Infectious disease is one of the major threats to humans and it is the second leading cause of death worldwide. Edible mushrooms have many nutritional and medicinal values to human health. The medicinal properties of edible mushroom extract in inhibiting pathogenic microorganisms had advantages over the use of chemically synthetic antimicrobial compounds due to less unwanted side effects and can combat microbial resistance. This study hypothesized that the polarity affects the extraction quality of Hericium erinaceus fruiting bodies which was prepared and subsequently affects its activity as an antimicrobial against six tested microorganisms, including MRSA, and Streptococcus mutans, Enterobacter cloaca, Salmonella typhimurium, and Candida lipolytica; antiviral against Hepatitis A virus (HAV) virus; antioxidant using 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay; and anti-inflammatory potential. So, the mushroom was quantitatively evaluated to assess its content of flavonoids, alkaloids, tannins, saponins, carbohydrates, protein, nitrogen, and oil. The current research clarified here that aquatic extract has a significant activity as an antioxidant (IC = 53.7 µg/mL) and antiviral (IC = 24.97 µg/mL), while ethyl acetate extract showed a reasonable antimicrobial activity rather than all tested extract against tested microorganisms. Unfortunately, all extracts under investigation possess low anti-inflammatory action according to the adopting protocol. The superior results of both water and ethyl acetate extracts were later investigated by HPTLC and GC-MS for preliminary prediction of the chemical constitution of those extracts. H. erinaceus mushroom succeeded to establish promising antimicrobial, antiviral, and antioxidant activities while it has low anti-inflammatory activity. Both HPTLC and GC-MS could identify the chemical constituents of the mushroom crude extract.
传染病是对人类的主要威胁之一,是全球第二大死因。食用菌对人类健康具有多种营养和药用价值。食用菌提取物抑制病原微生物的药用特性优于使用化学合成抗菌化合物,因为其副作用较小,且能对抗微生物耐药性。本研究假设极性会影响猴头菇子实体的提取质量,进而影响其对包括耐甲氧西林金黄色葡萄球菌、变形链球菌、阴沟肠杆菌、鼠伤寒沙门氏菌和解脂念珠菌在内的六种受试微生物的抗菌活性;对甲型肝炎病毒(HAV)的抗病毒活性;使用2,2-二苯基-1-苦基肼(DPPH)自由基清除试验的抗氧化活性;以及抗炎潜力。因此,对该蘑菇进行了定量评估,以测定其黄酮类、生物碱、单宁、皂苷、碳水化合物、蛋白质、氮和油的含量。本研究表明,水提取物具有显著的抗氧化活性(IC = 53.7 µg/mL)和抗病毒活性(IC = 24.97 µg/mL),而乙酸乙酯提取物对受试微生物的抗菌活性优于所有受试提取物。遗憾的是,根据所采用的方案,所有受试提取物的抗炎作用均较弱。随后通过高效薄层色谱法(HPTLC)和气相色谱-质谱联用仪(GC-MS)对水提取物和乙酸乙酯提取物的优异结果进行了研究,以初步预测这些提取物的化学成分。猴头菇成功展现出了有前景的抗菌、抗病毒和抗氧化活性,但其抗炎活性较低。HPTLC和GC-MS均可鉴定出该蘑菇粗提物的化学成分。
