Résumé
Objective To investigate the effect of lipid soluble fraction in the radix of Salvia miltiorrhiza (FSM) on conditioned place preference (CPP) in mice induced by morphine and preliminarily identify the fraction in the radix of S. miltiorrhiza. MethodsMorphine or NS was sc injected every other day to induce the obvious CPP in mice for 6 d. Before 30 min of sc injecting morphine, mice were ip administered different doses of lipid soluble fraction in the radix of S. miltiorrhiza. RP-HPLC method was used to identify the major component in the lipid soluble fraction in the radix of S. miltiorrhiza. ResultsThe staying time in morphine-paired white compartment was significantly prolonged. After treatment with lipid soluble fraction in the radix of S. miltiorrhiza (40 mg/kg, ip), the staying time in morphine-paired white compartment was significantly shortened (P
Résumé
Objective To study the effects of exogenous hormones,gibberellin(GA3)and indole-3-acetic acid(IAA),on growth and tanshinones accumulation in the radix of Salvia miltiorrhiza.MethodsThe herb characters and contents of tanshinones(cryptotanshinone,tanshinone Ⅰ,and tanshinone ⅡA)in the radix of S.miltiorrhiza with different hormone treatments were investigated and compared in the combination of trail pot and indoor analysis.Results It promoted aboveground biomass in the radix of S.miltiorrhiza increasing with single GA3.But it inhibited underground biomass increasing.The exogenous addition of low-level and high-level GA3 was benefit for tanshinones accumulation,whereas the middle-level GA3 wasn't.The aboveground and underground biomass in the radix of S.miltiorrhiza increased indistinctively with the increasing of IAA concentration and then decreased.And the IAA solutions also increased plant height and root length indistinctively.in a whole,it was benefit for tanshinones accumulation when applying low-level IAA(0.5 mg/L)singly.With the increasing of IAA concentration,the content of cryptotanshinone increased,but the contents of tanshinone Ⅰ and tanshinone ⅡA decreased.It promoted S.miltiorrhiza radix growth and three tanshinones contents increasing obviously with the combined application of two low-level hormones.Conclusion The applying of GA3 and IAA is benefit for the growth and three tanshinones accumulation in the radix of S.miltiorrhiza.
