Abstract

Many plant species include tannins, which are water-soluble polyphenolic macromolecules that act as a defense against predators and may also help regulate plant growth. The purpose of this research was to assess the tannin content of several test extracts from test plant samples. Thirty separate samples of Acacia catechu bark were gathered for this purpose from Guna District, Madhya Pradesh, India, during various seasons. Six extracts were then prepared from each sample. After that, several techniques were used to determine if tannins were present in these extracts or not. The findings demonstrated that methanol, aqueous, and sometimes acetone extracts had a considerable quantity of tannin content; ethanol extracts, on the other hand, had a much lower tannin content, and both chloroform and benzene extracts were found to be free of the same. This exploratory study might serve as a foundation for further investigations on the best solvent to use for extracting tannin compounds from the materials under review.
