“…Although more appreciated in the market for its content in CBDs from plant's inflorescences and for the wide utilization of the aerial parts, here we applied and tested aeroponics to C. Sativa, whose roots exhibit a fairly high content in potentially valuable constituents characterized by pharmacological, nutraceutical and cosmeceutical attractive activities. Notably, we show that the yield of these components on a per plant basis was invariably and significantly higher in AP and AEP as compared to SP, and that using salicylate as elicitor [20,21] accumulation of all bioactives could be attained (with the exception of β-sitosterol which only slightly decreased as compared to AP).…”

Cannabis Sativa L. has been used for a long time to obtain food, fiber and as a medicinal and psychoactive plant. Today the nutraceutical potential of C. Sativa is being increasingly reappraised; however, C. Sativa roots remain poorly studied, despite citations in the scientific literature. In this direction, we identified and quantified the presence of valuable bioactives (namely β-sitosterol, stigmasterol, campesterol, friedelin and epi-friedelanol) in the root extracts of C. Sativa, a finding which might pave the way to the exploitation of the therapeutic potential of C. Sativa in all its parts. To facilitate roots harvesting and processing, aeroponic (AP) and aeroponic elicited cultures (AEP), have been set up and compared to soil-cultivated plant (SP): interestingly a considerable overgrowth of the plants - particularly of roots - and a significant increase (up to 20 fold in the case of β-sitosterol) in the total content of the above roots’ bioactive molecules have been observed in AP and AEP. In conclusion aeroponics, an easy, standardised, free of contaminant cultivation tecchnique, allows an ease harvesting/processing of roots along with a greater production of their secondary bioactive metabolites which could be utilized in the formulation of health promoting and health care products.

“…Salicylic acid is a hormone-like substance that plays an important role in the regulation of plant growth and development [11]. Exogenous application of salicylic acid is presented as a highly potent, cost effective, ecofriendly and quick strategy to enhance the synthesis and accumulation of secondary metabolites in plants [12]. The effect of exogenous salicylic acid depends on several factors such as the species and developmental stage of the plant, the mode of application, concentration of salicylic acid and its endogenous level in the given plant [13].…”

Background: Purple coneflower, Echinacea purpurea (L.) Moench, has long been used in herbal remedies to prevent and treat a wide range of diseases like common cold, simple cough, pulmonary infections, dermatologic disorder and chronic diseases due to immunodeficiency. Objective: The present study was conducted to investigate the effects of salicylic acid and yeast extract foliar application on caffeic acid derivatives production in coneflower. Methods: Two factorial experiments were performed individually under greenhouse conditions during the years 2017-2018. In the first experiment, the effect of salicylic acid (0, 80, 160 and 320 mg/L) and each at four exposure times (24, 48, 72 and 96 hours) was studied. Also, in the second experiment, the effect of yeast extract (0, 0.75, 1 and 1.5 g/L) and each at four exposure times was investigated. Results: The results indicated that main effects and interactions of different concentrations of salicylic acid and yeast extract at different exposure times on caffeic acid derivatives content were significant (P ˂ 0.01). The highest cichoric acid, caftaric acid and echinacoside production was obtained after 96 hours of treatment at 160 mg/L salicylic acid treated plants. The highest cichoric acid production 7.150 mg/g DW was obtained after 96 hours of treatment at 1.5 g/L yeast extract treated plants, this was 3.58fold higher compared to respective control. The lowest level of caffeic acid derivatives production was observed in control plants. Conclusion: In conclusion, salicylic acid and yeast extract foliar application have a positive effect on caffeic acid derivatives production in Echinacea purpurea aerial parts.
