“…The Euphorbiaceae family comprises 219 genera and 6300 species, which are distributed in tropical and subtropical regions, and many of them are endemic to Brazil [ 1 ]. This plant family has a very diverse secondary metabolism, and their metabolites are characterized by their medicinal properties [ 2 , 3 ]. The species of the Euphorbiaceae family have suffered throughout history, with several reorganizations within the subfamilies, genera, and even segregations of other families.…”

“…It is a tree that can reach 40 m, has no latex, and is restricted and exclusive to the Brazilian Amazon. This species is found mainly in flooded areas and has never been studied chemically [ 3 ]. Metabolite profiling using high-resolution mass spectrometry (HRMS) grants access to large volumes of high-quality spectral data from a minimal amount of samples, and appropriate data analysis workflows allow the efficient mining of such data [ 16 ].…”

“…An approach to dereplicating the extracts of leaves, roots, bark, and stem bark of A. uleanus was adopted in order to discover as much as possible the classes of natural products present in that species using tools such as MZmine 2, MS-DIAL, MSFINDER, and GNPS. The aim of this work was to describe, as extensively as possible, the array of natural products present in A. uleanus and to establish chemophenetic correlations with other species in Euphorbiaceae [ 3 , 17 ].…”

Anomalocalyx uleanus (Pax & K. Hoffm.) Ducke (Euphorbiaceae) is a singular species in the genus and is restricted and exclusive to the Brazilian Amazon. A phytochemical study of A. uleanus leaves was performed, yielding the isolation of five major compounds: catechin/epicatechin, afzelin, quercetin 3-O-α-L-rhamnopyranoside, and astilbin. The phytochemical compositions of the methanolic extracts of leaves, roots, bark, and stem bark were determined using a dereplication approach. Forty-six compounds were annotated from the liquid chromatography-mass spectrometry (LC-MS/MS) data, while four lipids were identified using gas chromatography-mass spectrometry (GC-MS). In total, fifty compounds were detected, and they belonged to the primary metabolism and several classes of natural products such as flavonoids, flavonoids O-glycosides, flavonoids C-glycosides, biflavonoids, procyanidin, triterpene, triterpenes esterified with phenylpropanoids, phenylpropanoid derivatives, flavonolignans, coumarins, quinic acid derivatives, and benzoic acid derivatives. This is the first report on the phytochemical data of the genus Anomalocalyx, and the results of this study will contribute to the chemosystematic knowledge of the Euphorbiaceae family and justify the need for investigation of the pharmacological potential of the species A. uleanus.

Chemical investigation of extracts from the stems and leaves of Alchorneopsis floribunda Müll. Arg., collected in the Amazon region, was performed. The main isolated compounds were triterpenes (α-amyrin, β-amyrin, lupeol, betulin, betulinic acid, uvaol, erythrodiol and oleanolic acid) and phenolic acid derivatives from 4-hydroxybenzoic acid (gallic and protocatechuic acids and isocorilagin). In the germination assays, high inhibitory allelopathic effects of the extracts and isocorilagin were observed and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity of isocorilagin was higher than those of the standards used (Trolox and butylated hydroxyanisole). This is the first chemical study of the genus Alchorneopsis (Euphorbiaceae).
