A B S T R A C TThe extraction of phenolic compounds from walnut leaves (Juglans regia L.) was optimized using heat-assisted extraction and deep eutectic solvents based on choline chloride and carboxylic acids. A preliminary solvent screening was performed using a selected group of carboxylic acids as hydrogen bond donors, showing that the highest extraction yield of phenolic compounds was obtained using choline chloride mixtures with butyric or phenylpropionic acid at a mole ratio 1:2, with 20% of water (w/w). The extraction conditions (time, temperature and water proportion) were then optimized by an experimental design, assisted by response surface methodology. To evaluate the response, the three most abundant compounds identified by HPLC (neochlorogenic acid, quercetin 3-O-glucoside and quercetin O-pentoside) were quantified. Additionally, the solid/liquid ratio effect at the optimal conditions, in dose-response format, was studied in view of its upscale, not showing any significant decrease until 140 g/L. The results here presented provide valuable information towards the design of a process in a pre-industrial form for the extraction of phenolic compounds from J. regia leaves using deep eutectic solvents.

“…Ercisli [26] reported for R. dumalis, R. canine, R. villosa and R. pisiformis, a range of 727 -943 mg/100ml, ranging from 300 to 4000 mg/100g of rose hip fruits. Cunja et al [9] reported for Rosa canina a Vitamin C content of 935 mg/100g of dw at midpoint of the ripening period. The values obtained in the present study are higher than those reported by Nadpal et al [8] Since a significant amount of rose hips is used in dried form (for infusions, soups and cream base yugourt, etc.)…”

“…Dehydration produces changes in fresh product, both edible and organoleptic quality and nutritional value of food [7]. Particularly ascorbic acid content is very sensitive to various forms of processes (temperature, salt and sugar concentration, pH, oxygen, enzymes, the initial concentration of the acid and the ascorbic/dehydroascorbic acid ratio) [9]. These factors are associated with the dehydration process used and the phytochemical composition of rose hips.…”

“…Our results indicate that the content of SST, in fresh rose hip fruit varies in a range between 32.55 and 55.20 ˚Brix, higher than the values reported by Uggla et al [29] for R. rubiginosa rose hips during maturation within a range from 13.1 to 25.7 ˚Brix. Balta et al [30] reported SST values for the genus of 22 -40 ˚Brix and Cunja et al [9] reported a total sugar content of 25.9 -48.0 mg/100g dw. The observed difference in values might be due to conditions such as the incidence of light on the plant, the degree of maturity, time and manner of fruit harvest.…”

We evaluated fruit availability, phytochemical characteristics and mineral content of R. rubiginosa L. rose hips, at two experimental sites in San Luis province: Potrero de los Funes-El Volcán (PF-V) and Estancia Grande (EG). Plant density was 70 plants/ha (1 ha = 10,000 m 2 ) in PF-V and 50 plants/ha in EG. Fruit availability (D F ) in fresh fruits (FF) was 4.39 kg (PF-V) and 3.10 kg (EG) during March, and decreased during June. Ascorbic acid in FF increased during ripening period, peaking on late April, early May, and diminished 75% -85% in dried fruits. Total soluble solids in FF ranged from 32.55 to 55.20 ˚Brix. Elements Ba, Ca, Fe, K, Zn and Cu, determined by inductively coupled plasma optical emission spectrometry (ICP-OES), were significant for human health. Dried fruits maintain a high level of ascorbic acid, a characteristic added to content of mineral elements, particularly calcium content, providing an important nutritional value to R. rubiginosa rose hips.

BACKGROUND: Japanese dogwood (Cornus kousa Burg.) is a popular ornamental plant which develops edible compound fruit utilized in traditional Asian medicine. Previous compositional studies have focused on a small fraction of secondary metabolites at a single maturity stage. In order to address the question of optimal ripeness of Japanese dogwood fruit for consumption the study provides a comprehensive insight into its primary and secondary metabolic profile. RESULTS: The aim of the study was to investigate biochemical composition and morphological traits of Japanese dogwood (Cornus kousa Burg.) fruit at four maturity stages: GF, green fruit; BF, fruit with a defined red blush; RF, ripe fruit; OF, over-ripe fruit. Fruit was characterized by a nearly spherical shape, decreased water content in later stages of ripeness and highest a* values at RF and OF stages. Total sugars increased significantly from GF to OF stage and total organic acids and vitamin C decreased with maturation. Japanese dogwood fruit was characterized by four major phenolic groups: anthocyanins (three), flavonols (eight) hydroxycinnamic acids (three) and flavonoids (one) as well as by four lipophilic antioxidants: tocopherols (two), xanthophylls (five), carotenes (two) and chlorophylls (two). The progression of fruit ripening caused faster accumulation of individual phenolic compounds and lipophilic antioxidants which resulted in significantly higher total phenolic content at the RF and OF stages. CONCLUSION: Japanese dogwood fruit is a rich alternative source of ascorbic acid, ⊍-tocopherol, flavonols and anthocyanins and should be consumed fresh at fully developed red colour of compound berries when their composition is optimal.
