Two new chlorophenyl glycosides from the bulbs ofLilium browniivar.viridulum
摘要:
Two rare new chlorophenyl glycosides, 2,4,6-trichlorol-3-methyl-5-methoxy-phenol 1-O-beta-D-glucopyranosyl-(1 -> 6)-beta-D-glucopyranoside (1) and 4-chlorol-5-hydroxyl-3-methyl-phenol 1-O-alpha-L-rhamnopyranosyl-(1 -> 6)-beta-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.

Organochlorine Compounds from a Terrestrial Higher Plant: Structures and Origin of Chlorinated Orcinol Derivatives from Diseased Bulbs of <i>Lilium </i><i>maximowiczii</i>
maximowiczii, and their structures have been elucidated. Six of the chlorinated orcinol derivatives (2, 4-8) showed antifungal activity. Because organochlorine compounds are rare in terrestrial higher plants, their biosynthetic origin was examined. These compounds were shown to be induced in intact bulb scales by UV irradiation or by inoculation with the pathogenic fungus Fusarium oxysporum f. sp. lilii. Biosynthetic
