The content of two groups of compounds with biological activity (non-hallucinogenic indole compounds and free phenolic acids) were analyzed in extracts of fruiting bodies of four species of Phellinus: P. igniarius, P. pini, P. pomaceus and P. robustus. The presence of indole compounds in methanolic extracts was analyzed by high-performance liquid chromatography and thin-layer chromatography coupled with densitometric detection. Three metabolites (serotonin, tryptamine, and L-tryptophan) were identified. The contents of individual indole compounds ranged from 1.70 (tryptamine in P. robustus) to 8.32 mg  100 g-1 dry weight (L-tryptophan in P. robustus). Four free phenolic acids were detected in methanolic extracts by the HPLC method. The total content ranged from 9.9 mg  100 g-1 DW (P. igniarius) to 32.5 mg  100 g-1 DW (P. robustus).

White Agaricus bisporus is both the most popular and the most commonly eaten edible mushroom species in the world. It is popular not only because of its taste, but also due to its high level of nutrients: dietary fi ber (chitin), essential, semi-essential amino acids, unsaturated fatty acids including linoleic and linolenic acids, easily digestible proteins, sterols, phenolic and indole compounds, and vitamins − especially provitamin D 2 and B 1 , B 2 , B 6 , B 7 , and C. Fruiting bodies of A. bisporus have antioxidant, antibacterial, anti-infl ammatory, antitumor, and immunomodulatory activity. The presence of antioxidant ergothioneine (which also displays the antimutagenic, chemo-and radioprotective activity) is also noteworthy. A. bisporus also contains derivatives of benzoquinone, a substance which belongs to the group of antibiotics. Studies of tyrosinase isolated from this species show its very high similarity to human tyrosinase. This points directly to the fact that this species could be a rich source of tyrosinase used for medicinal and cosmetics purposes. A. bisporus is also a rich source of selenium, zinc and other elements such as magnesium, copper, iron, potassium, sodium, calcium, phosphorus, sulfur or manganese. In conclusion, the presence of these compounds and elements with biological activity in fruiting bodies of A. bisporus confi rms their nutraceutical and medicinal properties.

The use of herbs or their parts: leaves, roots, rhizomes, flowers, seeds, natural strains, as well as extracts or isolated metabolites is becoming more and more popular. Natural remedies not only act prophylactically, but also help to alleviate symptoms of many diseases and enhance the overall functioning of the internal organs. Many raw materials of natural origin plays a role in treatment of health problems, and also in case of serious diseases such as depression. Depression (affective disorder) now affects about 10% of the population, but in next few years due to the development of civilization and increasing pace of life, the probable number of people suffering from this disease can grow rapidly. Natural raw materials such as Bacopa monnieri, Crocus sativus, Eleutherococcus senticosus, Griffonia simplicifolia, Hypericum perforatum, Sceletium tortuosum, Piper methysticum, Rhodiola rosea, Aspalathus linearis, Camellia sinensis, Ficus carica, Lycium chinense, Cuminum cyminum, Panax Ginseng can effectively assist the prevention and treatment of depression. Daily diet may also have positive effect in prevention of this disease. It was found that 5-hydroxy-L-tryptophan, L-tryptophan (which are precursors of serotonin in the CNS), omega-3 fatty acids and anthranilic acid (vitamin L1) are able to improve mood. L-Tryptophan, 5-hydroxy-L-tryptophan are present in the largest quantities in the fruiting bodies of edible mushrooms. Omega-3 fatty acids are found in the flesh of fish, walnuts, soybeans, beans and chicken egg protein, while the anthranilic acid is commonly found in plants.
