acyl-coa:cholesterol acyltransferase inhibitory activity of lignans isolated from schizandra, machilus and magnolia species.	fifteen lignans were isolated from the fruits of schizandra chinensis, the leaves of machilus thunbergii, and the flower buds of magnolia denudata. they were identified as gomisins, schizandrin, wuweizisu, schizantherin, licarins, and machilin, which inhibited rat liver acat with ic (50) values of 25-200 microm. comisin n is the most potent inhibitor with ic (50) value of 25 microm in these lignans.	1999	17260239
magnoliae flos induces apoptosis of rbl-2h3 cells via mitochondria and caspase.	magnoliae flores (mf), the buds of magnolia denudata desrousseaux, have been successfully used for the management of allergic diseases in korea. the purpose of the present study was to determine their causal role in inducing apoptosis of mast cells and to verify the underlying mechanism.	2003	12811018
[time lag characteristics of stem sap flow of common tree species during their growth season in beijing downtown].	from april to september in 2008, the stem sap flow velocity (js) of several common tree species (ginkgo biloba, aesculus chinensis, magnolia denudata, robinia pseudoacacia, pinus tabulaeformis and cedrus deodara) in beijing was measured by thermal dissipation method. crosscorrelation analysis was used to estimate the time lag between the stem sap flow and the driving factors of canopy transpiration among the tree species. the js of the six tree species was significantly correlated with the total ...	2009	20030130
cloning, expression and characterisation of a promising mosquitocidal gene.	a new mosquitocidal gene, cyt1aa6, was isolated and cloned from the novel bacillus thuringiensis strain llp29, previously isolated from the phylloplane of magnolia denudata. nucleotide sequence analysis of cyt1aa6 indicated that the open reading frame consisted of 750 base pairs, encoding 249 amino acid sequences with a calculated molecular weight of 27.3681 kda and a pi value of 4.77. an homological comparison revealed that the cyt1aa6 amino acid sequence was 99% identical with those of known c ...	2009	20112806
a novel mosquitocidal bacillus thuringiensis strain llp29 isolated from the phylloplane of magnolia denudata.	eleven bacillus thuringiensis isolates were recovered from phylloplanes of magnolia denudata, a specific source of new strains of b. thuringiensis. among these, a new strain, llp29, was found to be most toxic to mosquitoes based on the results of preliminary toxicity analysis. phase contrast microscopy, mosquitocidal activity, polymerase chain reaction (pcr) analysis and parasporal inclusion were performed to learn more about the characteristics of this novel mosquitocidal isolate. the lc(50) va ...	2010	19577911
effect of wood hardness and secondary compounds on feeding preference of odontotermes formosanus (isoptera: termitidae).	odontotermes formosanus (shiraki) (isoptera: termitidae) is one of the most destructive plant pests in china, which control relies mainly on baits strategies. baits made from the wood of eight different tree species were used to study the feeding preference of this termite, and conversely wood protection strategies of the tree species. three bait types were used to identify wood protection strategies: solid wood (physical and chemical protection), crude flour (chemical protection) made from grou ...	2011	21735905
[effect of different host plants on the volatile components in taxillus sutchuenensis].	to study the effect of different host plants on the volatile somponents in taxillus sutchuenensis.	2013	24417148
antioxidative and anticanceric activities of magnolia (magnolia denudata) flower petal extract fermented by pediococcus acidilactici kccm 11614.	in this study, the effects of magnolia (magnolia (m.) denudata) extract fermentation in increasing the extract's antioxidative and anticancer activities were investigated. magnolia was fermented by pediococcus acidilactici kccm 11614. the total phenolic content was determined by the folin-ciocalteu's method and the antioxidative effects by 1,1-diphenyl-2-picrylhydrazy (dpph) and ferric reducing ability of plasma (frap) assay. anticancer activity against cancer and normal cells was determined usi ...	2015	26151113
larvicidal activity of magnolia denudata seed hydrodistillate constituents and related compounds and liquid formulations towards two susceptible and two wild mosquito species.	anopheles sinensis, aedes aegypti and aedes albopictus and culex pipiens pallens mosquitoes transmit malaria, dengue fever and west nile virus diseases respectively. this study was conducted to determine the toxicity of 17 constituents from magnolia denudata seed hydrodistillate (md-shd) and four experimental md-shd liquid formulations (10-50 mg l(-1) liquid) to third-instar larvae from insecticide-susceptible cx. p. pallens and ae. aegypti as well as wild ae. albopictus and an. sinensis.	2016	26085316
pollution resistance assessment of existing landscape plants on beijing streets based on air pollution tolerance index method.	various plant species of green belt in urban traffic area help to reduce air pollution and beautify the city environment. those plant species growing healthily under long-term atmospheric pollution environment are considered to be resilient. this study aims to identify plant species that are more tolerant to air pollution from traffic and to give recommendations for future green belt development in urban areas. leaf samples of 47 plant species were collected from two heavy traffic roadside sites ...	2016	27326901
