Description

Description générale

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Application

• Phytochemical Profiling and Biological Potential of Prunus dulcis Shell Extracts.: Cyclohexane is utilized here for the extraction and analysis of bioactive compounds in almond shells, illustrating its application in natural product chemistry and analytical methodologies. The study underscores cyclohexane′s effectiveness in extracting valuable phytochemicals for potential therapeutic and commercial use (Ben Khadher T et al., 2023).


• Determining the Antibacterial Effect of Mentha Longifolia Essential Oil on Cariogenic Bacteria and Its Compounds: an in vitro Study.: In this study, cyclohexane is employed as a solvent to isolate essential oils for antibacterial testing, highlighting its critical role in enhancing the efficacy of natural antimicrobial agents. The research contributes to the development of cyclohexane-based methods for studying and applying essential oils in dental health (Shazdehahmadi F et al., 2023).
