title: [Analysis of chemical components in Aconitum kusnezoffii leaves and their extracts by infrared spectroscopy].
abstract: Aconitum kusnezoffi leaves and their extracts were analyzed and evaluated by fourier transform infrared spectroscopy, second derivative spectra, and two dimensional correlation infrared spectroscopy in this research. There was characteristic IR absorption peaks of polyose (767 cm(-1)) in the Aconitum kusnezoffii leaves. The IR spectra of the aether extract were similar with the ethanol extract of Aconitum kusnezoffi leaves. The strong absorption peaks of carbonyl (1 715 cm(-1)) and saturated alkyl groups (2 921, 2 851 cm(-1)) could be detected. Some fatty acids were also detected in the water extract. Infrared spectroscopy, combined with two dimensional correlation infrared spectroscopy, can provide much structural information for herbs, which will benefit the quality control, components tracing and identification of extraction process of herbs roundly and qualitatively.
