Abstract. Daba GM, Elkhateeb WA, El-Dien AN, Ahmed EF, El Hagrassi AM Fayad W, Wen TC. 2020. Therapeutic potentials of n-hexane extracts of the three medicinal mushrooms regarding their anti-colon cancer, antioxidant, and hypocholesterolemic capabilities. Biodiversitas 21: 2437-2445. Evaluating in vitro biological activities of the medicinal mushrooms Hericium erinaceus, Metacordyceps neogunnii, and Dictyophora indusiata n-hexane extracts revealed their capabilities as promising therapeutic sources. By assessing their DPPH radical scavenging activities, D. indusiata extract exhibited the highest antioxidant activity (87.8±1.2%) followed by H. erinaceus, then M. neogunnii 84.9±1.6%, and 77.3±1.3%, respectively. On the other hand, M. neogunnii extract exerted promising anti-colon cancer (68.6±3.6% cytotoxicity) against HCT116 human colon cancer cell lines at concentration 100 ?g/mL, whereas H. erinaceus and D. indusiata extracts exhibited weaker cytotoxic effects (18.3±1.7%, and 19.3±3.2%, respectively) using the same concentration. Investigating cholesterol reduction activities (CRA%) of the extracts revealed that activity depends on both extract concentration and incubation period. After 96 h of incubation at room temperature, all extracts exerted potent in vitro hypocholesterolemic activities (100±0% reduction in cholesterol concentration). Performing GC-Ms analyses on the extracts revealed presence of 22 compounds in D. indusiata extract, while 29 compounds were detected in M. neogunnii extract, and 33 in H. erinaceus extract. Most of compounds were esters of fatty acids. Results in this study encourage using these mushrooms as functional foods, and highlight the need for conducting further in vivo studies to support their use in pharmaceutical industry.

Abstract. Elkhateeb WA, Daba GM, Elnahas MO, Thomas PW, Emam M. 2020. Metabolic profile and skin-related bioactivities of Cerioporus squamosus hydromethanolic extract. Biodiversitas 21: 4732-4740.  Being a functional food capable of showing nutritional as well as medicinal properties have great attention. Mushrooms have been proven as leading targets in this field. For this purpose, the edible mushroom Cerioporus squamosus was investigated in this study to evaluate the in vitro skin-related bioactivities of its hydromethanolic extract in terms of enhancing wound healing, and human skin cancer suppression capabilities. Treatment of fibroblast cells (BJ-1) with the hydromethanolic extract of this mushroom at 50 µg/mL enhanced cell migration rates by 71.7% after 24 h of exposure to the extract. Moreover, the same extract exhibited a promising impact on human skin cancer using an epidermoid carcinoma cell line (A431). The gradual increase in C. squamosus hydromethanolic extract concentration caused gradual decrease in the A431 cell viability and proliferation. Maximum effect on reducing the cell viability was obtained at a concentration of 100 µg/mL, where cell viability was 3.7%, and recorded IC50 was 52.6 µg/mL. The metabolic profile of the extract was analyzed by GC-MS, which was performed on its silylated metabolites. Nineteen compounds were detected including sugar alcohols, amino acids, fatty and organic acids. Promising results of this mushroom extract encourage conducting further steps towards using this mushroom as a functional food showing promising bioactivities.
