the effect of ajwain Trachyspermum ammi extracted by ultrasound assisted solvent on quality properties of silver carp hypophthalmichthys molitrix surimi stored at 4c
Journal of Food Processing and Preservation, 2016Co-Authors: Reza Farahmandfar, Reza Safari, Fahimeh Ahmadi Vavsari, Tahmineh BakhshandehAbstract:Ultrasound-assisted solvent (UAS) has received considerable attention for the recovery of different compounds from various sources. The aim of this study was to evaluate the UAS of ajwain (Trachyspermum ammi) on the quality of silver carp (Hypophthalmichthys molitrix) surimi. Dried powder of plant seeds were added to ethanol (1: 10 w/v) and extraction was done for 30 min at 45C. The mixture was sonicated at 30 kHz for 15 min at 40C. The extract (0.5% and 0.7% w/w) was mixed with surimi. The control and treated samples were analyzed periodically for microbiological and chemical characterizations during 16 days at 4C. Results showed that 0.7% concentration of ajwain could increase the shelf life of silver carp. The sonication and ethanol extraction (UAS) had similar results on quantity and quality analysis of phenolic compounds by using gas chromatography–mass spectrometry. Therefore, UAS could be used, as a replaced method, for extraction from different plant sources. Practical Application Because of suspicious concerns about health hazards of synthetic antioxidants and fast lipid oxidation of silver carp (Hypophthalmichthys molitrix) surimi, huge demand for natural ones which enhanced the shelf life of this food, increased. In this study, ultrasound-assisted solvent (UAS) and ethanol extracted (UAS) of ajwain (Trachyspermum ammi) introduced as potent antioxidant to introduced as potent antioxidants to improve oxidative stability of marine foods and silver carp (H. molitrix) surimi, which are rich sources of valuable polyunsaturated fatty acids.

in vivo efficacy of Trachyspermum ammi anticalcifying protein in urolithiatic rat model
Journal of Ethnopharmacology, 2009Co-Authors: Tanzeer Kaur, Rakesh K Bijarnia, S K Singla, Chanderdeep TandonAbstract:ETHNOPHARMACOLOGICAL RELEVANCE: Many medicinal plants have been employed during ages to treat urinary stones though the rationale behind their use is not well established. Recently, we have successfully purified an anticalcifying protein from the seeds of Trachyspermum ammi (L.) Sprague ex Turril (Umbelliferae) using oxalate depletion assay and deciphered its inhibitory activity against calcium oxalate crystal growth. AIM: In this report, the antilithiatic activity of Trachyspermum ammi anticalcifying protein (TAP) was studied in urolithiatic rat model. METHODOLOGY: Urolithiasis was induced by exposure of 0.4% ethylene glycol (EG) and 1.0% ammonium chloride (NH(4)Cl) for 9 days. The efficacy of TAP was studied in another group given same dose of EG and NH(4)Cl in addition to 2mg/kg body weight of TAP. Further, we evaluated ability of TAP to inhibit the attachment of calcium oxalate (CaO(x)) crystal in kidney tissue and studied the consequences of CaO(x) adhesion on renal functioning and tissue integrity. RESULTS: The antilithiatic potential of TAP was confirmed by its ability to maintain renal functioning, reduce renal injury and decrease crystal excretion in urine and retention in renal tissues. CONCLUSIONS: Thus, the present investigation suggests the potential of TAP in preventing calcium oxalate deposition and forms the basis for the development of antilithiatic drug interventions against urolithiasis.

Methodology Urolithiasis was induced by exposure of 0.4% ethylene glycol (EG) and 1.0% ammonium chloride (NH4Cl) for 9 days. The efficacy of TAP was studied in another group given same dose of EG and NH4Cl in addition to 2 mg/kg body weight of TAP. Further, we evaluated ability of TAP to inhibit the attachment of calcium oxalate (CaOx) crystal in kidney tissue and studied the consequences of CaOx adhesion on renal functioning and tissue integrity. Results The antilithiatic potential of TAP was confirmed by its ability to maintain renal functioning, reduce renal injury and decrease crystal excretion in urine and retention in renal tissues.

purification and characterization of an anticalcifying protein from the seeds of Trachyspermum ammi l
Protein and Peptide Letters, 2009Co-Authors: Tanzeer Kaur, Rakesh K Bijarnia, S K Singla, Chanderdeep TandonAbstract:Till date various plants extract have been studied to reduce the incidence of urolithiasis but the identification of naturally occurring calcium oxalate (CaOx) inhibitory biomolecules from plants was hampered in past by limitation in identification method. The present study is aimed at examining the efficacy of Trachyspermum ammi on CaOx crystallization in vitro and further by combining conventional biochemical methods with recent advances in mass spectrometry, a novel calcium oxalate (CaOx) crystal growth inhibitor was purified from the seeds of Trachyspermum ammi. An anticalcifying protein from the seeds of Trachyspermum ammi was purified by three step purification scheme; ammonium sulphate fractionation, anion exchange chromatography and molecular sieve chromatography based on its ability to inhibit calcium oxalate crystallization in vitro. An anticalcifying protein having molecular weight 107 kDa and isolectric point 6.2 was isolated. Amino acid analysis of Trachyspermum ammi anticalcifying protein (TAP) showed abundant presence of acidic amino acids (Asp and Glu). Matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry of TAP showed similarities with an unnamed protein product of Vitis vinifera (CAO23876) after matching peptide mass fingerprints in MASCOT search engine. Two EF hand domains were identified in unnamed protein product of Vitis vinifera (CAO23876) by SMART normal module. Due to a significant similarity of TAP with unnamed protein product of Vitis vinifera, presence of two EF hand domains in TAP was anticipated, signifying its calcium binding properties which is a feature of most kidney stone inhibitory proteins.
