Introduction: The aromatic plants have occupied an important place in the daily life of man. The excessive and repetitive use of drugs has led the body to develop resistance to their curative effects. Many authors have focused on the study of the therapeutic properties of essential oils in order to provide new remedies. They are used as a source of bioactive molecules of natural origin. Objective: The objective of this work is to contribute to the valorization of medicinal and aromatic plants of the Ivorian flora. We propose to determine the chemical composition and to evaluate the antioxidant activity by spectrophotometry of the essential oil. Materials and Methods: The plant material consists of the leafy twigs of C. odorata. The technical of steam distillation using a four-compartment stainless steel device was used to extract the essential oil from the plant matrix. The analysis of the essential oils was carried out on a GC chromatograph (7890A, Agilent Technologies) coupled to a mass spectrometer (5975C, Agilent Technologies). The antioxidant potential of the extracts was evaluated using the Blois method. Results: The essential oil obtained by steaming, with an aromatic odor and pale green color has a yield of (0.082 ± 0.004) %. Analysis of the chromatogram and mass spectra identified 24 phytocompounds (99.92%). The phytochemical composition is dominated by hydrocarbon sesquiterpenes (44.21%) followed by hydrocarbon monoterpenes (29.48%) and other compounds (26.23%). The major compound are α-pinene (17.79%), 6-propen-1-enylbicyclo [3.1.0] and hexan-2-one (14.95%) . Conclusion: The essential oil extract of C. odorata exhibits low antioxidant activity compared to vitamin C.
In this study, we were interested in the valuation of Ocimum gratissimum, an aromatic and medicinal plant of the Ivorian flora. The essential oils of the leafy branches of Ocimum gratissimum were extracted by hydrodistillation with a Clévenger-type device. The yield of the oils obtained increases from (0.05±0.01%) to (0.42±0.08%) depending on the drying time. The density of essential oils is almost constant at 0.80. The chemical composition of essential oils was identified after analysis of chromatograms and mass spectra. The number of phytocompounds also increases with the number of drying days from 32 to 37. These compounds are marked by the presence of hydrocarbon monoterpenes from (29.11% to 49.1%), and oxygenated from (40.33% to 50.02%) and the presence of hydrocarbon sesquiterpenes from (5.52% to 8.55%), and oxygenated from (0.80% to 2.16%). The number of major compounds is 5 on day 0 and decreases to 4 on the other days, and have the following proportions: thymol from (33.60% to 44.73%), β‑caryophyllene from (2.54% to 3.29%), para-cymene (12.32% to 25.60%), γ-terpinene (10.09% to 11.41%), Bis(2-ethylhexyl)phthalate (12.12% to 0.42%). bis (2-ethylhexyl) phthalate which is in the minority during the other drying days.
