The extract was analyzed to examine its physico-chemical properties (acid value, iodine value, peroxide value, viscosity, saponification value, moisture and ash content, refractive index, smoke, flash and fire points and specific gravity) and structural elucidation by standard methods and instrumental techniques.

After methylation, hydrolysis, reduction, and acetylation, the pattern of fragmentation of the mass spectrum of the final product was compared to reference standards for elucidation of the sugar skeleton.
This paper describes the sourcing and testing of 128 plant extracts using a MTT-based photocytotoxicity assay, and bioassay guided fractionation of one of the active samples Phaeanthus ophthalmicus, identification of known photosensitisers in the extracts by comparing with in-house standards and isolation and elucidation of one new photosensitiser.
The curriculum now centred on the elucidation of the text of the standard compilation, harmonization of its decisions with extra-Mishnaic traditions recorded in other collections, and the application of its principles to new situations.
A number of potential metabolites were identified and annotated based on structural elucidation, literature search and comparison with commercial standards, when available (Table 2).
Stable genetic transformation represents the gold standard approach to the detailed elucidation of plant gene functions.
The isolation was done following standard procedures, while the structure elucidation was performed with the help of advanced spectroscopic (NMR, MS, etc).
The physical meaning of any NSL necessitates an elucidation as we already know that any standard Lagrangian encodes most of the information of a given dynamics, i.e., classical, quantum, or cosmological.
The structural elucidations are performed using standard spectroscopic techniques and computational calculations.
Overviews on neuropathological standard stains are provided elsewhere [ 46] For elucidation of epilepsy-related changes it proved beneficial to highlight the regional drop-out of nerve cells by cresyl violet-based stains such as Nissl stain (without myelin staining) or Kluver Barrera stain (with myelin staining).
