Principle and Steps Involved in Gravimetric Analysis: Gravimetric analysis is a classical quantitative analytical technique in which the amount or concentration of an analyte is determined by measuring the mass of a pure compound containing the analyte. It is one of the most accurate methods of quantitative analysis because the final measurement is based directly…
Estimation of Sodium Benzoate: Sodium benzoate (C₆H₅COONa) is the sodium salt of benzoic acid and is widely used as a preservative in pharmaceutical preparations, foods, and beverages. It can be estimated by acid-base titration. Since sodium benzoate is the salt of a weak acid and strong base, it reacts with a strong acid such as…
Estimation of Weakly Acidic and Basic Substances: Non-aqueous titration is an acid-base titration carried out in a solvent other than water. It is especially useful for the estimation of weakly acidic and weakly basic pharmaceutical substances that cannot be titrated accurately in aqueous media. In water, weak acids and bases may undergo incomplete ionization, resulting…
Preparation and Standardization of Acidic and Basic Titrants: In volumetric analysis, a titrant is a solution of known concentration that is used to determine the concentration of an unknown solution. Acidic and basic titrants are commonly used in acid-base titrations. Before use, the concentration of a titrant must be accurately determined by standardization against a…
Non-Aqueous Titrations: Non-aqueous titration is a volumetric analytical method in which the titration is carried out in a solvent other than water. It is particularly useful for the assay of weak acids, weak bases, and substances that are poorly soluble in water. In aqueous titration, weak acids or bases may not ionize sufficiently to give…
Boots Flu Jab 2026 is a seasonal influenza vaccination service available at participating Boots pharmacies in the UK. Eligible people may be able to receive the NHS flu vaccine free of charge, while private vaccination may also be available for people who do not qualify for NHS vaccination. This guide explains the Boots flu jab…
Eco-Pharmacognosy in Sustainable Conservation of Endangered Medicinal Plants: Eco-pharmacognosy is an emerging approach that combines the principles of pharmacognosy, ecology, biodiversity conservation, and sustainable utilization of medicinal plants. It focuses on understanding medicinal plants in relation to their natural habitats, ecological requirements, harvesting practices, chemical constituents, and sustainable use. Medicinal plants such as Kutki (Picrorhiza…
Ex-situ and In-situ Conservation: Medicinal plants are an important source of therapeutic agents, traditional medicines, nutraceuticals, cosmetics, and pharmaceutical raw materials. Plants such as Withania somnifera (Ashwagandha), Azadirachta indica (Neem), Rauvolfia serpentina (Sarpagandha), Aloe vera, Ocimum sanctum (Tulsi), and Phyllanthus species have significant medicinal and economic value. However, increasing demand, habitat destruction, overharvesting, climate change,…
Application of Polyploidy: Medicinal plants are one of the most valuable natural resources because they produce a wide variety of secondary metabolites, such as alkaloids, glycosides, flavonoids, tannins, terpenoids, saponins, essential oils, phenolic compounds, and steroids. Unlike primary metabolites, which are directly involved in the growth and survival of plants, secondary metabolites are not essential…
Plant Hormones and Their Applications: Plant growth and development are controlled by a group of naturally occurring chemical substances known as plant hormones or phytohormones. These hormones are produced in very small quantities within different parts of the plant and act as chemical messengers that regulate various physiological and biochemical processes. Unlike nutrients, which are…
