Selenium fertilization alters the chemical composition and antioxidant constituents of tomato (Solanum lycopersicon L.).

Vegetative growth and chemical composition of tomato plants as affected by different types of salt stress and zinc fertilization

New solanocapsine-type tomato glycoside from ripe fruit of Solanum lycopersicum.

A new solanocapsine-type tomato glycoside, a novel and interesting natural steroidal glycoside, was isolated from a mini tomato, Solanum lycopersicum L. The chemical structure of the new minor glycoside, esculeoside B-5 (3), was determined to be (5S,22R,23S,24R,25S)-22,26-epimino-16β,23-epoxy-3β,23,24-trihydroxycholestane 3-O-β-lycotetraoside.

Nutritional composition and antioxidant activity of four tomato (Lycopersicon esculentum L.) farmer' varieties in Northeastern Portugal homegardens.

The nutritional and antioxidant composition of four tomato Portuguese farmer' varieties widely cultivated in homegardens was determined. The analysed components included macronutrients, individual profiles of sugars and fatty acids by chromatographic techniques, hydrophilic antioxidants such as vitamin C, phenolics, flavonols and anthocyanins, and lipophilic antioxidants such as tocopherols, β-...

Sterol composition of tomato (Solanum lycopersicum L.) seed oil: the effect of cultivar

The effect of cultivar on sterol composition of tomato (Solanum lycopersicum L.) seed oil from three industrial cultivars (Principe Borghese, Rebelion F1 and San Marzano) grown in Calabria Region (Southern Italy) was investigated. Sterol composition is presented both as percentage on the total sterol content (%) and as an absolute value (mg/kg). Rebelion F1 produced the worst seed oil in terms ...

Effect of Organic Fertilizer and Irrigation Intervals on the Yield and Quality of Cherry Tomato (Solanum lycopersicon var. cerasiforme)

To investigate the effects of organic fertilizers and irrigation frequencies on yield and quality of cherry tomato an experiment was conducted using six fertilizer doses including control (no fertilizer), NPK fertilizer (urea at 300 kg, TSP 200 kg and MoP 250 kg), cow-dung at 5 t ha-1, cow-dung at 10 t ha-1, poultry manure at 5 t ha-1 and poultry manure at 10 t ha-1 with two levels of irrigatio...
