  1. HPTLC Bioautography Guided Isolation of α-Glucosidase Inhibiting Compounds from Justicia secunda Vahl (Acanthaceae)

    Extracts from the leaves of Justicia secunda Vahl (Acanthaceae) and fractions thereof were evaluated in terms of α-glucosidase inhibition performing HPTLC bioautography. Two active compounds were isolated via preparative HPTLC and semipreparative HPLC. Their identification and structure elucidation was achieved employing HPLC-ESI-MSn, HRESI-MS, and extensive NMR analyses, revealing the novel 2-caffeoyloxy-4-hydroxy-glutaric acid and the diastereomeric mixture of secundarellone B and C. This study presenting the α-glucosidase inhibiting potential of J. secunda supports its traditional medicinal use in diabetes mellitus treatment.

  2. Capillary Electrophoresis as Tool for Diastereomeric Separation in a Trichilia catigua Fraction

    Version of Record online: 2 DEC 2016 | DOI: 10.1002/pca.2653

    The tree Trichilia catigua shows several biological activities and has emerged as a potential source of new drugs. A methodology using CE-UV was developed and validated for analyzing ethyl-acetate fraction (EAF) of T. catigua. The method proved to be simple, sensitive, accurate, linear, precise and reproducible. When compared to the HPLC-PDA method previously developed, the CE method was more efficient, faster, less expensive and less polluting. This method could be employed for quality control of EAF of T. catigua.

  3. Separating and Identifying the Four Stereoisomers of Methyl Jasmonate by RP-HPLC and using Cyclodextrins in a Novel Way

    In this work, the separation and identification of the four stereoisomers of methyl jasmonate (MeJA) was carried out obtaining the following ordination: (−)epiMeJA, (−)MeJA, (+)MeJA and (+)epiMeJA. This could be a first step for a cell culture elicitation improvement.

  4. Reverse Phase Compatible TLC-Bioautography for Detection of Tyrosinase Inhibitors

    Paula García, I. Ayelen Ramallo and Ricardo L.E. Furlan

    Version of Record online: 2 DEC 2016 | DOI: 10.1002/pca.2655

    The first reverse phase-TLC bioautographic assay suitable for detection and identification of tyrosinase inhibitors in a complex matrix is described. The assay detected the reference inhibitor kojic acid at 0.03% (w/w) in a complex mixture. The analysis of the essential oil of Cinnamomum cassia (Nees & T.Nees) J. Presl showed inhibition provoked by cinnamaldehyde, a reported tyrosinase inhibitor.
