Mushrooms are important sources of natural bioactive compounds. Pleurotus eryngii (DC.) Quél is recognized for its organoleptic quality and health effects, being extensively commercialized. Instead, Suillus bellinii (Inzenga) Watling is an ectomycorrhizal symbiont, whose main properties were scarcely reported. Considering current trends, the mycelia and the culture media of these mushrooms might be potential sources of bioactive compounds. Accordingly, P. eryngii and S. bellinii were studied for their phenolic acids and sterols, antioxidant capacity, anti-inflammatory effect and anti-proliferative activity. S. bellinii mycelia showed higher contents of ergosterol and phenolic compounds (also higher in its fruiting body) and stronger antioxidant activity than P. eryngii. Conversely, P. eryngii mycelia showed anti-inflammatory (absent in S. bellinii mycelia) and a cytotoxicity similar (sometimes superior) to its fruiting bodies, contrarily to S. bellinii. Furthermore, the assayed species showed differences in the growth rate and produced mycelia, which should be considered in further applications.
蘑菇是天然生物活性化合物的重要来源。杏鲍菇因其感官品质和健康功效而闻名，并已广泛商业化。相反，贝氏乳牛肝菌是一种外生菌根共生体，其主要特性鲜有报道。考虑到当前的趋势，这些蘑菇的菌丝体和培养基可能是生物活性化合物的潜在来源。因此，对杏鲍菇和贝氏乳牛肝菌的酚酸和甾醇、抗氧化能力、抗炎作用和抗增殖活性进行了研究。贝氏乳牛肝菌菌丝体的麦角甾醇和酚类化合物含量更高（其子实体中含量也更高），抗氧化活性比杏鲍菇更强。相反，杏鲍菇菌丝体具有抗炎作用（贝氏乳牛肝菌菌丝体中没有），细胞毒性与其子实体相似（有时更强），这与贝氏乳牛肝菌不同。此外，所检测的物种在生长速率和产生的菌丝体方面存在差异，在进一步应用中应予以考虑。
