The aim of the study was comparing the chemical composition of the essential oils from five varieties of lavender (Lavandula angustifolia L.) and their antibacterial activity. The flower spikes of different varieties of lavender comprised the material for the tests (Lavandula angustifolia): "Munstead", "Munstead Strain", "Blue River", "Ellegance Purple" and "Lavender Lady". The dried material parts (20 g) were submitted to hydrodistillation for 3 hours using Deryng's type apparatus, according to the European Pharmacopoeia. The oil was stored at 4 °C until the GC-MS analysis. The oils were assayed against three bacterial, Staphylococcus aureus, Pseudmonas aeruginosa and Escherichia coli. Evaluation of antimicrobial activity in vitro of the essential oil was performed with the use of the disc — diffusion method. 18 Hour cultivation of a particular strain of bacteria in liquid medium was diluted with physiological NaCl solution to a density of 0.5 McFarland. Obtained in this way, a bacterial suspension was applied evenly over the entire plate surface to a solid Mueller-Hinton II (Oxoid), using a sterile swab sticks. Paper disks (diameter

6 mm) were soaked with 10 ^l of a particular essential oil and were immediately applied symmetrically on the inoculated plate. Plates were incubated for 24 h at 37 °C and next zones of inhibition were measured. The primary components of the analyzed essential oils were: linalool (23,9-15,8 %), linalyl anthranilate (12,3-1,6 %>), 1-terpinen-4-ol (9,7-5,5 %>), p-menth1--en-8-ol (7,9-4,0 %>), linalool oxide (4,7-1,1 %>). Moreover, we observed a difference in some compounds, existing in low concentrations that may influence the biological properties. From the essential oils that were tested, the "Blue River" variety have the greatest antibacterial activity. The highest increase of Staphylococcus aureus as well as Pseudomonas aeruginosa and Escherichia coli bacteria was inhibited by the activity of the essential oils from the "Blue River" variety. Medium zones of inhibition for "Blue River" are as follows: 19.5 mm on Staphylococcus aureus (reference strain), 18.2 mm on Staphylococcus aureus (strain isolated from skin MRSA/ORSA), 10.0 mm on Pseudomonas aeruginosa (strain isolated from skin) and 19.9 mm on Escherichia coli (reference strain).

The original antitumor preparation "Arglabin", antiathero-sclerotic drug "Aterolid", hepatoprotector "Salsocollin», adaptogenic preparation «Ecdyphyt» and antiparasitic drug «Sausalin» were developed in holding «Phytochemistry» and introduced in clinic. They were developed on the basis of biologically active compounds of endemic species. Preparation «Arglabin» was tested on over 3000 oncological patients for the period 2000-2010 in the oncological centers of the far abroad and the Commonwealth of Independent States. Thus, the clinical efficiency of preparation was 76 %. Preparation «Arglabin» with mechanism action belongs to targeted preparations, i. e. there is not direct action on tumor cell, and on transfer path of tumor signal, namely, inhibits synthesis of farnesiltransferase. Results of I and II phases of the clinical tests of preparation «Aterolid» as hypolipidemic agent showed efficiency at treatment of 200 patients with dislocoproteinemia and atherosclerosis. «Aterolid»

reduces a level of cholesterol, triglycerides and general lipids and improves a level of lipoproteins with high density more effectively than comparison preparation «Pravastatin». The clinical efficiency of hepatoprotec-tive drug "Salsocollin» on 410 patients with chronic virus, alcoholic, toxic hepatitis, liver cirrhosis of various etiology, biliary dyskinesia and chronic noncalculous cholecystitis was proved. The cost price of course treatment with "Salsocollin» is below than widely applied preparation «Essentiale-forte». The clinical efficiency of adaptogenic preparation «Ecdyphyt» was proved at complex treatment on 450 patients with pulmonary tuberculosis. «Ecdyphyt» is well tolerated by patients, not toxic in practice, have not the expressed by-effects peculiar to anabolic steroids of testosterone row and does not influence on functionalities of adrenal cortex. The full sanitation at treatment with preparation «Sausalin» was determined by results of two phases of the clinical tri-

als on 392 patients with verified diagnoses of lambliasis and opisthorchiasis. Thus, it testifies about its antiparasitic activity. The Karaganda pharmaceutical complex was constructed and put into operation on the basis of

holding «Phytochemistry». The complex has capacity of 2 millions ampoules, 150 millions tablets, capsules and 2 millions soft dosage forms of original competitive phy-topreparations.

Attempts to restore cholinergic function have been considered as a rational target to improve the symptoms of Alzheimer's disease. One therapeutic option is the use of AChE inhibitors which block this key enzyme in the breakdown of acetylcholine (1). During the last decade the use of herbal medicinal preprations in dementia therapy has been studied based on traditional medicine (2). Gum ammoniacum is a gum-resin from Dorema am-moniacum D. Don which has been used in Unani and iranian traditional medicine for several indications. A previous study showed AChE inhibitory activity for a dichlo-romethane extract of this resin (3). The aim of this study was the isolation and characterization of active compounds from gum ammoniacum. Extraction of the resin was performed by sonification with dichloromethane. The extract was investigated by a respective colorimet-ric microplate assay and the active zones were identified via TLC bioautography. Then the active compounds

were isolated using several chromatographic techniques such as vacuum liquid chromatography, column chromatography and counter current chromatography. The structures of the active components were characterized by different methods such as one and two-dimension-al1H and13C NMR spectroscopy (COSY, TOCSY, HSQC, HMBC, NOESY) and mass spectrometry. Two spiro-sesquiterpenoidic chromadiones were characterized as active components and one of them is a new compound. Their iC50 values for AChE inhibitory activity were determined by microplate assay as 77 and 100 ^g/ml. The extract was analyzed by HPLC to determine the concentration of active compounds in the extract.

This experiment was conducted to evaluate the effect of marjoram powder (Origanummajorana L.) as an antibiotic growth promoter substitution on performance and immune responses in broiler chicks. Three hundred day-old broiler chicks were divided randomly into four treatment groups included: control (Basal diet), antibiotic (Flavophospholipol) and marjoram powder at levels of 2 and 4 g/kg in basal diet. Body weight, feed intake and feed conversion were recorded at 14, 28 and 46 d. Antibody titer against Newcastle and Avian influenza (H9 N2) viruses at 26 d (14 d post immunization), SRBC at 32 d

(6 d post immunization) and heterophil to lymphocyte ratio at 42 d were measured. Results showed that the birds fed the 2 or 4 g/kg marjoram powder had higher final body weight than other treatments (P < 0.05). Feed consumption in antibiotic group was significantly decreased. Feed conversion ratio was not affected by dietary treatments. Antibody titer against Newcastle and influenza viruses were elevated in broiler chicks fed 4 g/kg marjoram powder (P < 0.05). Antibody titer against SRBC, albumin to globulin ratio and heterophil to lymphocyte ratio were not affected by dietary treatments. These results suggest that
