The industrially extracted mimosa (Acacia mearnsii) tannin powder used in the current study was obtained from UCL Tannin Company Pty (Ltd), Kwa-Zulu Natal, South Africa. The extract was obtained from the bark of a Acacia mearnsii tree through a series of hot water extraction processes at a controlled temperature, pressure, and time, followed by vacuum evaporation and subsequent air-drying into fine powder before packaging and storage at −4 °C [16 (link)]. The molecular weight of the mimosa ranged from 500–3000 Daltons [24 (link)]. The organic solvents used were: ethyl acetate and pentanol, procured from Sigma Aldrich, Johannesburg, South Africa. According to Missio et al. [16 (link)], pentanol has a polarity index of 0.568, whereas ethyl acetate has a polarity index of 0.228. Tannic acid, Folin–Ciocalteu reagent, butanol, and all other reagents used were of analytical grades supplied from Sigma Aldrich, Johannesburg, South Africa.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
