| concentrations of radiocesium and potassium in basidiomycetes collected in japan. | concentrations of 137cs, 134cs and 40k in about 60 mushroom samples (fruit bodies of basidiomycetes) belonging to 25 species collected in japan have been studied. the levels of 137cs varied very widely, ranging from less than 3 to 1520 bq kg-1 (dry wt), while those of 40k were relatively constant. concentrations of 137cs in common edible mushrooms of japan such as lentinus edodes, flammulina velutipes, pleurotus ostreatus and pholiota nameko were low (normally less than 50 bq kg-1, dry wt). conc ... | 1991 | 1925522 |
| ergosterol peroxides as phospholipase a(2) inhibitors from the fungus lactarius hatsudake. | four ergosterol derivatives (1-4) have been isolated for the first time from the fruiting bodies of a basidiomycete fungus, lactarius hatsudake, through activity-guided fractionation. their structures were determined, using spectroscopic analysis, as: (22e,24r)-ergosta-5,7,22-dien-3beta-ol (ergosterol, 1); 5alpha,8alpha-epidioxy-(22e,24r)-ergosta-6,22-dien-3beta-ol (ergosterol peroxide, 2); 5alpha,8alpha-epidioxy-(24s)-ergosta-6-en-3beta-ol (3); and (22e,24r)-ergosta-7,22-dien-3beta,5alpha,6beta ... | 2007 | 17292597 |

| analysis of genetic diversity of lactarius hatsudake in south china. | lactarius hatsudake is a type of ectomycorrhizal fungus that significantly influences the growth of pine trees. it is widely prevalent in asian countries and has a high economic value. artificial cultivation of this fungus has not been achieved as yet; therefore, excessive manual harvesting may cause serious damages to the site of its production. in this study, we analyzed 41 samples of l. hatsudake from south china using internal transcribed spacer (its) sequences. by comparing the differences ... | 2011 | 21815833 |
