The total phenolic content can be calculated as gallic acid equivalent (GAE) by the following equation: T=CxV/M. T is the total phenolic content in mg·g-1 of the extracts as GAE, C is the concentration of gallic acid established from the calibration curve in mg·ml-1, V is the volume of the extract solution in ml and M is the weight of the extract in g.
Gallic acid equivalent (GAE) can be calculated by using a calibration curve generated from gallic acid standards. The GAE value is determined by comparing the absorbance of the sample at a specific wavelength to the calibration curve. The total phenolic content in the sample can then be expressed in GAE per gram or milligram of the sample.

Can Gallic acid be used as a standard for alkaloid separation in hplc?
No, Gallic acid is not typically used as a standard for alkaloid separation in high-performance liquid chromatography (HPLC). Alkaloids and phenolic compounds like Gallic acid have different chemical properties that may not make Gallic acid suitable as a standard for alkaloid analysis in HPLC. It is more common to use specific alkaloid standards for this purpose.
What acid does walnuts contain?
Walnuts contain alpha-linolenic acid (ALA), which is an essential omega-3 fatty acid that is beneficial for heart health and brain function.
What is the Chemical Formula for Tannin?
The chemical formula for tannin can vary depending on the specific type or source. However, in general, tannin is a complex mixture of polyphenolic compounds, predominantly composed of gallic acid units.
What type of acid is present in unripe mango?
Unripe mangoes contain oxalic acid. This acid is responsible for the tartness and astringency often present in unripe fruits. It is important to note that consuming large quantities of unripe mangoes can cause stomach irritation in some individuals.
It must have taken some gall in 1871 for Mendeleev to predict the existence of this low-melting metal then four years later eka-aluminum was discovered by a Gallic chemist?
Mendeleev predicted the existence of eka-aluminum (later named gallium) in 1871 based on gaps in his periodic table. Four years later, in 1875, French chemist Paul-Émile Lecoq de Boisbaudran discovered gallium which had similar properties to the predicted eka-aluminum. This discovery validated Mendeleev's periodic table and his prediction methods.
