URINARY METABOLOMICS STUDY ON THE PROTECTIVE ROLE OF ORTHOSIPHON STAMINEUS IN STREPTOZOTOCIN INDUCED DIABETES MELLITUS IN RATS VIA 1H NMR SPECTROSCOPY
DESCRIPTION : Orthosiphon stamineus (OS) is a herb known in ethnomedicine for treating diabetes mellitus (DM). In this study, a 1H NMR based urine metabolomics tool has been used for the first time to identify the metabolic protective mechanism of OS in DM using Streptozotocin (STZ) induced experimental model in rats. Methods Four different solvent extracts of OS, namely aqueous, ethanolic, 50% aqueous ethanolic and methanolic, at a dose of 500Â mg/kg body weight (bw) were orally administered for 14 days to diabetic rats induced via intraperitoneal injection of 60Â mg/kg bw STZ. NMR metabolomics approach using pattern recognition combined with multivariate statistical analysis was applied in the rat urine to study the resulted metabolic perturbations. Results OS aqueous extract (OSAE) caused a reversal of DM comparable to that of 10Â mg/kg bw glibenclamide. A total of 15 urinary metabolites, which levels changed significantly upon treatment were identified as the biomarkers of OSAE in diabetes. A systematic metabolic pathways analysis identified that OSAE contributed to the antidiabetic activity mainly through regulating the tricarboxylic acid cycle, glycolysis/gluconeogenesis, lipid and amino acid metabolism. Conclusions The results of this study validated the ethnopharmacological use of OS in diabetes and unveiled the biochemical and metabolic mechanisms involved.

ANALYSIS OF PINK PILL BY ATR-FTIR
DESCRIPTION : The IR transmission spectra of a pink pill sample labeled as MRM was obtained using attenuated total reflectance (ATR)-FTIR IRTracer-100 (Shimadzu) spectrometer. The spectra were obtained between 400 and 4000 cm-1 with 36 scans at 4 cm-1 resolution.

A SCALED SUBTRACTION OF ATR-FTIR SPECTRA AND SPECTRA IDENTIFICATION USING SPECTRAL LIBRARY DATABASES
DESCRIPTION : With the help of the three IR spectral libraries of General Library IR (350 spectra), SWGDRUG IR library-31 May 2018 (503 spectra) and Demo Library (200 spectra), the subtracted FTIR spectra were successfully identified after spectral library search. The spectral matching operation was performed by software algorithm (standard search algorithm) with one main component mode in OPUS (Bruker).
