jatrophone/jatropha

BACKGROUND Jatropha isabellei Müll. Arg. (Euphorbiaceae) has been used in the traditional medicine to treat arthritis. OBJECTIVE To evaluate the anti-inflammatory and antinociceptive activities of the dichloromethane fraction (DFJi) from underground parts of J. isabellei, and to develop an

1. Jatrophone (JAT), a diterpene isolated from the plant Jatropha elliptica (1-300 microM), caused a concentration-dependent relaxation effect against acetylcholine (Ach)-oxytocin (Ot)- and KCl-induced uterine sustained contraction. The relative potency order was: Ach greater than Ot greater than

A method for sample preparation and analysis by high performance liquid chromatography with UV detection (HPLC-UV) was developed for analysis of jatrophone in "cachaça" prepared with Jatropha elliptica, administered orally, employed in Brazil for the treatment of venomous snake bites. The linearity,

In the search for new molluscicidal natural products, the activity of the crude ethanol extract of the rhizome of Jatropha elliptica (Pohl.) Muell. Arg. was tested. The LC(50) was 13.07 ppm. The fractionation and purification of the extract furnished jatrophone and a mixture of jatropholones A and

Jatropha elliptica (Pohl) Oken (Euphorbiaceae) roots are used in folk medicine to treat gastric ulcers. The purpose of this work was to evaluate the gastroprotective activity of ethanol extract (JER) and hexane fraction (ERH) of J. elliptica roots in mice, as well as to analyze the acute toxicity of

This study addresses the in vitro culture as an alternative to obtain compounds with cytotoxic activity from the medicinal plant Jatropha curcas (Euphorbiaceae). We determined the presence of cytotoxic compounds in both whole plants and dedifferentiated cells. We evaluated the effect of auxin,

Glutamate is to be considered a nociceptive neurotransmitter and glutamatergic antagonists present antinoceptive activity. In this study we investigated the effects of the naturally occurring antinociceptive compounds rutin, geraniin and quercetine extracted from Phyllanthus, as well as the

Protozoal diseases such as malaria are a leading world health concern. We screened a library of fractionated natural products to identify new potential therapeutic leads and discovered that jatrophone (a product of Jatropha isabelli) exerts significant activity against Plasmodium falciparum strains

A new jatrophone derivative (6), jatrophone (3), jatropholone A (4) and jatropholone B (5), acetyl aleuritolic acid (1), cyperenoic acid (2) and a monoterpene were isolated from the rhizomes of the Paraguayan crude drug Jatropha isabelli. The compounds were characterized by spectroscopic means. The
