“…Recently, their value has improved thanks to their proven nutraceutical properties [1][2][3]. In fact, some researchers have recognized wild edible plants as functional foods and as a new source of bioactive compounds that are beneficial to human health for their anti-inflammatory, antimicrobic, anticarcinogenic, cytotoxic and antiproliferative properties [4][5][6][7][8][9]. For example, a number of wild plants have been used in the diet including the stems and leaves of Sanguisorba minor, the fruit of Rosa canina, bellota acorns of Quercus ilex [5], leaves of Umbelicus rupestris (Salisb.)…”

Hydroponically Grown Sanguisorba minor Scop.: Effects of Cut and Storage on Fresh-Cut Produce

Wild edible plants have been used in cooking since ancient times. Recently, their value has improved as a result of the scientific evidence for their nutraceutical properties. Sanguisorba minor Scop. (salad burnet) plants were hydroponically grown and two consecutive cuts took place at 15 (C1) and 30 (C2) days after sowing. An untargeted metabolomics approach was utilized to fingerprint phenolics and other health-related compounds in this species; this approach revealed the different effects of the two cuts on the plant. S. minor showed a different and complex secondary metabolite profile, which was influenced by the cut. In fact, flavonoids increased in leaves obtained from C2, especially flavones. However, other secondary metabolites were downregulated in leaves from C2 compared to those detected in leaves from C1, as evidenced by the combination of the variable important in projections (VIP score > 1.3) and the fold-change (FC > 2). The storage of S. minor leaves for 15 days as fresh-cut products did not induce significant changes in the phenolic content and antioxidant capacity, which indicates that the nutraceutical value was maintained. The only difference evidenced during storage was that leaves obtained from C2 showed a lower constitutive content of nutraceutical compounds than leaves obtained from C1; except for chlorophylls and carotenoids. In conclusion, the cut was the main influence on the modulation of secondary metabolites in leaves, and the effects were independent of storage.

“…Regarding tannin content, it was concluded that SBPE has 1.14% and BBPE has 1.47% [19]. The results showed that the beech bark extracts contained considerable quantities of aromatic compounds, such as (+)-catechin, (−)-epicatechin, quercetin-O-hexoside, taxifolin-O-hexosides, taxifolin-O-pentosides, B-type and C-type procyanidins, syringic acid, and coumaric acid-di-O-glycosides, coniferyl alcohol and sinapyl alcohol-glycosides, and (+) and (−) glucodistylin [11,18,19]. The compounds identified in spruce bark extract by HPLC were gallic acid (3.19 mg GAE/100 g), catechine (31 mg GAE/100 g), and vanillic acid (39.4 mg GAE/100 g) [13].…”

Over the past few years, special attention has been paid to biomass valorization. The aim of this paper is to evaluate the effect of the phenolic rich extracts obtained from raw materials on the growth and development of lemon balm (Melissa officinalis L.). The extracts were obtained from the bark of spruce (Picea abies (L.) H. Karst) and beech (Fagus sylvatica L.) separated as waste product during wood processing. The growth and development of the plants was assessed by measuring elongation of vegetative organs, biomasses including root, stem, and leaf, and photosynthetic pigment content. In addition, the analysis of some histo-anatomic characteristics of the vegetative organs were made. Elongation biomasses and photosynthetic pigments concentration presented higher values in case of plants treated with beech bark phenolic extract compared to control plants. The spruce bark phenolic extract had a stimulatory effect on the germination but inhibited the growth and development of the plants. Both extracts increased the percentage of lignification in stems. These findings could contribute to the development of natural and eco-friendly substances that favor cultivation of lemon balm plants. Future research is needed in order to identify potential qualitative and quantitative changes in the essential oil of the aromatic plant treated with the tested solutions.

“…After processing, a significant amount of bark is obtained. Thus, spruce and beech bark are considered a waste product in the wood industry [ 11 ]. Our previous results have shown that beech and spruce bark crude extract has antimicrobial, antitumoral and bioregulator effect in sage plants [ 10 , 11 , 12 ].…”

This paper aims to assess the biological responses of Lavandula angustifolia Mill. to beech and spruce bark crude extract application. Thus, the biological activity of bark extracts was assessed by determining the germination capacity, biomass production, histo-anatomical aspects and photo-assimilatory pigment accumulation, and by quantitative and qualitative volatile compounds analysis. The application of spruce bark extract (500 mg dry bark/100 mL solvent) resulted in a better development of the leaf tissue and an increase in foliar biomass. We observed the stimulating effect of photo-assimilating pigments accumulation, for all experimental variants, compared to the control. Also, the amount of volatile oil was significantly higher in the treated plants with spruce bark extract (500 mg dry bark/100 mL solvent). Some volatile compounds (cyclen, borneol, cryptone, santalen, and caryophyllene oxide β—farnesene) were identified only in the experimental variants. Also, in the experimental variants, an increase in the quantity of limonene, linalyl acetate and lavandulol was observed. These preliminary results showed that the beech and spruce bark extracts can have biological activities and influence the production of volatile oil in Lavandula angustifolia, causing significant changes in the phytochemical profile of the essential oil. Thus, forest waste bark extracts could be recommended as natural bioregulators in lavender crops.
