ABSTRACT
Our aim was to evaluate the hypothesis in a randomized clinical trial, whether extra- corporeal lithotripsy [ESWL] causes any blood pressure change, in subjects with different genders having normal blood pressure and kidney lithiasis. A descriptive cross sectional study. This study was carried out at the Department of lithotripsy, Khan Kidney Hospital and King Edward Medical University, Lahore from February 2012 to January 2013. Adult patients [
ABSTRACT
Six compounds have been isolated from the leaves of Pyrenacantha staudtii,two of which are new compounds.The new compounds have been characterized as kaempherol 3-O-β-rhamnopyranosyl (1→6)β-D-glucopyranoside (1) and 4-β-glucopyranosyl-(2-furyl)-5-methy-1,2-glucopyranoside phenylmethanone (2).The known compounds are 3-pyridinecarboxylic acid (3),β-sitosterol (4),sitosterol 3-O-β-glucopyranoside (5) and taraxerol (6).Their structures were determined by spectroscopic and chemical evidences.The two new compounds together with 3-pyridinecarboxylic acid showed significant in vitro xanthine oxidase inhibitory activity.To the best of our knowledge,this is the first report of these compounds from this plant.
ABSTRACT
Six compounds have been isolated from the leaves of Pyrenacantha staudtii, two of which are new compounds. The new compounds have been characterized as kaempherol 3-O-beta-rhamnopyranosyl (1-->6)-beta-D-glucopyranoside (1) and 4-beta-glucopyranosyl-(2-furyl)-5-methy-1,2-glucopyranoside phenylmethanone (2). The known compounds are 3-pyridinecarboxylic acid (3), beta-sitosterol (4), sitosterol 3-O-beta-glucopyranoside (5) and taraxerol (6). Their structures were determined by spectroscopic and chemical evidences. The two new compounds together with 3-pyridinecarboxylic acid showed significant in vitro xanthine oxidase inhibitory activity. To the best of our knowledge, this is the first report of these compounds from this plant.
