Abstract:
To search for the active diuretic fractions of Clematidis Armandii Caulis( CAC) and determine its main active chemical components by using liquid chromatography-mass spectrometry( LC-MS) and diuretic activity evaluation. CAC 75% ethanol extracts and extracts from different polar solvents were orally administered to saline-loaded rats at different doses. 6 h urinary volume,p H and contents of electrolyte Na+,K+and Cl-were measured. The chemical components of the active fractions were separated and identified by ultra performance liquid chromatography-electrospray ionization-quadrupole time of flight-mass spectrometry( UPLC-ESI-Q-TOF-MS/MS) method. As compared with the control group,the urine volume was increased by 44%( P< 0. 01) and 34%( P < 0. 05) in CAC75% ethanol extract 57. 74 and 28. 8 mg·kg-1 groups respectively; the Na+excretion was increased by 52%( P< 0. 01) and 45%( P<0. 05),respectively; while the Cl-excretion was increased by 101%( P<0. 01) and 85%( P<0. 05),respectively. The urine volume,Na+excretion and Cl-excretion were increased by 50%( P< 0. 01),58%( P< 0. 05),and 65%( P< 0. 05) respectively in petroleum ether extract 70. 98 mg·kg-1 group as compared with the control group. While for the n-butanol extract 194. 18 mg·kg-1 group,the urine volume,Na+and Cl-excretion were increased by 42%( P<0. 01),41%( P<0. 05) and 97%( P<0. 01),respectively. The diuretic activity of other fractions was not obvious. There was no statistical difference in K+excretion in all groups. The results of LC-MS analysis showed that six compounds,including two sterols,one chromogen and three fatty acids,were identified from petroleum ether extract.Fourteen compounds,including six triterpenoid saponins,six lignin glycosides,one sterol glycoside and one phenolic glycoside,were identified from the n-butanol extract. All the results suggested that the ethanol extract of CAC had remarkable diuretic activity and its main effective components included sterol,triterpenoid saponin and lignin glycosides.
