Quantitative estimation of polyphenols among terminalia-arjuna populations collected from different sites of Chhattisgarh and Madhya Pradesh, India

摘要

The objective of the present work was to assess variation in total phenolic content in Terminalia arjuna populations from different locations of Madhya Pradesh and Chhattisgarh. Different regions of Madhya Pradesh and Chhattisgarh were surveyed and bark samples from phenotypically superior population was collected. A spectrophotometric method was used for quantification of phenols using Folin-Ciocaltue reagent. The results were expressed as milligrams of gallic acid equivalent per gram of dry weight (GAE g/dw). Significant (P=0.01) variation was observed in polyphenols in different populations of T.arjuna. The quantity of polyphenols varied 12.20 to 15.94%. Among six selected populations, phenolic content was found to be maximum in Bilaspur, CG germplasm (15.94mg/100gm) followed by Mandla, MP (15.07mg/100gm). Seoni, MP, germplasm contained the minimum amount of phenolic content (12.20 mg/100gm). A significant correlation was found between the bark thickness and phenolic contents. The populations with high phenolic contents can be utilized for mass multiplication and genetic improvement.
