Abstract:
OBJECTIVE To establish the fingerprint of total saponins from Mussaenda pubescens， and to study the spectrum- effect relationship of its hepatoprotective activity. METHODS Ten batches of total saponins from M. pubescens from different origins were prepared using 75% ethanol as solvent. High-performance liquid chromatography （HPLC） and the Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprints （2012 edition） were used to draw the fingerprints of 10 batches of total saponins from M. pubescens. The similarity evaluation and identification of common peaks were conducted. The same HPLC method was adopted to determine the contents of five triterpenoid saponins （mussaendoside H， mussaendoside U， mussaglaoside C， mussaendoside G and mussaendoside O）. The hepatoprotective effect of total saponins from M. pubescens was investigated by establishing carbon tetrachloride-induced acute liver injury model mice， and the spectrum-effect relationship was studied by using grey correlation analysis. RESULTS There were 11 common peaks in 10 batches of total saponins from M. pubescens， 5 of which were identified， i.e. mussaendoside H （peak 3）， mussaendoside U （peak 7）， mussaglaoside C （peak 8）， mussaendoside G （peak 9） and mussaendoside O （peak 11）； the similarities of 10 batches of samples ranged 0.940- 0.991. Average contents of mussaendoside H， mussaendoside U， mussaglaoside C， mussaendoside G， mussaendoside O were 0.01- 0.05， 0.10-0.21， 0.10-0.18， 0.03-0.08， 0.20-0.40 mg/g， respectively. Ten batches of total saponins from M. pubescens could generally reduce the contents of alanine aminotransferase （ALT） and aspartate aminotransferase （AST） in serum， and tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6） and IL-1β in liver tissue of model mice （P＜0.05 or P＜0.01）. The E-mail：13878195336@139.com correlation between the common peak areas and the contents of ALT， AST， TNF-α， IL-6 and IL-1β were 0.602-0.757， 0.585-0.833， 0.593-0.795， 0.618-0.820， 0.607-0.804， respectively； the peaks with high correlation were peaks 11， 9 and 8 in order. CONCLUSIONS Ten batches of total saponins from M. pubescens have similar components， and the average contents of mussaendoside H， mussaendoside U， mussaglaoside C， mussaendoside G and mussaendoside O are different. The batches of samples have a certain degree of hepatoprotective effect； mussaendoside O， mussaendoside G and mussaglaoside C may be its main active components.
