Визначення кількісного вмісту проціанідинів плодів глоду
Aim. To determine the quantitative content of procyanidins in hawthorn fruits.Results and discussion. It was found that the quantitative content of procianidinsin Crataegus succulentha Sarg. fruits was 1.45 % ± 0.02; C. prunifolia Sarg. – 1.24 % ± 0.05; C. pseudokyrtostila Klok. – 1.15 % ± 0.03; C....

Journal of Organic and Pharmaceutical Chemistry| Резюме: | Aim. To determine the quantitative content of procyanidins in hawthorn fruits.Results and discussion. It was found that the quantitative content of procianidinsin Crataegus succulentha Sarg. fruits was 1.45 % ± 0.02; C. prunifolia Sarg. – 1.24 % ± 0.05; C. pseudokyrtostila Klok. – 1.15 % ± 0.03; C. leiomonogyna Klok. – 1.28 % ± 0.04; C. arnoldii Sarg. – 1.38 %± 0.02; C. submollis Sarg. – 1.37 % ± 0.03; C. mollis Sarg. 1.48 % ± 0.01.Ехperimental part. The content of procyanidins was determined by the spectrophotometric method calculated with the reference to cyanidin chloride. The optical density of the test solution was measured at a wavelength of 545 nm. The study was performed on a Thermo Fisher Scientific model EVOVUTION 60S spectrophotometer.Conclusions. Procyanidins of fruits of 7 nonofficinal species of the genus Crataegus L. have been studied. It has been determined that all samples under research meet the requirements of the SPhU and EuPh by the indicator “Assay for procyanidins”, which should be at least 1 %. |
