Extraction of Bioactive Compounds from Prestonia mollis Leaves and Their Impregnation into Polylactic Acid Using High-Pressure Technologies: Potential for Biomedical Application [PDF]
Antioxidants, 2023 Enhanced solvent extraction (ESE) and pressurized liquid extraction (PLE) have been used for the first time to obtain antioxidant compounds from Prestonia mollis leaves. The effects of pressure (100–250 bar), temperature (55–75 °C) and the composition of

Enabling evolutionary studies at multiple scales in Apocynaceae through Hyb-Seq. [PDF]
Appl Plant Sci, 2020 Premise Apocynaceae is the 10th largest flowering plant family and a focus for study of plant–insect interactions, especially as mediated by secondary metabolites. However, it has few genomic resources relative to its size. Target capture sequencing is a powerful approach for genome reduction that facilitates studies requiring data from the nuclear ...

Evolution of pyrrolizidine alkaloid biosynthesis in Apocynaceae: revisiting the defence de-escalation hypothesis. [PDF]
New Phytol, 2018 Summary Plants produce specialized metabolites for their defence. However, specialist herbivores adapt to these compounds and use them for their own benefit. Plants attacked predominantly by specialists may be under selection to reduce or eliminate production of co‐opted chemicals: the defence de‐escalation hypothesis.

Environmental heterogeneity influences liana community differentiation across a Neotropical rainforest landscape. [PDF]
Ecol EvolBy analyzing liana community variation among land units (LUs) that differ in geomorphology and soil properties along a 640‐ha tropical rainforest landscape in a neotropical reserve, we found strong evidence supporting our hypothesis that environmental heterogeneity, as represented by discrete LUs, promotes differentiation in liana composition across ...

HPLC-MS detection of pyrrolizidine alkaloids and their N-oxides in herbarium specimens dating back to the 1850s. [PDF]
Appl Plant Sci, 2018 Premise of the Study Understanding the phylogenetic distribution of defensive plant secondary metabolites is essential to the macroevolutionary study of chemically mediated plant–animal interactions. The chemical ecology of pyrrolizidine alkaloids (PAs) has been extensively studied in a number of plant–herbivore systems, including Apocynaceae (the ...
