Effect of Environmental Conditions on the Yield of Peel and Composition of Essential Oils from Citrus Cultivated in Bahia (Brazil) and Corsica (France)

Abstract

The cosmetic and fragrance industry largely exploits citrus essential oils (EOs) because of their aromatic properties. EO compositions are complex and differ between fruit pericarp (PEO) and leaf (LEO). Citrus fruit grow in many countries under very different climates. Seventeen citrus cultivars were selected and their similarities between the two collections were verified by SSR (Single Sequence Repeat) and InDel (Insertion and Deletion) markers to assess the effects of the environment and cultivation practices on the EO yield and composition. LEOs and PEOs were extracted by water distillation and analyzed by GC-MS. PEO yields were generally higher in Corsica than in Bahia, especially in the citron family. PEOs in this family were richer in limonene in Bahia than in Corsica while, conversely, neral, geranial and derivatives were present in a higher proportion in Corsican varieties. A few minor components were site-specific, such as nookaton, a pummelo-specific compound that was not present in grapefruit cultivated in Bahia. If climate change over the last 20 years has not affected the PEO composition in Corsica, the contrasted environmental conditions and cultural practices between Bahia and Corsica could possibly explain the EO variations.

Potent Anti-Cutibacterium acnes Activity of the Essential Oils Derived from Allium sativum, Gerdenia jasminoides, and Hedychium coronarium Cultivated in Thailand

“…Temperature and precipitation levels were used to assess the climate at various locations. EO yields have been shown to be reduced by higher average temperatures and radiation (Luro et al 2020). The garlic oil showed the best bacterial tests and was similar to Chekki et al (2014).…”

The Potency of Locally Available Orange Peel Essential Oil as A Feed Additive to Improve Performances of Poultry

“…Grapefruit (Citrus maxima) or pomelo is a species of tropical fruit plant that is widespread and cultivated in Southeast Asia and the East Indian Islands [2]. Grapefruit is characterized by leaves and fruit that are larger than other types of citrus and have a fragrant aroma when the flowers bloom.…”

Investigation of Diversity by Analyzing the Polymorphism of SSR Markers and the Composition of Leaf and Fruit Essential Oils of 72 Mandarins (Citrus reticulata Blanco)

“…The composition of essential oils can fluctuate depending on many factors such as the environment [20], the stage of fruit maturity [21], the rootstock [22,23], extraction method [24], the health of the tree [25,26], the genotype and the climate changes [27]. Variations in PEO composition can be very significant, as in the case of bergamot PEO, where the proportion of linalyl acetate varied during the ripening period from 17.07% to 40.37% [27].…”
