Abstract
Walnut oil was extracted using three different eco-friendly extraction methods, solvent extraction (using ethyl acetate [EA] and ethanol [ET]), aqueous enzymatic extraction (AEE), and ultrasound-assisted enzymatic extraction (UAEE), and their lipid yield, lipid composition, physicochemical analysis, mineral composition, total phenols, antioxidant capacity, and antimicrobial activity were analyzed and compared. The AEE technique offered a greater yield (50.6%) than the other extraction methods and gave comparatively higher linoleic acid (66.12%) content. Palmitic, oleic, linoleic, linolenic, and stearic acids were the principal components that GC/MS detected in all the oil samples. UAEE produced the most polyphenols (0.49 mgGAE/g), followed by AEE (0.46 mgGAE/g), EA (0.45 mgGAE/g), and ET (0.35 mgGAE/g). The DPPH assay results were in the order of UAEE (191 μmolTE/kg) > AEE (186 μmolTE/kg) > EA (153 μmolTE/kg) > ET (130 μmolTE/kg). The FRAP assay findings showed a similar pattern: UAEE (112 molTE/kg) > AEE (102 molTE/kg) > EA (96 molTE/kg) > ET (82 molTE/kg). Results suggested that for a higher extraction yield, AEE is the better technique and UAEE is the recommended method for enhancing walnut oil antioxidant capacity. Additionally, it was found that polyphenols considerably increased the antioxidant capacity of walnut oil and are thought to be health-promoting. The results demonstrated the antibacterial effectiveness of the extracted oil against Bacillus subtilis, Bacillus licheniformis, and Staphylococcus aureus. This study provides information about low-cost and ecofriendly technologies of walnut oil extraction for food, cosmetic, and medical uses.

Abstract
:
Bismuth (III) nitrate pentahydrate (BN) was found to be a mild and efficient catalyst for the electrophilic condensation of 5-nitroindazole with a wide range of aldehydes to obtain Bis (5-nitro indazolyl) methanes 3 (a-h) at ambient
temperature. This was structurally confirmed from FTIR, NMR, and HR-MS technique. Molecular docking studies of all
compounds was carried out using breast cancer-causing human estrogen receptor (ER) from Molegro Virtual Docker software. Hydroxy Bis (nitro indazolyl) methanes (3b) were shown better binding affinities and the score obtained was -150.146
Kcal/mol compared with Tamoxifen drug. The major H-bond interactions were observed with the compound 3f and the
value was -5.679. The antimicrobial activity results revealed that compounds 3b and 3d showed promising activity against
bacteria Escherichia coli, Klebsiella pneumonia, Staphylococcus aureus, and Pseudomonas aeruginosa and maximum inhibition against Aspergillus niger and Aspergillus flavus. Methoxy derivatives of Bis (nitro indazolyl methanes) (3e) have
shown better antioxidant activity and low MIC (6.25 µg/ml) observed for the compounds 3a and 3b. The synthesized compounds have a very promising starting point for the development and improvement of anti-breast cancer drugs.

Abstract
The present study aims to evaluate the antibacterial activity and biological properties of two traditional Saharian plants (Cymbopogon schoenanthus and Ziziphus lotus). The plant extracts were obtained by using a different combination of extraction methods (conventional vs. ultrasound-assisted) and solvents (water vs. ethanol:water (50:50, v/v)). The antioxidant profile, anti-inflammatory activity and impact on bacterial growth (foodborne and probiotic bacteria) of the obtained extracts were assessed. The plant species showed the hierarchically more important role in determining the biological properties of the extracts, followed by extraction solvent and extraction conditions. Conventional Z. lotus hydroethanolic extracts showed the highest total phenolic content (20.4 mg GAE/g), while Z. lotus ethanol extracts from ultrasound-assisted process presented the highest content of carotenoids (0.15 mg/g). In addition, ultrasound-assisted Z. lotus hydroethanolic extracts presented the highest in vitro radical scavenging activity, being 7.93 mmol Trolox/g. Multivariate analysis statistics (PCA) showed that both the extraction methodology and the solvent used strongly affected the bacterial growth. Z. lotus mainly decreased the growth rate of S. aureus and L. innocua. Interestingly, the aqueous extracts of this plant as well as those from C. schoenanthus, obtained by conventional extraction, significantly increased the growth rate and the maximal optical density of L. casei. Aqueous extracts of both Z. lotus and C. schoenanthus slightly influenced the growth of Bifidobacterium. Overall, the extracts of these plants showed selective activities with respect to pathogens and probiotic bacteria and may provide an advantage both in terms of antimicrobial and prebiotic activity.

Abstract
Recently there is a great interest in using high energy techniques (HET) which involve microwave or ultrasound-assisted extraction (MAE and UAE) for isolation of natural bioactive compounds from plant foods. Such bioactive compounds are phenolics which were determined from sunflower (Helianthus annuus L.) kernels and hulls (defatted) utilising two different high energy extraction techniques, ultrasound and microwave assisted solvent extraction. All samples were characterised by ultra-high-performance liquid chromatography-electrospray ionization-mass spectrometry (UHPLC-ESI-MS). The effect of parameters such as the nature of the solvent, volume of solvent, temperature and time is discussed. It is proved that the techniques applied had reduced solvent consumption and shorter extraction times, and extraction yields of the analytes were equal to or to some extent higher than those obtained with conventional techniques. Total Phenolic Composition (TPC) of samples examined was studied by the Folin-Ciocalteu method and results were presented in μg gallic acid equivalents (GAE)/g dry extract. Kernels proved to have the higher amount of TPC while the press residues had shown comparable TPC results. The antioxidant activity of samples was spectrophotometrically determined by 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) assay using Butylated hydroxyl toluene (BHT) as reference compound to compare with samples. Sunflower seeds (kernels) showed again the highest antiradical efficiency (AE) compared to hulls and press-residue extract. Afterwards, ferric reducing ability of plasma (FRAP) and trolox equivalent antioxidant capacity (TEAC) assays were used for measuring the antioxidant capacity of samples. Press residue, a by-product of sunflower oil extraction, contained phenolics as shown by UHPLC-ESI-MS analysis. Hence, later on these compounds can be possibly utilised by food or neutraceutical industries. Phenolic substances characterised in hulls, kernels, and press residue were phenolic acids, mainly chlorogenic, caffeic, cinnamic, 4-hydroxybenzoic and p-coumaric.

Abstract
BACKGROUND Vernonia cinerea (L.) Less is used in folk medicine as a remedy for various diseases. OBJECTIVES The present study reports antioxidant and antimicrobial activities of solvent fractions of Vernonia cinerea. METHODS The antioxidant properties of solvent fractions of V. cinerea were evaluated by determining radicals scavenging activity, total flavonoid and phenolic contents measured with the 2,2-diphenyl-1-picryl hydrazyl (DPPH) test, the aluminum chloride and the Folin-ciocalteau methods, respectively. Antimicrobial activities were tested against human pathogenic microorganisms using agar diffusion method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of each active extract were determined. RESULTS The ethyl acetate fraction having the IC50 value of 6.50 µg/mL demonstrated comparable DPPH radical-scavenging activity with standard antioxidants, gallic acid and quercetin included in the study. All fractions displayed moderate antimicrobial potential against the tested pathogens with the zone of inhibition that ranged from 9.0 to 13.5 mm. The MIC (1.56 mg/mL) and MBC (3.13 mg/mL) indicated highest susceptibility of Candida albicans in all fractions. CONCLUSION The results of this study showed that the solvent fractions of V. cinerea possess antioxidant and antimicrobial activities, hence justifying the folkloric use of the plant for the treatment of various ailments in traditional medicine.

Abstract
In the present investigation, comparison of antimicrobial activities of different spices, Curcuma longa, Zingiber officinale, and Mentha arvensis, and medicinal herbs, such as Withania somnifera, Rauvolfia serpentina, Emblica officinalis, Terminalia arjuna, and Centella asiatica, was evaluated. Different extraction solvents (acetone, methanol, ethanol, and water) were used and extracts were examined against Bacillus cereus, Serratia sp., Rhodotorula mucilaginosa, Aspergillus flavus, and Penicillium citrinum isolated from juices. Extracts from the medicinal herb and spices have significant activity. B. cereus was the most sensitive and R. mucilaginosa was the most resistant among the microorganisms tested. Ethanolic and methanolic extract of C. asiatica displayed maximum diameter of inhibition zone against bacteria and yeast and percentage mycelial inhibition against moulds. This study confirmed the potential of selected extracts of spices as effective natural food preservative in juices.

Abstract
Laetiporus sulphureus is an edible wood-rooting basidiomycete. The nutritional and medicinal properties of this mushroom have long been known by traditional practitioners. The aim of this study was to determine the proximate composition, total phenol antioxidant capacity and antimicrobial activities of different extracts of L. sulphureus. Different extraction methodologies, including high energy techniques, were employed and their effect was examined on the activity of the extracts. Optimum extraction methodologies (classical and ultrasound-assisted) provided one fraction containing neutral and polar lipids and the other fraction containing fungal carotenoids and pigments. Fatty acid analysis indicated a predominant level of polyunsaturated fatty acids followed by saturated and mono-unsaturated fatty acids. Both the aqueous methanolic and water extracts contained higher TPC and showed better antioxidant capacity than the ethanolic extract. Irrespective of the type of extraction applied, L. sulphureus showed good antimicrobial activity against all the tested bacteria and fungi, being in some cases stronger than the used antibiotics and mycotics. Therefore, this edible mushroom could be considered as a positive candidate to be utilised by the food industry, not only for obtaining bioactive compounds to be used as natural antioxidants/antimicrobial agents, but possibly also for its nutritional value and health benefits.

Abstract
Essential oils derived from plants have been recognized for decades to exhibit biological activities, including antioxidant, anticancer, and antimicrobial attributes. Antimicrobial activities of these natural plant materials have been intensively explored in recent years, mainly in response to the overwhelming concern of consumers over the safety of synthetic food additives. Gram-negative organisms are believed to be slightly less sensitive to essential oils than Gram-positive bacteria. Generally, a higher concentration is required to obtain the same efficacy in foods than in synthetic media. The combinations of different types of essential oils or with other food additives have been found to potentially exhibit synergistic if not additive effects. This suggests a cost-efficient and wholesome alternative to both food industry and consumers, at the same time adhering to the hurdle technology in inhibiting proliferation of foodborne pathogens. This review aims to examine the conventional methods commonly used for assessment of antimicrobial activities of essential oils and phytochemicals, the use of these substances as antimicrobials in food products, factors that affect their efficacy, synergism between components or with available food preservatives as well as the challenges and future directions of using essential oils and phytochemicals as natural food preservatives.

The essential oils of thyme, oregano, rosemary, verbena, basil, peppermint, pennyroyal and mint were tested against Gram-positive ( Listeria monocytogenes, Clostridium perfringens, Bacillus cereus, Staphylococcus aureus, Enterococcus faecium, Enterococcus faecalis, and Staphylococcus epidermidis) and Gram-negative strains ( Salmonella enterica, Escherichia coli, and Pseudomonas aeruginosa). For most essential oils examined, S. aureus, was the most susceptible bacteria, while P. aeruginosa showed, in general, least susceptibility. Among the eight essential oils evaluated, thyme, oregano and pennyroyal oils showed the greatest antimicrobial activity, followed by rosemary, peppermint and verbena, while basil and mint showed the weakest antimicrobial activity. Most of the essential oils considered in this study exhibited a significant inhibitory effect. Thyme oil showed a promising inhibitory activity even at low concentration, thus revealing its potential as a natural preservative in food products against several causal agents of foodborne diseases and food spoilage. In general, the results demonstrate that, besides flavoring the food, the use of aromatic herbs in gastronomy can also contribute to a bacteriostatic effect against pathogens.

Abstract
UNLABELLED Ear infection is one of the common diseases occurring throughout the world. Different etiological agents are responsible for ear infections. AIM To assess the antimicrobial potential of Terminalia arjuna leaves and bark extracts against Staphylococcus aureus, Acinetobacter sp., Proteus mirabilis, Escherchia coli, Pseudomonas aeruginosa and Candida albicans, pathogens causing ear infections and their comparison with locally available ear drops. MATERIALS AND METHODS Methanol, ethanol, acetone, aqueous (hot and cold) extracts from the leaves and bark of T. arjuna were tested for their antimicrobial activity. RESULTS Of the three organic solvents evaluated, acetonic leaf extract was found to be best against S. aureus. Organic bark extract showed almost equal inhibition of all tested Gram negative bacteria except P. aeruginosa. However, aqueous extract of T. arjuna bark exhibited good activity against S. aureus. All the extracts were unable to exhibit any antifungal activity. CONCLUSION Organic extract obtained from the T. arjuna bark and leaves may be used to treat the bacterial ear pathogens especially S. aureus, which has shown greater inhibition zones than the herbal drops, however, we still need more detailed studies as in vivo testing and pharmacokinetics properties for their therapeutic utility in treating ear infections.

Abstract
Effectiveness of fermentation using lactic acid bacteria (LAB) for recovering lipids and proteins simultaneously from freshwater fish head (FWH) was evaluated. Three different proteolytic LAB (Pediococcus acidilactici NCIM5368, Enterococcus faecium NCIM5335 and Pediococcus acidilactici FD3) isolated from fish processing wastes were employed in the fermentation process. The fermentation conditions involved 10 % (w/w) glucose, 2 % (w/w) NaCl and 10 % (v/w) LAB cultures at 37 °C. The process resulted in 38.4 % of degree of hydrolysis (in case proteins) and a recovery of 63.6 % of the oil present in the material. The fermentation process did not affect the fatty acid profile of lipids. The hydrolyzed protein rich fermentation liquor exhibited DPPH radical scavenging activity (EC50 - 5.1 mg protein) as well as antagonistic properties towards several bacterial and fungal pathogens. The minimum inhibitory concentrations (MIC) of fermentated liquor (with E. faecium NCIM5335 as starter) were 10 and 12 mg/ml for Listeria monocytogenes and Salmonella itridicus, respectively. A higher MIC (60 and 96 mg/ml for Aspergillus ochraceus and Penicillium chrysogenum, respectively) was observed in case of fungal pathogens. Both the oil and protein hydrolysate rich liquor from fish head can be used as biofunctional ingredients in both human food as well as livestock feed formulations.

Abstract
BACKGROUND Due to their low solubility in water, oil-based bioactive compounds require dispersion in a surface-active agent or appropriate solvents to ensure maximum contact with microorganisms. These combinations, however, may change their physical and/or chemical characteristics and consequently alter the desired functionality. The objective of this study was to determine the impact of selected dispersing agents, ethanol, dimethyl sulfoxide (DMSO), and Tween-80, on cold-pressed terpeneless (CPT) Valencia orange oil to function as a free radical scavenger and an antimicrobial food additive. RESULTS When dissolved in ethanol or DMSO, the orange oil fraction had similar minimum inhibitory concentrations (MIC) for Listeria monocytogenes ATCC 19 115 (0.3% and 0.25% v/v respectively), which were significantly lower (P <or= 0.5) than the MIC for Salmonella typhimurium ATCC 14 028 (1% v/v). Both ethanol and DMSO oil dispersion systems exhibited an intermediate MIC (0.75% v/v) for Lactobacillus plantarum WCFS1. The orange oil (up to 3%) in an aqueous solution of 0.1% Tween-80 yielded no inhibitory activities against any of the test bacteria. However, the 1% natural orange oil dispersed in Tween-80 exhibited 56.86% 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical inhibition versus 18.37% and 16.60% when the same level of orange oil was dissolved in DMSO or ethanol, respectively. At the same orange oil concentration, the oil/Tween-80 suspension yielded 57.92% neutralization of hydroxyl radicals. This represents 71.37% of the mannitol antioxidant activity, which was used as a positive control. CONCLUSIONS These findings suggest that Tween-80 is an appropriate dispersing agent only if the antioxidant functionality is desired. If both antimicrobial and antioxidant properties are needed, the CPT Valencia orange oil should be dispersed in either DMSO or ethanol.

In vitro evaluation of Datura innoxia (thorn-apple) for potential antibacterial activity. Indian J Microbiol 2008; 48:353-7.

Abstract
Various parts of Datura innoxia were examined for potential antibacterial activity by preparing their crude aqueous and organic extracts against Gram-negative bacteria (Escherichia coli and Salmonella typhi) and Gram-positive bacteria (Bacillus cereus, Bacillus subtilis and Staphylococcus aureus). The results of agar well diffusion assay indicated that the pattern of inhibition depends largely upon the plant part, solvent used for extraction and the organism tested. Extracts prepared from leaves were shown to have better efficacy than stem and root extracts. Organic extracts provided potent antibacterial activity as compared to aqueous extracts. Among all the extracts, methanolic extract was found most active against almost all the bacterial species tested. Gram-positive bacteria were found most sensitive as compared to Gram-negative bacteria. Staphylococcus aureus was signifi cantly inhibited by almost all the extracts even at very low MIC followed by other Gram-positives. For Escherichia coli (a Gram-negative bacterium), the end point was not reached for ethyl acetate extract while it was very high for other extracts. The study promises an interesting future for designing a potentially active antibacterial agent from Datura innoxia.
