nuezhenide/イボタノキ属

Methanol and hot-water extracts of glossy privet (Ligustrum lucidum Ait.) inhibited the mutagenic activity of benzo[a]pyrene in Salmonella typhimurium TA98 with S9 mix. The methanol extract was fractionated with ether and n-hexane. As the active components, oleanolic and ursolic acids were isolated,

Two new secoiridoid glucosides, namely iso-oleonuezhenide (1) and methyloleoside 7-ethyl ester (2), along with five known ones, oleonuezhenide (3), nuezhenide (4), oleuropein (5), G13 (6), and jaspolyside methyl ester (7), were isolated from the fruits of Ligustrum lucidum. Their structures were

The ethanol extract of the fruits of Ligustrum lucidum was shown to have inhibitory effects on the hemolysis of red blood cells induced by 2,2'-azo-bis-(2-amidinopropane) dihydrochloride. Bioassay-guided analysis led to the isolation of ten secoiridoid glucosides. Two of them were new, lucidumosides

A new secoiridoid glycoside characterized as (8 Z)-nuezhenide A along with five known glycosides, (8 E)-nuezhenide, (8 Z)-nuezhenide, oleonuezhenide, osmanthuside B and osmanthuside D, were isolated from the n-BuOH fraction of Ligustrum japonicum leaves. All six compounds significantly protected

Two secoiridoid glucosides, lucidumosides A and B, as well as six known glucosides, oleoside dimethyl ester, ligustroside, oleuropein, nuezhenide, isonuezhenide, and neonuezhenide, were isolated from the fruits of Ligustrum lucidum. Their structures were elucidated by spectroscopic methods.
