ABSTRACT
Objective: To compare the content of total saponins and total polysaccharides between formula granule and traditional decoction of Sijunzi decoction.Methods: UV spectrophotometry was used to determine the content of total saponins and total polysaccharides in formula granule and traditional decoction of Sijunzi decoction respectively at the wavelength of 540 nm and 488 nm.Results: The absorbance of ginsenoside Re had a good linear correlation with the concentration within the range of 10.909-65.454 μg · ml-1 (r=0.999 7), and the average recovery was 98.49%(RSD=0.85%, n=6);the absorbance of D-anhydrous glucose had a good linear correlation with the concentration within the range of 2.160-12.960 μg · ml-1 (r=0.999 7), and the average recovery was 99.46%(RSD=0.73%, n=6).The contents of total saponins from 3 batches of formula granule were slightly higher than those from traditional decoction,and that of total polysaccharides in formula granule was slightly lower than that in traditional decoction,and there was no significant difference between the two groups (P>0.05)Conclusion: The difference of material basis between formula granule and traditional decoction of Sijunzi decoction is small, and formula granule is more feasible for clinical application.
ABSTRACT
Objective:To investigate the inhibitory effects of Sedum Sarmentosum total flavonoids ( SSTF) on hepatic fibrosis in-duced by CCl4 ,and examine the effects on the expression of TGF-β1 and Smad7. Methods:Sixty male SD rats were randomly divided into the normal control group, the model group, 100, 200 and 400 mg·kg-1 SSTF groups and colchicine positive control group. The experimental model of hepatic fibrosis in rats was established by the injection of CCL4 . The liver histopathology was examined by Mas-son stain, and the protein expression and mRNA of TGF-β 1 and Smad7 were assessed by RT-PCR and Western blotting. Results:Compared with the model group, every SSTF group could significantly reduce the degree of liver fibrosis induced by CCL4(P<0. 05). The middle and high dose SSTF gouprs could significantly reduce the protein expression and mRNA of TGF-β1 (P<0. 05), and sig-nificantly increase the protein expression and mRNA of Smad 7 (P<0. 05). Conclusion:SSTF exhibits anti-hepatic fibrosis effects in rats through down-regulating the expression of TGF-β1 and up-regulating the expression of Smad7 in fibrotic liver tissue.
