ANALYSIS OF SOUTHWESTERN COLORADO LIGUSTICUM PORTERI BY GAS CHROMATOGRAPHY - MASS SPECTROMETRY
1Department of Chemistry, San Juan College, Farmington, NM 87402.
Abstract:
Osha root (Ligusticum porteri) is a perennial herb found in parts of the Rocky Mountains. It is used as an immune booster and a treatment for colds, flus, indigestion, and body aches. In this study we determined compounds present in osha root from the San Juan Mountains in Southwestern Colorado by Gas Chromatography - Mass Spectrometry. Extractions were performed using hexane and methanol solvents at room temperature. Some thirty to forty compounds were detected. Eleven compounds with a high search indices are discussed and compared with previous studies.
