“…Seven species of Campomanesia (approximately 15% of the total species) were sampled, including representatives from the three morphological complexes of Landrum (1986) and the two monophyletic groups determined by Oliveira et al (2021). Samples of seeds of Psidium guajava were used as an outgroup.…”

“…Based on morphological characters, Landrum (1986) organized 18 species of Campomanesia, distributed into three informal groups: "Campomanesia grandi ora complex", "Campomanesia guazumifolia complex" and "Campomanesia xanthocarpa complex"; several of its species were poorly known or had unde ned a nities. A recent phylogenetic analysis conducted by Oliveira et al (2021), based on the internal transcribed spacer of ribosomal DNA (ITS region), revealed that the "C. xanthocarpa complex" is not monophyletic. Its species emerge in two distinct lineages, designated as "C. xanthocarpa Group" and "C. eugenioides Group", the former also including species of the "C. guaviroba complex".…”

“…Its species emerge in two distinct lineages, designated as "C. xanthocarpa Group" and "C. eugenioides Group", the former also including species of the "C. guaviroba complex". Further investigation aiming to clarify the systematics of the genus, including sequences of additional DNA regions, as well as data from morphology, anatomy, and chemistry, is expected to shed light on the phylogenetic relationships among Campomanesia species (Oliveira et al, 2021).…”

The present work aimed to determine the fatty acid (FA) composition of seed oils of Campomanesia (Myrtaceae), a genus with approximately 45 species restricted to South America. The work aimed also to evaluate the systematic bearing of FA profiles, as well as their degree of congruence with phylogeny. Seeds of Psidium guajava and seven species of Campomanesia were collected from at least two individuals from distinct populations. The seed oils were extracted and the methyl esters of the FA were analyzed by gas chromatography and mass spectrometry. Nucleotide sequences from GenBank of the same species, regarding the internal transcribed spacer of ribosomal DNA (ITS), were used for phylogenetic analysis. Seed FA profiles were distinct, comparing Campomanesia and Psidium guajava; linoleic acid predominates in the seed oil of the latter species, while saturated and mono-unsaturated FA predominate in the seed oil of Campomanesia. A high similarity of FA profiles was noted, when comparing specimens of the same species. With few exceptions, cluster and principal component analyses based on FA profiles were congruent with phylogeny based on ITS sequences. Distribution of seed FA supports the non-monophyletic status of the “C. xanthocarpa complex”. Reconstruction of ancestral character states revealed distinct evolutionary trajectories of FA profiles toward differentiation of Campomanesia clades, all of them leading to decreased proportions of unsaturated FA.

The species Campomanesia guazumifolia (Cambess.) O. Berg is a fruit tree native to the southern region of South America, occurring sparsely in secondary forests. It presents different ethnobotanical uses, mainly by indigenous populations. Its fruit is used for food purposes, in nature, or handcrafted products. Its cultivation has been investigated, with its seedlings being used in reforestation due to its ecological importance. Studies on the leaves of C. guazumifolia highlight the presence of phenolic compounds. The essential oil composition of the leaves has also been analyzed. Biological activities have already been investigated: insecticide, antioxidant and antimicrobial. C. guazumifolia is little explored, despite the great potential for the elaboration of products due to its ethnobotanic indication and capacity to produce edible fruits. Palavras-chave: Patents. Fruits. Chemical composition. Campomanesia guazumifolia (Cambess.) O. Berg: Etnobotanica, cultivo e potencialidades RESUMOA espécie Campomanesia guazumifolia (Cambess.) O. Berg é uma árvore frutífera nativa da região sul da América do Sul, ocorrendo de forma pouco densa em matas secundárias. Apresenta diferentes usos etnobotanicos, principalmente por populações indígenas. Seu fruto é utilizado para fins alimentícios, in natura ou em produtos artesanais. Seu cultivo vem sendo investigado, com suas mudas sendo utilizada em reflorestamento devido a sua importância ecológica. Há estudos a respeito das folhas de C. guazumifolia que destacam a presença de compostos fenólicos. A composição do óleo essencial das folhas também já foi analisada. Já foram investigadas as atividades biológicas: inseticida, antioxidante e antimicrobiana. A C. guazumifolia é pouco explorada, apesar do grande potencial para elaboração de produtos devido a sua indicação etnobotânica e sua capacidade de produzir frutos comestíveis.
