【 摘 要 】

Ergothioneine (ERG) has long been recognized as a potent and stable antioxidant. In nature, ERG is synthesized only in fungi and mycobacteria, not in plants. The lifecycle ofGastrodia elata, an achlorophyllous orchid plant, is completely dependent on the presence of symbiotic fungi, particularlyArmillaria mellea. In this study, we report for the first time thatG. elataaccumulated ERG whose levels were correlated with the concentrations of ERG inA. mellea. The contents of ERG inG. elatawere significantly higher in actively developing tissues, such as seed capsules and newly growing corms, than in mature rhizomes. The ERG levels in rhizomes were significantly correlated with antioxidant capacities and were quantitatively comparable to the previously established major pharmacological components inG. elata. These results indicated that ERG is a newly found functional substance inG. elata, which may be responsible for the beneficial health effects ofG. elataon various human diseases.
