Postharvest Biology and Technology > 2015 > 110 > Complete > 173-182

Apple fruit contains a wide range of chemical compounds that may contribute to resistance against blue mold caused by Penicillium expansum. In the present study, contents of total titratable acidity, malic acid, total phenols and 10 individual phenolic compounds were quantified in peel and flesh fractions of both control and blue mold-inoculated fruits of 24 apple cultivars. In addition to the significant...

Major phenolic compounds in black currant (Ribes nigrum L.) buds: Variation due to genotype, ontogenetic stage and location

Michael Vagiri, Anders Ekholm, Eva Johansson, Staffan C. Andersson, more

LWT - Food Science and Technology > 2015 > 63 > 2 > 1274-1280

Black currant buds are rich in phenolic compounds and are used as raw material in the food and health industry. The variation in content of major phenolic compounds due to genotype, ontogenetic stage, location and season were studied in buds of five genotypes over three years at two widely separated locations in Sweden. Regression analyses revealed the effect of season to be considerably larger than...

Food Chemistry > 2015 > 172 > Complete > 135-142

Blackcurrant leaves are an essential source of phenolic compounds and this study investigated their variation relative to leaf positions and harvest date. The phenolic content varied between harvest dates, although leaf position on the shoot and interactions also played an important role. The contents of quercetin-malonyl-glucoside, kaempferol-malonyl-glucoside isomer and kaempferol-malonyl-glucoside...

Tocopherols in rose hips (Rosa spp.) during ripening

Staffan C Andersson, Marie E Olsson, Karl‐Erik Gustavsson, Eva Johansson, more

Journal of the Science of Food and Agriculture > 92 > 10 > 2116 - 2121

BACKGROUND: Rose hips are used as a food ingredient and in health products. They are rich in various bioactive compounds such as carotenoids and vitamin C, but data on their vitamin E content (tocopherols and tocotrienols) are limited. In this study, four different species ofRosa were analysed for tocopherol and tocotrienol content during ripening in three different years. RESULTS: Only α‐ and γ‐tocopherol...

Scientia Horticulturae > 2012 > 136 > Complete > 9-16

Leaves of Plantago major L. (common plantain) have been used for centuries almost all over the world as a wound healing remedy, and for other medicinal purposes. Polyphenols have been proposed to be responsible for many of the medicinal properties attributed to P. major. In this study, plants from 19 subpopulations (offspring families), derived from a total of five populations of P. major collected...

Carotenoid content and composition in rose hips (Rosa spp.) during ripening, determination of suitable maturity marker and implications for health promoting food products

Staffan C. Andersson, Kimmo Rumpunen, Eva Johansson, Marie E. Olsson

Food Chemistry > 2011 > 128 > 3 > 689-696

Carotenoids are important antioxidants and valuable bioactive compounds contributing to the health benefits of different foods, and rose hips are known for high bioactive content. This study investigated the content of carotenoids and chlorophylls in hips from four rose species during the ripening period. Carotenoid content varied greatly between harvesting times, although species and year, and interactions...

Analysis of carbonyl compounds in sea buckthorn for the evaluation of triglyceride oxidation, by enzymatic hydrolysis and derivatisation methodology

Sindhu Mathew, Carl Grey, Kimmo Rumpunen, Patrick Adlercreutz

Food Chemistry > 2011 > 126 > 3 > 1399-1405

Carbonyl compounds formed in sea buckthorn berry (Hippophae rhamnoides) and oil samples as a result of lipid oxidation were determined by enzymatic hydrolysis followed by derivatisation with 2,4-dinitrophenylhydrazine and analysed by LC–UV and electrospray ionisation (ESI) tandem mass spectrometry (MS/MS). Several classes of carbonyl compounds such as saturated, unsaturated, linear and branched aldehydes...

Major polyphenols in aerial organs of greater plantain (Plantago major L.), and effects of drying temperature on polyphenol contents in the leaves

Muhammad Zubair, Hilde Nybom, Christina Lindholm, Kimmo Rumpunen

Scientia Horticulturae > 2011 > 128 > 4 > 523-529

Plantago major L. (common plantain) has been used in folk medicine all over the world, mainly for the healing of wounds. This species already has a high market demand in Asia, and attempts to domesticate P. major as a medicinal crop in horticulture are emerging also in Europe. Both polysaccharides and polyphenols have been proposed to have bioactive effects. In this study, major phenols were analysed...

Antiproliferative effects of sea buckthorn (Hippophae rhamnoides L.) extracts on human colon and liver cancer cell lines

Carl Grey, Cecilia Widén, Patrick Adlercreutz, Kimmo Rumpunen, more

Food Chemistry > 2010 > 120 > 4 > 1004-1010

Sea buckthorn berries contain many bioactive compounds that have anticancer properties. To investigate whether the antiproliferative effects could be associated with the presence of certain compounds, a sequential extraction was performed. The extraction started with heptane followed by ethyl acetate, ethanol, and water. A second protocol using ethanol:water (1:1) was also used. The contents of the...

Scientia Horticulturae > 2002 > 96 > 1-4 > 351-357

Microshoots and softwood stem cuttings of five clematis varieties (Clematis section Atragene) were rooted in different substrates (perlite, peat-perlite, and sand-perlite). Microshoots rooted better and quicker than stem cuttings, independent of the substrate. Root dry mass of microshoots was more than twice as high compared to root dry mass of stem cuttings.For microshoots, number of primary roots...

Edite Kaufmane, Kimmo Rumpunen

Scientia Horticulturae > 2002 > 94 > 3-4 > 241-249

Micro- and macrosporogenesis as well as the male and female gametophyte development were studied in Chaenomeles japonica (Japanese quince). The archesporium of the microsporogenesis was already recognised in November. The development was arrested during winter and was not resumed until March the following spring. The process followed the normal route and resulted in binucleate pollen. One deviating...

Pollination, pollen tube growth and fertilization in Chaenomeles japonica (Japanese quince)

Edite Kaufmane, Kimmo Rumpunen

Scientia Horticulturae > 2002 > 94 > 3-4 > 257-271

The fertilization system in Japanese quince, Chaenomeles japonica (Thunb.) Lindl. (Maloideae, Rosaceae) was studied by fluorescence microscopy. In a compatible combination, pollen grains germinated fast and pollen tubes grew rapidly, through the stylar tissue. Most of pollen tubes reached the base of the ovary within 2-6 days. In the ovary, pollen tube growth was considerably retarded, and fertilization...
