Изучение стабильности биологически активных веществ в череды траве при хранении

Abstract

This work presents the results of studying the content variability of polysaccharides, flavonoids, luteolin-O-7-glucoside and luteolin in Bur marigold herb for 24 months of storage in whole and cut form in two types of packaging – paper bags and parchment bags, packed in cardboard boxes. It was found that a change in the content by 5% of the initial content of the pharmacological marker recommended by the herbal medicines committee of the European Medical Agency, in Bur marigold herb, was observed for polysaccharides when it was stored in whole form in closed paper bags after 6 months, when it was stored in cut form months in closed parchment bags packed in cardboard boxes – after 9 months; for flavonoids, these periods were respectively 6 months and 3-6 months. In Bur marigold herb stored in whole form for 24 months in closed paper bags, the content of polysaccharides is 79.80-85.58%, flavonoids – 58.24-82.05%, luteolin-O-7-glucoside – 44.54-70.60% of the initial, luteolin – 57.14-61.02% of the value determined after 12 months of storage. In Bur marigold herb stored in cut form for 24 months in closed parchment bags packed in cardboard boxes, the content of polysaccharides is 74.60-85.00%, flavonoids – 55.87-77.98%, luteolin-O-7-glucoside – 51.56-65.08% of the initial, luteolin – 44.99-54.82% of the value determined after 12 months of storage. Thus, the preservation of flavonoids (total and individual components), the type of packaging used for storage, and Bur marigold herb size have a significant effect, these factors do not affect the variability of the polysaccharide content during storage.
