Significance of Ash value
Ash value is a critical measurement that determines the quantity of inorganic material in a substance, reflecting its purity and composition. It assesses the total mineral content in plant materials, playing a vital role in quality assessment and identifying possible adulterants. By measuring the inorganic residue left after combustion, ash value serves as an indicator of the purity and authenticity of herbal materials. It is essential for evaluating the quality of drugs and ensuring their integrity through quantitative analysis.
