“…In the case of rosewood, current efforts are being made globally to bring sustainability to the rosewood essential oil industry through in-situ and ex-situ germplasm collections (Amusant et al 2016). Most studies on the species have been about the activity of its essential oil (Sarrazin et al 2016;Amusant et al 2016;Maia and Mourão 2016). Information about the genetic characterization of rosewood using molecular markers and its conservation management is available for populations in Brazil (Santos et al 2004, Santos et al 2008aAngrizani et al 2013), but is lacking for rosewood in Peru.…”

Rosewood, Aniba rosaeodora is an endangered species in Amazon forests and its natural stands have been heavily depleted due to over-exploitation for the cosmetic industry. This study aimed to investigate the genetic diversity and population structure of 90 rosewood accessions from eight localities in the Peruvian Amazon through 11 Inter Simple Sequence Repeats (ISSR) primers. The ISSR primers produced a sum of 378 bands, of which 375 (99.2%) were polymorphic, with an average polymorphism information content (PIC) value of 0.774. The mean effective number of alleles (Ne), Shannon informative index (I), gene diversity (He) and total gene diversity (Ht) were 1.485, 0.294, 0.453 and 0.252, respectively. Analysis of molecular variance (AMOVA) showed the presence of maximum variability within populations (88%). The Structure algorithm, neighbor joining and principal coordinate analysis (PCoA) grouped the 90 rosewood accessions into three main populations (A, B and C). Diversity indices at the inter-population level revealed a greater genetic diversity in population A, due to higher gene flow. The neighbor-joining analysis grouped populations A and B, while population C was found to be divergent at the inter population level. We concluded that population A reflects higher genetic diversity and should be prioritized for future management and conservation plans.

“…Despite the higher concentration of linalool (45.0%), a specimen collected from Santarém (Pará state, Brazil) also showed β-phellandrene (17.3%) and α-phellandrene (4.1%) in the EO of the aerial parts (leaves and thin stems). The oxygenated sesquiterpenoid -eudesmol was detected in low amounts (2.1%) [14].…”

Essential oils (EOs) from leaves and branches of Aniba parviflora (Meisn.) Mez were obtained by hydrodistillation and their chemical compositions determined by gas chromatography-mass spectrometry. Oxygenated sesquiterpenoids were the most representative compound class in both EOs ( 40%). However, the leaf EO was rich in β-phellandrene (15.1%), linalool (14.1%), and -eudesmol (12.9%). The EO from the branches showed high concentrations of -eudesmol (16.8%), β-caryophyllene (15.7%), linalool (12.4%), β-phellandrene (6.7%), and bicyclogermacrene (6.0%). The EOs were screened for radical-scavenging activity using the DPPH assay. In the DPPH assay, the EOs showed an antioxidant activity with TEAC values of 296.8 ± 20.2 and 357.3 ± 43.8 mg.TE.mL-1 , about one-third that of the Trolox standard. The EOs were subjected to antibacterial screening and displayed promising activity against Escherichia coli (MIC < 19.5 µg.mL-1). In addition, the EOs were tested for cytotoxic activity against MCF-7 breast tumor cells and the leaf EO (IC 50 = 67.9 ± 3.0 µg.mL-1) was more active than that from the branches (IC 50 = 102.2 ± 3.0 µg.mL-1).

“…On the other hand, these species presented distinct scents, despite the significant linalool content in their oils. An olfactory analysis of EOs from A. rosaeodora and A. parviflora, performed by enantioselective gas chromatography coupled to olfactometry, showed a significant difference between these oils [12,43]. In addition, the aromas extracted from the leaves of A. parviflora and A. rosaeodora by solid-phase microextraction (SPME), monitored by electrospray ionization mass spectrometry, and followed by PCA multivariate statistical analysis, showed a high efficiency at distinguishing the samples, as well as at separating them by collecting data, indicating the influence of the maturation stage on their chemical composition [44].…”

Essential Oil Composition and DNA Barcode and Identification of Aniba species (Lauraceae) Growing in the Amazon Region

Lauraceae species are widely represented in the Amazon, presenting a significant essential oil yield, large chemical variability, various biological applications, and high economic potential. Its taxonomic classification is difficult due to the accentuated morphological uniformity, even among taxa from a different genus. For this reason, the present work aimed to find chemical and molecular markers to discriminate Aniba species collected in the Pará State (Brazil). The chemical composition of the essential oils from Aniba canelilla, A. parviflora, A. rosaeodora, and A. terminalis were grouped by multivariate statistical analysis. The major compounds were rich in benzenoids and terpenoids such as 1-nitro-2-phenylethane (88.34–70.85%), linalool (15.2–75.3%), α-phellandrene (36.0–51.8%), and β-phellandrene (11.6–25.6%). DNA barcodes were developed using the internal transcribed spacer (ITS) nuclear region, and the matK, psbA-trnH, rbcL, and ycf1 plastid regions. The markers psbA-trnH and ITS showed the best discrimination for the species, and the phylogenic analysis in the three- (rbcL + matK + trnH − psbA and rbcL + matK + ITS) and four-locus (rbcL + matK + trnH − psbA + ITS) combination formed clades with groups strongly supported by the Bayesian inference (BI) (PP:1.00) and maximum likelihood (ML) (BS ≥ 97%). Therefore, based on statistical multivariate and phylogenetic analysis, the results showed a significant correlation between volatile chemical classes and genetic characteristics of Aniba species.
