(Revista Brasileira de Ciências Farmacêuticas, 2004-09-01) [Artigo]
Do extrato etanólico dos capítulos de Paepalanthus microphyllus, isolou-se um derivado do ácido cafeico (1). Sua estrutura foi caracterizada por métodos espectroscópicos (RMN mono e bi-dimensionais) e por espetrometria de ...
Determination of Catechin Diastereomers from the Leaves of Byrsonima species Using Chiral HPLC-PAD-CD
(Chirality, 2010-08-01) [Artigo]
When catechins are found in plant extracts, they are almost always identified as catechin and/or epicatechin probably due to stereoselectivity of the enzymes involved in the biosynthesis of these substances. However, the ...
