The present study aimed to evaluate the chemical composition, antioxidant potential, and the cytotoxic and antimicrobial activity of the essential oil of the plant species Tithonia diversifolia (Hemsl) A. Gray. The essential oil obtained was used to identify the chemical compounds present through the techniques of GC-MS and NMR. The antioxidant potential was calculated by the sequestration method of 2,2-diphenyl-1-picrylhydrazyl. For cytotoxic activity, the larval mortality of Artemia salina was evaluated. The main chemical constituents identified are αpinene (9.9%), Limonene (5.40%), (Z)-β-ocimene (4.02%), p-cymen-8-ol (3.0%), Piperitone (11.72%), (E)-nerolidol (3.78%) and Spathulenol (10.8%). In the evaluation of the antimicrobial activity, bacterial strains of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa were used. The results showed that the bacterium E. coli were more susceptible to the presence of the essential oil, presenting minimal inhibitory concentration at the concentrations that were exposed. The essential oil presented antioxidant activity of 54.6% at the concentration of 5 mg·mL−1 and provided a CI50 of 4.30. It was observed that the essential oil of this species was highly toxic against A. salina lavas, as its cytotoxic activity showed an LC50 of 3.11. Thus, it is concluded that T. diversifolia oils are effective in inhibiting bacterial growth and reducing oxidative stress.

“…Piperitone was found in all samples of P. chimonanthifolium. This monoterpene is the major compound in all hydrolates and in the essential oils of the stem and leaf, and the second most abundant compound in the essential oil of inflorescence [35]. In case of C. subhirtella and C. serrulata benzaldehyde was the key component of the essential oils, while benzaldehyde, as well as mandelonitrile was the principal compound of hydrolates [19].…”

Hydrolates, also referred to as hydrosols, floral or distillate waters, as well as aromatic waters, are produced in the same isolation process with essential oils by steam distillation. A small amount of essential oil constituents is dissolved in hydrolates providing specific organoleptic properties and flavor, as well as biological activity which makes them useful as raw material in many industries. Their popularity is still on the rise, especially in aromatherapy. The objective in this review is to analyze the chemical compositions of hydrolates and their corresponding essential oils, as well as biological activity of hydrolates (antimicrobial, antioxidant and antiinflamatory) and potential uses, not only in food industry for flavoring, and preservation of fresh-cut fruits and vegetables, but also as functional (soft) drinks. However, hydrolates can be used in aromatherapy and cosmetics, as well as in organic agriculture and aquaculture.

“…The extracts were analyzed from electron impact ionization mass spectrometry (EI-MS) at 70eV, and the compounds were identified in scan mode with positive polarity of ions 20-300 m/z with a time of 250.0 ms. All the essential oils were injected with a volume of 1 µL, using a split ratio of 1:350 for C. ladanifer and T. capitata, and 1:100 for H. italicum, which was previously diluted with an organic solvent. Regarding the hydrolates of H. italicum, O. basilicum and T. capitata, they were subjected to a liquid-liquid extraction (LLE) with an organic solvent (hexane) (Collin and Gagnon, 2016;Riani et al, 2017). The aqueous phase was separated from the organic phase, and the organic phase was injected and analyzed using the same chromatographic method as essential oils.…”

The demand for natural-based products for industrial applications is increasing sharply and therefore the search for new alternatives to the plants traditionally used is growing. These alternative plants can be an important source of bioactive compounds under a circular economy approach. Considering the potential future use of new plant extracts by the industry, it is necessary to assess the risk associated with their introduction into the ecosystem. This work aims to provide an insight into the volatile profiles and evaluate the potential (eco)toxic effects of essential oils (EO's) and hydrolates of four plant species, namely rockrose ( Cistus ladanifer ), curry plant ( Helichrysum italicum ), conehead thyme ( Thymbra capitata ) and basil ( Ocimum basilicum ). Chemical analysis was performed by GC-MS and acute toxicity tests were performed using the model organism Daphnia magna . The essential oil and the hydrolate from H. italicum , as well as all the other hydrolates caused no immobilization up to the highest concentrations tested, suggesting that all hydrolates present low to no risk towards D. magna. Similarly, the essential oil of H. italicum , presented negligible risk towards D. magna . For C. ladanifer and T. capitata essential oils, the EC 50 (the concentration estimated to immobilize 50 per cent of the Daphnia ) at 48h varied from 199.7 mg/L and 12.05 mg/L, respectively. The essential oil from C. ladanifer was mainly characterised by monoterpene hydrocarbons, while the H. italicum was richer in sesquiterpene hydrocarbons. Both essential oil and hydrolate from T. capitata contained exclusively monoterpene hydrocarbons with a particularly high content of carvacrol. The higher acute toxicity of T. capitata essential oil can be attributed to the high amount of carvacrol present in the distillate. Overall, of the essential oils and hydrolates tested, all can be classified as practically non-toxic, except for T. capitata essential oil that, according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations, can be classified as moderately toxic.
