Francisco Artur Forte Oliveira,Mariana Helena Chaves,Fernanda R.C. Almeida,Roberto C.P. Lima,Regilane M. Silva,Juliana L. Maia,G. A. C. Brito,Flávia A. Santos,Vietla Satyanarayana Rao +8 more
TL;DR: The findings indicate the hepatoprotective potential of α- and β-amyrin against toxic liver injury and suggest that the diminution in oxidative stress and toxic metabolite formation as likely mechanisms involved in its hepatoprotsection.
Journal ArticleDOI
Antihyperglycemic and hypolipidemic effects of α, β-amyrin, a triterpenoid mixture from Protium heptaphyllum in mice.
Flávia A. Santos,Julyanne Torres Frota,Bruno Rodrigues Arruda,Tiago Sousa de Melo,Armenio André de Carvalho Almeida da Silva,Gerly Anne de Castro Brito,Mariana Helena Chaves,Vietla Satyanarayana Rao +7 more
TL;DR: These findings reflect the potential antihyperglycemic and hypolipidemic effects of α, β-amyrin mixture and suggest that it could be a lead compound for drug development effective in diabetes and atherosclerosis.
Journal ArticleDOI
Anti-inflammatory effect of alpha, beta-Amyrin, a pentacyclic triterpene from Protium heptaphyllum in rat model of acute periodontitis.
S. A. Holanda Pinto,L. M. S. Pinto,Geanne M. A. Cunha,Mariana Helena Chaves,Flávia A. Santos,Vietla Satyanarayana Rao +5 more
TL;DR: Evidence is provided to show that α, β-Amyrin retards acute inflammation in rat model of periodontitis and warrant further study on its efficacy to prevent chronicperiodontitis-associated bone loss.
Journal ArticleDOI
Evaluation of a methylation procedure to determine cyclopropenoids fatty acids from Sterculia striata St. Hil. Et Nauds seed oil.
TL;DR: In this paper, cyclopropenoids fatty acids from Sterculia striata seed oil were characterized by gas chromatography/mass spectrometry (GC/MS) and quantified by GC-FID after derivation to fatty acid methyl esters using a cold base-catalyzed procedure.
