Abstract: Secondary metabolites are present in essential oils with characteristic aromas that reflect the chemical properties of the plants from which they are derived. They have been widely used across various cultures throughout history, particularly in traditional medicine, aromatherapy, cosmetics, and perfumery. A chemotype refers to the chemical variation within the same plant species, influenced by climatic, edaphic, or extraction technique factors. This study aimed to identify chemotypes of the essential oil from the species M. azurea, which is rich in mono- and sesquiterpenes. Data were gathered through a literature review, and compound identification was performed using gas chromatography and mass spectrometry. To identify the chemotypes, hierarchical cluster analysis and principal component analysis (PCA) were conducted. The cluster analysis, using the Ward linkage method, identified three groups. Similarly, PCA revealed three principal components in the grouping. M. azurea exhibits a characteristic essential oil profile with the presence of β-copaen-4α-ol and myrtenal, regardless of the extraction method or geographical location. The concentration of β-copaen-4α-ol significantly contributed to the variability among the groups.
