Phytochemical screening, mineral analysis and evaluation of the diuretic effect of aqueous extract of Pericopsis laxiflora from male Sprague Dawley rats
Abstract
Pericopsis laxiflora is among the medicinal plants used by the traditional practitioner in the treatment of many diseases. However, data on its diuretic power are lacking. Moreover, the effect of the preparation of traditional galenic formulations on the composition of phytocompounds and essential minerals and metals is unknown. The aim of this study was to show the effect of treatment on the phytocompounds and minerals composition and to evaluate diuretic effect of Pericopsis laxiflora aqueous axtracts. The tube characterization reactions revealed flavonoids, sterols, terpenes, catechin tannins polyphenols and saponins in aqueous extracts. Gallic tannins and quinones are absent, All compounds were generally present in same proportions in two aqueous extracts. Chemical analysis of all aqueous extracts by atomic absorption spectrometry (AAS) showed effect of model extraction on minerals. Copper (0.3116 mg / 100g), magnesium (260.7 mg /100 g), selenium (0.00904 mg /100 g), zinc (4.52 mg /100 g), manganese (75.029 mg /100g) are more concentrated in maceration than a decoction. For decoction of same plant, the situation is reversed with sodium (58.6mg /100g), calcium (12670 mg/100g), iron (18.51mg/100g) and potassium (2781 mg /100g). For pharmacological investigation, 32 rats Sprague Dawley male weighing 385-433g are isolated each in metabolic cages from 6 pm to 8am and treated with 100mg/kg of Pericopsis laxiflora aqueous extracts. From 8am to 2pm the animals received only tap water in metabolic cages. The volumes of water intake and urine were not significantly different in the two groups (treated and untreated).The diuretic effect was not observed with 100mg/kg (b/w) . In addition polyphenols, flavonoids, saponins and minerals such as potassium, magnesium and selenium are indicators of the vasodilatory and cardioprotective functions of Pericopis laxiflora aqueous extracts. The prescription of these extracts in traditional medicine must take into account the toxicity of the plant associated with a calcium and manganese content.
