Abstract

Study of the chemical constituents of the roots of Plumbago zeylanica L. collected in Taiwan led to the isolation and identification of a new naphthoquinone dimer, plumzeylanone (1), along with eight known compounds (2–9). Nine naphthoquinones isolated from this plant were assayed for cell growth inhibition activity using NALM-6 (human B cell precursor leukaemia), A549 (human lung adenocarcinoma), Colo205 (human colorectal adenocarcinoma) and KB (human epidermoid carcinoma). Plumzeylanone (1), a novel plumbagin dimer, suppressed cell proliferation in only NALM-6 cells (IC50 3.98 μM). However, maritinone (9) showed strong inhibition of cell growth in all cell lines tested (0.12 < IC50 < 9.06 μM). This compound appeared to affect the cell cycle.
