“…The high content of alkaloids and tannins in PTR is also believed to be associated with the medicinal properties, such as antihypertensive, antiplasmodial, antidepressant, and analgesic activities . Various phenolic compounds, including protocatechuic acid, chlorogenic acid, syringic acid, ferulic acid, folic acid, 4-hydroxybenzaldehyde, 4-hydroxybenzoic acid, vanillic acid, ferulic acid, p -coumaric acid, caffeic acid, 2-allyl-5-ethoxy-4methoxyphenol, (9 E ,12 E ,15 E )-9,12,15-octadecatrien-1-ol, apigenin-4′,7-dimethyl ether, dehydroabietic acid, retusin, and sakuranin, have been identified in the sclerotium of PTR . , These phenolics can act as antioxidants and are promising candidates with high potential in treating and lowering the risk of various diseases …”

Pleurotus tuber-regium (PTR) is an edible specialty mushroom that has attracted growing interest recently because of its sensory attributes, high nutritional values, and important medicinal properties. PTR is rich in bioactive polysaccharides, proteins with essential amino acids, essential fatty acids, dietary fiber, minerals, and vitamins. Current studies have shown that the nutrients and bioactive ingredients of PTR contribute to their antitumor, antihypercholesterolemic, antihypertensive, antiobesity, hepatic-protective, antimicrobial, antioxidant, and prebiotic activities, indicating that PTR is a promising functional food and nutraceutical. In this review, the chemical constituents and physiological functions of PTR are summarized, which provide the scientific basis to support the further research and development of its application in the food and pharmaceutical industries.

In this study, we investigated in vitro the potential of Trichoderma harzianum to produce bioactive secondary metabolites that can be used as alternatives to synthetic compounds. The study focused on analyzing two extracts of T. harzianum using ethyl acetate and n-butanol solvents with different polarities. The extracts were examined using phytochemical analysis to determine the content of polyphenols, flavonoids, tannins, and alkaloids. Thin-layer chromatography (TLC) and Gas chromatography-mass spectroscopy (GC-MS) analysis were used to profile volatile organic metabolites (VOCs) present in the extracts. Furthermore, the extracts were tested for their antifungal ability using the poison food technique. For measuring antioxidant activity, the 1,1-diphenyl-2-picryl-hydrazyl (DPPH) test was used. Trichoderma harzianum was shown to have a significantly high content of tannins and alkaloids, with a noticeable difference between the two extracts. GC-MS analysis identified 33 potential compounds with numerous benefits that could be used in agriculture and the medicinal industry. Moreover, strong antifungal activity was identified against Sclerotinia sclerotiorum by 94.44%, Alternaria sp. by 77.04%, and Fusarium solani by 51.48; similarly, the IC50 of antioxidant activity was estimated for ethyl acetate extract by 71.47% and n-butanol extract by 56.01%. This leads to the conclusion that Trichoderma harzianum VOCs play a significant role as an antifungal and antioxidant agent when taking into account the advantageous bioactive chemicals noted in the extracts. However, to our knowledge, this is the first study in Algeria presenting detailed phytochemical analysis and GC-MS profiling of Trichoderma harzianum for two extracts, ethyl acetate and n-butanol.
