In order to explain the antidepressive effect of Xiaoyaosan, all of the recent reports were sought out on the current situation of the antidepressive monomer compositions of Xi- aoyaosan and their mechanism. By exploring the relationship between the effects and the active ingredients, the mechanism and the active ingredients, the antidepressive active ingredients such as quercetin, isorhamnetin, isoliquiritigenin, saikosaponinA, saikosaponinD, glycyrrhiz- kaempferol, liquiritin, isoliquiritin, liquiritigenin, inate, paeoniflorin, albiflorin, ferulic acid, curcumin and their mechanism of antidepressive such as regulating the monoamine neurotransmitter systems, regulating the neuroendocrine system, affecting the neural plasticity and neu- affecting the cytokines level, anti-oxidative stress were rotrophic, affecting the cellular and molecular mechanisms , summarized. By the overview in the level of monomer rather than formulae, we uncovered the antidepressive mech- anism of Xiaoyaosan and further confirmed that Xiaoyaosan, as a classic antidepressive Chinese prescription, had many characteristics, such as multi-level , multi-channel, multi-target and so on .展开更多
通过比较不同基质中药用石斛生长量和有效成份质量分数,探究经过无害化处理的松材线虫病疫木在铁皮石斛(Dendrobium officinale Kimura et Migo)人工栽培中作为配方基质的使用效果。结果表明:在铁皮石斛人工种植中使用经过无害化处理后...通过比较不同基质中药用石斛生长量和有效成份质量分数,探究经过无害化处理的松材线虫病疫木在铁皮石斛(Dendrobium officinale Kimura et Migo)人工栽培中作为配方基质的使用效果。结果表明:在铁皮石斛人工种植中使用经过无害化处理后的松材线虫病疫木作为栽培基质切实可行。不同栽培方式适用的松材线虫病疫木替代基质的比例不同。以盆栽方式种植铁皮石斛时,1号基质(V(粒径9~12 mm疫木颗粒)∶V(新鲜树皮)∶V(饼肥)=1∶1∶1)充分发酵后可以在实际生产中替代常规栽培基质使用;以盘栽方式种植铁皮石斛时,3号基质(V(疫木锯末)∶V(新鲜树皮)∶V(饼肥)=1∶1∶1)充分发酵后可以在实际生产中替代常规栽培基质使用。展开更多
