BackgroundFulminant hepatic failure (FHF) is clinical syndrome with very poor prognosis and high mortality there is urgent need for the development of safe and non-toxic hepatoprotective agents for the adequate management of hepatitis. Hepatoprotective effect of the Lepidium sativum ethanolic extract (LSEE) was assessed by D-galactosamine-induced/lipopolysaccharide (400 mg/kg and 30 μg/kg) liver damage model in rats.MethodsHepatoprotective activity of LSEE (150 and 300 mg/kg) and silymarin on D-GalN/LPS induced FHF in rat was assessed using several liver function enzyme parameters. Antioxidant properties as antioxidant stress enzymes were assessed in hepatic Liver as well as mRNA expression of cytokines genes such as TNF-α, IL-6, and IL-10 and stress related genes iNOS and HO-1 were determined by RT-PCR. Protein expression of apoptotic genes were evaluated through western blot. MPO and NF-κB DNA-binding activity was analyzed by ELISA. The magnitude of hepatic impairment was investigated through histopathological evaluation.ResultsMarked amelioration of hepatic injuries by attenuation of serum and lipid peroxidation has been observed as comparable with silymarin (25 mg/kg p.o). D-GalN/LPS induced significant decrease in oxidative stress markers protein level, and albumin. LSEE significantly down-regulated the D-GalN/LPS induced pro-inflammatory cytokines TNFα and IL-6 mRNA expression in dose dependent fashion about 0.47 and 0.26 fold and up-regulates the IL-10 by 1.9 and 2.8 fold, respectively. While encourages hepatoprotective activity by down-regulating mRNA expression of iNOS and HO-1. MPO activity and NF-κB DNA-binding effect significantly increased and was mitigated by LSEE in a dose-dependent style as paralleled with silymarin.ConclusionOur data suggests that pretreatment of LSEE down regulates the caspase 3 and up-regulates the BCl2 protein expression. The above findings revealed that Lepidium sativum has significant hepatoprotective activity.Electronic supplementary materialThe online version of this article (doi:10.1186/s12906-016-1483-4) contains supplementary material, which is available to authorized users.

Recent studies from the author's laboratory indicated that camel urine possesses antiplatelet activity and anti-cancer activity which is not present in bovine urine. The objective of this study is to compare the volatile and elemental components of bovine and camel urine using GC-MS and ICP-MS analysis. We are interested to know the component that performs these biological activities. The freeze dried urine was dissolved in dichloromethane and then derivatization process followed by using BSTFA for GC-MS analysis. Thirty different compounds were analyzed by the derivatization process in full scan mode. For ICP-MS analysis twenty eight important elements were analyzed in both bovine and camel urine. The results of GC-MS and ICP-MS analysis showed marked difference in the urinary metabolites. GC-MS evaluation of camel urine finds a lot of products of metabolism like benzene propanoic acid derivatives, fatty acid derivatives, amino acid derivatives, sugars, prostaglandins and canavanine. Several research reports reveal the metabolomics studies on camel urine but none of them completely reported the pharmacology related metabolomics. The present data of GC-MS suggest and support the previous studies and activities related to camel urine.

None of the research reports reveals the metabolomics and elemental studies on camel milk. Recent studies showed that camel milk possesses anticancer and anti-inflammatory activity. Metabolomics and elemental studies were carried out in camel milk which showed us the pathways and composition that are responsible for the key biological role of camel milk. Camel milk was dissolved in methanol and chloroform fraction and then vortexed and centrifuged. Both the fractions were derivatized by N,O-bis-(trimethylsilyl)trifluoroacetamide (BSTFA) and TMCS after nitrogen purging and analyzed by GC-MS. Camel milk was also analyzed by ICP-MS after microwave digestion. We found that higher alkanes and fatty acids are present in the chloroform fraction and amino acids, sugars and fatty acid derivatives are present in aqueous fractions. All the heavy metals like As, Pb, Cd, Co, Cu, and Ni were in the safe limits in terms of maximum daily intake of these elements. Na, K, Mg, and Ca were also present in the safe limits in terms of maximum daily intake of these elements. These results suggested that the camel milk drinking is safe and there is no health hazard. The present data of GC-MS and ICP-MS correlate the activities related to camel milk.

neurodegenerative diseases (Alzheimer's, parkinson's etc.) causes brain cell damage leading to dementia. the major restriction remains in delivering drug to the central nervous system is blood brain barrier (BBB). the aim of this study was to develop a liposomal drug delivery system of Aphanamixis polystachya leaf extract for the treatment of neurodegenerative diseases such as Alzheimer's and parkinson's disease. in this study Gc-MS analysis is used to determine major constituents of Aphanamixis polystachya leaf extract. Liposomal batches of Aphanamixis polystachya leaf extract was prepared using design of experiment (Doe) and characterized using Malvern zetasizer, transmission electron microscopy (teM), and ft-iR. Stability study of blank and leaf extract loaded liposome were performed in gastric media. In-vivo neurobehavioral and anti-inflammatory studies were performed on mice and rat model respectively. Gc-MS data showed that major constituents of Aphanamixis polystachya leaf extract are 2-Pentanone, different acids (Octadec-9-enoic acid, 5-Hydroxypipeloic acid etc.), and Beta-elemene etc. Malvern Zetasizer and teM data showed that liposome batches of Aphanamixis polystachya leaf extract were in the range of 120-180 nm. Interactions between process parameters and material attributes found to have more impact on the average particle size and polydispersity of liposome batches compared to the impact of each parameter in isolation. Stability studies data suggest that blank and leaf extract loaded liposomes were stable at gastric conditions after 4 hours. In-vivo neurobehavioural study data indicated that significant improvement in the memory function, locomotor activity and ambulatory performance of dementia induced mice was observed for the liposomal batches compared to merely A. polystachya leaf extract. One of the most researched areas in medical science is neuropharmacology. About 1.5 billion people worldwide are suffering from central nervous system diseases and nearly half of adults above 70 years old are expected to develop neurodegenerative diseases such as Alzheimer's and Parkinson's 1. Dementia is a degenerative CNS condition that affects intellectual abilities and memory. Alzheimer's, Huntington's, and Parkinson's, which are neurodegenerative diseases, can cause damage to different sets of brain cells leading to dementia 2-4. Therefore, degenerative conditions, brain infections and stroke do alter the blood-brain barrier (BBB) causing foreign molecules to travers BBB and induce inflammation. However, altered BBB could be utilized as a mean for drug delivery into the brain. Currently, most therapies are symptomatic 5 , which make room for improvement in drug delivery system and potential discovery of new molecules. At present many CNS drugs such as tacrine, rivastigmine, donepezil, are cholinesterase inhibitor are used for the treatment of Alzheimer's disease. Their main restriction, however, remains in the proper delivery to target region due to the BBB 6-8 .

In the present study, various phytoconstituents of methanolic extract of Foeniculum vulgare were identified using gas-chromatography mass spectrometry (GC-MS) method. GC-MS method was also applied for the analysis of biomarker fenchone in extract and eight different commercial formulations. The mass of prepared extract and formulations A-D and H (commercial herbal mixtures and commercial extract) used for the analysis of fenchone was 10 g. However, the mass of formulations E-G (soft gelatin capsules) was 100 mg. Fifty seven different phytoconstituents were identified in the methanolic extract of F. vulgare using GC-MS technique. The main compounds identified were trans-anethole (31.49%), 2-pentanone (25.01%), fenchone (11.68%) and benzaldehyde-4-methoxy (8.01%). Several other compounds were also identified in higher amounts and some compounds were identified in trace amounts. Many compounds have been reported for the first time in the methanolic extract of F. vulgare. The amount of fenchone was found to be maximum in plant extract (9.789 mg/g) in comparison with other commercial formulations by the proposed GC-MS technique. In three different commercial formulations (F, G and H), the amount of fenchone was obtained as more than 1.0 mg/g. However, in five different commercial formulations (A, B, C, D and E), the amount of fenchone was recorded as less than 0.1 mg/g. This method could be utilized for the analysis of fenchone contents in the commercial formulations containing fenchone as an active ingredient. The results obtained in this work could be useful in standardization of commercial formulations containing fenchone.
