“…The result of total flavonoid content determination indicated that G. lucidum growing in Morocco is a rich source of this important antioxidant compound with a value of 60.55 mg of CEs/g of dme, which was quite a lot higher than that found in the Algerian study [ 46 ]. Two studies from Pakistan and Turkey reported high amounts of total flavonoids in wild G. lucidum , with values of 73.02–217 mg CEs/g in the dry extract [ 42 , 47 ].…”

“…Likewise, our methanolic extract exhibited higher antiradical capacity than those of several studies from different countries, including Portugal, Ghana, Serbia China, Montenegro and Turkey, with EC 50 values ranging between 0.73 and 7.49 mg/mL [ 34 , 37 , 48 , 53 , 57 ]. Kebaili et al investigated Algerian G. lucidum and found that ethyl acetate fraction (IC 50 = 28 µg/mL) had better antioxidant properties than butane (61 µg/mL) and chloroform fractions (129 µg/mL) [ 46 ]. The ethanolic extract from Philippines fungi gave the best antioxidant activity, with EC 50 equal to 10.69 µg/mL [ 71 ].…”

“…Previously, two studies tested the reducing power of G. lucidum from Portugal, resulting in EC 50 values of 150 and 620 µg/mL for ethanolic [ 57 ] and phenolic [ 43 ] extracts, respectively. Furthermore, Kebaili et al recorded that ethyl acetate extract was more effective in reducing power than chloroform and butanoic extract of Algerian fungi, with IC 50 = 22, 85 and 108 µg/mL, respectively [ 46 ].…”

Ganoderma lucidum is an extensively famous medicinal mushroom distributed worldwide. Despite being widely grown in Moroccan forests, there are no studies on its nutritional, nutraceutical and pharmaceutical values. Herein, the objective of this study was to investigate the chemical characterization and antimicrobial properties of G. lucidum methanolic extract. Total phenolic, flavonoid, tannin, ascorbic acid and carotenoid contents were determined by spectrophotometry. The results revealed that the most prevalent bioactive compounds were phenolics and flavonoids, with total values of 154.60 mg GAE/g of dry methanolic extract (dme) and 60.55 mg CE/mg of dme, respectively. A GC–MS analysis identified 80 biologically active molecules, which were mainly divided into the following major groups: sugars (49.49%), organic acids (8.89%), fatty acids (7.75%), amino acids (7.44%), steroids (7.32%), polyphenols (5.92%), and others (13.16%). Additionally, 22 individual phenolic compounds were identified and quantified using HPLC–MS, with emphasis on kaempferol (1714 µg/g of dry weight (dw)), apigenin (1955 µg/g dw) and quercetin (947.2 µg/g dw). The methanolic extract of G. lucidum indicated strong antioxidant capacity by means of the following: DPPH radical-scavenging activity (53.7 µg/mL), β-carotene/linoleate assay (43.75 µg/mL), and reducing power assay (76.62 µg/mL). Furthermore, the extract exhibited potent antimicrobial properties against seven human pathogenic microorganisms, including two bacteria and five fungal strains, at concentrations ranging from 1 to 16 mg/mL. The most sensitive pathogen was Epidermophyton floccosum (MIC = MFC = 1 mg/mL), while Aspergillus fumigatus was the most resistant one (MIC = 16 mg/mL and MFC ≥ 16 mg/mL). Overall, our findings demonstrated valuable nutritional and bioactive compound attributes, and potent antioxidant and antimicrobial properties, of G. lucidum growing in Moroccan forests. Moreover, these findings suggest that the Moroccan mushroom can be extremely useful for the food and medicinal industries to positively affect socioeconomic status.

“…According to our findings, the greater dose of MEGL had the most CNS depressive impact, and it is presumed that these effects may be mediated by the inhibition of the postsynaptic interpretation of GABA receptor. G. lucidum also contains phytochemicals such as triterpenes, flavonoids, phenolic compounds, glycoproteins, proteoglycan, and polysaccharide [ [51] , [52] , [53] , [54] ]. Thus, interactions between these phytochemicals and neurotransmitters linked to depressive-like behavior are most likely to be responsible for MEGL's antidepressant and anxiolytic effectiveness.…”

The Ganoderma Lucidum is known as a promising medicine that contains a high amount of antioxidants and calcium. The selection of appropriate drying process methods in food science has a chief role to reach the best final characteristics. This study was aimed to investigate the effects of air velocity and temperature in the convective dryer, sample distance, and infrared power in infrared dryers on the drying kinetics and quality of Ganoderma lucidum slices. In addition, Response Surface Methodology based on central composition design was used to optimize and analyze drying conditions. The ranges of temperature and air velocity were 40 to 60 C° and 0.5 to 1.5 m/s, respectively in the convective drying process while the range of distance and infrared power was 4 to 16 cm and 500 to 1500 W, respectively in the infrared drying process. It is worth mentioning that antioxidant and calcium contents were greatly enhanced during the drying procedures. Moreover, the values of the total color difference ranged between 8.21 and 19.66 for convective dryer and 8.14 and 28.85 for infrared dryer. A kinetic study indicated that dried samples by infrared dryer could rapidly reach equilibrium moisture content due to exposure to IR radiation. Consequently, the results indicated that the infrared dryer has better performance than the convective dryer regarding drying time, energy consumption, and amount of calcium and antioxidant.
