GC–MS Analysis of A Helichrysum italicum Hydrosol: Sensitivity, Repeatability and Reliability of Solvent Extraction versus Direct Hydrosol Analysis

Hydrosols have been increasingly used in the food industries as drinks and ingredients for seasoning flavoring. Research has shown they antimicrobial, antioxidative anti-inflammatory effects therefore potential preservative agents sanitizing tools industry. The composition analysis of hydrosols is commonly conducted using extraction with organic solvents. However, some hydrophilic compounds are lost this procedure, leading to issues identifying native adulteration. In paper, different methods hydrosol studied. differ sample preparation, number detected compounds, repeatability reliability. Direct 1:1 solvent were determined be most appropriate our experiments. method implementation depends on application. simple does not change ratios among compounds; its drawback poor repeatability. Using good repeatability; however, lost, adulterations cosolvents addition solubilizers cannot discovered.
