ABSTRACT

Objective: To study the quinoline alkaloids from the ethanol extract of Scolopendra subspinipes mutilans (SSM). Methods: The chemical constituents were isolated and purified by macroporous resin column, medium pressure preparation chromatography, and semi-preparative HPLC. Their structures were elucidated by IR, MS, and NMR experiments. Results: Three quinolone alkaloids were obtained and identified as 3-hydroxy-4-methoxyquinolin-8-yl hydrogen sulfate (1), jineol-8-sulfate (2), and jineol (3), respectively. Conclusion: Compound 1 is a new compound from SSM.
