OBJECTIVES There are a few previously reported studies about the effect of Nigella sativa oil on renal ischemia-reperfusion injury (IRI). The aim of the present study was to test the hypothesis whether pre- or post-treatment with N. sativa hydroalcoholic extract (NSE) would reduce tissue injury and oxidative damages in a clinically relevant rat model of renal IRI. MATERIALS AND METHODS IRI wa...

Essential oils from fresh leaves, flowers and dried fruits of Vitex negundo were obtained by hydrodistillation. Using Soxhlet extractor five successive extracts from dried and powdered leaves were also taken. The chemical constituents of essential oil of leaves, flowers and dried fruits were analyzed by GC-FID and GC/MS techniques. Main constituents identified in leaves oil were delta-guaiene, ...

Soxhlet extractor was used in the extraction of oil from milled seeds of Terminalia catappa using petroleum ether (40-60 degrees ). The optimal oil yield was 56.71+/-1.66% with a viscosity of 40.79+/-1.05 centipoises. Other parameters of the oil were found as follows; specific gravity-0.9248, refractive index-1.4646, acid value-3.35, peroxide value-8.6, saponification value-166.2, and unsaponif...

Solid wastes from agro-industries may be used as culture medium for enzymes synthesis by filamentous fungi. The brewer’s spent grain (BSG) is generated in abundance in the south of Brazil. Currently, most of this waste is used for animal feed. This work aims to extract and quantify the lipid presents in this residue. The lipids extraction was carried out by Soxhlet extraction method. Initially,...

Seven cane brown sugars (four from La Réunion, two from Mauritius, and one from France) were investigated for their polyphenol content and volatile composition in relation to their free radical scavenging capacity determined by ABTS and DPPH assays. The thin layer coated on the sugar crystal was extracted by Soxhlet extractor with dichloromethane. The volatile compounds of brown sugars were stu...

OBJECTIVE(S) The ongoing increasing antibiotic resistance is one of the biggest challenges faced by global public health. The perennial need for new antimicrobials against a background of increasing antibiotic resistance in pathogenic and opportunistic microorganisms obliges the scientific community to constantly develop new drugs and antimicrobial agents. Lichens are known prolific sources of ...

THE investigations of Williams and Trvinel showed that extraction of organic material from bone with ethylenediamine (ED) was superior to ashing with KOH-glycol. Since the anorganic skeleton prepared in the former manner appeared to be intact, the method was utilized by them in studies of trabecular stress patterns. They also noted that less alteration of crystalline structure resulted from pre...

INTRODUCTION Seeking better quality of life, the number of studies on functional foods and disease prevention is growing fast. Whole red grape juice (WRGJ) and red wine (RW) stand out, which are rich in polyphenols, showing antioxidant and anti-inflammatory activity. OBJECTIVE To evaluate the effect of WRGJ and RW intake and resveratrol solution (RS) on blood pressure and fat liver deposition...

Acid mine drainage is the result of the oxidation process of sulfide bearing rocks. This process occurs when the sulfide material is exposed to atmospheric conditions. Under these conditions, successive oxidation reactions yield sulfuric acid generating acidic waters. This problem becomes more serious when the surrounding rocks are not able to neutralize the acid. The low pH condition of the dr...

Many traditional plant treatments for diabetes mellitus are used throughout the world and few of the traditional plant treatments for diabetes have been shifted scientific scrutiny. The present study aimed to study the effect of Hemidesmus indicus plant leaf extract on the liver enzymes in alloxan induced diabetic Wister rats. Hemedesmus indicus plant was successively extracted with different o...
