The goal of the current study was to examine the phytochemical and proximate profile of Diapensia himalacia leaf extracts. A key source of treatment for a variety of human maladies has been medicinal plants. An important criteria to spot drug adulteration or inappropriate treatment was the pharmacognostic evaluation of the plant material. Ash values of Diapensia himalacia leaves were examined in the current study. The extractive yields of leaves from Diapensia himalacia were determined using five different solvent extracts (petroleum ether, chloroform, ethyl acetated, methanol, and water). Both the leaf powder and the solvent extracts underwent a fluorescence analysis. In both leaf samples, total ash levels were found to be higher than acid insoluble and water soluble ash. When extracted in a methanol solvent, the leaf extracts under study demonstrated substantial extractive yields. The highest amounts of extractive yield, total ash, water soluble ash, and acid insoluble ash were found in Diapensia himalacia. Diapensia himalacia leaf extracts and leaf powder underwent fluorescence analysis, which exhibited unique colouring with various chemicals.
