| antioxidant properties and phytochemical characteristics of extracts from lactuca indica. | lactuca indica (compositae) is an edible wild vegetable, used as a folk medicine in anti-inflammatory, antibacterial, and other medications in asia. this is the first scientific evaluation of the chemopreventive therapeutic properties of l. indica using five antioxidation assay systems. an extract from l. indica was found to possess significant free radical scavenging activity, effectively protecting phix174 supercoiled dna against strand cleavage and reducing oxidative stress in human promyeloc ... | 2003 | 12590506 |
| antidiabetic dimeric guianolides and a lignan glycoside from lactuca indica. | three novel sesquiterpene lactones, lactucain a (1), b (2), and c (3), and a new furofuran lignan, lactucaside (4), were isolated from lactuca indica along with nine known compounds, 11beta,13-dihydrolactucin, cichoriosides b, quercetin, quercetin 3-o-glucoside, rutin, apigenin, luteolin, luteolin 7-o-glucuronide, and chlorogenic acid. among these compounds, latucain c (3) and lactucaside (4) showed significant antidiabetic activity. | 2003 | 12762795 |
| induction of apoptosis by the lactuca indica l. in human leukemia cell line and its active components. | lactuca indica l. (compositae family) is used as a folk medicine in anti-inflammatory, antibacterial, antidiabetic, and other medications in asia. the objectives of this study were to evaluate the antiproliferative effect of ethanol extracts of lactuca indica l. (eel) on human leukemic hl-60 cell lines and its active components. the results showed that eel exhibited strong cytotoxic effects against hl-60 cells; the ic50 value was 313 microg/ml. flow cytometric analysis of the externalization of ... | 2007 | 17295517 |
| isolation of quinic acid derivatives and flavonoids from the aerial parts of lactuca indica l. and their hepatoprotective activity in vitro. | in our continuing study of biologically active compounds from korean medicinal plants, we investigated the hepatoprotective constituents of the aerial parts of lactuca indica l. (compositae), since the methanolic extract of l. indica has hepatoprotective activity against hepatitis b virus (hbv) production. the bioactivity-guided separation of the methanolic extract of the aerial parts of l. indica resulted in the isolation of seven quinic acid derivatives (1, 3-4, 6, and 10-12), along with five ... | 2007 | 18029179 |
| terpene and phenolic constituents of lactuca indica l. | we isolated seven terpenes and five phenolic constituents from the aerial parts of lactuca indica l. using column chromatographic separation of its meoh extract. their structures were determined by spectroscopic methods to be trans-phytol (1), 3beta-hydroxyglutin-5-ene (2), 5,6-epoxy-3-hydroxy-7-megastigmen-9-one (3), 11beta-13-dihydrolactucin (4), 2-phenylethyl beta-d-glucopyranoside (5), cichorioside b (6), 1-hydroxylinaloyl-6-o-beta-d-glucopyranoside (7), (6s,9s)-roseoside (8), benzyl-beta-d- ... | 2008 | 18787785 |
| lactuca indica extract interferes with uroepithelial infection by escherichia coli. | uropathogenic escherichia coli is the major cause for urinary tract infections (uti). due to emerging antimicrobial resistances treatment of uti is becoming increasingly difficult. therefore, alternative treatment strategies are required. we sought to investigate the molecular mechanisms of a traditionally used decoction from vietnamese dandelion (lactuca indica l.) mediating local protection of the bladder epithelium. | 2011 | 21497191 |
| antioxidant activity in extracts of 27 indigenous taiwanese vegetables. | the objectives of this study were to identify the antioxidants and antioxidant axtivity in 27 of taiwan's indigenous vegetables. lycium chinense (lc), lactuca indica (li), and perilla ocymoides (po) contained abundant quercetin (que), while artemisia lactiflora (al) and gynura bicolor (gb) were rich in morin and kaempferol, respectively. additionally, nymphoides cristata (nc) and sechium edule (se)-yellow had significantly higher levels of myricetin (myr) than other tested samples. cyanidin (cya ... | 2014 | 24858497 |
| nutrients value and antioxidant content of indigenous vegetables from southern thailand. | evidence from epidemiological studies has strongly suggested that diets rich in fruits and vegetables play a vital role in disease prevention. the aim of this study was to determine nutrient and antioxidant content for 15 varieties of indigenous vegetables and fruits collected from southern thailand. the data indicated that indigenous vegetables provided small to moderate amounts of macronutrients and minerals. the highest content of β-carotene was found in indian lettuce (lactuca indica; 3575.5 ... | 2015 | 25466097 |
