Macroscopic fungi on Caucasian alder wood (Alnus subcordata) were identified and tested as a source of betulin and betulinic acid (the most important metabolites of the Betulaceae family) to evaluate levels of phenols, flavonoids and antioxidant activity. Ganoderma applanatum, Lenzites betulina, Trichaptum biforme, Rigidoporus ulamrius, Fomes fomentarius, Schizophyllum commune, Auricularia mesenterica, and Trametes versicolor were among those identified, and they differed significantly in the level of betulin and betulinic acid and phenols, flavonoids and antioxidant properties in fungal tissues extracted with methanol and with ethanol (p ≤ 0.01). G. applanatum had the most betulin (3.642%) and S. commune the most betulinic acid (1.413%). All tested fungi had high antioxidant activity, and L. betulina had the highest (97.775%). The highest amounts of phenol (719.993 mg mL⁻¹) and flavonoids (361.403 mg mL⁻¹) were found in the ethanolic extract from G. applanatum. Considering the results of this study and the low cost and convenient access to these fungi, they should be good sources for producing different drugs.

确定了高加索al木（Alnus subcordata）上的宏观真菌，并将其作为桦木素和桦木酸（桦木科最重要的代谢产物）的来源进行测试，以评估酚，类黄酮的水平和抗氧化活性。树舌灵芝，Lenzites betulina，Trichaptum biforme，硬孔菌属ulamrius，木蹄层孔菌，裂褶菌，木耳肠系膜和云芝是那些识别中，并且它们在桦木醇和桦木酸和酚类，黄酮类化合物和抗氧化性能在用甲醇提取真菌组织中的水平，并用乙醇（显著差异p  ≤0.01）。G.舌有最桦木醇（3.642％）和S.公社最桦木酸（1.413％）。所有测试的真菌均具有较高的抗氧化活性，其中白桦乳杆菌的抗氧化活性最高（97.775％）。在青G的乙醇提取物中发现了最高的苯酚（719.993 mg mL ^-1）和类黄酮（361.403 mg mL ^-1）。。考虑到这项研究的结果以及低成本和方便地获得这些真菌，它们应该是生产不同药物的良好来源。
