RESUMO
AIM To study the chemical constituents from Gentianella acuta (Michx.) Hulten.METHODS The 30％ and 90％ ethanol fractions of 70％ ethanol extract from G.acuta were isolated and purified by silica,ODS and preparative HPLC column,then the structures of obtained compounds were identified by spectral data.RESULTS Nine compounds were isolated and identified as sinenoside Ⅰ (1),(+)-lariciresinol-4,4'-0-bis-β-D-glucopyranoside (2),(+)-8-hydroxylariciresinol-4'-O-β-D-glucopyranoside (3),(+)-lariciresinol-4-O-3-D-glucopyranoside (4),(7S,8R)-erythro-7,9,9'-trihydroxy-3,3'-dimethoxy-8-O-4'-neolignan-4-O-β-D-glucopyranoside (5),(7S,8R)-erythro-4,9,9'-trihydroxy-3,3'-dimethoxy-8-O-4'-neolignan-7-O-β-D-glucopyranoside (6),(7S,8R)-erythro-4,7,9-trihydroxy-3,3'-dimethoxy-8-O-4'-neolignan-9'-O-β-D-glucopyranoside (7),balanophonin (8),urolignoside (9).CONCLUSION Compounds 2-9 are isolated from genus Gentianella for the first time.
RESUMO
Objective To explore clinical value of serum total bile acid(TBA) and cholinesterase(CHE) in infantile hepatopathy.Methods Sixty infants diagnosed respectively with breast milk jaundice,cytomegalovirus hepatitis and congenital bile duct teratism were included.Twenty healthy infants were as control.The infants of cytomegalovirus hepatitis were self-compared in acute stage and convalescence stage.Serum TBA and CHE in every group were measured and compared.Results Serum TBA in control group,breast milk jaundice group,cytomegalovirus hepatitis group and congenital bile duct teratism group were(6.47?3.25),(8.71?1.79),(45.86?40.85),(119.50?31.73) ?mol/L,respectively;and CHE were(11295.50?1731.91),(10762.89?1237.30),(9771.32?860.27),(7967.304?31.58) U/L,respectively.Compared with other groups,the level of serum TBA and CHE in cytomegalovirus hepatitis group and the congenital bile duct teratism group were significantly different(all P
