Abstract : the anti - inflammatory effect of n - butanol extract of xanthocerassorbifolia bunge ( bex ) was studied in this paper. the ear edema resulted from dimethyl benzene, paw edema induced by carrageenin, the increase of vascular permeability caused by acetic acid, the chemotaxis of wbc induced by cmc and the weight of cotton granuloma in mice and hind paw edema induced by fresh egg white in rats were inhibited significantly by ig bex daily for 7 days, respectively. the carrageenin - induced paw edema was also inhibited markedly in adrenal - ectomiced mice. no changes in weight of adrenal and the concentration of vitamin c were observed, indicating that the anti - inflammatory effect of bex was not related to pituitary - adrenal system

水處理劑.氨基三甲叉膦酸Amino trimethylene phosphonic acid atmp
Atmpa氨基三甲叉膦酸A facile method for the preparation of 10 - arylmethylene anthrone is reported. when anthrone react with aryl aldehyde in the presence of pyridine by using xylene as the solvent, besides 10 - arylmethylene anthrone derivatives we found other oxygenated anthrone which have not been reported. physical methods shows that the oxygenated anthrone is anthraquinone, and the anthraquinone cannot be removed from the condensed products by recrystallization with solvents. an effective method of getting ride of anthraquinone is sublimation by heating
以蒽酮和芳香醛為原料，二甲苯為溶劑，吡啶催化法制取10 -芳香基甲叉基蒽酮.發現其生成物中除含有目標化合物10 -芳香基甲叉基蒽酮外，還含有部分文獻中沒有報道的蒽酮氧化物，經物理方法確定其為蒽醌.該化合物不能用溶劑重結晶的方法將其從縮合產物中除去，有效的分離方法是升華The percentage of polymorphic sites, degree of genetic polymorphism and genetic distance were compared and the phylogenetic tree was constructed by neighbor - joining method. the partial mitochondrial 16s rrna gene was amplified by polymerase chain reaction ( pcr ) and the pcr products were directly sequenced after purified. these sequences, together with the homologous sequences of another trichiuridae species lepidopus caudatus obtained from genbank were used to analyze nucleotide difference and to establish a upgma phylogenetic tree by means of biological informatics
