Determination of total phenolic compounds content in Rhaponticum carthamoides (DC. Iljin) by spectrophotometry method in different vegetation phases

Abstract

Since ancient times people were using various herbs to heal illnesses, regain strenght and improve health. One of many valuable herbs is Rhaponticum carthamoides (DC. Iljin) (also known as Maral root). Rhaponticum carthamoides is poorly examined. For our experiment we use Rhaponticum carthamoides (DC. Iljin) (rootstock, blossom and leafs) collected and prepared in Vytautas Magnus University botanic garden. There was analysed these 5 phases: intensive growth (2012-05-21), budding (2012-05-28), blossoming (2012-06-01), massive blossoming (2012-06-05), ending of blossoming and frudification (2012-06-18). We made methanol extract and then started the determination. The results showed that the biggest amount of phenolic compounds were found in massive blossoming phase. Phenols determine plant colours, smell, affects growth.
