Diuretic Activity of Methanol Extracts of Rubus idaeus L.

Abstract

The purpose of this article is to evaluate the diuretic potential of Rubus idaeus L. fruits. By measuring the urine volume of experimental animals, we find that methanol extract of Rubus idaeus L. fruits significantly increased the urine volume of experimental animals suggesting its diuretic effect. This is the first formal report on the diuretic activity of Rubus idaeus L. fruits. Moreover, four fractions isolated from the methanol extract were further studied and the results showed that ethyl acetate fraction (RIEA) has a direct relationship with the diuretic activity of Rubus idaeus L. fruits. The urinary electrolyte patterns of experimental animals were also analyzed, we find that Rubus idaeus L. fruits have an effect on the conservation of potassium, which is an interesting property in a phyto-diuretic.www.ccsenet.org/ijb

Study on diuretic activity of saffron (stigma of Crocus sativus L.) Aqueous extract in rat

“…Ying Zhang et al .,[ 17 ] compared diuretic activity of Rubusidaeus L. extracts with hydrochlorothiazide (synthetic diuretic) in rat. They showed that hydrochlorothiazide had a higher inhibitory effect on electrolyte (Na + , K + and Cl - ) in rats than the extracts, nevertheless their abilities for inhibiting the UV were similar with our results in the present study.…”

Effect of Maturity Stage and Storage on Flavor Compounds and Sensory Description of Berrycactus (Myrtillocactus geometrizans)

“…Dichloromethane is a common solvent used in volatile analysis. Methanol was selected in order to evaluate this solvent as a new option for aroma studies; it was previously used by Zhang and others (2011), Hannus and others (2006), and Sule and others (2005). By means of chromatograms comparison between dichloromethane and methanol extracts, methanol extract had a major quantity of volatile compounds.…”
