[A new quinoline alkaloid from Scolopendra subspinipes mutilans]

Three compounds, including scolosprine C(1), uracil(2) and hypoxanthine(3), were isolated and purified from the ethyl acetate fraction of centipede by silica gel normal-phase column chromatography, reversed-phase medium pressure preparation chromatography, and high-pressure semi-preparative HPLC. The structure was elucidated through a combination of spectroscopic analyses [such as nuclear magnetic resonance(NMR) and mass spectrometry(MS)] and literature review. Among them, compound 1 was a new quinoline alkaloid. In previous reports, we have described the isolation and structure elucidation of one new and two known quinoline alkaloids. In this paper, we would report the isolation and structure elucidation of scolosprine C in detail.
