insecticidal, acaricidal and synergistic effects of soosan, pancratium maritimum extracts and constituents. | in assessing the pesticidal activity of soosan, p. maritimum, the bulbs and leaves were extracted using acetone/ethanol & ethanol as solvents and mosquito larvae c. pipiens, as a test organism. the actone/ethanol extract of bulbs was more toxic (lc50: 25 ppm) than that of the leaves (lc50: 75 ppm). crude alkaloids, lycorine, terpenes & sterols and fixed oil were isolated from soosan bulb. their percentages were: 0.193, 0.02, 0.13 and 3.3%, respectively. the acetone/ethanol extract showed a stron ... | 1998 | 9617056 |
antimalarial activity screening of some alkaloids and the plant extracts from amaryllidaceae. | four groups of amaryllidaceae alkaloids, namely lycorine-, crinine-, tazettine-, and galanthamine-type, as well as plant extracts of the amaryllidaceae plants (pancratium maritimum, leucojum aestivum, and narcissus tazetta ssp. tazetta) growing in turkey were evaluated in vitro for their ability to inhibit plasmodium falciparum growth by a high-throughput screening method with a 96-well microtiter plate. all four groups of alkaloids exhibited antimalarial activity at different potencies. 6-hydro ... | 2003 | 14669261 |
differential regulation of photorespiratory gene expression by moderate and severe salt and drought stress in relation to oxidative stress. | the tolerant c3 plant pancratium maritimum l. was used to investigate the contribution of photorespiration to the oxidative load under salt and drought stress. 7-weeks old plants were salt-stressed by 150 or 300 mm nacl or drought-stressed by withholding water for 11 or 21 days. the growth, photosynthesis (a) and transpiration rates (e) were reduced by all stress treatments proportionally to the severity of stress. the rate of photorespiration was remarkably higher under moderate stresses than u ... | 2011 | 21421402 |
In vitro amoebicidal activity of ethanol extracts of Arachis hypogaea L., Curcuma longa L. and Pancratium maritimum L. on Acanthamoeba castellanii cysts. | Acanthamoeba castellanii causes amoebic keratitis which is a painful sight-threatening disease of the eyes. Its eradication is difficult because the amoebas encyst making it highly resistant to anti-amoebic drugs, but several medicinal plants have proven to be more effective than the usual therapy. This study aimed to evaluate the in vitro amoebicidal activity of ethanol extracts of Arachis hypogaea L. (peanut), Curcuma longa L. (turmeric), and Pancratium maritimum L. (sea daffodil) on A. castel ... | 2011 | 22146994 |
the generalist inside the specialist: gut bacterial communities of two insect species feeding on toxic plants are dominated by enterococcus sp. | some specialist insects feed on plants rich in secondary compounds, which pose a major selective pressure on both the phytophagous and the gut microbiota. however, microbial communities of toxic plant feeders are still poorly characterized. here, we show the bacterial communities of the gut of two specialized lepidoptera, hyles euphorbiae and brithys crini, which exclusively feed on latex-rich euphorbia sp. and alkaloid-rich pancratium maritimum, respectively. a metagenomic analysis based on hig ... | 2016 | 27446044 |
ungeremine and its hemisynthesized analogues as bactericides against flavobacterium columnare. | the gram-negative bacterium flavobacterium columnare is the cause of columnaris disease, which can occur in channel catfish ( ictalurus punctatus ). in a previous study, the betaine-type alkaloid ungeremine, 1, obtained from pancratium maritimum l. was found to have strong antibacterial activity against f. columnare. in this study, analogues of 1 were evaluated using a rapid bioassay for activity against f. columnare to determine if the analogues might provide greater antibacterial activity and ... | 2013 | 23331165 |
