Abstract

has been extensively studied for its valuable medicinal importance. In this study, the artificial cultivation of strain Philippine in different culture media, including sawdust substrate, was performed and optimized on the Potato Dextrose Agar (PDA) media. Phytochemical, antibacterial, and antioxidant analyses were performed and compared between the ethanol extracts prepared from two different cultures (fruit from synthetic log culture and mycelia from PDA media culture). Both the 200 mg/mL and 100 mg/mL concentrations of extracts inhibited all the tested bacteria, and the results were promising than the corresponding control using antibiotics. The fruit extract showed higher antioxidant potential (150.6 ± 56.92 mg ascorbic acid equivalent/g extract) than mycelial extract (144.28 ± 81.72 mg ascorbic acid equivalent/g extract). The results indicate that fruiting bodies of cultivated in a complex dust medium possess higher antioxidant properties than mycelia culture, which can be further explored for therapeutic applications.

摘要

因其重要的药用价值而受到广泛研究。在本研究中,在包括木屑基质在内的不同培养基中对菲律宾菌株进行了人工培养,并在马铃薯葡萄糖琼脂(PDA)培养基上进行了优化。对从两种不同培养物(合成原木培养的果实和PDA培养基培养的菌丝体)制备的乙醇提取物进行了植物化学、抗菌和抗氧化分析并进行比较。提取物的200mg/mL和100mg/mL浓度均抑制了所有测试细菌,结果比使用抗生素的相应对照更有前景。果实提取物显示出比菌丝体提取物更高的抗氧化潜力(150.6±56.92mg抗坏血酸当量/g提取物)(144.28±81.72mg抗坏血酸当量/g提取物)。结果表明,在复杂粉尘培养基中培养的子实体比菌丝体培养物具有更高的抗氧化性能,可进一步探索其治疗应用。
