title: [Influence of extraction on fluorescence of the subrenite in the peat].
abstract: Comparative study on the subrenite in the peat and extracted remain has been made. The study reveals that extraction has considerable influence on the fluorescence of the subrenite. Before extracted, the subrenite in the peat gives out violently fresh yellowish green to green fluorescent light ,and the lambda(max), ranges from 470 to 520nm and the Q650/500 from 0.10 to 0.65, but after extracted, the subrenite in the extrated remain gives out weakly dark yellow to orange-yellow fluorescent light and the lambda(max) ranges from 605 to 660nm and the Q650/500 from 1.85 to 4.09. The extraction has made the fluorescent intensity of the subrenite weak.
