Hexanic extracts from leaves and fruits of Schinus molle were tested for repellent and insecticidal properties against first instar nymphs and eggs of Triatoma infestans, the vector of Chagas' disease. Leaf and fruit extracts were highly repellent for first nymphs. Fruit extracts had also ovicidal activity.

Fasciolosis is a widespread parasitosis of farm live-stock in many developing countries. For this reason, it is necessary to search for new substances against parasitic diseases caused by flukes. Indeed, a wide variety of terrestrial plants have been subjected to chemical and pharmacological screening in order to discover their potential for human medicinal use. The molluscicidal and larvicidal...

AIM The antioxidant and pharmacological effects of hawthorn have mainly been attributed to the polyphenolic contents. The aim of this research is to determine some bioactive compounds and antioxidant properties of hawthorn aqueous and ethanol extracts of leaves, flowers, and ripened fruits. MATERIALS AND METHODS For this purpose, antioxidant activities of extracts were assessed on DPPH•, ABTS...

The effect of different extracts of leaves and fruits of Moringa oleifera Lam. (Moringaceae) on gastric and duodenal ulcers was evaluated by using different gastric ulcer models and cysteamine-induced duodenal ulcer method. The leaf extracts (500mg=kg, p.o.) of Moringa oleifera showed gastric ulcer healing effect in acetic acid–induced chronic gastric ulcers. The acetone extract and methanol ex...

Analytical HPTLC analysis of ethanolic extracts of leaf and fruits of Momordica tuberosa and Momordica dioica (Cucurbitaceae) showed the presence of charantin with Rf value 0.31at 536nm. Maximum amount of Charantin was found in the leaves of M. dioica than the fruits. Comparatively less amount of charantin was detected in the leaves and fruits of M. tuberosa Apart from charantin other saponins ...

The study was undertaken to assess the dosage-mortality ratio and toxic effects of Piper guineense fruit extracts on the adults of Biomphalaria pfeifferi, the snail intermediate host of Schistosoma mansoni, which causes intestinal schistosomiasis. The result showed significant toxic effects with crude ethanol and hot water fruits extracts. The estimated lethal dose concentration by arithmetic m...

"Greek-style" Moroccan black table olives were screened for potent odorants by GC/olfactometry/aroma extract dilution analysis of representative Likens-Nickerson extracts and compared with "Spanish-style" green fruits. ( Z)-3-Hexenal, ( E, E)-2,4-decadienal, ( E, Z)-2,4-decadienal, guaiacol, and methional were found in both green and black olives, but with significant differences in concentrati...

The present investigation was to evaluate the potential trypanocidal activity of crude ethanolic extract of the fruits of Solanum palinacanthum, Solanum lycocarpum and the glycoalcaloid, solamargine. S. palinacanthum and S. lycocarpum fruit powders were submitted to exhaustively extraction with 96% ethanol and solamargine were isolated from the extract of S. palinacanthum. Both extracts and sol...

It has been reported that latex and extracts of different species of Ficus are cytotoxic to some human cancerous cell lines. In this study, cytotoxicity of fruit and leaf extracts as well as the latex of Ficus carica L. on HeLa cell line were evaluated. Ethanolic extracts of leaves and fruits were prepared through percolation and ethyl acetate and dichloromethane extracts were prepared by reflu...
