aimed at providing the biochemical characteristics and comparing the biochemical
composition of extracts obtained with the help of different extracting agents. The list
of chemical combinations necessary for the determination, was selected in compliance
with the common studying of allergic preparations. In the extracts, both the content of
protein and polysaccharides, and nucleic acids were determined. In the allergen with
the complete set of determinants, the probability of detecting the candida infection of
patients is higher.
The Table 1 provides the chemical content of the obtained extracts of fungus
C. albicans. The results of studying the extracts obtained testify that in 5.0 % extract
of the sodium hydroxide solution the greatest amount of the studied substances was
found.

Remarks:
1) 1- extraction with 5.0 % solution of sodium hydroxide, 2 – extraction with 5.0 % solution of
hydrochloride acid, 3 – extraction with 0.9% of sodium chloride;
2) n = 5, Р<0.5
The cellular polysaccharides of the fungus C. albicans are represented by several
monosaccharides. The qualitative determination and quantitative comparison of
monosaccharides were conducted according to the intensity of spots coloring during
the paper chromatography.
To determine the monosaccharide composition of polysaccharides of the obtained
extracts the paper chromatography was conducted.
The polysaccharides of extract 5.0% of the sodium hydroxide solution were
represented by monosaccharides: mannose, glucose, tracks of ribose and two non-
identified monosaccharides. The polysaccharides of extract with 5.0% of the sodium
hydroxide solution of isotonic 0.9 % solution of sodium chloride were represented by
the same specter of detected monosaccharides but the spots were less intense, which
testifies to the smaller amount of monosaccharides in these extracts.
Grounding of the optimal technology of obtaining the extract from the
Сandidaalbіcans fungus biomass. Noteworthy that the easiest way of influencing the
mass output from the particle surface to the free extracting agent is through the creation
of the liquid movement around the particles or mixing the whole mass of the extraction
mixture which is performed during the following extraction methods: percolation,
repercolation, maceration with mixing or circulation of the extracting agent. During
these methods, the extracting agent moves against the raw material [6, 7]. Thus, many
