The paper presents results of the complex research of different species of Fagopyrum (F. esculentum Moench, F. tataricum (L.) Gaertn., F. cymosum Meissn.) on rutin content and their usage prospects as a resource of flavonoids. Relation between rutin content in the overground mass and the plant colour was found. Biological significance of rutin, prospects of its usage as a diagnostic trait in selection, are also shown in the article. Bio-chemical and technological traits of F. esculentum varieties cultivated in the Far East Russia were also studied and reflected in the paper. We therefore examined rutin content in the overground phytomass of the three species of Fagopyrum on the phase of mass flowering and discovered that high indices belong to: F. esculentum (Izumrud variety) ‒ 3.8 %, F. tataricum (sample k-62 from Canada) ‒ 4.4 % and F. cymosum (k-4231 from India) ‒ 4.1 %.  Rutin content in the hull of common buckwheat ranged from 0.08 till 0.20 %. Maximum rutin quantity was determined in the hull of Ussurochka (35.7 kg/ha), and minimum (17.8 kg/ha) in the hull of Pri 7. The studies show that the ash content, obtained after burning the hull of F. esculentum (600°C) is in average 2 %. The following elements were found in the ash: potassium, sodium, copper, silver, calcium, magnesium, zinc, aluminum, manganese, iron, nickel, chromium, phosphorus, and their concentration depend on variety and type of raw material of F. esculentum. Key words: Fagopyrum esculentum, F. tataricum, F. cymosum, overground mass, hull, rutin   Izvleček V prispevku so predstavljeni rezultati kompleksne raziskave različnih vrst rodu Fagopyrum (F. esculentum Moench, F. tataricum (L.) Gaertn., F. cymosum Meissn.) o vsebnosti rutina in možnosti njihove uporabe kot vira flavonoidov. Ugotovljeno je bilo razmerje med vsebnostjo rutina v nadzemni masi in barvo rastlin. V članku je prikazan tudi biološki pomen rutina, možnosti njegove diagnostične uporabe pri selekciji oziroma njegov pomen pri selekciji. V delu so bile proučene tudi biokemijske in tehnološke lastnosti sort F. esculentum, ki jih gojijo na Daljnem vzhodu Rusije. Zato smo določali vsebnost rutina v nadzemnih delih treh vrst rodu Fagopyrum v fazi cvetenja in ugotovili, da visoki indeksi pripadajo: F. esculentum (sorta Izumrud) ‒ 3,8 %, F. tataricum (vzorec k-62 iz Kanade) ‒ 4,4 % in F. cymosum (k-4231 iz Indije) ‒ 4,1 %. Vsebnost rutina v luščinah navadne ajde je znašala od 0,08 do 0,20 %. Največja količina rutina je bila določena v luščinah Ussurochka (35,7 kg/ha) in najmanjša (17,8 kg/ha) v luščinah Pri 7. Študije kažejo, da je vsebnost pepela, pridobljenega po upopelnjenju luščin F. esculentum (600°C), v povprečju 2 %. V pepelu so bili določeni naslednji elementi: kalij, natrij, baker, srebro, kalcij, magnezij, cink, aluminij, mangan, železo, nikelj, krom, fosfor, njihova koncentracija pa je odvisna od sorte in rastlinskega dela vrste F. esculentum. Ključne besede: Fagopyrum esculentum, F. tataricum, F. cymosum, nadzemna masa, luščine, rutin

The research results of technogenic objects in the Far East of Russia, in particular, the silt of the settling pond "Chalgany" and the waste of the Chalganov kaolin plant are given. The presence of valuable components in the investigated objects is shown, in particular: gold, noble metals, rare earth elements. It is established that gold in the investigated objects is represented mainly by a difficult-to-extract finely dispersed class of fineness (<5 μm). The methods of preliminary concentration and hydrometallurgical processing, which allow extracting gold from the studied technogenic objects, are proposed. The effectiveness of noncyanide methods of ammonia-thiosulphate and thiocarbamide leaching was investigated. It is shown, that the efficiency of gold recovery from the silt of the settling pond “Chalgany” by the thiocarbamide method reaches 93.5%. It is established that the waste from the Chalganovskiy kaolin plant, after recovering the concentrate of precious metals from them, can serve as a raw material for the production of chemically pure silicon and silica, as well as aluminum, its compounds, and refractory fibrous materials.

Technology of milt preserve is developed for marine fish caught in the Far East of Russia. The milt is a perspective raw material possessing high food and biological value. Its ability for preserving is determined, indicators of preserving and organoleptic properties of finished product are investigated. The presented technology expands food assortment and provides rational utilization of fish raw materials.
