Two new chlorophenyl glycosides from the bulbs of Lilium brownii var. viridulum

Two rare new chlorophenyl glycosides, 2,4,6-trichlorol-3-methyl-5-methoxy-phenol 1-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside (1) and 4-chlorol-5-hydroxyl-3-methyl-phenol 1-O-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside (2), along with three known compounds (3-5) were isolated from the bulbs of Lilium brownii var. viridulum. The structures of the new compounds were elucidated on the basis of spectroscopic and chemical methods. All the compounds exhibited weak inhibition of NO production in LPS-stimulated RAW 264.7 cells.
