Two new sesquiterpenoids and one derivative, lycifuranone A (= (4 R )‐4,5‐dihydro‐4‐(3‐hydroxy‐2,6‐dimethylbenzyl)‐5,5‐dimethylfuran‐2(3 H )‐one; 1 ), lycifuranone B (= 4,5‐dihydroxy‐3‐methyl‐2‐{[(3 R )‐tetrahydro‐2,2‐dimethyl‐5‐oxofuran‐3‐yl]methyl} benzaldehyde; 2 ), and lycifuranone C (= (4 R )‐4‐(3,4‐dihydroxy‐6‐{(2 S ,4 R ,6 S )‐4‐[2‐(4‐hydroxy‐3‐methoxyphenyl)ethyl]‐6‐pentyl[1,3]dioxan‐2‐yl}‐2‐methylbenzyl)‐4,5‐dihydro‐5,5‐dimethylfuran‐2(3 H )‐one; 3 ), respectively, have been isolated from the roots of Lycianthes marlipoensis , and their structures were established by spectroscopic methods.
