摘　　要：从天然植物虎杖中提取有效成分,并与可生物降解材料聚丁二酸丁二醇酯(PBS)复合,探究了虎杖提取物对PBS的影响,同时将复合材料粉碎并混入土壤中,通过检测蚯蚓体内的蛋白质含量、过氧化氢酶及纤维素酶活性对其对土壤污染程度进行了环境评价,结果表明:虎杖提取物/PBS复合材料的亲水性大大增加,虎杖提取物对PBS结晶也有一定促进作用.虎杖提取物/PBS复合材料降解伴随PBS的降解和提取物的降解协同产生,提取物作为小分子物质首先被微生物侵蚀,增大了复合材料与微生物及水分子的接触面积.虎杖提取物及其复合材料能够对蚯蚓中的蛋白质的合成、过氧化氢酶(CAT)、纤维素酶的活性起到促进作用,对环境友好.Effective ingredients extracted from natural plant Polygonum cuspidatum,and a biodegradable material poly butyl diacid butyl glycol ester(PBS)composite,explores the influence on PBS,Polygonum cuspidatum extract will composite material crushing and mixed in the soil at the same time,by detecting the earthworm body protein content,catalase and cellulose enzyme activity of soil pollution on the environment evaluation,The results showed that the hydrophilicity of Polygonum cuspidatum extract/PBS composite material increased greatly,and the extract also promoted the crystallization of PBS to a certain extent.The degradation of Polygonum cuspidatum extracts/PBS composites was accompanied by the synergistic degradation of PBS and the degradation of extracts.The extracts,as small molecules,were first eroded by microorganisms,which increased the contact area between the composites and microorganisms and water molecules.The extracts of Polygonum cuspidatum and its composite material can promote the synthesis of protein,catalase(CAT)and cellulase activity in earthworm,which is friendly to the environment.
