GC/MS analysis and analgesic effect of the essential oil of Matricaria pubescens from Algeria.
Résumé
The essential oil of Matricaria pubescens (Asteraceae) collected at Ghardaia (Algerian Septentrional Sahara) was studied by GC and GC-MS. Isochrysanthemic acid ethyl ester (26.5%), spathulenol (19.4%), alpha-cadinol (12.9%) and geranylisovalerate (8.2%), were identified as the major components of the essential oil, which was investigated for its analgesic effect.
