Pyranonaphthoquinone derivative dimer and naphthalene derivatives from Ventilago denticulata (willd.) roots: isolation, structure elucidation, and cytotoxic activity.
Phytochemical investigation of the roots of Ventilago denticulata afforded three previously undescribed metabolites, a pyranonaphthoquinone derivative dimer, ventilanone W (1), and two naphthalene derivatives, ventilagodenins C (2) and D (3), together with sixteen known compounds (4-19). The structures were established...
