“…Higher availability of macronutrients enables increased EO concentrations in basil plants, accordingly with the percentage of wastewater used (Villanova et al 2018). These authors reported that the supply of major N concentrations to Ocimum gratissimum L. improved the growth and EO production by the plants.…”

Essential oils (EO) are volatile compounds with complex chemical compositions that are derived from the secondary metabolism of aromatic herbs. There are several applications of EO in the industrial and medical sectors. Basil (Ocimum sp.) is one of the most important EO-producing aromatic herbs. In this study, EO content (EOC) and linalool content (LC) in basil irrigated with reclaimed water were investigated. Plant development parameters, nutrient absorption and crude protein (CP) content were also evaluated. The experiment was conducted in a greenhouse, with five different treatments and five repetitions each. Compared with treatments only using water, the results of those with reclaimed water irrigation showed higher nutrient absorption, CP contents (in their foliar tissue), length of plant branches, foliar biomass weights, and EOC and LC. EOC reached up to 0.58% of the dry biomass and LC was up to 5.84% of EO mass. In practice, it is estimated that around 5.8 kg of EO and 0.34 kg of linalool can be obtained from one ton of dry basil biomass.

“…In addition, reduced growth as a result of the drought was also reported on O. × africanum [14,17] and O. gratissimum [13,16]. Almost all the evidence revealed that drought restricted the growth of Ocimum species and other medicinal and aromatic plants.…”

“…Plants are known to undergo biochemical, physiological, and developmental changes as a result of drought stress [11,14,27]. Consequently, several scientists have examined the relationship between water stress and essential oil accumulation in certain Ocimum species, and their results indicated restricted plant growth and slightly enhanced essential oil content [12][13][14][15][16][17]. In contrast, others found that drought stress having no significant effect on the essential oil content of Thymus vulgaris and Hyssopus officinalis [18].…”

Morphological and biochemical responses of selectedOcimumspecies under drought

Summary Introduction: Drought stress is known to change biochemical activities resulting in altered plant growth and development. Objective: Due to the shortage of research evidence in a certain taxa of basil, it is imperative to examine the relationship between drought stress and morphological changes as well as essential oil accumulation. Methods: An open field experiment was conducted in 2020 to determine the effects of drought stress on the morphological and biochemical responses of selected Ocimum species. Five basil species, namely O. basilicum ‘Genovese’, O. basilicum ‘Ohre’, O. × africanum, O. americanum, O. selloi, and O. sanctum ‘Krishna’ were grown under irrigated (control) and non-irrigated (drought stress treatment) plots with two block replications. Results: The result showed that irrigation had a positive effect on production. Consequently, fresh and dry biomass yields were higher on irrigated plots by 39% and 33%, respectively. No significant changes were detected between the treatments in essential oils (EO) yield and EO composition of major compounds. However, a slight increase in camphor (O. × africanum), nerol (O. americanum), and trans-β-caryophyllene (O. sanctum ‘Krishna’) ratios were observed under irrigation treatments. On the other hand, drought stress increased EO content, polyphenol content, and antioxidant capacity. Furthermore, drought stress had a positive effect on the ratios of 1,8-cineole (O. × africanum), and eugenol (O. sanctum ‘Krishna’). There is only a slight increase in EO content under drought stress, which is not comparable to the significant yield reduction recorded. Morphological and biochemical variations were also detected among basil species. Accordingly, higher biomass (616.33 g/plant) and EO yield (3.72 ml/100 g) among the species were obtained from O. basilicum ‘Genovese’ and O. × africanum, respectively. Conclusion: Irrigation is imperative for maximizing biomass and EO yield of tested basil species.

“…This trend is confirmed by official statistics: the European MAP market, albeit only for the primary production of MAPs, is valued at 4-5 million EUR (about 400,000-450,000 tonnes of herbs and dried herbs and more than 100,000 tonnes of essential oils) [12]. MAPs are marketed in many forms, including fresh, dried, and as herbal teas, and many are used to extract high-value chemicals, such as essential oils [49][50][51]. At present, about 25% of newly marketed medications are derived from natural compounds, the vast majority of which are MAPs [52].…”

Market Trends of Medicinal and Aromatic Plants in Italy: Future Scenarios Based on the Delphi Method

et al. 2023

View full text Add to dashboard Cite

The medicinal and aromatic plant (MAP) sector in Italy is a niche sector that is growing in terms of both primary production and consumption. These products seem to be important to address several global challenges, including climate change, biodiversity conservation, drought solutions, product diversification, product innovations, and the development of rural areas (rural tourism in primis). This study utilised the Delphi method to identify key factors and possible strategies that could be adopted for the future (the next 3–5 years) of the national MAP supply chain. The research involved the collaboration of 26 experts. Individual interviews, based on a semi-structured questionnaire, were carried out during the first round of the study. The information and the collected data were then analysed and depicted in a mental map. The Italian MAP sector suffers from competition from lower-cost imported products. Despite this, the experts predicted an expansion of the MAP sector regarding aromatic herbs and certain derivative products, such as dietary supplements, biocides, and essential oils. The experts anticipated the need to increase the adoption of digital innovations, of developing agreements among the actors of the supply chain, and of investing in the training of supply chain actors.
