ABSTRACT
Objective To investigate the different compatibility of tripterygium wilfordii on its attenuation and synergistic effects through applying Leigongteng decoction and its demolition decoctions on nephrosis rats,and to select the optimizing decoction to treat nephrotic syndrome.Methods 110 Wister rats were divided into 11 groups randomly,which were 9 groups of nephrosis model groups (including Leigongteng group,Leihe group,Leigui group,Leiqi group,Leigongteng ecoction group,Leijin group,Leigan group,prednisone group and nephrosis model group) and 2 blank groups (normal control group and normal Leigongteng group),10 rats in each group.The normal control group and normal Leigongteng group was intravenous injected with 0.65 ml sodium chloride in caudal vein; 9 groups of nephrosis model groups were injected with 0.65 ml adriamycin.The prednisone group was selected for positive control,24h urine protein,total protein,albumin,urea nitrogen,and creatinine were tested with automatic biochemistric meter.Results ALB (27.58±2.62)g/L,Leigan group Compared with(92.60± 18.12) mg in Leigongteng group,the urine protein in Leigongteng diction group(48.60± 11.75) mg,Leiqi group (53.20± 13.21) mg,and Leigan group (56.40 ±16.52) mg were reduced.Compared with the Leigongteng group TPR(58.98±4.84) g/L,ALB (20.98 ± 3.49) g/L,the Leigongteng decoction group [TPR (68.47 ± 5.25) g/L,ALB (28.97± 3.01) g/L],TPR and ALB in Lei-Qi group TPR(68.21 ±4.19) g/L,TPR(67.51 ± 5.42) g/L,ALB (26.56± 1.89) g/L were all elevated.Compared with Leigongteng group chol (1.48 ± 0.65) mmol/L TG (1.70 ± 1.58) mmol/L,chol and TG in the Leigongteng decoction group chol(0.78±0.13)mmol/L,TG(0.56±0.14)mmol/L,Lei-Qi group chol (0.70±0.13) mmol/L,TG (0.65±0.12) mmol/L,and Leigan group chol (0.97±0.33) mmol/L,TG(0.66±0.18) mmol/L were lowered; compared with Leigongteng group,UN (14.20 ± 2.12) mmol/L,Cr (78.10 ± 6.14) μmol/L,UN and Cr in the Leigongteng decoction group UN(7.59±0.78) mmol/L,Cr(39.60±8.33) μmol/L,Leigan group UN (9.48 ± 0.82) mmol/L,Cr(38.30±7.89)μmol/L,and Leijin group UN(9.71±1.33) mmol/L,Cr(41.40±6.45) μmol/L,Leigui group UN(8.30±1.12) mmol/L,Cr(36.90±6.15) μmol/L were all reduced with significant differences (all P＜0.05).The changes of Kidney morphology and ultrastructure pathology in Leigongteng different combination groups were lighter than the control groups.Conclusion Leigongteng decoction group,Leiqi group,Leigan group had synergistic actions,while Leigongteng decoction group,Leigan group,Leijin group,and Leigui group had kidney toxicity-reducing actions.
ABSTRACT
Objective To investigate the chemical constituents of Wedelia trilobata.Methods The chemical constituents were separated by chromatography and their structures were determined by physico-chemical constants and spectral analyses.Results Eleven compounds were isolated and identified as grandiflorenic acid(1),1?-acetoxy-6?,9?-dihydroxy-4,10?-dimethyl-5?H,7?H,8?H-endesm-3-en-8,12-olide(2),1?-acetoxy-4?-hydroxy-6?-isobutyryloxy-9?-isovaleryloxyprostatolide(3),16?-hydroxy-ent-kauran-19-oic acid(4),(3R,4R,6R)-3,4-dihydroxy-1-menthene(5),trilobolide-6-O-isobutyrate(6),1?-acetoxy-4?,9?-dihydroxy-6?-isobutyroxyprostatolide(7),16?,17-dihydroxy-ent-kauran-19-oic acid(8),daucosterol(9),protocatechualdehyde(10),and caffeic acid(11).Conclusion All the compounds are isolated from W.trilobata for the first time except compounds 6 and 7.Compounds 2 and 3 are new sesquiterpene lactones,named as trilobolide A and 1?-acetoxy-4?-hydroxy-6?-isobutyryloxy-9?-isovaleryloxyprostatolide,respectively.
