Analysis of Rodgersia aesculifolia Batal. Rhizomes by Microwave-Assisted Solvent Extraction and GC–MS

Abstract   Rodgersia aesculifolia Batal. rhizome is an effective antibacterial and antivirus Chinese medicinal plant. In this work focused microwave-assisted solvent extraction (FMASE) coupled with gas chromatography–mass spectrometry has been used for analysis of Rodgersia aesculifolia Batal. rhizomes. The main compound classes in the extract were fatty acids (67.22%), aliphatic hydrocarbons (9.02%), and steroids (7.02%). Oleic acid, linoleic acid, and palmitic acid were the most abundant compounds. Compared with Soxhlet extraction, the much shorter extraction time and the similar components in the extract make FMASE an excellent alternative for extraction of the components of plant rhizomes.
