Abstract The present study aimed to chemically characterize 31 accessions and seven cultivars of basil. The percentage composition of the essential oils of the accessions and cultivars was based on the 14 most abundant constituents: The genetic materials were classified into eight clusters according to the chemical composition of the essential oils: Introduction The genus Ocimum L.
Lamiaceae comprises more than 30 species that are found in tropical and subtropical regions [ 1 ]. Due to their economic importance, the most cultivated species in the world are O. Basil Ocimum basilicum L.
Basil is economically important due to the use of its essential oil in hygiene and cleaning products, perfumes, and cosmetics and as a local anesthetic and antiseptic [ 4 ]. Furthermore, basil essential oil has been tested in the control of plant pests [ 56 ] and diseases [ 7 ] and has been shown to act as an antioxidant [ 8 ] and an antimicrobial [ 9 ].
Basil has a complicated taxonomy due to the numerous varieties of cultivars within the species that do not differ significantly in morphology.
Thus, the classification of genotypes only by morphological features becomes difficult due to anthropogenic interference with selection, cultivation, and hybridization [ 10 ]. Due to the hybridization of several species and varieties, there is a wide variability of the chemical constituents [ 11 ].
Chemical characterization can be used to separate the accessions based on the presence or concentration of specific substances and to determine the intrinsic variability or variability among accessions of the same species [ 10 ].
Despite the wide variation in the chemical composition of basil essential oil within the same species, monoterpenes and phenylpropanoids predominate [ 1213 ]. Genotype characterization based on the chemical constitution of the essential oil has been used in several cultures such as Zingiber officinale [ 14 ] and Hyptis suaveolens [ 15 ], including plants of the genus Ocimum, with emphasis on O.
Several studies assessing the chemical composition of 18 basil essential oils observed that the samples distributed into seven distinct types, each one presenting as the major volatile compound among the following: A total of 27 basil cultivars were characterized according to the chemical composition of their essential oils, and the cultivars were grouped into five different types: The chemical characterization of 38 basil genotypes resulted in seven groups: Morphological and agronomic characterization of 55 basil accessions showed genetic variability in Ocimum sp.
The present study observed genotypic variations in relation to the content and yield of essential oil, and promising genotypes were noted for the development of cultivars with high content and yield of essential oil rich in linalool and other active ingredients [ 18 ].
These comparative studies show a high variation in the chemical composition of basil essential oil and how important it is to conduct research investigating these chemical characterizations because the identification of types of basil helps in pharmacological, medicinal, and phytopathological studies.
Thus, the present study aimed to chemically characterize the volatile constituents of accessions and cultivars of O. Materials and Methods 2.
