Influence of growing conditions on the content of <i>Pentaphylloides fruticosa</i> flavonoids during introduction and in nature in the European North

Abstract

The paper studies the content of culture and wild samples of flavonoids Pentaphylloides fruticosa (L.) O. Schwarz in the European North. On the territory of the Komi Republic P. fruticosa requires conservation measures. The species is used as an ornamental, medicinal, food, honey and forage plant. When determining the pool of flavonoids of vegetative parts of one-year shoots in the flowering phase, it was found that they were significantly higher in wild samples than in introduced ones. This suggests that geographical growing conditions should influence the amount of flavonoids. The difference in the amount of flavonoids in the flowers between the wild and introduction of the samples was found. There were no significant differences between the introduced samples in the leafing phase and in the flowering phase. In the phase of mass fruiting the amount of flavonoids was significantly higher in sample № 1, due to their different ecological and geographical origin. It is advisable to introduce the culture of these natural samples that grow in the northernmost location in Europe, which can be a promising source of raw flavonoids and their further study in new growing conditions.
