Analysis of Volatile Components of Adenosma indianum (Lour.)‎ Merr. by Steam Distillation and Headspace Solid-Phase Microextraction

Abstract EN

The essential oil of Adenosma indianum (Lour.) Merr.

plays an important role in its antibacterial and antiphlogistic activities.

In this work, the volatile components were extracted by steam distillation (SD) and headspace solid-phase microextraction (HS-SPME) and analysed by gas chromatography-mass spectrometry (GC-MS).

A total of 49 volatile components were identified by GC-MS, and the major volatile components were α-limonene (20.59–35.07%), fenchone (15.79–31.81%), α-caryophyllene (6.98–10.32%), β-caryophyllene (6.98–10.19%), and piperitenone oxide (1.96–11.63%).

The comparison of the volatile components from A.

indianum (Lour.) Merr.

grown in two regions of China was reported.

Also, the comparison of the volatile components by SD and HS-SPME was discussed.

The results showed that the major volatile components of A.

indianum (Lour.) Merr.

from two regions of China were similar but varied with different extraction methods.

These results were indicative of the suitability of HS-SPME method for simple, rapid, and solvent-free analysis of the volatile components of the medicinal plants.
