Volatile components from Anthriscus sylvestris (L.) Hoffm

Area of Science:

• Phytochemistry
• Natural Product Chemistry
• Analytical Chemistry

Background:

• Anthriscus sylvestris (L.) Hoffm., commonly known as wild beaked parsley, is a plant species with potential applications.
• Understanding the volatile composition of its different parts (leaves and roots) is crucial for exploring its uses.

Purpose of the Study:

• To identify and quantify the volatile components of fresh Anthriscus sylvestris leaves and roots.
• To compare the efficacy of hydrodistillation versus dichloromethane extraction for volatile compound analysis.
• To assess the impact of drying methods (air drying, freeze drying) on volatile constituent preservation.

Main Methods:

• Hydrodistillation of fresh Anthriscus sylvestris leaves and roots.
• Extraction using dichloromethane for fresh and dried leaf and root material.
• Analysis of volatile components using Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS).

Main Results:

• Monoterpenes constituted the dominant fraction (69-70%) in both leaf and root oils.
• Beta-phellandrene (39-45%) was the primary component in both leaf and root oils.
• Other significant components included beta-myrcene, sabinene, Z-beta-ocimene, and alpha-pinene.
• Dichloromethane extracts contained similar constituents but in much lower percentages compared to hydrodistillation.
• Drying processes (air and freeze drying) led to a significant loss of volatile compounds.

Conclusions:

• Hydrodistillation is more effective than dichloromethane extraction for analyzing volatile compounds in Anthriscus sylvestris.
• Fresh plant material yields a richer volatile profile compared to dried material.
• Drying significantly diminishes the volatile content, impacting potential applications of Anthriscus sylvestris extracts.
