Uv-Vis Spectrum of Carvacrol
March 27, 2026
Access the UV-Vis Spectrum SIELC Library

If you are looking for optimized HPLC method to analyze Carvacrol check our HPLC Applications library
For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.
HPLC Determination of Carvacrol on Primesep B Column
July 29, 2024
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis of Carvacrol
Carvacrol (5-Isopropyl-2-methylphenol) is the main component of the essential oils of the Lamiaceae family of plants. Thymol and carvacrol can also be applied as an alternative antimicrobial agent against antibiotic-resistant pathogenic bacteria. Carvacrol can be retained in HPLC using Primesep B column with a simple isocratic method using a mobile phase consisting of acetonitrile (MeCN), water and phosphoric acid buffer. The analysis method can be UV detected at 200 nm.

HPLC Method for Thymol, Carvacrol on Primesep B by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Thymol and Carvacrol.
Thymol (2-isopropyl-5-methylphenol) is a natural monoterpenoid phenol derivative of p-Cymene. Thymol is the main monoterpene phenol occurring in essential oils isolated from plants such as the Thymus, Ocimum, Origanum, and other herbs with antimicrobial properties.
Carvacrol (5-Isopropyl-2-methylphenol), also known as cymophenol, is the main component of the essential oils of the Lamiaceae family of plant. It is used in food and cosmetics for it’s taste and aroma.
Thymol and Carvacrol can be retained in HPLC using Primesep B column with a simple isocratic method using a mobile phase consisting of acetonitrile (MeCN), water and phosphoric acid buffer. The analysis method can be UV detected at 200 nm.
