The isolated compound was L-(+)-ergothioneine, where the purity (95%) and antioxidant activity of were confirmed by chromatography and HPLC-DPPH assay, while the structure of this compound was elucidated from HR ESI-MS and NMR data. This method proved to be very efficient for the recognition and isolation of highly polar free radical inhibitors from fungi extracts, and is also applicable for the purification of highly polar compounds from other sources. Destruction of assembly structures has been identified as a major cause for ac
