Studying
of Anthocyanins of Cerasus Vulgaris Mill. Species Spreading in the Territory of
Nakhchivan Autonomous Republic and its Application as pH Indicator by Rahimova

Biomedical Science (OAJBS)
The
color of anthocyanins changes not only according to their chemical structure,
but also according to the pH and concentration of the medium. The most
influential are their pH values for color and consistency. Extraction and
purification of anthocyanin pigments from Cerasus vulgaris Mill. species was
successfully carried out. According to the obtained Rf values and UV
wavelengths, it was determined that component A was cyanidin 3-sophoroside,
component B was cyanidin 3-glucosylrutinoside, component C was cyanidin
3-glucoside, and component D was cyanidin 3-rutinoside. Also, UV spectrum of
components were measured. The Rf value in the solvent system of component A was
0,26 and 0,18 in the II, and the UV wavelength was 524, 529, 530 nm,
respectively, according to the relevant solvents. In the solvent system of
component B, the Rf value was 0,40, in the II 0,17, and the UV wavelength was
528, 531, 540 nm, respectively, according to the relevant solvents. In the
solvent system of component C, the Rf value was 0,40, in the second 0,30, and
the UV wavelength was 529, 537, 547 nm, respectively, according to the relevant
solvents. In the solvent system of component D, the Rf value was 0,44, in II -
0,20, and the UV wavelength was 516, 535, 545 nm, respectively, according to
the relevant solvents.
