A review of natural products with antileishmanial activity
L.G. Rocha,Jackson Roberto Guedes da Silva Almeida,Rui Oliveira Macêdo,José Maria Barbosa-Filho +3 more
TL;DR: A review of the literature on plant extracts and chemically defined molecules of natural origin showing antileishmanial activity and some aspects of recent antileishesmanial-activity-directed research on natural products are discussed.
Journal ArticleDOI
Plants and chemical constituents with giardicidal activity
Flavia Maria Mendonça do Amaral,Maria Nilce de Sousa Ribeiro,José Maria Barbosa-Filho,Aramys Silva Reis,Flávia R.F. Nascimento,Rui Oliveira Macêdo +5 more
TL;DR: The objective of this study is to review the literature on plant extracts, fractions and chemical constituents whose giardicidal activity has been investigated in vitro and to discuss recent aspects of research on natural products of plant origin employed in the treatment of giardiasis.
Journal ArticleDOI
Thermal characterization of the quercetin and rutin flavonoids
Everaldo Moreira da Costa,José Maria Barbosa Filho,Ticiano Gomes do Nascimento,Rui Oliveira Macêdo +3 more
TL;DR: In this paper, a thermogravimetric (TG) and DSC coupled to a photovisual system was used to characterize rutin and quercetin.
Journal ArticleDOI
Anxiolytic-like activity and GC-MS analysis of (R)-(+)-limonene fragrance, a natural compound found in foods and plants.
Naiana G. P. B. Lima,Damião Pergentino de Sousa,Flávia Cristina Fernandes Pimenta,Mateus Feitosa Alves,Fábio Santos de Souza,Rui Oliveira Macêdo,Ricardo Barros Cardoso,Liana Clébia Soares Lima de Morais,Margareth de Fátima Formiga Melo Diniz,Reinaldo Nóbrega de Almeida +9 more
TL;DR: The data indicate that (+)-limonene could be used in aromatherapy as an antianxiety agent and suggest possible connections between the volatility of (+)- Limonene and its anxiolytic-like effect on the parameters evaluated in the elevated plus maze test.
Journal ArticleDOI
Simultaneous determination of ranitidine and metronidazole in human plasma using high performance liquid chromatography with diode array detection.
TL;DR: With this one-step sample preparation method, both ranitidine and metronidazole could be quantified simultaneously in human plasma with good precision (R.S.D.<15%) and accuracy (bias values below 15%).
