Seeds of hypericum perforatum l. – Perspective edible oil raw material

Hypericum perforatum introduced into cultivation long ago. If reserve stock of its seeds didn´t use they can be used for other purposes, such as perspective medicinal row material. Extractive substances from seeds of Hypericum perforatum (reproduction of All-Russian Institute of Medicinal and Aromatic Plants) have been sequentially extracted with n-hexane (lipid complex containing edible oil rich in poluunsaturated acids in an amount about 35,0%); extracted with 95% ethanol (in an amount about 20,0%) and with purified water (in an amount about 2,5%). An amorphous material with about 0,7% amount was isolated from lipid fraction. It is insolubled in acetone. Calculations are given in air-dry raw material. Experiments repeating is triple.1H NMR spectroscopy was used for the preliminary study of the composition of triacylglycerols (TAG) in edible oil. Content of ά-linoleic acid in the lipid complex is 30%. An analogue of iodine number is 168. The refractive index is 1,4752 ± 0,001. Qualitative analysis showed that the aqueous extract of the shrot after extraction and alcohol-lipid complexes is presented flavonoids and condensed tannins. Dispersed composition of the seeds is also studied. 86,4% of the seeds of Hypericum perforatum has size of less than 0,5 mm. Morphological features and some technological properties of seeds of Hypericum perforatum also have been revealed. Seeds of Hypericum perforatum could be interesting as a new type of raw material for essential edible oil.
