Abstract:
This study was aimed to investigate the diuretic effect ofMori Cortex and to identify effective fractions inM. Cortex. Metabolic cages were used to firstly observe the diuretic effect ofM. Cortex aqueous extracts on rats. Medications were continuously given for 5 days to screen for the best dosage of diuretic effect. Picric acid assays were used to detect creatinine levels in serum and urine after 5-day medication. Then, the diuretic effect of each chemical split fraction inM. Cortex was studied in order to indentify the effective parts. The results showed that after administration ofM. Cortex aqueous extracts for 3 to 5 days, compared with the control group, there was a significant diuretic effect on rats (P<0.05 orP<0.01). And the medium-dose ofM. Cortex aqueous extracts showed the best effect (P<0.01). However,M. Cortex aqueous extracts had no significant effect on creatinine levels in serum and urine. Assays of diuretic effect of chemical split fractions ofM.Cortex indicated that compared with the control group, 30% ethanol fraction and fatty oil fraction had the best diuretic effect (P<0.01). It was concluded thatM.Cortex aqueous extracts had a significant diuretic effect. And the chemical fractions contributed mostly to this effect were mainly existed in the 30% ethanol fraction and fatty oil fraction.
