| characterization of gamma-linolenic acid in ribes seed. | the total lipid content of fruit seeds of the ribes family ranges by weight from 18.3% in goose-berries (ribes uva crispa) to 30.5% in black currants (ribes nigrum). isolation procedures and analytical methods (gas chromatography, mass spectrometry, high performance thin layer chromatography and stereospecific analysis) demonstrate that the oils from ribes seeds contain up to 19% by weight of gamma-linolenic acid (gamma-la, c18:3, n-6) in black currant oil. this last ribes species thus constitut ... | 1984 | 6098796 |
| berry fruits: compositional elements, biochemical activities, and the impact of their intake on human health, performance, and disease. | an overwhelming body of research has now firmly established that the dietary intake of berry fruits has a positive and profound impact on human health, performance, and disease. berry fruits, which are commercially cultivated and commonly consumed in fresh and processed forms in north america, include blackberry ( rubus spp.), black raspberry ( rubus occidentalis), blueberry ( vaccinium corymbosum), cranberry (i.e., the american cranberry, vaccinium macrocarpon, distinct from the european cranbe ... | 2008 | 18211023 |
| use of potassium bicarbonate (armicarb) on the control of powdery mildew (sphaerotheca mors-uvae) of gooseberry (ribes uva-crispa). | powdery mildew (sphaerotheca mors-uvae) severely infects young shoots, stems and fruits of gooseberry (ribes uva-crispa). environmental friendly and biological control measures are being sought throughout the world. especially in organic gooseberry growing effective control measures are needed, because powdery mildew infections may result in a total loss of the crop. in organic currant growing the number of adequate control methods is very limited. sulphur as a fungicide against powdery mildew i ... | 2010 | 21534463 |
| carbon relations and competition between woody species in a central european hedgerow : i. photosynthetic characteristics. | the co2 uptake capacity of leaves of five competing woody species in an undisturbed developing central european hedgerow was investigated for possible factors determining competitive ability in the field. light-saturated maximal co2 uptake (a max) showed species-specific seasonal variations in prunus spinosa, a bushlike pioneer on fallow land, in crataegusxmacrocarpa and acer campestre, two treelike species dominating the canopy, in rubus corylifolius, a pioneer liane, and in ribes uva-crispa, a ... | 1984 | 28311448 |
| evaluation of polyphenolic profile and nutritional value of non-traditional fruit species in the czech republic--a comparative study. | dry matter, organic acids, ascorbic acid, minerals (nitrogen, phosphorus, potassium, calcium, magnesium, sodium) and polyphenolic profile of a number of non-traditional fruit species and their genotypes, namely blue honeysuckle (lonicera spp.), saskatoon berry (amelanchier alnifolia), black mulberry (morus nigra), tomentosa cherry (prunus tomentosa thunb.) and jostaberry (ribes nigrum x grossularia uva-crispa) were investigated. the results showed that lonicera genotypes displayed high levels of ... | 2012 | 22842642 |
| biology, early stages and description of a new species of adelognathus holmgren (hymenoptera: ichneumonidae: adelognathinae). | adelognathus leucotrochi shaw & wahl sp. nov. is described from britain where it is a univoltine slightly gregarious koinobiont ectoparasitoid of late stage larvae of the tenthredinid sawfly nematus leucotrochus hartig feeding on ribes uva-crispa. defensive reactions by the host to prospecting females are described. the developmental biology of a. leucotrochi is described in detail: the host is only temporarily paralysed by the injection of a venom that has no other effect on the host, and eggs ... | 2014 | 25543782 |
| analysis and sensory evaluation of jostaberry (ribes x nidigrolaria bauer) volatiles. | volatiles of jostaberries (ribes x nidigrolaria bauer)--a hybrid of black currant (ribes nigrum l.) and gooseberry (ribes uva-crispa l.)--were isolated via vacuum headspace extraction and analyzed by capillary gas chromatographic methods for the first time. (e)-hex-2-enal, (e)-hex-2-en-1-ol, (z)-hex-3-enal, (z)-hex-3-en-1-ol, methyl butanoate, ethyl butanoate, 2-methylbut-3-en-2-ol, and 1,8-cineol turned out to be the most dominant volatiles. the variability of the volatile profile was shown by ... | 2013 | 23991667 |
| a high-throughput monolithic hplc method for rapid vitamin c phenotyping of berry fruit. | a rapid method for the quantification of l-ascorbic acid (1) in berry fruit by hplc with photodiode array detection is presented. l-ascorbic acid was resolved on a c18 monolithic column with aqueous buffer, after which the column was washed with acetonitrile to remove lipophilic compounds prior to re-equilibration for analysis of the next sample. using the monolithic column format with high mobile phase flow rates, the entire separation, wash and re-equilibration were achieved in 3 min. with the ... | 2017 | 17019929 |
| characterization of anthocyanins and proanthocyanidins in some cultivars of ribes, aronia, and sambucus and their antioxidant capacity. | anthocyanins and proanthocyanidins were characterized by hplc-esi-ms/ms coupled with a diode array and/or fluorescent detector in seven cultivars of ribes nigrum (black currant) and ribes rubrum (red currant, red lake), six cultivars of ribes grossularia (gooseberries), aronia melanocarpa(chokeberry), and sambucus nigra (elderberry). thirty-one different anthocyanins were detected in these berries, but not every anthocyanin was observed in each berry. a number of minor anthocyanins were identifi ... | 2004 | 15612766 |
| quality assessment of low-sugar jams enriched with plant raw materials exhibiting health-promoting properties. | low-sugar gooseberry jams enriched by the addition of black chokeberry, elderberry, japanese quince, flax seeds and wheat germs were examined for the content of total polyphenols, total flavonoids, and total anthocyanins as well as their antioxidant activity (dpph, abts, and frap) and individual phenolic compounds. the jams were evaluated immediately after production and after 6 and 12 months of storage. samples were stored at chilled temperature (10 °c) and room temperature (20 °c). a significa ... | 2018 | 29358834 |
| mechanisms of macroevolution: polyphagous plasticity in butterfly larvae revealed by rna-seq. | transcriptome studies of insect herbivory are still rare, yet studies in model systems have uncovered patterns of transcript regulation that appear to provide insights into how insect herbivores attain polyphagy, such as a general increase in expression breadth and regulation of ribosomal, digestion- and detoxification-related genes. we investigated the potential generality of these emerging patterns, in the swedish comma, polygonia c-album, which is a polyphagous, widely-distributed butterfly. ... | 2013 | 23952264 |
| analysis and sensory evaluation of gooseberry (ribes uva crispa l.) volatiles. | volatiles of gooseberries (ribes uva cripsa l.) were isolated by means of vacuum-headspace-extraction, and the obtained concentrates were analyzed via capillary gas chromatography-mass spectrometry. to ensure the quantitation of highly volatile compounds, headspace analysis was additionally performed on selected batches. c₆-components (e.g., (z)-hex-3-enal, (e)-hex-2-enal), derived from lipid oxidation, and short-chain esters (e.g., ethyl acetate, methyl butanoate, ethyl butanoate) turned out to ... | 2013 | 23721163 |
