YAN, CHEN; XING YU, JIANG; XING, TONG  e  XIAO QING, CHEN. COMPARISON OF VOLATILE COMPONENTS FROM MARCHANTIA CONVOLUTA OBTAINED BY MICROWAVE EXTRACTION AND PHYTOSOL EXTRACTION. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.2, pp.1518-1522. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072008000200016.

The volatile oils from Marchantía 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 (El, 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
