Significance of Refractive index
Refractive index is a crucial physical property that quantifies how light is bent when passing through a substance. This measurement is vital for assessing the purity and concentration of oils and solutions in various applications, particularly in Ayurvedic formulations. It aids in identifying substances, confirming their quality, and evaluating properties such as transparency and molecular structure. The refractive index varies based on factors like temperature and concentration, making it a valuable analytical parameter in quality control and formulation studies.

The concept of Refractive index in scientific sources
Refractive index measures how light bends when entering various substances, revealing insights into their chemical composition and purity, particularly in oils and herbal preparations like Brahmi Ghrita and Tulasi Amla Yashti Ghrita.
From: World Journal of Pharmaceutical Research
(1) The measure of how much light is bent when entering a material, used to evaluate the transparency of emulsion systems.[1] (2) The ratio that describes how light is bent when passing through materials, indicating purity.[2] (3) A measure of how much light is bent when entering a substance, indicating the optical properties of the essential oil.[3] (4) A dimensionless number that describes how fast light travels through a medium compared to vacuum, which can change when an electric field is applied.[4] (5) A measure of how light is bent when it passes through a substance, which can indicate the composition of the oil.[5]
From: International Ayurvedic Medical Journal
(1) A measure of how much light is bent, or refracted, when entering a substance, used as a physicochemical parameter in the study.[6] (2) The measure of the speed of light in a medium compared to its speed in vacuum, indicating molecular compactness.[7] (3) A measure used in the analytical study of oils, indicating how much light is bent when entering the substance. The refractive index for Dashamoola Taila was noted at 1.47006 and for Dashamoola Ghrita at 1.46906.[8] (4) A measure that indicates the transparency and optical clarity of a syrup, evaluated as part of the physicochemical testing.[9] (5) A physical property defined as the ratio of the sine of the angle of incidence to the sine of the angle of refraction of light passing from air into a substance, used to identify substances and assess their purity.[10]
From: Journal of Ayurveda and Holistic Medicine

From: AYU (Journal of Research in Ayurveda)
(1) A parameter that indicates the concentration of active substances in Brahmi Ghrita, determined through analytical measurements.[14] (2) A measure of how light bends as it passes through Tulasi Amla Yashti Ghrita, which was observed as 1.4710 in the study.[15] (3) A measurement technique used to determine the properties of oils, indicating how much light is bent when passing through the oil.[16]
From: Ancient Science of Life
(1) A property measured in the analysis of 777 oil, indicating how light refracts through the substance.[17] (2) The refractive index is a physical characteristic of a material that describes how light travels through it, defined as the ratio of the speed of light in a vacuum to the speed of light in that medium.[18]
From: Journal of Ayurveda and Integrative Medicine
(1) A measure reflecting how light propagates through the ghrita formulations, which helps indicate their concentration and purity.[19] (2) A physical property that indicates the concentration of a substance, used to check the purity and quality of fats.[20]
From: Ayushdhara journal
(1) A measurement that describes how light is bent when entering a substance, important for characterizing the quality of the oils.[21]
