Summary of Project / Major Outcome /Achievements : For standardization and quality assessment parameters of medicinal plants in Ayurveda, spectroscopic metabolomics have been used for few medicinal plants from three different taste categories viz., sweet, pungent and multiple taste- Tribulus terrestris, Vitis vinifera and Glycyrrhiza glabrafrom; sweet category; Piper longum, Cuminum cyminum, Capsicum annum from pungent group; Emblica officinalis with five tastes. While Electronic tongue was used for evaluation of the sensorial property of taste, the chemical properties were studied with Nuclear Magnetic Resonance (NMR), Fourier Transform Infra-Red (FTIR) and Laser Induced Breakdown Spectroscopy (LIBS). In terms of taste and phytochemical profiles all samples were unique but with similarities within each group. While the sensor response in E-tongue showed similarities within the sweet and pungent categories, NMR spectra in the aromatic region showed close similarities between the plants in the sweet category. The sensory, phytochemical and phytoelemental profiles of E. officinalis (with five rasa) in particular, were unique. In conclusion, combined sensorial and chemical descriptors is a promising approach for a comprehensive evaluation and fingerprinting of the Ayurvedic pharmacological parameterrasa.
