“…This event may be due to evaporation, oxidation, and the occurrence of undesirable changes during the time of storage [83,84]. Our results are in agreement with similar findings on Lemon balm (Melissa officinalis L.) [26], Hyptis pectinata [85], and Thymus daenensis [86]. It might be found that the EO keeps its original quality when stored at freezer temperature.…”

Sour orange (Citrus aurantium L.) is a tree with medicinal properties. This study assessed the impact of various storage conditions and times on the Essential Oil (EO) content of sour orange blossoms. The changes in the EO composition were recorded at the beginning of extraction and during three, six, and nine months of storage at the temperature of 4 °C (refrigerator), -20 °C (freezer), and 25 °C (room temperature) under conditions of light and darkness. According to the Gas Chromatography (GC, FID detector) and Gas Chromatography-Mass Spectrometry (GC-MS, FID detector) results, 35 compounds were identified. Linalool acetate (14.56-31.4%), linalool (18.9-23.1%), limonene (7.51-15.3%), farnesol (2.1-9%), nerolidol (6.1-8.9%), β-pinene (5.7-8.7%), trans-β-ocimene (0-7.9%), and geranyl acetate (4.2-5.7%) constituted the major EO components in different storage treatments. After nine months, linalool acetate climbed by more than twice as much. Overall, the principal EO compositions are significantly impacted by the storage circumstances. Such knowledge is essential for the food and pharmaceutical industries to use EO effectively in their intended products.

“…The DNA barcode can only authenticate the medicinal plant while the chemical profile provides information on the presence and concentration of compounds with pharmacological activity [ 63 ]. This diversity of compounds is generally determined by the genetic constitution of the plant, although environmental factors may also influence the type, amount, and concentrations of the compounds present in the essential oil [ 64 ].…”

Essential Oil Chemotypes and Genetic Variability of Cinnamomum verum Leaf Samples Commercialized and Cultivated in the Amazon

Cinnamomum verum (Lauraceae), also known as “true cinnamon” or “Ceylon cinnamon” has been widely used in traditional folk medicine and cuisine for a long time. The systematics of C. verum presents some difficulties due to genetic variation and morphological similarity between other Cinnamomum species. The present work aimed to find chemical and molecular markers of C. verum samples from the Amazon region of Brazil. The leaf EOs and the genetic material (DNA) were extracted from samples cultivated and commercial samples. The chemical composition of the essential oils from samples of C. verum cultivated (Cve1-Cve5) and commercial (Cve6-c-Cv9-c) was grouped by multivariate statistical analysis of Principal Component Analysis (PCA). The major compounds were rich in benzenoids and phenylpropanoids, such as eugenol (0.7–91.0%), benzyl benzoate (0.28–76.51%), (E)-cinnamyl acetate (0.36–32.1%), and (E)-cinnamaldehyde (1.0–19.73%). DNA barcodes were developed for phylogenetic analysis using the chloroplastic regions of the matK and rbcL genes, and psbA-trnH intergenic spacer. The psbA-trnH sequences provided greater diversity of nucleotides, and matK confirmed the identity of C. verum. The combination of DNA barcode and volatile profile was found to be an important tool for the discrimination of C. verum varieties and to examine the authenticity of industrial sources.

“…The genetic constitution generally determines the diversity of secondary metabolites produced by plants. However, various biotic and abiotic factors can alter the metabolic pathway of secondary metabolites, leading to the biosynthesis of distinct constituents of the oil, differing from the genetic profile [52,53] …”

“…However, various biotic and abiotic factors can alter the metabolic pathway of secondary metabolites, leading to the biosynthesis of distinct constituents of the oil, differing from the genetic profile. [52,53] Chemical and genetic correspondences were observed for the species Nectandra cuspidata and N. puberula. The essential oils of this subclade were rich in sesquiterpene hydrocarbons and characterized by the common presence of (E)-caryophyllene and bicyclogermacrene.…”

The Ocotea complex accommodates most of the taxonomic diversity of Neotropical Lauraceae with economic importance and biological potential attributed to their essential oils (EOs) and extracts. However, the botanical taxonomy has had limitations due to the difficulty of identifying and delimiting species and genera. The chemical and molecular markers of Ocotea complex species in Pará state, Brazil, were assessed according to their EO compositions and DNA sequences of matK, trnL-trnF, and ITS regions. The multivariate analysis of EOs constituents has classified them into two main clusters characterized by oils rich in (I) terpenoids and phenylpropanoids and (II) sesquiterpenes. We conducted a phylogenetic analysis of species based on DNA barcode sequences on the Bayesian Inference (PP: 0.70 -1,0) and Maximum Likelihood (BS: 72 -100 %). The comparison between the volatile profiles and phylogenetic data indicates two main groups for these species collected from the Ocotea complex.
