[The fatty acid composition of ordinary flax seed oil (Linum usitatissimum L.) cultivated in Georgia and its byological activity].

The aim of the study was individual quantitatively and qualitatively determination of fatty acids in ordinary flax seed oil (Linum usitatissimum L.), cultivated in Georgia. The neutral lipids extracts were fractionated and analyzed by high performance liquid chromatography (PTC-1, Waters) with refractory detector R-401. Analitical column (150,0x3,0 mm) was filled with reversphase Bondopak C18). Software OASIS-740 is used. The correction retention times of each fatty acids is compared with comformity standard. The investigation showed that in flax seed oil linoleic (31,3±2,1 mg%) and linolenic (40,2±2,9 mg%) acids were predominant and together constitute principal basic of research composition. The flax seed oil contained also palmitic and stearic acids in less quantitaty.

[The fatty acid composition of Ruta graveolens seed oil and its byological activity].

Using high-performance liquid chromatography methods are qualitatively and quantitatively identified most biological important high fatty acids, contained in Ruta graveolens seed oil grown on the experimental plot of Kutateladze Institute of Pharmakochemistry (Georgia) and compare its biological activity. Their relative concentration is expressed as percentages of the total fatty acid component. The sample contained the range of fatty acids from С12:0 to С22:0. The investigation showed different sensitivity of components. In order of elution the list of compound are reported. The oil contained 2,08±0,1 mg% lauric, 2,18±0,1 mg% miristic, 3,98±0,1 mg% palmitic, 30,90±1,2 mg% stearic, 41,92±1,8 mg% oleic, 10,14±0,4 mg% linolic, 6,50±0,3 mg% linolenic, 2,00±0,1 mg% arachinic and 2,10±0,1 mg% begenic acid. The chromatography signals with retention values 7,96 and 14,08 minuts are qualitatively not identified.

[The fatty acid composition of peach oil and its biological activity].

Using high-performance liquid chromatography methods (Cromatograph PTC-1, repractometer R-401, column Bondopaс C18) were quantitatively and qualitatively identified most biological important high fatty acids, contained in peach oil (Persica Vulgaris) from ost region of Georgia (Kacheti). Their relative concentrations are expressed as percentages of the total fatty acids components. The chromatography investigation shaved, that the oil contained 12,98±1,0mg% linoleic, 9,97±0,3 mg% palmitic, 4,82±0,2 mg% linolenic, 3,58±0,1 mg% begenic and 2,16±0,1 mg% arachinic acids. The predominant fatty acids of peach oil were linoleic, palmitic and oleinic acids. The investigation showed different sensitivity of components contained in peach oil.

[Fatty acid of Rkatsiteli grape seed oil, Phellodendron lavallei oil and Amaranthus seeds oil and its comparative byological activity].

The aim of the study is individual qualitively and quantitatively identification of fatty acids in Pkatsiteli grape seed oil, Phellodendron lavallei oil and Amaranthus seed oil and prediction of its biological activity. Using high-effective liquid chromatogramphy fatty acids were franctionated. Their relative concentrations are expressed as percentages of the total fatty acid component. Identification of the fatty acids consituents is based on comparison of their retention time with that of known standards. The predominant fatty acids in the oils were palmitic, oleic and stearic acids. The investigation demonstrated that fatty acids composition takes marked part in lipid metabolism of biological necessary components. The most interesting result of the investigation was the detection of unusual for the essentain oil begenic acid.

[Elimination of haloperidol from erythrocytes surfaces supernatant and blood plasma].

The aim of the study was to investigate the adsorption rate of haloperidol on erythrocytes surfaces. The pharmacokinetic and pharmacodynamic parameters of haloperidol were monitored in the experiment. The neuroleptic was administered to 12 adult dogs and the blood samples were collected for further analysis following 20, 30, 60, 180, 240, 360, 420 and 480 minutes after the injection. The groups of samples (blood plasma and supernatant) were monitored during this period. The differences between haloperidol concentration in the supernatant and blood plasma were compared. Our data have shown that dynamics of the elimination of intact and acidified forms of haloperidol from the supernatant and the blood serum are not the same. Intact and acidified forms are differently regulated by plasma. albumines and globulines. The process of redistribution of haloperidol between the both substrates takes place, while the supernatant has a donor function for the free form of haloperidol and represents the acceptor of the haloperidol's metabolites. This provides the possibility to develop multidiscipline approach to the optimization to the prescription of haloperidol.
