Phenolic compounds and antioxidant activity of fruiting body and spores of wild Ganoderma lucidum.

Ganoderma lucidum, a woody Basidiomycotina mushroom belonging to the family of Ganodermaceae of Polyporales, is not edible but extensively used in folk medicine for longevity and health promotion. Some pharmacological properties have been related to its capacity to lower the risk of cancer, liver, and heart diseases and to boost the immune system [1]. The beneficial health properties of Ganoderma are attributed to a wide variety of bioactive components present in the fruiting body, mycelium, and spores, mainly polysaccharides and triterpenes [2]. In the present work other bioactive molecules (phenolic compounds) were analysed by high-performance liquid chromatography coupled to photodiode array detection and mass spectrometry (HPLC-DAD-MS), in wild Ganoderma fruiting body and spores. Furthermore, the antioxidant properties were evaluated through radical scavenging effects, reducing power and lipid peroxidation inhibition (-carotene-linoleate and thiobarbituric acid reactive substances assays).
