ABSTRACT Introduction: Processing of crude drugs helps the transformation of the pharmacological action of a drug bestowing it with better efficacy and greater bioavailability. Lesser explored traditional practices have many such single drug therapies that can ​ be brought into the limelight. One such folklore practice is Taila Paka of Karmaranga (Averrhoa carambola Linn.) Phala ​ ​ ​ ​ which is used traditionally in treating joint disorders. Standardization of drugs is of paramount importance in order to deliver a promising treatment with respect to safety and efficacy, with this background the oil prepared using Karmaranga fruits is ​ taken for its analytical study. Methods: The present study exclusively deals with the physico-chemical analysis of Karmaranga Taila by standard oil ​ ​ ​ ​ parameters including High-performance thin-layer chromatography (HPTLC). ​ ​ Results: The sample was liquid at room temperature with a reddish-brown color and agreeable odor. As the fruits are rich in ​ vitamin C, HPTLC was done along with ascorbic acid running parallel to the test sample. There were 3 and 7 bands respectively observed in short UV and long UV. Simultaneously ascorbic acid showed a blue fluorescent band at Rf 0.48, after derivatization with vanillin sulphuric acid spraying reagent, there were two bands evident in A.carambola oil at Rf 0.48 ​ and 0.57 (all purple). Conclusions: This study can serve as a standard reference for the preliminary identification of Karmaranga Taila. ​ ​ ​ _________________________________________________________________________________ ​ Keywords: HPTLC; Karmaranga Taila; Physico-chemical analysis; Traditional formulation. ​ ​___________​ ______________________​ _____________________________​ __________________ ​ INTRODUCTION Tremendous amount of traditional knowledge hidden Averrhoa carambola Linn., belonging to the family Oxalidaceae,2 commonly called star fruit in Indian within tribals on herbal medicine is unknown to the outer ​ world.
