A CRITICAL DRUG REVIEW ON ARKA KALPANA
Background: Arka Kalpana is one of the important drug dosage form. Arka Kalpana is correlated with Distillation in modern pharmaceutics practices. Arka is a liquid preparation obtained by distillation of certain liquids or of drugs soaked in water using the Arka yantra or any convenient modern distillation apparatus. In this study, preparation and standardization of Vachadi Arka and Supachya Arka two drugs was done as per API standards. Material and method: The drugs were collected and authenticated from the experts. The Arka was prepared as per classical methods. Standardization was done on the basis of organoleptic characters, physicochemical parameters like volatile matter (%), specific gravity, refractive index, pH, total acidity, viscosity and boiling point. Result: The result of the standardization revealed that Vachadi Arka is colourless with aromatic odour and Kashaya Madhura Rasa, Volatile matter is 19.49%, specific gravity is 1.0029, Refractive index is 1.33, pH is 6, total acidity is 0.13, viscosity is 0.96, and boiling point is 1000C. Supachya Arka is colourless with characteristic odour and Tikta Rasa, Volatile matter is 14.33%, specific gravity is 0.9842, Refractive index is 1.33, pH is 6, total acidity is 0.010, viscosity is 0.96, and boiling point is 1000C. Conclusion: Arka Kalpana acquires highest position in obtaining the potentially active volatile oils as the condensation takes place during the process of distillation. It has the significant role in traditional medicine. This article is a contribution for reviewing the Arka Kalpana as well as standardizing of two Arkas, i.e., Vachadi Arka and Supachya Arka.
