Native wild edible greens usually include plants with widespread geographical ranges and represent a long tradition associated with well-documented health effects, especially in the frame of the Mediterranean diet. Although consuming local endemic and range-restricted plants as wild edible greens is rare, in some areas of Crete this is a long ethnobotanical tradition. The present study is focused on the phytochemical and nutritional element analyses of the edible parts of the wild-growing green Campanula pelviformis. To date, nine secondary metabolites have been isolated: lobetyolin (1), calaliukiuenoside (2), demethylsyrrigin (3), wahlenoside A (4), chlorogenic acid methyl (5) and butyl ester (6), nicotiflorin (7), rutin (8) and corchoionoside A (9). This first-time research on the phytochemical composition of this local endemic plant of Crete is a basic step in attempts to document its nutritional value, also allowing an exploration of its beneficial properties. The nutritional value of the Mediterranean diet owes much to the inclusion of native edible wild plants, which are abundant in mineral elements and bioactive compounds known to promote human health. Among these plants, the local Cretan endemic species C. pelviformis stands out as a rare and valuable source of wild edibles with traditional dietary significance in eastern Crete. This plant’s rich content of mineral elements and bioactive compounds makes it an intriguing subject for further research into the potential health benefits of wild plant consumption.

The purpose of this paper is to demonstrate a new discovery regarding the interaction between materials and very low radio frequencies. Specifically, we observed a feedback response on an inertia active sensor when specific frequencies (around 2–4 kHz) are used to irradiate targeted pharmaceutical samples like aspirin or paracetamol drugs. The characteristics of this phenomenon, such as excitation and relaxation time, the relation between deceleration and a material’s quantity, and signal amplitude, are presented and analyzed. Although the underlying physics of this phenomenon is not yet known, we have shown that it has potential applications in remote identification of compounds, detection, and location sensing, as well as identifying substances that exist in plants without the need for any processing. This method is fast, accurate, low-cost, non-destructive, and non-invasive, making it a valuable area for further research that could yield spectacular results in the future.

Scaligeria napiformis (Willd. ex Spreng) Grande is an underutilized wild edible plant associated with the Cretan flora and diet, yet cultivation-oriented information on its response to nutrient management remains limited. This study compared two practical foliar nutrient management regimes, including a biostimulant-containing foliar product (INM-b) and a conventional foliar fertilization regime (CovF), together with an untreated control (Ctrl). Relative chlorophyll status, assessed by SPAD, maximum quantum efficiency of PSII photochemistry (Fv/Fm), CIE L*a*b* leaf colour parameters, fresh and dry biomass, and macro- and micronutrient concentrations in the edible aerial parts were determined. Foliar nutrient management significantly affected the SPAD-based relative chlorophyll status, leaf colour, edible biomass and selected mineral elements, whereas Fv/Fm was not significantly affected by treatment. CovF was associated with the highest SPAD values, darker, greener and less yellow leaves, and the highest N, Zn and Fe concentrations. Both INM-b and CovF increased fresh and dry biomass relative to the Ctrl and increased the P, K and Mn concentrations, while Ca, Mg and B were not significantly affected. Because INM-b and CovF differed in nutrient composition, formulation and nutrient supply, the present design does not isolate the specific effect of the biostimulant-containing component. Therefore, these findings should be interpreted as preliminary responses of S. napiformis to the tested foliar management strategies under pot cultivation, requiring future validation through isonutrient-, factorial- and field-based experiments.
