lipophilic extracts isolated from european cranberry bush Viburnum opulus and sea buckthorn hippophae rhamnoides berry pomace by supercritical co2 promising bioactive ingredients for foods and nutraceuticals
Food Chemistry, 2021Co-Authors: Lijana Dienaitė, Renata Baranauskienė, Petras Rimantas VenskutonisAbstract:Abstract Lipophilic extracts of Viburnum opulus (VOP) and Hippophae rhamnoides (SBP) berry pomace recovered by supercritical CO2 (SFE-CO2) were analysed by UPLC-Q-TOF-MS and GC×GC-TOF for their triacylglycerol, tocopherol, phytosterol and fatty acid composition, while oxidative stability was evaluated by Oxipres and Rancimat methods. SFE-CO2 recovered 16.99% and 26.24% of lipids from SBP and VOP, respectively. Linoleic, linolenic, oleic, palmitic and palmitoleic acids were major in SBP oil, while VOP oil was composed of almost equal amounts of linoleic and oleic acids. Therefore, remarkably higher diversity of triacylglycerols was identified in SBP. The content of β-sitosterol and α-tocopherol was 359.5−514.5 and 65.38−118.6 mg/100 g, respectively. Hydrocarbons were other quantitatively important lipophilic components, including health beneficial squalene. All extracts improved oxidative stability of mayonnaise. The extracts of berry processing by-products by green extraction method contain valuable bioactive constituents and could be of high interest for applications in functional foods and nutraceuticals.

valorization of european cranberry bush Viburnum opulus l berry pomace extracts isolated with pressurized ethanol and water by assessing their phytochemical composition antioxidant and antiproliferative activities
Foods, 2020Co-Authors: Lijana Dienaitė, Milda Pukalskienė, Carolina V Pereira, Ana A Matias, Petras Rimantas VenskutonisAbstract:Defatted by supercritical CO2, Viburnum opulus berry pomace (VOP) was subjected to consecutive extraction with pressurized ethanol (E) and water (W) and yielded 23% of VOP-E and 8% of VOP-W, respectively. The major phytochemical groups covering 42 identified and quantified constituents in VOP extracts were organic and phenolic acids, iridoids, quercetin and (epi)catechin derivatives, flavalignans, procyanidins, and anthocyanins. The on-line HPLC-DPPH•-scavenging assay revealed the presence of numerous antioxidants. VOP-E had a higher total phenolic content, was a stronger antioxidant (equivalent to 0.77, 0.42, and 0.17 g trolox/g in oxygen radical absorbance capacity (ORAC), ABTS, and DPPH assays, respectively), and recovered the major part of phenolics from the pomace; however, both extracts demonstrated similar antioxidant activity in the cellular assay. VOP-E inhibited HT29 cancer cells at non-cytotoxic concentrations. The results of this study revealed that VOP contains valuable phytochemicals possessing antioxidant and antiproliferative activities. Consequently, extracts from VOP substances may be of interest in developing functional ingredients for healthy foods, nutraceuticals, and cosmeceuticals.

supercritical carbon dioxide and pressurized liquid extraction of valuable ingredients from Viburnum opulus pomace and berries and evaluation of product characteristics
Journal of Supercritical Fluids, 2017Co-Authors: Paulius Kraujalis, Vaida Kraujalienė, Rita Kazernaviciūtė, Petras Rimantas VenskutonisAbstract:Abstract Supercritical carbon dioxide extraction (SFE-CO2) of Viburnum opulus L. fruits and pomace was optimized using 2 level factorial and central composite design (CCD). The effects and interactions of temperature (T), pressure (P), extraction time (t) and CO2 flow (v) were estimated for the washed V. opulus berry pomace, while 2 most significant factors, P and t were used further to estimate the coefficients of quadratic model and to find optimal extraction parameters by response surface methodology (RSM) for the unwashed pomace. The highest extract yields at optimal parameters (P = 55–57 MPa, t = 120–131 min, T = 50 °C and v = 2.5 L min−1) from washed, unwashed berry pomace and dried whole berries were 19.1, 14.6 and 6.6%, respectively. The oil in lipophilic fractions was composed mainly of oleic (42–51%) and linoleic (42–46%) fatty acids; it contained 963–1157 mg kg−1 tocopherols. SFE-CO2 residue was consecutively re-extracted by pressurized acetone, water and ethanol yielding 11.59 ± 0.95, 27.58 ± 0.79 and 30.71 ± 0.59% of extracts, respectively, which demonstrated strong antioxidant capacity in DPPH and ABTS radical scavenging, oxygen radical absorbance capacity (ORAC) and total phenolics assays. In total, biorefining of unwashed pomace yielded 62.11% of extracts from the initial plant material. The fractions obtained may be considered as valuable functional ingredients for foods, nutraceuticals and other applications.

Antimicrobial activity of Viburnum opulus fruit juices and extracts
Journal für Verbraucherschutz und Lebensmittelsicherheit, 2014Co-Authors: Laima Česonienė, Vilma Kraujalytė, Remigijus Daubaras, Petras Rimantas Venskutonis, Antanas ŠarkinasAbstract:The antimicrobial activities of fruit juices and ethanol extracts of Viburnum opulus L. genotypes were compared in this study. These activities were tested against human pathogenic microorganisms using the agar well diffusion method. A total of ten Gram-positive and Gram-negative bacterial cultures, as well as nine yeast strains, were used for the investigation. The most effective antibacterial activity was exhibited by the fruit juices against Salmonella typhimurium , Salmonella agona , and Listeria monocytogenes , with inhibition zones of 23.6, 20.7, and 19.1 mm, respectively. Staphylococcus epidermidis and Micrococcus luteus displayed the highest resistance, with minimal inhibition zones of 14.2 and 15.0 mm, respectively. The fruit juices showed greater antibacterial activity compared to the ethanol extracts. In contrast, the growth of the yeast cultures exhibited little or no sensitivity to the fruit juices and ethanol extracts. The conclusion of this study is that V. opulus fruits are potential antibacterial remedies.

Food Chemistry, 2013Co-Authors: Vilma Kraujalytė, Petras Rimantas Venskutonis, Laima Cesonienė, Audrius Pukalskas, Remigijus DaubarasAbstract:Antioxidant properties of fruit juices of six Viburnum opulus genotypes were evaluated by DPPH, ABTS(+) radical scavenging capacity (RSC), ferric reducing antioxidant power (FRAP), oxygen radical absorbance capacity (ORAC) and Folin-Ciocalteu total phenolic content (TPC) assays. TPC varied in the range of 5.4-10.6 mg gallic acid equivalents/g, RSC (ABTS(+)), FRAP and ORAC values were 31.9-109.8, 32.3-61.8 and 141.6-260.4 μmol trolox equivalents/g, respectively. V. opulus var. sargentii fruit juice was a remarkably stronger antioxidant than the other five V. opulus genotypes. The content of chlorogenic acid (the main phenolic compound in berry juices) depending on plant cultivar varied in the range of 0.54-6.93 mg/ml. The RSC of individual constituents was measured by the on-line HPLC-UV-DPPH method: chlorogenic acid was the dominant radical scavenger in V. opulus P3 (74%), while epicatechin and catechin (the main antioxidants in V. opulus var. sargentii) contributed to 40% and 23% of the total RSC for the sargentii genotype. Nine constituents were identified in V. opulus juice by using ultra high performance liquid chromatography coupled to quadruple and time-of-flight mass spectrometers (UPLC-QTOF-MS). In general, the study demonstrated that V. opulus var. sargentii followed by V. opulus P3 and V. opulus var. americanum possessed the highest antioxidant capacity. The obtained results may assist in selecting the most valuable V. opulus genotypes for the production of fruits possessing strong antioxidant capacity and containing beneficial phenolic constituents.

fruit removal in Viburnum opulus copious seed predation and sporadic massive seed dispersal in a temperate shrub
Oikos, 1993Co-Authors: Roger EnglundAbstract:The fruit removal in Viburnum opulus (Caprifoliaceae), an animal-dispersed shruh with fleshy fruits, was studied during two fruiting seasons in central Sweden. The fruit crops were ripe in September, but mainly removed during November-Decemher. Large infructescences were located in the upper part of shrubs and received the slowest removal rate. The removal agents were a diverse assemblage of seed predators and dispersers. At two field study-sites the most important removal agents were seed predators: bullfinches (Pyrrhula pyrrhula) (73% removal) and rodents, mainly bank voles (Clethrionomys glareolus) (26% removal). Fallow deer (Dama dama) infrequently contributed to fruit removal

Movement patterns of Cetonia beetles (Scarabaeidae) among flowering Viburnum opulus (Caprifoliaceae) : option for long-distance pollen dispersal in a temperate shrub
Oecologia, 1993Co-Authors: Roger EnglundAbstract:The movement patterns of flower-visiting Cetonia (Coleoptera, Scarabaeidae) were studied in central Sweden over 4 years, providing the first quantitative study of beetle pollination behaviour conducted in a temperate zone. The beetles were marked individually and tracked throughout their visits to Viburnum opulus L. (Caprifoliaceae), a partly beetle-pollinated shrub displaying large umbel-like, creamy-white blossoms. Beetle abundance differed greatly between study years. Of marked beetles observed on V. opulus flowers, an average of 26% returned each year. The beetles performed frequent inter-plant flights, and showed fidelity to particular V. opulus individuals at the study site. Furthermore, they preferred V. opulus to other plants flowering concomitantly and showed considerable constancy in this habit. Movements were mostly between individuals from unshaded locations with high inflorescence and flower number. Normally, the beetles flew on average about 4 times the horizontal nearest-neighbour distance between flowering V. opulus (c. 18 m). From these observations it is concluded that Cetonia beetles are powerful long-distance dispersal agents for V. opulus pollen, perhaps leading to an enhanced gene flow not possible with the plant's other pollinators.

Determination of the Total Phenolic and Anthocyanin Contents and Antimicrobial Activity of Viburnum opulus Fruit Juice
Plant Foods for Human Nutrition, 2012Co-Authors: Laima Česonienė, Remigijus Daubaras, Pranas Viskelis, Antanas ŠarkinasAbstract:Viburnum opulus is a plant with fruits that are rich in biologically active substances, making it valuable to the food and pharmaceutical industries. Here, we present our study of the total phenolic and anthocyanin contents and antimicrobial activity in the fruit juice of six V. opulus L. accessions. The cultivar ‘Krasnaya Grozd’ was notable for its exceptionally large amount of total phenolics, 1168 mg/100 g, with anthocyanins comprising 3–5 % of the total phenolic content. The evaluation of the antimicrobial properties confirmed that the juice of V. opulus fruits strongly inhibited the growth of a wide range of human pathogenic bacteria, both Gram-negative ( Salmonella typhimurium and S. agona ) and Gram-positive ( Staphylococcus aureus , Lysteria monocytogenes , and Enterococcus faecalis ) organisms. Conversely, the yeasts Debaryomyces hansenii and Torulaspora delbrueckii showed complete resistance to the fruit juice, whereas a low sensitivity was demonstrated by Trichosporon cutaneum, Kluyveromyces marxianus var. lactis , Saccharomyces cerevisiae , S. cerevisiae 12R, and Candida parapsilosis .

biochemical and agro biological diversity of Viburnum opulus genotypes
Central European Journal of Biology, 2010Co-Authors: Laima Cesonienė, Remigijus Daubaras, Jonė Venclovienė, Pranas ViskelisAbstract:Interest in the biochemical composition of Viburnum opulus fruit has intensified due to the food industry’s demand for natural vitamins, pigments and other substances that enhance the value of different foods. The present study was conducted to determine the agro-biological and biochemical variability of V. opulus and to select the genotypes that could best serve as sources of health promoting substances. Twelve selected genotypes were evaluated. ‘Leningradskaya Otbornaya’, V. opulus var. americanum, ‘Zarnitsa’, and local clone P2 were determined to be the best genotypes for growth in commercial plantations. Fruits of the local clone P3 were characterised by large amounts of total phenolics, ascorbic acid, and reducing sugars. V. opulus var. sargentii and V. opulus var. americanum contained exceptionally large amounts of total phenolics, 1460.0 and 1400.0 mg/100 g, respectively. The amount of ascorbic acid varied from 12.4 to 41.4 mg/100 g, the amount of carotenoids varied from 1.4 to 2.8 mg/100 g, the amount of anthocyanins varied from 23.2 to 44.6 mg/100 g, and the amount of total phenolics varied from 753.0 to 1460.0 mg/100 g. The presence of these large amounts of biologically active compounds enables their use as potent antioxidants. The data describing agro-biological characteristics, biochemical components, and health promoting activities of V. opulus fruits will increase the understanding of this plant and facilitate its use in the food and pharmaceuticals industry.
