| phytochemical constituents and hepatoprotective activity of viburnum tinus. | from the leaves of viburnum tinus l. (adoxaceae) two acylated iridoid glucosides (viburtinoside a and b), a coumarin diglucoside scopoletin 7-o-beta-d-sophoroside and a natural occurred dinicotinic acid ester 2,6-di-c-methyl-nicotinic acid 3,5-diethyl ester were isolated. in addition to these, 10 known compounds were isolated, namely two bidesmosidic saponins, a hexamethoxy-flavone and five flavonol glycosides, as well as suspensolide a and oleanolic acid were isolated for the first time in this ... | 2005 | 16303155 |
| a test system to quantify inoculum in runoff from phytophthora ramorum-infected plant roots. | foliar hosts of phytophthora ramorum are often susceptible to root infection, but the epidemiological significance of such infections is unknown. a standardized test system was developed to quantify inoculum in runoff from root-infected viburnum tinus 'spring bouquet' or rhododendron 'cunningham's white' cuttings. cuttings of both species gave off a maximum amount of inoculum 1 to 3 weeks after inoculation. the greatest amount of inoculum was recovered from viburnum roots that were 48 to 70 days ... | 2011 | 21830955 |
| use of phytoremediated sediments dredged in maritime port as plant nursery growing media. | we evaluated the potential of a phytoremediated sediment (tr) dredged from maritime port as peat-free growth substrate for seven ornamental plants, in comparison with an untreated sediment (nt), in a greenhouse experiment. the studied plants were quercus ilex, photinia x fraseri, viburnum tinus, cistus albidus, raphiolepis indica, westringia fruticosa and teucrium fruticans. plant growth was monitored for ten months, and the changes in the physico-chemical properties, toxicity, microbial biomass ... | 2017 | 27307384 |
| activity, polypeptide and gene identification of thylakoid ndh complex in trees: potential physiological relevance of fluorescence assays. | three evergreen (laurus nobilis, viburnum tinus and thuja plicata) and two autumnal abscission deciduous trees (cydonia oblonga and prunus domestica) have been investigated for the presence (zymogram and immunodetection) and functionality (post-illumination chlorophyll fluorescence) of the thylakoid ndh complex. the presence of encoding ndh genes has also been investigated in t. plicata. western assays allowed tentative identification of zymogram nadh dehydrogenase bands corresponding to the ndh ... | 2012 | 22324908 |
| influence of arbuscular mycorrhizal fungi and treated wastewater on water relations and leaf structure alterations of viburnum tinus l. plants during both saline and recovery periods. | nowadays, irrigation with low quality water is becoming an alternative to satisfy the needs of crops. however, some plant species have to deal with high salinity of reclaimed water, by adapting their physiological behaviour during both saline and recovery periods and developing morphological changes in their leaves. the application of arbuscular mycorrhizal fungi (amf) could also be a suitable option to mitigate the negative effects of this kind of water, although the effectiveness of plant-amf ... | 2015 | 26476190 |
| α-glucosidase and lipoxygenase inhibitory derivatives of cryptosporioptide from the endophytic fungus cryptosporiopsis sp. | two new cryptosporioptide-derived polyketides cryptosporioptides a (2) and b (3) were isolated from the extract of endophytic fungus cryptosporiopsis sp. associated with the shrub, viburnum tinus. the structures of the isolates were determined through spectral analysis including 1d nmr ((1)h, (13)c) and 2d nmr (hsqc, hmbc, cosy) techniques, hr-fab-ms and by comparison with the reported data of cryptosporioptide (1). the relative stereochemistry was assigned with the help of noesy analysis, the m ... | 2014 | 25030552 |
