Comparison of Volatile Components From Marchantia Convoluta Obtained by Microwave Extraction and Phytosol Extraction

Abstract

The volatile oils from Marchantia convoluta were obtained by microwave extraction (ME) and phytosol extraction (PE) methods. The attained extracts were analyzed by gas chromatography with mass spectrometric detector (GC-MS). The compounds were identified according to their retention indices and mass spectra (EI, 70 eV). A total of fourteen compounds were identified in ME extract accounting for 80.72% of total peak area. Isolongifolene (24.588%), 1, 2-benzenedicarboxylic acid, butyl cyclohexyl ester (10.768%), pyrene (9.328%) and hexadecanoic acid, ethyl ester (8.570%) were the major compounds identified from ME extract. The analytical results of ME extract were compared with PE method. The ME extract was found to be markedly different from that of PE extract. A total of seven compounds in PE extract were identified accounting for 74.275% total peak area. 1-Phenanthrenecarboxylic acid, 1,2,3,4,4a,9,10, 10a-octahydro-1, 4a-dimethyl-7-(1-methylethyl) methyl ester were the major compounds.

Combined impact of pulsed electric field and ultrasound on bioactive compounds and FT-IR analysis of almond extract

“…Similar comparative results were observed for US, MW, hydro-distillation, soxhlet extraction and cold maceration treatment for Lonicera macranthoides volatile frictions (Wu et al 2015) as well as MW treated essential oil from aromatic herbs (Lucchesi et al 2004). A significantly higher amount of volatile compounds were identified after MW treatment from Marchantia convoluta as compared to phytosol extraction (Yan et al 2008) as well as MW assisted hydro-distillation treated essential oil from cinnamomum cassia as compare to hydro-distillation (Jeyaratnam et al 2016).…”
