Rheedia longifolia Planch et Triana belongs to the Clusiaceae family. This plant is widely distributed in Brazil, but its chemical and pharmacological properties have not yet been studied. We report here that leaves aqueous extract of R. longifolia (LAE) shows analgesic and anti-inflammatory effects. Oral or intraperitoneal administration of this extract dose-dependently inhibited the abdominal...

OBJECTIVE To evaluate methanolic, ethanolic, acetone and aqueous extracts from different parts of Eurycoma longifolia (E. longifolia) (leave, stem, and root) for antibacterial activity against Gram-positive and Gram-negative bacteria and to utilize the leaves and stem parts rather than the root, which is already used for male sexual enhancement in Malaysia. METHODS The study took place in the...

Eurycoma longifolia Jack. is a treelet that grows in the forests of Southeast Asia and is widely used throughout the region because of its reported medicinal properties. Widespread harvesting of wild-grown trees has led to rapid thinning of natural populations, causing a potential decrease in genetic diversity among E. longifolia. Suitable genetic markers would be very useful for propagation an...

In salt-tolerant Chara longifolia, enhanced Na+ efflux plays an important role in maintaining low cytoplasmic Na+. When it is cultured in fresh water (FW), C. longifolia has a higher Na+ efflux than the obligate FW Chara corallina, although pH dependence and inhibitor profiles are similar for both species (1. Whittington and M.A. Bisson 119941 j Exp Bot 45: 657-665). When it is cultured in salt...

Eurycoma longifolia is reputed as an aphrodisiac and remedy for decreased male libido. A randomized, double-blind, placebo controlled, parallel group study was carried out to investigate the clinical evidence of E. longifolia in men. The 12-week study in 109 men between 30 and 55 years of age consisted of either treatment of 300 mg of water extract of E. longifolia (Physta) or placebo. Primary ...

Chloroform extract of the leaves of Asteracantha longifolia at different doses (250 and 500 mg/kg body weight) was examined on anaemic albino rat for certain haematological parameters like erythrocyte count, leukocyte count, and haemoglobin count. Chloroform extract was found to significantly (P<0.05) improve erythrocyte and haemoglobin count on the 22 day (d) after 7 d of continuous cyclophosp...

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed and cross-species transferability assessed for two Persoonia species to evaluate genetic diversity and population genetic structure of these broadly distributed southwest Australian tree species. • METHODS AND RESULTS Microsatellite-enriched libraries and 454 GS-FLX shotgun sequencing were used to identity nine microsate...

The essential oil composition from the aerial parts of three Anacardiaceae growing in Bahía Blanca, Argentina was studied by gas chromatography and gas chromatography-mass spectrometry. The essential oils of S. longifolia and S. fasciculata have been studied for the first time. The major constituents were alpha-pinene (46.5%), beta-pinene (15.1%) and alpha-phellandrene (10.1%) for S. longifolia...

Tephroseris longifolia agg. is a complex group of outcrossing perennials distributed throughout Central Europe. Recent morphological study revealed six morphotypes corresponding to five previously distinguished subspecies, together with Alpine and Pannonian morphotypes of T. longifolia subsp. longifolia. The delimited morphotypes differ in relative DNA content, geographical range, and rarity. W...

Objective: The aim of this study was to evaluate the inhibitory effect of E. longifolia extract on five human cytochrome P450 isoforms. Methods: The inhibitory effect of E. longifolia standardized extract (TAF-273) on five human cytochrome P450 isoforms, namely CYP1A2, CYP3A4, CYP2C9, CYP2C19 and CYP2D6, was determined using a luminescence method. The effect of eurycomanone on cytochrome P450 i...
