Research of chemical composition of cloudberry fruit

Rubus chamaemorus L. commonly known as cloudberry is a widespread plant of the northern latitudes which had been used in folk medicine of these countries as a source of vitamins. The aim of this work was to research the bioactive compounds of cloudberry fruit gathered in fruitage. The qualitative composition and quantitative content of chemical compounds were determined by TLC, spectrophotometry and chromatography-mass spectrometry by using standard samples. Essential oil was gotten by micro steam distillation/solvent extraction (SD/SE). The trace element composition of investigated species was established by means of inductively coupled plasma mass-spectroscopy. As a result of the given research, a presence of some vitamins (ascorbic acid, carotenoids, phylloquinone, retinol, tocopherol) has been established the structure of bioactive compounds of cloudberry fruit. The quantitative content of some compounds has also been defined as follows: ascorbic acid –240mg%, β- carotene –2.5mg%, rutin –6.7%, water-soluble polysaccharides and pectin –6.5%, essential oil –0.05%. Additionally it was established a great content of potassium ˜ 15.0mg/g and unbound organic acids, which were determined as follows: citric, tartaric, oxalic and malic acids. The total content of acids was defined ˜ 5.0%. Cloudberry fruit can is an excellent source of polyvitamins and microelements.
