Antioxidant activity of fruit bodies of Laetiporus sulphureus (Bull.: Fr.) Murr. (Polyporales) obtained by the natural plantation growing method in Pribaikal'e (Irkutsk region) has been studied. It was determined that the ethyl acetate fraction of L. sulphureus, which was chromatographically separated into seven compounds identified as quercetin, kaempferol, (+)-catechin, p-coumaric, gallic, caffeic, and chlorogenic acids was characterized with more expressed antioxidant activity. All compounds were extracted from this basidiomycete species for the first time. The quantitative amount of the substances isolated from L. sulphureus was determined by HPLC. It was found that antioxidant activity of preparations obtained from L. sulphureus is conditioned by phenolic compounds.
对在布里亚伊卡尔（伊尔库茨克地区）通过天然种植法获得的硫黄多孔菌（Laetiporus sulphureus (Bull.: Fr.) Murr.，多孔菌目）子实体的抗氧化活性进行了研究。结果确定，硫黄多孔菌的乙酸乙酯馏分经色谱分离得到七种化合物，分别鉴定为槲皮素、山奈酚、(+)-儿茶素、对香豆酸、没食子酸、咖啡酸和绿原酸，其具有更明显的抗氧化活性。所有这些化合物均首次从该担子菌物种中提取出来。通过高效液相色谱法测定了从硫黄多孔菌中分离出的物质的定量含量。结果发现，从硫黄多孔菌中获得的制剂的抗氧化活性受酚类化合物的影响。
