ABSTRACT Medicinal Ganoderma mushrooms have long tradition in Asia, and recently they began to be consumed in Europe as well. Among hundreds of Ganoderma species, only a few of them are intensively investigated, i.e., G. lucidum and G. applanatum, whereas the chemistry and bioactivities of the other species, especially of European origin, still remain unknown. This study comprises detailed chemical analysis of two Ganoderma species growing wild in Turkey, G. pfeifferi and G. carnosum. Metal composition of both species shows high concentrations of biogenic metals. Phenolic composition of the isolated extracts of G. carnosum and G. pfeifferi shows that these species are rich in simple phenolic acids, such as 2,5-dihydroxybenzoic acid and vanillic acid, but also in flavonoids. These compounds are found to be carriers of the antioxidant activity but also enzyme inhibition activity of the analyzed extracts. Overall results indicate that these two Ganoderma species have strong potential to be used for medicinal purposes.

Ganoderma carnosum 和 Ganoderma pfeifferi：金属浓度、酚类含量和生物活性

摘要 药用灵芝在亚洲有着悠久的传统，最近它们也开始在欧洲消费。在数百种灵芝物种中，只有少数被深入研究，即灵芝和 G. applanatum，而其他物种，尤其是欧洲起源的物种的化学和生物活性仍然未知。这项研究包括对土耳其野生两种灵芝物种 G. pfeifferi 和 G. carnosum 的详细化学分析。两种物种的金属成分都显示出高浓度的生物金属。G. carnosum 和 G. pfeifferi 的分离提取物的酚类成分表明，这些物种富含简单的酚酸，如 2,5-二羟基苯甲酸和香草酸，但也富含类黄酮。发现这些化合物是所分析提取物的抗氧化活性和酶抑制活性的载体。总体结果表明，这两种灵芝物种具有强大的药用潜力。
