| antitumor and antibacterial activity of ethylacetate extract of ludwigia hyssopifolia linn and its active principle piperine. | an alkaloid constituent 1-[5-(1,3-benzodioxol-5-yl)-1-oxo-2,4-pentadienyl]piperidine, trivial name piperine was isolated from ludwigia hyssopifolia linn. (family-onagraceae). the ethylacetate extract of the plant and the isolated compound piperine were studied for antitumor and in vitro antibacterial activity. ethylacetate extract showed 73.05 and 84.14% inhibition of agrobacterium tumefaciens-induced crown gall tumor formation in potato disc. piperine exhibited antitumor activity with ic50 valu ... | 2007 | 17416568 |
| antidiarrheal activity of the methanol extract of ludwigia hyssopifolia linn. | dried whole plant parts of ludwigia hyssopifolia were subjected to successive cold extraction with n-hexane, ethylacetate and methanol. the methanol extract (lhm), obtained as 1% yield, showed significant antidiarrheal property by reducing diarrheal episodes in castor oil and serotonin induced diarrhea in laboratory mice at a dose of higher than 100 mg/kg body weight as compared to standard drug loperamide given at a dose of 66.67 microg/kg body weight. the percent reduction in diarrheal episode ... | 2003 | 16414562 |
