Two new monoterpenes from the fruits of Illicium lanceolatum.
Two new monoterpenes, p-mentha-1(7),8-dien-2-O-β-D-glucoside and trans-2,4-dihydroxy-2,4-dimethyl-trans-1-acetic acid γ-lactone were isolated from the fruits of Illicium lanceolatum along with trans-2,4-dihydroxy-2,4-dimethyl-cis-1-acetic acid γ-lactone, (1R,2R,4R)-8-p-menthen-1,2-diol, trans-sobrerol, (1S,2S,4R)-p-menthane-1,2,8-triol and (1S, 2S, 4R, 8R)-p-menthane-1,2,9-triol. The structures of the isolates were confirmed by spectroscopic analysis and they showed no inhibitory effects on the in vitro growth of microbial organisms (Escherichia coli, Staphyloccocus aureus, Bacillus subtilis) at less than 1.0 mg/mL.
