The effects of 10 different extracts fruits and berries on cell proliferation colon cancer cells HT29 breast MCF-7 were investigated. used rosehips, blueberries, black currant, chokeberries, apple, sea buckthorn, plum, lingonberries, cherries, raspberries. decreased the both MCF-7, effect was concentration dependent. inhibition for highest varied 2−3-fold among species, it in ranges 46−74% (average = 62%) 24−68% 52%) cells. There great differences content analyzed antioxidants extracts....

The effects of extracts from five cultivars strawberries on the proliferation colon cancer cells HT29 and breast MCF-7 were investigated, possible correlations with levels several antioxidants analyzed. In addition, organic cultivation compared to conventional content in strawberry cell investigated. ratio ascorbate dehydroascorbate was significantly higher organically cultivated strawberries. decreased both a dose-dependent way. inhibitory effect for highest concentration range 41−63%...

Four cultivars of strawberries (Senga Sengana, BFr77111, Elsanta, and Honeoye) were studied for their content antioxidants, total antioxidant capacity, low molecular weight carbohydrates in relation to harvest year, ripening stage, cold storage. For ascorbic acid, chlorogenic ellagic antioxidative measured both water-soluble water-insoluble extracts, there was a 2−5-fold variation among cultivars. Unripe berries contained lower concentrations acid p-coumaric also quercetin kaempferol...

Abstract To investigate the variations in quality with growth stage and postharvest storage, spinach was sown on three occasions. For each occasion, harvested at stages 6‐day intervals. The second corresponded to a period used for baby by commercial growers. After harvest, leaves were stored polypropylene bags 2 °C or 10 °C. highest ascorbic acid content fresh material found I. During decreased considerably dehydroascorbic acid/vitamin C ratio increased. Storage gave smaller reduction than...

Abstract Bioactive compounds were investigated in genotypes (cauliflower 10, white cabbage curly kale 1) and plant parts of the three crops. The content most major glucosinolates glucobrassicin, sinigrin glucoiberin differed significantly between cultivars. Samples harvested 2000 had higher amounts several than samples from 1999. Within cauliflower buds floret 1.5 to 2.5‐fold concentration glucobrassicin 4‐methoxyglucobrassicin stalk. In their highest outer leaves (up 2‐fold higher). Upper...

Four cultivars of sea buckthorn berries were analyzed for their carotenoid and chlorophyll contents during ripening in three consecutive years. The different carotenoids generally increased concentration comprised from 120 to 1425 μg/g DW total (1.5−18.5 mg/100 g FW) depending on cultivar, harvest time, year. GLM analyses revealed the effect cultivar be considerably larger than that year time. content pheophytin a, a derivate, steadily decreased berry ripening. Pheophytin therefore acted as...

Variation in quercetin content was investigated field-cured onions (Allium cepa L.) that had been supplied with different nitrogen fertilizer levels and lifted at developmental stages. Quercetin varied significantly between years well correlated to global radiation August. Field curing generally resulted significant increases compared lifting. Nitrogen level did not affect content, suggesting leakage from soil may be minimized without effects on flavonol content. Lifting time minor onions....

The variation in flavonoid concentration and composition was investigated baby spinach (Spinacia oleracea L.) cv. Emilia sown on three occasions, each harvested at growth stages 6-day intervals. After harvest, leaves were stored polypropylene bags 2 or 10 degrees C. Flavonoids analyzed by reversed phase HPLC. Twelve peaks detected. main flavonoid, making up average 43% of the total concentration, identified as 5,3',4'-trihydroxy-3-methoxy-6:7-methylenedioxyflavone-4'-glucuronide. Four other...

Effects of heat treatment and storage on quercetin isorhamnetin content, major minor components isorhamnetin, glucosides aglycone, were investigated in onion (Allium cepa L.). The sweet 'Recorra' red onions 'Hyred' 'Red Baron' cultivated the south part Norway thereafter stored for eight months. either not field dried, but directly, or dried then stored, treated before storage. Neither nor caused any differences total flavonol content as well cultivars. two differed their changes during...

• Premise of the study : Storage oil (triacylglycerol) accumulates in tissues such as embryo and endosperm seeds fruit mesocarp, but seldom underground organs. As a rare exception, cultivated variants yellow nutsedge ( Cyperus esculentus ) contain high amounts both starch mature tubers. Methods Biochemical analyses light electron microscopy were used to accumulation patterns storage nutrients developing Key results During initial phase tuber development, conducting rhizome tissue is...

The influence of organic and conventional farming practices on the content single nutrients in plants is disputed scientific literature. Here, large-scale untargeted LC-MS-based metabolomics was used to compare composition white cabbage from agriculture, measuring 1,600 compounds. Cabbage sampled 2 years one two systems a rigidly controlled long-term field trial Denmark. Using Orthogonal Projection Latent Structures–Discriminant Analysis (OPLS-DA), we found that production system leaves...

Protein-based biostimulants (PBBs) are derived from the hydrolysis of protein-rich raw materials plant and/or animal origins, usually by-products or wastes agro-industries. The active ingredients (AIs) produced by have capacity to influence physiological and metabolic processes in plants, leading enhanced growth, nutrient water-use efficiency, tolerance abiotic biotic stresses, improved crop yield quality. This paper reviews state-of-the-art future opportunities for use PBBs, based on...

Sea buckthorn berries ( Hippophae rhamnoides L.) are used in foods, cosmetics, and pharmaceutical products. They of particular interest for their high content healthy phytochemicals, including vitamin E-related compounds (tocopherols tocotrienols). This study investigated the tocopherols tocotrienols during ripening from four cultivars sea over a three-year period. The results showed large variations depending on harvest date, cultivar, year. Levels alpha-tocopherol were higher early period,...

The effects of two nonchemical methods [controlled atmosphere (CA) storage and postharvest heating, alone or combined] on the quality (firmness, taste, color, skin wax) storability (losses resulting from bruising fungal decay) apples were investigated in a 3-year study. Fruits cultivars (cv. Aroma cv. Ingrid Marie) mechanically wounded opposing sides, inoculated with conidial suspensions one three pathogens [ Pezicula malicorticis (bull's eye rot), Penicillium expansum (blue mould),...

In this study, 33 spring and winter wheat genotypes were analyzed for carotenoid content composition. Investigated divided into four genotype groups i.e., spelt, landraces, old cultivars primitive wheat. The results showed a high level of variation among the in amount carotenoids grain with values (around 4 mg/Kg) especially one genotypes—Öland 8. Lutein was most common all investigated genotypes, contributing 70%–90% grain. Variation composition found not only but also between type,...

Human consumption of fruits and vegetables are generally below recommended levels. Waste from the production, e.g., un-used parts such as broccoli leaves stem when producing florets for food, is a sustainability issue. In this study, were analyzed content various dietary fibre phenolics, applying Uppsala method HPLC analyses, respectively. The results showed that had comparable levels (26%–32% dry weight (DW)) phenolic compounds (6.3–15.2 mg/g DW) to many other food considered valuable in...
