Study On DPPH Free Radical - Scavenging Activity Of Antioxidant Compounds In Plants Composing BIN-5 Biological Active Preparation

Recently there has been common trend among people to refuse from food and medications produced via synthetic method but try to consume natural products as much as possible instead. In this regard wild berries and medicinal plants are considered to be highly essential for human health as these kinds of plants serve as rich sources of biological active substances-phenol compounds. As a result of conducting research on source and spread of herbs which are commonly used as anti-diabetic medication we have developed a technological method to extract preparations from medicinal herbs such as Peony Paeonia lactiflora Pall Dandelion Taraxacum officinalis Wigg. Huckleberry Vaccinium myrtillus L Blueberry Vaccinium uliginosum L Cranberry Vaccinium vitisidaea L and Stinging nettles Urtica dioica accordingly studied chemical composition and antioxidant activity and conducted pharmacological study. With the use of Folin Denis 26 Folin Ciocalteu reagent methodit was determined that the content of polyphenol compounds was 4.14-5.17 and 27.5 101.5mgml. The study was also aimed to investigate DPPH free radical-scavenging activity in connection with term temperature and concentration to identify the most rational technological procedure. As a result of study it was identified that free radical-scavenging activity of herbs selected for the study was generally estimated at 564.25-1750.00 mcgml whereas antioxidant activity of solvents with 2-10 mgml concentration was 417.20-1750.00 mcg ml respectively. This shows that such activity is dependent on concentration. However in temperature of 30 1000261057 degrees their activity has slowly been decreased by 1750 mcgml 476.7mcgml depending on temperature. Regarding the stinging nettles the activity was grown directly dependent from temperature. DPHH free radical-scavenging activity was gradually increased in 1-10 minutes but was relatively stable and active in 11-16 minutes.
