Abstract:
Objective:To investigate the proliferation of rat glomerular mesangial cells (GMC) influenced by different ethanol extracts of Tripterygium wilfordii HooK F.(TWHF).Methods:An HPLC method was used to establish the fingerprints of 5 different ethanol extracts of TWHF,and GMC was chosen to study the effects of different ethanol extracts of TWHF on cell proliferation.After statistical analysis,the spectrum-activity relationship was analyzed by using partial least squares regression(PLSR).Results:The HPLC fingerprints of the 5 different ethanol extracts of TWHF were established,and 32 characteristic peaks were characterized by the HPLC fingerprints.60%,70% and 95% ethanol extracts and glycosides tablets showed dose-effect relationship,and with the increase of dose,the more significant inhibition of cell proliferation was exhibited.The absorbance values of the 60% ethanol extracts at medium and high doses were lower than those of the other extracts at the same dose.The proliferation inhibition rate of GMC was used as the potency index and analyzed by PLSR,and 20 peaks were potency peaks at high dose(40 μg·L-1),17 ones were potency peaks at medium dose(20 μg·L-1) and 15 ones were potency peaks at low dose(10 μg·L-1).Conclusion:Part of the potency peaks has regular dose-effect relationship with the changes of dose.
