Green and rapid synthesis of silver nanoparticles using Borago officinalis leaf extract: anticancer and antibacterial activities.
This study highlights the facile, reliable, cost effective, and ecofriendly synthesis of silver nanoparticles (AgNPs) using Borago officinalis leaves extract efficiently. The biosynthesis of AgNPs was verified by UV-Vis spectrum which showed the surface plasmon resonance (SPR) band at 422 nm. Transmission electron microscope (TEM) analysis revealed that the particles were spherical, hexagonal, and irregular in shape and had size ranging from 30 to 80 nm. The energy dispersive X-ray spectroscopy (EDX) and elemental mapping have displayed the purity and maximum distribution of silver in the AgNPs. The crystalline nature ...

Review of Anti-Inflammatory Herbal Medicines.
Authors: Ghasemian M, Owlia S, Owlia MB
Abstract
Medicinal plants and their secondary metabolites are progressively used in the treatment of diseases as a complementary medicine. Inflammation is a pathologic condition that includes a wide range of diseases such as rheumatic and immune-mediated conditions, diabetes, cardiovascular accident, and etcetera. We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies. Curcuma longa, Zingiber officinale, Rosmarinus officinalis, Borago officinalis, evening primrose, and Devil's claw are some of the introd...

Effect of scCO2 sorption capacity on the total amount of borage oil loaded by scCO2 impregnation/deposition into a polyurethane-based wound dressing
Publication date: September 2016 Source:The Journal of Supercritical Fluids, Volume 115 Author(s): C.V. da Silva, V.J. Pereira, P.T.V. Rosa, E.C.M. Cabral-Albuquerque, S.A.B. Vieira de Melo, G.M.N. Costa, A.M.A. Dias, H.C. de Sousa, M.E.M. Braga In this work, experimental equilibrium solubility data of scCO2 in polyurethane (PUR) foam (scCO2 sorption capacity) was measured by a gravimetric method for different isotherms (308, 318 and 328K), scCO2 densities (650, 750 and 850kgm−3) and scCO2 exposure times (0.5, 2, 4, 8 and 16h). Sorption data and CO2 desorption coefficients were estimated from desorp...

Content of micronutrients, mineral and trace elements in some Mediterranean spontaneous edible herbs
Conclusion:
The examined species are a good source of mineral elements and micronutrients, making them particularly adapt to integrate a well-balanced diet. The accumulation of heavy metals showed that contaminants in plants may reflect the environmental state in which they develop. Results showed high concentrations of heavy metals in samples taken in locations characterized by high human activity and in some samples from the local market, of which no one knows the collection area.

Officinalioside, a new lignan glucoside from Borago officinalis L.
Abstract
A new lignan glucoside, officinalioside (1), was isolated from n-BuOH fraction of the aerial parts of Borago officinalis L., together with four known compounds: actinidioionoside (2), roseoside (3), crotalionoside C (4) and kaempferol 3-O-β-D-galactopyranoside (5). The structure of the new compound was established by means of spectroscopic and chemical analyses. Compounds 1 and 2 showed a moderate DPPH radical scavenging activity (IC50: 52.6 ± 1.70 and 41.3 ± 0.25 μM, respectively) comparable with that of the standard trolox (16.6 ± 2.2 μM) without any significant cytotoxicity toward...

Photoimmunological properties of borage in bovine neutrophil in vitro model
Publication date: Available online 19 August 2015 Source:Journal of Photochemistry and Photobiology B: Biology Author(s): Firouzeh Asadollahi, Jalil Mehrzad, Mohammad Javad Chaichi, Alireza Taghavi Razavizadeh Borage (Echium amoenum fisch) is one of the most commonly used medicinal plants, and has long been used as a traditional herbal medicine for many (non)infectious diseases in Iran. Study on photoredox and photoimmunology of borage is little. Natural immunomodulatory plants with minimal adverse/toxic effects could help boost animal health and, ultimately, public health. To determine the effect of borage on ...

Mass Spectrometric Confirmation of γ -Linolenic Acid Ester-Linked Ceramide 1 in the Epidermis of Borage Oil Fed Guinea Pigs
Abstract
Ceramide 1 (Cer1), a Cer species with eicosasphingenine (d20:1) amide-linked to two different ω-hydroxy fatty acids (C30wh:0:C32wh:1), which are, in turn, ester-linked to linoleic acid (LNA; 18:2n-6), plays a critical role in maintaining the structural integrity of the epidermal barrier. Prompted by the recovery of a disrupted epidermal barrier with dietary borage oil [BO: 36.5 % LNA and 23.5 % γ-linolenic acid (GLA; 18:3n-6)], in essential fatty acid (EFA)-deficient guinea pigs, we further investigated the effects of BO on the substitution of ester-linked GLA for LNA in these two epidermal C...

Botanical oils enriched in n-6 and n-3 FADS2 products are equally effective in preventing atherosclerosis and fatty liver [Research Articles]
The objective of this study was to determine whether botanical oils enriched in the FADS2 products 18:3 n-6 versus 18:4 n-3 are equally atheroprotective. LDL receptor KO mice were fed one of four atherogenic diets containing 0.2% cholesterol and 10% calories as palm oil (PO) plus 10% calories as: 1) PO; 2) borage oil (BO; 18:3 n-6 enriched); 3) EO (18:4 n-3 enriched); or 4) FO for 16 weeks. Mice fed BO, EO, and FO versus PO had significantly lower plasma total and VLDL cholesterol concentrations; hepatic neutral lipid content and inflammation, aortic CE content, aortic root intimal area and macrophage content; and peritone...

Plectranthus amboinicus leaves stimulate growth of probiotic L. plantarum: Evidence for ethnobotanical use in diarrhea
Conclusion Indian borage leaves have a prebiotic effect on the probiotic bacteria (L. plantarum) which utilizes the phytoconstituents of the leaves by producing necessary metabolic enzymes. This work provides evidence in the traditional use of the leaves in the alleviation of diarrhea by accelerating microbial gut balance during infection.

Singlet oxygen autoxidation of vegetable oils: Evidences for lack of synergy between β-carotene and tocopherols
Publication date: 1 September 2015 Source:Food Chemistry, Volume 182 Author(s): Bogdan Smyk The synergy between β-carotene and tocopherols – antioxidants protecting oils from oxidation, was analyzed in a model system. The model used stripped borage and evening primrose oils. A chlorophyll extract, β-carotene and one of the tocopherols were added together or separately to the oils. Oil oxidation was initiated by singlet oxygen that was produced by chlorophylls irradiated with the use of a xenon lamp equipped with the cut-off 600nm filter. Experiments were carried out at two mole ratios of tocopherols to β-carotene...
