The present enquiry was intended to analyze the phytochemicals qualitatively and quantitatively from flowers of Spanish cherry tree. Flower powder was extracted using polar and nonpolar solvent by soxhlet apparatus. Percentage yield of crude extracts was determined and further the extracts were subjected to analyze the phytochemicals qualitatively and quantitatively by standard procedure. Qualitative analysis showed the absence of alkaloids while presences of tannins, saponins, terpenoids, steroids, glycosides, flavonoids, phenols. Quantitative estimation of phytochemicals was determined using standard curve. Result revealed that the tannin content was 4.3±0.01 (mgTAE /gm), flavanols content was 0.28±0.05 (mgQE/gm). Saponins content was 3.6±0.7 % and terpenoids content was 1.47±0.37 %. A well conducted studies on phytochemicals revealed that they are vital for humans because they provide protection against a variety of ailments. Therefore, the present study is aimed to analyze phytochemicals qualitatively and quantitatively. Keywords: Phytochemicals, Tannins, Saponins, Flavanols, Terpenoids

The qualitative and quantitative assessment of ground waters protectability based on the regional specific charac-teristics of the lithology and thickness of impermeable deposits of the zone of aeration and overlying deposits, a ratio of confined and ground water levels, the soils and clay rocks absorptivity. The article gives the author's vision of ground waters natural protectability. It presents a quantitative estimation by three most well-known methods. Based on the calculations made a map of protectability of fresh ground waters in the Atlym-Novomikhailovsk complex for Nizhnevartovsk district was constructed.

Abstract In article are brought algorithm and results brought numerically-experimental studies on qualitative and quantitative estimation of the law of the moving the raw cotton from directing walls outgoing between spiked-drum and netlike surface feeder aside worker of the camera ginning machines. It is known that the uniform supply of raw cotton to the ginning process has a direct impact on the efficiency of the ginning process. In the process of ginning, the cotton is cleaned on the surface of the pile drum and net of the supplier, and the crushed gin comes to the working chamber through the gin. As a result of the rotation of the saw cylinder in the working chamber, the cotton fiber is suspended and the rotation is started. As a result of the circular motion of the raw cotton, a raw material roller is formed. In this process, the actual problem is to ensure that the raw cotton consists of small pieces and is uniform in time and width of the equipment. The Comparison got given on calculation shows that increase the corner will bring about increase the growing forming displacement. Increase of this corner will bring the leaflet of the raw cotton about increase of length free moving.

Uncertainty as an attribute of fire and emerging risks has both objective and subjective origin. Like measure uncertainty in modern metrology, the uncertainty in the risk theory has qualitative and quantitative aspects. Several methods for uncertainty quantifying are known. Taking into account the specifics of dangerous industrial objects, the probabilistic approach to quantitative estimation of their risk parameter uncertainty is inapplicable. A good alternative is to assess the fire and emerging risks in the interval setting. In addition to directly assessing the uncertainty of the results obtained — the risk indicators — it also makes it possible to estimate the parametric sensitivity of the model and to assess the conservatism of the assumptions made.

Latent form of monophenolase of mushroom polyphenol oxidase (PPO) was activated by 0,1% sodium dodecyl sulfate (SDS). The addition of increasing concentrations of 4-methylcatechol di minished lag period of active and total monophenolase activity, measured using p-cresol with L-proline as a substrate. Changes of lag period were described by equation of one phase exponential decay when concentration of substrate varied from l to 10 mM. Affinity ( 1/K<sub>m</sub>) toward substrate of latent monophenolase was over two times higher than that of the active form, while the maximum velocity (V<sub>max</sub>) was two times lower. The catalytic power (V<sub>max</sub>/K<sub>m</sub>) of both forms of monophenolase were almost equal. Electrophoretic analysis followed by scanning technique of the gels was used. Absorbancy of spots, determined from computer image of isoenzyme bands pattern allowed for qualitative and quantitative estimation of electrophoregrams. Presence of one additional clearly defined slow migrating isoenzyme for SDS activated monophenolase differed in this respect active (2 bands) and total (3 bands) forms of monophenolase.
