| [preliminary study on pharmacologic action of ligustrum japonicum]. | the results of treatment with the ligustrum japonicum thunb. var. pubescens koidz (lj) in rabbits' model of hyperlipemia and atherosclerosis was observed. the results showed: (1) by the end of first to third month, the levels of serum tl and tc in groups b,c were lower than that of group a and there was significant difference between them (p < 0.05), the level of serum tg in groups b,c was lower than that of group a too, but there was no significant difference between them (p > 0.05). (2) by the ... | 1994 | 7703637 |
| screening for antioxidant activity in edible plant products: comparison of low-density lipoprotein oxidation assay, dpph radical scavenging assay, and folin-ciocalteu assay. | oxidation of low-density lipoprotein (ldl) has been implicated in atherogenesis. antioxidants that prevent ldl from oxidizing may reduce atherosclerosis. this study investigated ldl antioxidant activity in edible plant products for development of dietary supplementation to prevent atherosclerosis. fifty-two kinds of edible plants were extracted using 70% aqueous ethanol solution, and the antioxidant activity of the extracts, which inhibit human ldl oxidation induced by copper ion, was determined ... | 2004 | 15080652 |
| a new neuroprotective compound of ligustrum japonicum leaves. | 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 human neuroblastoma sh-sy5y cells from 6-hydroxydopamine-induced neurotoxicity. | 2006 | 16450298 |
| seasonal variations in water relations in current-year leaves of evergreen trees with delayed greening. | we investigated seasonal patterns of water relations in current-year leaves of three evergreen broad-leaved trees (ilex pedunculosa miq., ligustrum japonicum thunb., and eurya japonica thunb.) with delayed greening in a warm-temperate forest in japan. we used the pressure-volume method to: (1) assess the extent to which seasonal variation in leaf water relations is attributable to leaf development processes in delayed greening leaves versus seasonal variation in environmental variables; and (2) ... | 2006 | 16651252 |
| mortality of atta sexdens rubropilosa (hymenoptera: formicidae) workers in contact with colony waste from different plant sources. | the objective of this work was to study the effect of colony waste on the mortality of workers of atta sexdens rubropilosa forel colonies fed with different plant substrates. eight nests were used; two colonies each were fed with acalypha wilkesiana müller.arg, ligustrum japonicum thunb, eucalyptus urophylla s.t. blake or a mixture of the three substrates in equal proportions. irrespective of diet, being kept with waste led to higher mortality. however, workers that were kept in contact with was ... | 2010 | 19366474 |
| isolation of antifungal compounds from gardenia jasminoides. | gardenia jasminoides e. (rubiaceae) methanol extracts showed the highest level of antifungal activity against pleurotus ostreatus, a wood-rotting fungus, compared to five other methanol plants extracts; [thuja orientalis l. (cupressaceae), datura innoxia (solanaceae), ligustrum japonicum t. (oleaceae), juniperus chinensis var. procumbens (cupressaceae) and mallotus japonica m. (euphorbiaceae)] and selected for further analysis. two antifungal compounds were isolated from n-butanol and ethyl acet ... | 2009 | 19817121 |
| a novel ilarvirus is associated with privet necrotic ringspot disease in the southern united states. | necrotic ringspot disease (nrsd) is a graft-transmissible disorder of privet (synonym ligustrum), originally reported from florida and louisiana more than 50 years ago. in this communication we report an isometric virus isolated from japanese privet (ligustrum japonicum) collected in the southern united states displaying symptoms resembling those of nrsd. in mechanical transmission tests, the virus induced systemic infections in several herbaceous hosts. double-stranded rna analysis showed a pat ... | 2016 | 26390186 |
| identification and characterization of privet leaf blotch-associated virus, a novel idaeovirus. | a novel virus has been identified by next-generation sequencing (ngs) in privet (ligustrum japonicum l.) affected by a graft-transmissible disease characterized by leaf blotch symptoms resembling infectious variegation, a virus-like privet disease with an unclear aetiology. this virus, which has been tentatively named 'privet leaf blotch-associated virus' (prlbav), was absent in non-symptomatic privet plants, as revealed by ngs and reverse transcription-polymerase chain reaction (rt-pcr). molecu ... | 2016 | 27349357 |
| [bioindication of environmental quality based on plant mutational and modification variability]. | the level of mutations (aberrations of chromosomes, gene mutations) and modifications (bilateral asymmetry of the leaves) induced with ng (n-methyl-n-nitro-n-nitro-zoguanidine) and granozane, as well as with environmental pollutants have been studied on vicia faba, triticum aestivum, arabidopsis thaliana, ligustrum japonicum, olea europea. the tested xenobiotic increased the level of mutations and modifications. the bilateral asymmetry is suggested as a test for environmental quality assessment. | 2009 | 19938627 |
| characteristics of green-blue fluorescence generated from the adaxial sides of leaves of tree species. | we discovered that some tree species have leaves whose adaxial sides show bright green-blue fluorescence upon exposure to ultraviolet irradiation. in total, 141 native japanese species belonging to 47 families were analyzed, and the brightness of the leaf fluorescence, represented by the l* values (lab color space) of the pictures, was evaluated. the species possessing the brightest fluorescent leaves, with l* > 50, were camellia japonica, camellia sasanqua, and cleyera japonica of theaceae, osm ... | 2017 | 28091760 |
| involvement of acetaldehyde in seed deterioration of some recalcitrant woody species through the acceleration of aerobic respiration. | the rate of acetaldehyde (ald) evolution in the deterioration of recalcitrant woody seeds was investigated. four plant species, ligustrum japonicum, quercus serrata, quercus myrsinaefolia and camellia japonica, were used for the experiments. similar to orthodox seeds, all of the recalcitrant seeds used contained ald in addition to methanol and ethanol, although the amount of ald in camellia, a typical oil seed, was very small. these volatiles were accumulated in a container in which ligustrum an ... | 2004 | 14988490 |
