ABSTRACT
Objective:To study the pharmacokinetic process ofbrucine from normal and ultra-micro powder ofsemen strychni in rat serum.Methods:HPLC techniques were used.All pharmacokinetics parameters were calculated with a 3P87 program.Results:The pharmacokinetics results indicated that the normal powder and the ultra-micro powder ofsemen strychni belonged to two compartment open model.The absorb ofbrucine was just several ten minutes, and there was no obvious difference ofTmax between normal powder and ultra-micro powder.This showed that:Brucine was some material that was easily absorbed.But we can find that Cmax increased from(51.13?0.48)?g/L to(69.26?1.40)?g/L after ultra-micro powder preparation which was quite obvious.K,Ka,B and ? had a obvious increase(P
ABSTRACT
Objective:Dissolution test was applied to study the dissolution rates of strychnine from the normal and ultramicro powder of semen strychi. Methods:HPLC techniques was used to detect the dissolution amount and the dissolution velocity of strychnine from the normal and ultra-micro powder of semen strychi. Results:The dissolution velocity of strychnine from the ultra-micro powder was higher than that from the normal powder,but there was no difference in the dissolution amount 4 hours later. Conclusion:The dissolution velocity of strychnine from the ultra-micro powder increased greatly and there was no loss of the principal active.
