Abstract Because Ayurvedic herbal preparations contain a myriad of compounds in complex matrixes, it is difficult to establish quality control standards for raw materials and to standardize finished Ayurvedic drugs. A novel, accurate, and valid fingerprint method was developed using HPLC for quality control of a traditional Ayurvedic Arjuna churna formulation, which is used as a cardiotonic drug. Comprehensive comparison of chromatograms of standardized formulation of Arjuna churna and marketed formulations revealed eight characteristic peaks in chromatograms, which unambiguously confirmed the presence of authentic raw material used in the formulation on the basis of their retention time values and UV data. An HPLC fingerprint was also developed for total sapogenins present in Terminalia arjuna. The six common peaks observed in chromatograms of isolated sapogenins, standardized formulations, and marketed formulations can serve as a quality control tool for qualitative estimation of total saponin glycosides present in an Arjuna churna formulation.

AbstractThe phenolic composition of Fetească neagră and Băbească neagră grapes from Dealul Bujorului vineyard (south-east Romania) was studied using the spectrophotometric and high-performance liquid chromatographic (HPLC) methods. The results revealed significant differences between these cultivars. Total anthocyanins ranged from 0.22-5.98 mg g
