Comparative lipid and uric acid suppressing properties of four common herbs in high fat-induced obese mice with their total phenolic and flavonoid index

Abstract

Our present study was designed to investigate the comparative anti-obesity efficacy of ethanolic extract of Azadirachta indica A. Juss. , Trigonella foenum-graecum L. , Allium sativum L. and Zingiber officinale Roscoe in high fat-induced mice with their total phenolic and flavonoid profile. Total phenolic and flavonoid content were determined by Folin–Ciocalteu's and Aluminium chloride UV method respectively. In our study, 55 healthy mice were separated into 11 groups to take their respective treatments. Lipid and uric acid profile were estimated by using the enzymatic colourimetric method. Ethanolic extract of A. indica contained the highest phenolic and flavonoid content. A. indica normal and high fat diet group showed reduced weight gaining tendency than other extract groups. A. indica at a dose of 400 mg/kg body weight significantly (p < 0.001) reduced serum cholesterol (SC), triglyceride (TG), and uric acid (UA) level than other three extracts when compared with the control group. Thus, a considerable correlation was found between serum uric acid reducing potentials of the present experimental extracts with a lipid-lowering profile. Pathological examination revealed that the average weight of liver and kidney were significantly decreased in A. indica normal. Results obtained from the present study it can be concluded that ethanolic extract of A. indica possesses better lipid-lowering efficacy than the other three herbs.

A comparative evaluation of cardiac and neurological safety status of two commonly used oral hypoglycaemic agents in T2-DM Swiss albino mice model

“…These reagents were manufactured by the standard company Human Diagnostics Worldwide, Germany. TC was determined by an enzymatic colorimetric method (endpoint) [ 15 ], and TG was estimated by the enzymatic colorimetric GPO-PAP method [ 16 ]. HDL-C was measured by phosphotungstate method [ 17 ] by using Mindray BA-88A Semi-Auto Clinical Chemistry Analyzer (Crown Healthcare, Tanzania).…”

Promising bioactive properties of quercetin for potential food applications and health benefits: A review

“…The normal range of uric acid in blood is 360 and 420 μM in women and men, respectively, but close to neutral pH, such as in case of blood, concentrations >360 μM can initiate precipitation that leads to the accumulation of monosodium urate crystals in joint tissue interstitial spaces and gout ( 26 ). Increase in serum uric acid level causes weight gain thus leads to obesity which causes increase in uric acid synthesis and hinder its excretion via kidneys thus causing expansion in hyperuricemia ( 27 ). Liquid chromatography, bi-enzymatic colorimetry, capillary electrophoresis, and fluorescence spectroscopy are just a few of the systematic methods that have been developed to detect uric acid range in blood serum and urine of humans.…”

Study on the interaction mechanism between luteoloside and xanthine oxidase by multi‐spectroscopic and molecular docking methods

“…12,13 Due to the anti-inflammatory and antioxidant capacity of flavonoids, 14,15 studies have shown that flavonoids can affect the activity of XO, treat gout from the root and reduce the synthesis of uric acid. 7,16 Therefore, flavonoids have become a research hotspot for alleviating uric acid. 1 Some flavonoids, such as luteolin and apigenin, have promising therapeutic effects on gout.…”

“…Flavonoids widely exist in fruits, vegetables, and other foods in daily life 12,13 . Due to the anti‐inflammatory and antioxidant capacity of flavonoids, 14,15 studies have shown that flavonoids can affect the activity of XO, treat gout from the root and reduce the synthesis of uric acid 7,16 . Therefore, flavonoids have become a research hotspot for alleviating uric acid 1 .…”
