The results of sea buckthorn fruits biochemical analysis in natural and artificial Tyva phytocenoses are presented. The dependence of the oil, vitamin C, carotinoids, sugars and acids content from the fruit development phase and moisture conditions is demonstrated. Sea buckthorn fruits from the natural phytocenoses differed high (5.5%) oil content in the phase of maturation, as in flooded areas as well without flooding. In fruits from the artificial phytocenoses at 5-6% less oil appeared than in natural cenoses. The vitamin C and carotenoids content in fruits of sea buckthorn was high, both in natural and artificial phytocenoses. With a view to maximum vitamins harvesting fruits should be collected at different periods: vitamin C - fruits growth phase and on carotenoids - a maturation phase, as flooded (irrigation) areas both with and without glaze. For sweet fruits with lower acid content, they should be harvested at the stage of maturation, preferring bushes with large fruits (8 mm or more) with regular watering or in flooded areas. The maximum content of carotenoids in both the natural and the artificial in phytocenoses was found in fruit ripening phase. The sugar content of sea buckthorn fruit was significantly (1.5 - 2.2 times) below and acids content, conversely, was (in 1.2 to 1.5 times) higher in natural in phytocenoses than in the artificial ones.
