Abstract
Eritadenine, a potent compound of hypocholesterolemic activity, was investigated in relation to its content in domestic cultivars and wild types of shiitake (Lentinula edodes). Eighteens strains of shiitake were tested for the quantification of eritadenine by LC-MS/MS analysis. Among the strains, wild type-40 was highest as the content was 3.912 mg/g. Also, Soohyangko was 3.352mg/g, Sanlim No. 9 3.008mg/g, Chunbaegko 2.832 mg/g, Gaeulhyang and KFRI 675 both 2.792 mg/g as high-content strains. Soohyangko and Chunbaegko are applied strains for registration in 2010. Soohyangko is high-temperature type with concentrated fruiting, and 90% of production occurs in the first year, thus, recovery of cost is very fast. Chunbaegko is mid-temperature type with concentrated flushing, and produces "hwago", the best quality, in spring. Wild type-40 is excellent in productivity and is prepared for registration. Wild type-40 could be used as parent strain to make new strain with high eritadenine content.
