Abstract: The chemical composition of Lepidium meyenii.(maca) root samples from Lijiang was analyzed by pyrolysis-GC-MS. Forty-nine pyrolysates were identified, mainly including phenols, ketones, aldehyde, olefins, aromatics, terpenes and heterocyclic and other compounds. Among them, phenol (6.274%), isopropyl myristate (4.702%) and 2,3-dihydrobenzofuran (4.433%) were the predominant compounds. Meanwhile, 25, 19 and 2 compounds were determined to have a relative content of more than 1%, more than 0.5% and less than 0.5%, respectively. D-limonene, 2,3-dimethyl-2-cyclopenten-1-ketone, benzene acetonitrile, indole and naphthalene were also found.

Key words: maca (Lepidium meyenii), pyrolysis, gas chromatography-mass spectrometry (GC-MS)
