“…The antioxidant potential of many wild mushrooms in Asia has been correlated with total phenolics (Cheung and Cheung 2005; Lo and Cheung 2005). Interestingly, pressure-cooking resulted in significant increase in total phenolics ( p < 0.05) in A. hygrometricus , while it was opposite for tannins ( p < 0.01) (Figure 2(a,b)).…”

The wild mushroom Astraeus hygrometricus is a traditional delicacy during the monsoon season in South-western India. Bioactive principles and antioxidant potential of uncooked and pressure-cooked tender mushroom have been evaluated. Seven bioactive principles of mushroom (tannins, flavonoids, vitamin C, phytic acid, lycopene, β-carotene and trypsin inhibition) were significantly higher, while total phenolics content was significantly lower in uncooked than in cooked samples. Mushroom was devoid of L-DOPA, whereas only uncooked samples showed haemagglutinin activity against A+ blood group. The principal component analysis of uncooked mushroom showed only two bioactive principles clustered with two antioxidant properties, while in cooked mushroom five bioactive principles clustered with three antioxidant properties depicting the nutraceutical potential of cooked mushroom. Future studies should focus on appropriate thermal treatment, which retain maximum bioactive and antioxidant potential to combat health- and lifestyle-related ailments. The A. hygrometricus is ectomycorrhizal, conservation of its host tree species is utmost importance in improvement and expansion of its yield to sustain food security and economic gains of local tribals.

“…Mushrooms have become attractive as a functional food and as a source for the development of drugs and nutraceuticals (Barros et al, in press;Barros, Ferreira, Queiró s, Ferreira, & Baptista, 2007;Ferreira, Baptista, Vilas-Boas, & Barros, 2007;Cheung & Cheung, 2005;Mau, Chang, Huang, & Chen, 2004;Yanga, Linb, & Maub, 2002). In addition to dried mushrooms, alternative or substitute mushroom products are mycelia which could also be used as food and food-flavouring material, or in the formulation of nutraceuticals and functional foods.…”

Bioactive properties of the medicinal mushroom Leucopaxillus giganteus mycelium obtained in the presence of different nitrogen sources

et al. 2007

Leucopaxillus mushroom species are used in the chemical industry for extraction of clitocybin antibiotic and particularly the edible mushroom Leucopaxillus giganteus can be found in Northeast Portugal. Nevertheless, the production of its mycelium for pharmacological applications has not been explored. Herein, the mycelium obtained in the presence of four different nitrogen sources was investigated with regard to phenol production and antimicrobial and antioxidant properties. Phenol concentration increased along the growth time as a response to the oxidative stress and therefore free radical production. Although significant differences for mycelium growth between the nitrogen sources had not been observed, (NH 4 ) 2 HPO 4 proved to be the most appropriate to increase bioactive properties, leading to the highest phenol content and lowest EC 50 and MIC values. The antimicrobial capacity was screened against Gram positive and Gram negative bacteria, and fungi. The samples selectively inhibited the growth of Gram positive bacteria, Staphylococcus aureus being the most susceptible one. Gram negative bacteria and fungi were resistant to the extracts. Antioxidant activity was calculated by the reducing power assay, the scavenging effect on DPPH radicals, and hemolysis and lipid peroxidation inhibition. Significantly negative linear regressions were established between phenols/flavonoids contents, which increased along the mycelia growth time and antioxidant activity.

“…Medicinal mushrooms have a proven antioxidant effect and are therefore a suitable supplement to reduce the risk of oxidation. Many studies prove that they contain a number of potential natural antioxidants (Cheung et al, 2003;Cheung and Cheung, 2005;Lindequist et al, 2005) and are also a good source of phenols, flavonoids, carotenes and ascorbic acid (Froufe et al, 2009). They have an established history of use in the traditional medicine, particularly in Asia.…”

Effect of dietary linseed oil and Ganoderma lucidum or olive leaves supplementation on fatty acid composition and oxidative status of rabbits

et al. 2014

The aim of the present study was to evaluate the influence of natural antioxidant supplementation on the oxidative stress induced by a high proportion of polyunsaturated fatty acids (PUFA) in rabbit diets. Forty-eight SIKA rabbits (24 male, 24 female) were penned individually and after a 5-d adaptation period divided into 4 homogeneous groups (2.58±0.3 kg). The CONT-group received a diet with 60 g/kg palm fat, while the other 3 groups received a diet with 60 g/kg linseed oil which was either unsupplemented (CONT+) or supplemented with 10 g/kg of Ganoderma lucidum (REISHI) or 10 g/kg of olive leaves (OLIVE). Rabbits were euthanised at 102 d of age, 22 d after the start of the experiment. Live weight, weight gain, feed intake and feed conversion rate were recorded. The fatty acid composition of back (M. longissimus dorsi) and hind leg muscle (thigh muscle), adipose tissue (abdominal fat) and liver were determined. To evaluate the oxidative status of rabbits, the malondialdehyde (MDA) concentration in the plasma, liver and both muscles was measured. DNA damage in the leukocytes was measured. Linseed oil addition increased the PUFA ratio and decreased the proportion of saturated fatty acids in all tissues (P<0.001), with no detrimental effect on productive performance of rabbits compared to palm fat. Linseed oil also reduced n-6/n-3 PUFA ratio in all tissues (P<0.001). However, linseed oil addition increased the oxidative stress by increasing MDA concentrations in the liver and muscles (P<0.001), but did not affect the plasma MDA concentrations and the extent of DNA damage in the blood leukocytes compared to palm fat. Addition of olive leaves tended to decrease the concentration of MDA in the liver Addition of olive leaves tended to decrease the concentration of MDA in the liver compared to CONT+ (P=0.059), with no effect of Ganoderma lucidum.
