Abstract:

A high-performance liquid chromatographic (HPLC) method was established to determine abietic acid in duck
skin. Abietic acid in duck skin samples was extracted with acetonitrile, followed by purification with a C18 solid-phase
extraction cartridge, and determined by HPLC with an ultraviolet (UV) detector. The chromatographic conditions were
established using a C18 column (250 mm× 4.6 mm, 5 μm) with a mobile phase consisting of 0.003 mol/L phosphoric acidmethanol
(8:92, V/V) at a flow rate of 1.0 mL/min and the detection wavelength was set at 240 nm. Results indicated that
the linearity ranged from 0.1 to 10.0 mg/L, the detection limit of abietic acid was 0.1 μg/g, and the quantification limit was 0.33 μg/g.
The recoveries from spiked samples at concentration levels of 0.5–50 μg/g were in the range of 82.2%–88.0%. The
developed method was successfully applied to the determination of abietic acid in duck samples epilated with colophony.
The content of abietic acid in the duck sample could reach 14.52 μg/g. This method proved to be of high maneuverability as
well as excellent sensitivity and accuracy, and could be used for quantitative analysis of abietic acid in duck skin tissue.
