Comparative analysis of essential oil and fatty acid constituents of Abrus cantoni-ensis and Abrus mollis / 药学实践杂志

ABSTRACT

Objective To utilize and evaluate the resources of Abrus cantoniensis Hance (AC) and Abrus mollis Hance (AM ) by analyzing and comparing their essential oils and fatty acids .Method The essential oils of AC and AM were extracted with the hydro distillation method .Fatty acids were obtained by petroleum ether extraction of the 95% ethanol concentrate . Fatty acid extract was further reacted with BSTFA for GC-MS analysis .Components were identified by searching NIST MS library .Result Forty-two and thirty-three chemical constituents were identified from the essential oil of AC and AM respec-tively ,which accounted for 56 .76% and 63 .45% of their volatile components .( ± )-α-terpinyl acetate are the common essential oils found in both AC and AM .Thirteen and fourteen chemical constituents were identified from the fatty acid extract of AC and AM respectively .AC and AM have different chemical components and compositions .Conclusion Our results provide a sci-entific basis for the bioactivities ,quality control and resource utilization of AC and AM .
