TL;DR: The methodology was successfully applied to determine the fatty acid composition of several edible oils, with equivalent results to those given by the AOAC Official method by gas chromatography.

TL;DR: Bioassay-guided fractionation of the bark extract of Annona foetida afforded a new antileishmanial pyrimidine-beta-carboline alkaloid, N-hydroxyannomontine, which is particularly important for Annona genus chemotaxonomy.

TL;DR: In this article, the authors used both elemental and spectroscopic properties of humic acids (HA) isolated from bottom sediment samples of a stream in a Brazilian subtropical microbasin by elemental analysis, and infrared, ultraviolet and visible (UV-Vis) and solid-state 13C nuclear magnetic resonance (CP-MAS 13C NMR) spectroscopies, thermogravimetry (TG), and scanning electron microscopy (SEM).

TL;DR: In this article, the authors present a comprehensive review of the scientific value of disseminating raw nuclear magnetic resonance (NMR) data, independently of, and in parallel with, classical publishing outlets.

TL;DR: Phytochemical investigation of the branches of Annona foetida Mart led to isolation from the CH2Cl2 extract of four alkaloids: Atherospermidine, described for the first time in this species, liriodenine, O-methylmoschatoline, and annomontine, whose chemical structures were established on the basis of spectroscopic data from IR, MS, NMR, and comparison with the literature.
