Extraction products from kind Lonicera vegetative parts usage possibility

Abstract

Abstract At present time the need of biologically active substances and preservatives as natural extract usage is increasing. Local recourses’ applying, in particular, honeysuckle common growing in the Krasnoyarsk territory is a justified decision. The results of vitamin C keeping dynamics in the separate vegetative parts of wild-growing blue honeysuckle depending on storage conditions are presented. It was shown that ascorbic acid is in 1.4 times higher in freshly picked berries in comparison with leaves. However acid content in berries subjected to deep freezing is decreasing over time and six month later it is only 68% from the original. At the same time vitamin C keeping in the leaves dried to air-dry condition is rather higher and to the end of storage period (6 months) is decreased only to 5.2%. Herewith the total amount of ascorbic acid in the leaves is higher than that in the frozen berries of the investigated plant. Besides that the spectrophotometric research showed the presence in the blue honeysuckle leaves (Lonicera caerulea L.) such classes of biological active compounds as chlorophyll containing derivatives, bioflavonoid complex, carbohydrate components, anthocyans, tanning agents, organic matters and so on. This circumstance suggests great perspectives for the vegetable raw material practical applying.
