Título :  INHIBITION OF ACETYLCHOLINESTERASE ACTIVITY BY HIDROALCOHOLIC EXTRACT AND THEIR FRACTIONS OF BOUVARDIA TERNIFOLIA (CAV.) SHCLTDL (RUBIACEAE).
Autor :  Ventura Zapata, Elsa
Fecha de publicación :  22-feb-2013
Resumen :  The Hydroalcoholic extract (BtHA) and its fractions of Bouvardia ternifolia were evaluated as inhibitor of the activity of the acetylcholinesterase enzyme utilizing the in vitro method (Ellman) BtHA inhibited the acetylcholinesterase enzyme competitively (lC50 = 0.6 g/ml); the ethyl acetate
Fraction (BtF-AcOEt) caused mixed.type inhibition (lC50 = 0.96 g/ml). A fraction insoluble on methanol (Bt-Faq-1) showed a mixed-type inhibition (lC50 = 0.96 g/ml). Finally, the metanol-soluble fraction (Bt-Faq-2), presented complex, mixed-type inhibition that corresponds to the C5 system (= 0.7 and =0.842). Rutin, quercetin, kaempferol and ursolic acid were detected by HPLC and the concetration of these compounds was different in each fraction.
