What is Caryophyllene?

Caryophyllene is a natural bicyclic sesquiterpene that belongs to the class of compounds known as terpenes. It is found widely in nature, particularly in essential oils derived from various plants such as cloves, basil, hops, rosemary, and cannabis. Caryophyllene is notable for its spicy, woody aroma and is often used in perfumery and flavoring industries.

One unique characteristic of caryophyllene is its ability to act as a selective agonist of the cannabinoid receptor type 2 (CB2 receptor), which is part of the endocannabinoid system in mammals. This interaction gives caryophyllene potential therapeutic applications in areas related to inflammation, pain relief, and potentially other health benefits, similar to cannabinoids found in cannabis.

In addition to its pharmacological properties, caryophyllene is also studied for its antimicrobial, antioxidant, and anti-inflammatory effects, making it a subject of interest in both scientific research and commercial applications.

Title

Optimization and Validation of HPLC Methodology for the Analysis of C. verbenacea Essential Oil

Background

This study focuses on the development and optimization of a High-Performance Liquid Chromatography (HPLC) method for analyzing the essential oil of Cordia verbenacea, specifically targeting its main markers, carvacrol (CAR) and humulene (HUM). The aim was to achieve an ideal separation with accurate quantification, ensuring the method's applicability to commercial formulations like creams and aerosols.

Samples

The samples analyzed included essential oil from C. verbenacea, as well as commercial pharmaceutical formulations containing this essential oil in the form of aerosols and creams.

Technical Methods

Optimization of Chromatographic Conditions: The Box–Behnken experimental design was utilized to determine the optimal conditions. Mid-range settings were found ideal, with:

  • Flow rate: 1 ml/min
  • Column temperature: 40°C
  • HP-β-CD concentration: 20 mM
  • Solvent composition: 8% methanol, 51% HP-β-CD in aqueous solution (pH 3.0), 41% acetonitrile
  • Column: C4

Predicted and Experimental Values:

  • Predicted resolution values: RCMP1-CAR of 2.05, RCAR-CMP2 of 1.69, and CAR retention time of 32.7 min.
  • Experimental results: RCMP1-CAR of 1.81, RCAR-CMP2 of 1.66, and CAR retention time of 35.6 min.

Validation: The method was validated for linearity, selectivity, precision, accuracy, limit of detection (LD), and limit of quantification (LQ). The UV spectra and purity of chromatographic signals were confirmed with a similarity index higher than 0.9999. Linearity was proven with correlation coefficients (R²) over 0.99, and precision showed relative standard deviation (RSD) less than 5%.

Results

The developed method successfully separated and quantified CAR and HUM in C. verbenacea essential oil. The concentrations in commercial formulations (aerosols and creams) were close to the labeled amounts, demonstrating no significant interference from excipients. The resolution achieved was adequate, and the method's precision and accuracy were validated, ensuring reliable application in quality control and formulation studies. Specifically:

  • Aerosols: HUM concentrations were 2.85% and 2.87%, CAR concentrations were 10.30% and 10.43%.
  • Creams: HUM concentrations were 2.9%, CAR concentrations were 10.33% and 10.23%.

The method proved effective for both the identification and quantification of CAR and HUM, with CAR suggested as a marker for C. verbenacea essential oil due to its higher concentration relative to HUM.
