Plant Extracts as Herbal Indicators
Year: 2025
Type: article
Abstract: When the pH of the solution is altered by adding acid or alkali, indicators—which are highly specific compounds—will cause the solution's color to change. Red cabbage's actual color is blue. It will be somewhat blue after cutting it up and adding some tap water, but it will turn red when vinegar is added. This is because the color in red cabbage acts as a pH sensor. The aim of this study is to examine the possibility of using extracts of flower pigments in place of synthetic indicators. Synthetic indicators are costly, problematic in terms of supply, and hazardous chemically. An essential part of determining the herbal markers is the use of plant extracts. We must adhere to a number of crucial procedures and approaches that may be used during plant extraction in order to preserve the stability and caliber of the indicator that is intended to be displayed.
