“…The differences between the two cultivation methods were significant at days 7 and 10 (t-test: p = 0.002 and 0.0005, respectively). The content of fagopyrin in 14-day-old buckwheat sprouts grown in the sprouter was nearly the same as that reported for mature plants (11,13), but the content of polyphenols was only approximately 20 to 30 % of mature plants. All the contents are expressed per sprout dry mass.…”

“…The fagopyrin content was determined by a spectrophotometric method, as described in our previous study (13). This method was found to give slightly higher results compared to the recently developed HPLC method (11).…”

“…Our previous studies and other studies showed that leaves of common buckwheat contain 0.4 to 0.6 mg g -1 dry mass, stems 0.04 to 0.12 mg g -1 dry mass and flowers 0.64 mg g -1 dry mass of fagopyrin. No fagopyrin was detected in buckwheat groats and the hulls contain only 0.02 mg g -1 dry mass (11,13).…”

Dried buckwheat herb is used in medicinal products whereas fresh green plant parts, especially sprouts, are consumed as a vegetable. The herb contains fagopyrins, which cause sensitivity to light after ingestion. The aim of this study was to investigate the impact of different growing conditions and the development phase on the content of fagopyrin and phenolic compounds in buckwheat sprouts. Total flavonoid and total phenol contents, fagopyrin content and antioxidant activity were determined spectrophotometrically. Fagopyrin and flavonoids were located almost exclusively in cotyledons. Based on a comparison to hypericin toxicity, the recommendable intake of buckwheat sprouts was estimated to be less than 40 g per day.

“…Increased ETS activity indicates that plants are under stress. When the stress is too strong and plants cannot cope with it any more, the respiratory potential drops (Ožbolt et al, 2008), as shown in Figure 1. However, potential photochemical efficiency of PSII in soybean was close to 0.8 in Se treated and untreated plants.…”

Effect of selenium (Se) was studied in soybean (Glycine max (L.) Merr.) cv. Olna in Ljubljana, Slovenia. Se was added to plants as foliary spraying. Quantum yield of photosystem II (PSII) and respiratory potential measured as ETS activity of mitochondria were measured two times in the growing season. Respiratory potential was higher in young plants compared to mature plants. Se induced the lowering of respiratory potential. Addition of Se had no effect on quantum yield of photosystem II.

“…3 Fresh green plant parts containing UV-B absorbing compounds are used as an antioxidant-rich vegetable or dried for herb-tea. [4][5][6] Buckwheat can be used for a wide range of food products, and being without gluten is appropriate for celiac disease patients. It has antioxidant, anti-inflammatory and anticancerogenic effects, and can reduce the fragility of blood vessels.…”
