THE MORPHOLOGICAL AND ANATOMIC SINGNS AND NUMERICAL INDICATORS OF FLOWERS OF THE CRATAEGUS MACRACANTHA L

Abstract

Purpose: the study of morphological and anatomical features and the determination of some numerical indicators for the flowers of Crataegus macracantha.Material and methods. The objects of the study were dried flowers of Crataegus macracantha. All studies were carried out according to the methods described in the State Pharmacopoeia XIV of the Russian Federation. Microscopic analysis was performed using an MVZ-103 microvisor. In the quantitative determination of flavonoids, Sorbfil chromatographic plates (TU 4215-002-43636866-2007) and a SHIMADZU UV 1800 spectrophotometer (Japan) were used.Results and discussion. The main morphological and anatomical features of Crataegus macracantha flowers were studied. Some numerical indicators were determined in the flowers of Crataegus macracantha: the content of hyperoside is 1,01±0,04%; the moisture content is 9,06±0,41%; the total ash content is 10,61±0,50%; the content of ash insoluble in hydrochloric acid 10% is2,05±0,05%. The data comply with the requirements of pharmacopoeial monograph 2.5.0062.18 «Hawthorn flowers».Conclusions. The studied indicators confirm the feasibility of using this species of Crataegus macracantha as a hawthorn flower producing plant and can be used for further research to develop regulatory documentation.
