“…Preferable TPC and antioxidant activities of BD and BM were also similar to other Boletus species as previous studies. [3,4,11,[16][17][18] This study was revealed a lack of anticancer activities of BD and BM (maximum concentration = 100 µg/ml) against KB, MCF7, NCI-H187, HepG2 and CaCO 2 cell lines, and no cytotoxicity to normal cell also (Vero and HDFn cells). Anticancer activity of Boletus species was reported in literature review, however, its activity via immunmodulation and cell cycle arrest.…”

“…[16] They may also have strong antioxidant activity. [3,4,11,17,18] Boletus griseipurpureus Corner 1972 (Boletaceae) is a wild edible ectomycorrhizal mushroom, [19][20][21] rich in protein and low in fat. Thai local name is called "Hed Sa med," characterized by (1) Macroscopic features included pileus 3.0-6.0 cm across, convex to plane, gray to purple or light purple, surface covered with gray black short soft hairs when young; fresh white and firm when young, later softer, unchanging when injured; tube small and firm, pallid white when young, later pinkish to pale brown; and stipe 3.0-6.0 cm long, 1.5-3.0 cm across, purple, cylindrical to clavate, increasing in thickness to clavate toward the base, sometime with pale brown net at the apex.…”

Background: Boletus griseipurpureus Corner is a popular edible mushroom in the South of Thailand, which were rich in protein and very low in fat and possessed antibacterial. Aims: The aims of the study are to evaluate nutritive values and biological activities of B. griseipurpureus including antioxidant, anticancer, cytotoxicity and antimicrobial activities. Materials and Methods: Nutritive values of fresh mushrooms were analyzed mainly according to AOAC. Total phenolic content (TPC) and antioxidant activity of dichloromethane (BD) and methanol (BM) extracts were performed by of Folin-Ciocalteu reagent; DPPH radical, 2, 2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) cation radical scavenging assays and oxygen radical absorbance capacity. Anticancer activities of BD and BM were performed by resazurin microplate assay and tested with five cancer cell lines. Cytotoxicity of BD and BM were performed by same method and used normal cells. Antimicrobial activities of BD and BM against herpes simplex virus type 1 (HSV-1) and Mycobacterium tuberculosis were tested according to green fluorescent protein-based assay; Plasmodium falciparum was tested according to microculture radioisotope techniques; antibacterial and anti-Candida albicans tests were performed according to CLSI. Results: The relatively high content of copper, zinc, and selenium was contained in B. griseipurpureus when compared with Thai RDI values. Preferable TPC and antioxidant activities of BD and BM were also revealed. No anticancer activity (to KB, MCF7, NCI-H187, HepG2 and CaCO 2 cell lines) and cytotoxicity of (to Vero and human dermal fibroblasts, neonatal cells) from both extracts. Only, BM was inhibited HSV-1 (IC 50 = 41.67 µg/ml). Conclusions:The basidiomes of B. griseipurpureus were the relatively high content of antioxidant trace elements; and possessed antioxidant and HSV-1 inhibitory activities.

“…The antioxidant activities displayed by S. himantioides are even higher than those found in other in vitro studies of fungi (Cordyceps) exposed to UV radiation (45,46). Antioxidant properties of other Boletales fungi have been investigated in previous reports, but not under in vitro conditions (47)(48)(49)(50)(51). Melanin and carotenoid derivatives are a family of compounds with strong antioxidant activity (52).…”

Many fungi are thought to have developed morphological and physiological adaptations to cope with exposure to UV-B radiation, but in most species, such responses and their protective effects have not been explored. Here, we study the adaptive response to UV-B radiation in the widespread, saprotrophic fungus Serpula himantioides, frequently found colonizing coniferous wood in nature. We report the morphological and chemical responses of S. himantioides to controlled intensities of UV-B radiation, under in vitro culture conditions. Ultraviolet radiation induced a decrease in the growth rate of S. himantioides but did not cause gross morphological changes. Instead, we observed accumulation of pigments near the cell wall with increasing intensities of UV-B radiation. Nuclear magnetic resonance (NMR) and high-performance liquid chromatography-mass spectrometry (HPLC-MS) analyses revealed that xerocomic acid was the main pigment present, both before and after UV-B exposure, increasing from 7 mg/liter to 15 mg/liter after exposure. We show that xerocomic acid is a photoprotective metabolite with strong antioxidant abilities, as evidenced by DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt], and oxygen radical absorbance capacity (ORAC) assays. Finally, we assessed the capacity of xerocomic acid as a photoprotective agent on HEK293 cells and observed better photoprotective properties than those of β-carotene. Xerocomic acid is therefore a promising natural product for development as a UV-protective ingredient in cosmetic and pharmaceutical products. IMPORTANCE Our study shows the morphological and chemical responses of S. himantioides to controlled doses of UV-B radiation under in vitro culture conditions. We found that increased biosynthesis of xerocomic acid was the main strategy adopted by S. himantioides against UV-B radiation. Xerocomic acid showed strong antioxidant and photoprotective abilities, which has not previously been reported. Our results indicate that upon UV-B exposure, S. himantioides decreases its hyphal growth rate and uses this energy instead to increase the biosynthesis of xerocomic acid, which is allocated near the cell wall. This metabolic switch likely allows xerocomic acid to efficiently defend S. himantioides from UV radiation through its antioxidant and photoprotective properties. The findings further suggest that xerocomic acid is a promising candidate for development as a cosmetic ingredient to protect against UV radiation and should therefore be investigated in depth in the near future both in vitro and in vivo.

“…The highest values for B. regius extract (13.42 mg Fe/g dw) can be explained by their high level of phenolic compounds in comparison with other analysed mushrooms. Jaworska et al [26] determined the antioxidant activity of edible mushrooms, including B. edulis. Our result for B. edulis is in accordance with the value obtained in the mentioned paper.…”

The present study describes antioxidant properties of six wild mushrooms (Boletus edulis Bull., Boletus regius Krombh., Leccinum pseudoscaber Kallenb., Boletus impolitus Fr., Lactarius volemus Fr., and Lactarius deliciosus (L.) Gray) collected in Serbia. The antioxidant properties were assessed through the evaluation of the reducing power and radical scavenging ability of the samples. The Boletus regius sample revealed the best results in almost all antioxidant activity assays, with the highest reducing power and the highest scavenging activity, 33.0±0.1 mg TE/g dw in DPPH; 1.35±0.02 mg AAE/g dw in TRP; 13.42±0.08 mg Fe/g dw in FRAP; 37.5±0.2 mg TE/g dw in CUPRAC; 243.6±5.1 mg GAE/g dw in TPC. On the contrary, Lactarius volemus showed the lowest antioxidant activity. The results indicate that the analyzed wild mushroom species possess reductive capabilities, and they could be a potential source of antioxidants. The study was raised to the next level using a chemometric analysis, a principal component analysis to display the correlation between the antioxidant activity and different mushroom species.
