immense promise for the production of a wide range of bioactive compounds with various effects. The biochemical potential of indigenous fungal strains, specific to a region, could play a critical role in the continuous search for novel strains with superior activities on a global scale. This research focused on the ethanolic (EtOH) and hot-water (H2O) extracts of fruiting bodies of two wild-growing Ganoderma species: G. pfeifferi and G. resinaceum, with the aim of assessing their nutritional (total carbohydrate content-TCC) and mineral composition in relation to bioactive properties: antioxidant, antiproliferative and lipid-lowering. Atomic absorption spectrophotometry (AAS) revealed that G. pfeifferi is a promising source of minerals that are essential for numerous physiological functions in the human body like bone health and muscle and nerve function, with Ca (4.55 ± 0.41 mg/g d.w.) and Mg (1.33 ± 0.09 mg/g d.w.) being the most abundant macroelement present. Zn, Mn, and Cr were particularly notable, with concentrations ranging from 21.49 to 41.70 mg/kg d.w. The EtOH extract of G. pfeifferi demonstrated significantly elevated levels of TCC, essential macromolecules for energy and structural functions in the body, with higher quantities of all three standard carbohydrates detected in this type of extract. Similar to the revealed composition, the same species, G. pfeifferi, stood out as the most prominent antioxidant agent, with the H2O extract being stronger than EtOH in the ABTS assay (86.85 ± 0.67 mg TE/g d.w.), while the EtOH extract displayed the highest anti-OH• scavenging ability (IC50 = 0.18 ± 0.05 μg/mL) as well as the most notable reducing potential among all. The highest antiproliferative effect against the breast cancer cell line (MCF-7), were demonstrated by the H2O extracts from G. resinaceum with the most pronounced activity after 24 h (IC50 = 4.88 ± 0.50 μg/mL), which surpasses that of the standard compound, ellagic acid (IC50 = 33.94 ± 3.69 μg/mL). Administration of both Ganoderma extracts mitigated diabetic lipid disturbances and exhibited potential renal and hepatic protection in vivo on white Wistar rats by the preservation of kidney function parameters in G. resinaceum H2O pre-treatment (urea: 6.27 ± 0.64 mmol/L, creatinine: 50.00 ± 6.45 mmol/L) and the reduction in ALT levels (17.83 ± 3.25 U/L) compared to diabetic control groups treated with saline (urea: 46.98 ± 6.01 mmol/L, creatinine: 289.25 ± 73.87 mmol/L, and ALT: 60.17 ± 9.64 U/L). These results suggest that pre-treatment with G. resinaceum H2O extracts may have potential antidiabetic properties. In summary, detected microelements are vital for maintaining overall health, supporting metabolic processes, and protecting against various chronic diseases. Further research and dietary assessments could help determine the full potential and applications of the two underexplored Ganoderma species native to Serbia in nutrition and health supplements.

J Fungi (Basel) 2023; 10:21. [PMID: 38248931 PMCID: PMC10816940 DOI: 10.3390/jof10010021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/22/2023] [Accepted: 12/25/2023] [Indexed: 01/23/2024] Open
Abstract
The therapeutic effectiveness of current neurodegenerative disease treatments is still under debate because of problems with bioavailability and a range of side effects. Fungi, which are increasingly recognized as sources of natural antioxidants and acetylcholinesterase (AChE) enzyme inhibitors, may thus serve as potent neuroprotective agents. Previous studies have associated the anti-AChE and antioxidant activities of fungi mostly with polysaccharides and phenolic compounds, while other secondary metabolites such as polyamines (PAs) have been neglected. This study aimed to investigate eight edible and medicinal fungi from Serbia, marking the initial investigation into the neuroprotective capabilities of Postia caesia, Clitocybe odora, Clitopilus prunulus, and Morchella elata. Neuroprotective activity was examined using the Ellman assay, while the antioxidant capacity was tested by conducting DPPH, NO, ABTS, and FRAP tests. PA levels were determined by high-performance liquid chromatography (HPLC) coupled with fluorescent detection. Ganoderma applanatum and Lepista nuda exhibited the most robust anti-AChE (98.05 ± 0.83% and 99.94 ± 3.10%, respectively) and antioxidant activities, attributed to the synergistic effects of the total protein, total phenolic, and PA levels. Furthermore, P. caesia displayed significant AChE inhibition (88.21 ± 4.76%), primarily linked to the elevated spermidine (SPD) (62.98 ± 3.19 mg/kg d.w.) and putrescine (PUT) levels (55.87 ± 3.16 mg/kg d.w.). Our results highlight the need for thorough research to comprehend the intricate relationships between distinct fungus species and AChE inhibition. However, it is important to recognize that more research is required to identify the precise substances causing the reported inhibitory effects.

Abstract
Ganoderma species have been recognized as potential antimicrobial (AM) agents and have been used in traditional Chinese medicine (TCM) for a long time. The aim of this study is to examine the AM potential of autochthonous Ganoderma species (G. applanatum, G. lucidum, G. pfeifferi and G. resinaceum) from Serbia. The extraction of fungal material was prepared in different solvents (ethanol-EtOH, water-H2O, chloroform-CHCl3). Antibacterial activity (ABA) was determined using disk-diffusion, agar-well diffusion, and micro-dilution method, while for antifungal properties disk-diffusion and pour plate method were applied. Antiviral activity was tested on model DNA virus LK3 and determined by plaque assay. Statistical PCA analysis was applied for detection of correlation effects of phenolics and AM activities, while LC-MS/MS was performed for phenolics quantification. G. resinaceum CHCl3 extract expressed the most potent ABA against P. aeruginosa (MIC = 6.25 mg/mL), probably due to presence of flavonoids and 2,5-dihydroxybenzoic acid. Among H2O extracts, the highest ABA was determined for G. pfeifferi against both E. coli and S. aureus (21 and 19 mm, respectively). EtOH extracts of G. pfeifferi and G. resinaceum were the most effective against A. niger (23.8 and 20.15 mm, respectively), with special impact of phenolic acids and flavonoid isorhamnetin, while C. albicans showed the lowest susceptibility. The most potent antiviral inhibitor was G. lucidum (70.73% growth inhibition) due to the high amount of phenolic acids. To the best of our knowledge, this is the first report of a methodical AM profile of G. pfeifferi and G. resinaceum from the Balkan region including PCA analysis.

Abstract
Ganoderma species have been used in folk medicine against different illnesses and are characterized by producing a diversity of bioactive metabolites (triterpenoids, polysaccharides, flavonoids, and phenols) with numerous medicinal effects (anti-proliferative, antioxidant, anti-inflammatory, and antibacterial). This work aims to evaluate ethanolic extracts of fruiting bodies of Ganoderma oerstedii, G. weberianum, and G. subincrustatum strains from the Sonoran Desert in the anti-proliferative activity by the MTT assay on cancer cell lines; anti-inflammatory effect by quantifying nitric oxide (NO) production; antioxidant activity by DPPH, ABTS, and FRAP assays; total phenolic and flavonoid content by Folin-Ciocalteu and AlCl3 method, respectively; antibacterial activity by the broth microdilution method against Escherichia coli and Staphylococcus aureus. Extracts showed anti-proliferative activity with IC50 < 100 µg/mL on the cancer cell lines MDA-MB-231, A549, and HeLa, except G. subincrustatum extract with an IC50 > 100 µg/mL; anti-proliferative activity was not selective, being affected non-cancerous cell line ARPE-19. Extracts showed significant inhibition of NO release in cells stimulated by LPS, up to 60% with G. subincrustatum and G. oerstedii, and 47% with G. weberianum. All tested assays showed moderate antioxidant potential; the most active was G. lucium (control strain) with IC50 of 69 and 30 µg/mL by DPPH and ABTS respectively; and 271 µg Trolox equivalents/g by FRAP. Total phenols and flavonoids ranged from 38 to 56 mg GAE/g and 0.53 to 0.93 mg QE/g, respectively. A significant correlation was found between the antioxidant activities revealed by DPPH, ABTS, and FRAP with total phenol and flavonoid contents. Antibacterial activity was weak against S. aureus (MIC50 > 10 mg/mL). These results demonstrate that tested Ganoderma mushrooms have medicinal potential such as anti-inflammatory and anti-proliferative.

Abstract
OBJECTIVES Juglans regia L. is largely used by diabetic population, but its bark is scarcely investigated. The major aim of this study was to investigate the effect of the hydro-methanolic extract and fractions of J. regia L. barks on normoglycemic and diabetic rats through the evaluation of some biochemical parameters. METHODS Phenolic enriched extracts were investigated for their effect on normoglycemic and diabetic rats through the determination of fasting blood glucose levels in short- and long-term. As well as plasma total cholesterol, triglycerides, insulin, urea, creatinine, alanine amino transferase (ALT) and aspartate amino transferase (AST) levels were measured after 28 days of treatment. Furthermore, the phytochemical composition was assessed by standard methods. RESULTS Among the different extracts tested, the n-Butanol fraction presented the highest amounts of total phenolic, total flavonoids and flavonol contents (745 ± 0.6 mg GAE g-1, 162 ± 0.78 mg CE g-1 and 56.02 ± 0.92 mg QE g-1, respectively) and it found to be the most effective to decrease plasma total cholesterol, triglycerides and FGLs in treated diabetic rats in both short- and long-term treatment, mainly the dose 200 mg/kg after 28 days of treatment which found to be more effective than glibenclamide. This fraction also revealed pronounced improvement in liver and renal profiles. CONCLUSIONS J. regia L. barks had an important antidiabetic role similar to the reference glibenclamide. This may be related to the high contents of phenolic compounds.

Abstract
Alloxan is a chemical generally administered to rats to induce diabetes mellitus, and pharmaceutical industries test the efficacy of their diabetic products on these rats. Alloxan is in a redox cycle with dialuric acid; hence, direct estimation of alloxan may not represent the actual concentration of the same in a given matrix. Also, in recent times, alloxan is added to food materials, especially to the all-purpose flour (maida) to bring softness and white color to the flour. Hence, consumption of food items made from such flour could induce diabetic mellitus in individuals, making it imperative to develop an accurate estimation of alloxan in food items. Herein, a voltammetric-based technique is developed to quantify the alloxan in refined wheat flour (maida) using an unmodified glassy carbon electrode (GCE). The electrochemical method offers rapid sensing while the use of an unmodified GCE surface offers repeatability and reproducibility between measurements. First, alloxan is converted to its stable adduct alloxazine by the reaction with o-phenylenediamine. The alloxazine adduct is electrochemically active, and the concentration of alloxan is estimated as a function of alloxazine formed using the voltammetric technique. The common shortfall in alloxan detection mainly involves its short half-life (∼a minute) whereas the alloxazine adduct formed is stable over a period of time. Using the current approach, alloxan concentration ranging from 10 to 600 μM is detected with a sensitivity of 0.0116 μA/μM. A low limit of detection of 1.95 μM with a precision of 1.2% is achieved using the above method. Real sample analysis revealed the presence of alloxan in all-purpose flour (maida-refined wheat flour) and bread purchased from the local market to the values of 35.76 and 25.03 μM, respectively. The same is confirmed using the gold-standard colorimetric technique.

Abstract
Medicinal mushrooms have tremendous potential in production of bioactive compounds with diverse bioactivities while the biochemical potential of some specific mushroom strains (autochthonous for the region) in production of specific bioactive agents may be of the main importance in a continuous search for novel strains with supreme activities all over the world. In this study, the ethanolic (EtOH) and water (H2 O) extracts of wild-growing polypore mushroom species were investigated: Trametes versicolor (L.) Lloyd and Stereum subtomentosum Pouzar. This study was designed to determine total phenol (TP), flavonoid (TF) and protein content (TPR) as well as LC/MS/MS phenolic profile related to in vitro antioxidant, antiproliferative (MTT assay) (AP) and DNA fragmentation properties. The H2 O extracts expressed better antioxidant scavenging potential than EtOH showing the highest activity for the T. versicolor (IC50 =5.6 μg/mL, IC50 =0.6 μg/mL for DPPH. and OH. , respectively) while O2 .- activity achieved the best activity for S. subtomentosum (IC50 =4.1 μg/mL). In contrary, the highest AP activity was obtained for the EtOH extracts of S. subtomentosum (IC50 =141.1 μg/mL). The EtOH extracts of both species showed the highest TP, TF and TPR content. Obtained results of DNA degradation indicate genotoxicity potential of the extracts at high concentration. The LC/MS/MS detection showed that the majority of analyzed extracts contained phenolic acids, p-hydroxybenzoic and protocatechuic acid. The obtained results suggest that analyzed medicinal mushroom species, T. versicolor and S. subtomentosum, could be of potential interest as new sources of strong natural antioxidants as well as antiproliferative agents in the future.
