Abstract

A new naphthoquinone, named eleuthinone A ( 8), two new Anthraquinones, named eleuthraquinone A and B ( 12, 13), a naphthalene derivative, named eleucanarol ( 14) were isolated from the bulbs of ELEUTHERINE AMERICANA, together with two new natural products previously synthesized, and nine known compounds. Their structures were established based on spectroscopic evidence. Their Antibacterial activities against STAPHYLOCOCCUS AUREUS ATCC25923 and ATCC27664, an enterotoxin producing strain were investigated.
