The Effect of Herbal Medicinal Products on Psoriasis-Like Keratinocytes.

Psoriasis is a chronic inflammatory skin disease characterized by hyperproliferation of keratinocytes and expression of pro-inflammatory cytokines in the epidermis. New biological drugs were developed for the systemic treatment of moderate to severe psoriasis. However, products for the topical treatment of mild psoriasis are still required.

In-vitro evaluation of antimicrobial and insect repellent potential of supercritical-carbon dioxide (SCF-CO) extracts of selected botanicals against stored product pests and foodborne pathogens.

In the present study, the antimicrobial and the insect repellent activity of 16 botanical extracts obtained by supercritical CO (SCF) extraction were evaluated. The present investigation was conducted as there is a necessity for exploration of natural botanical extracts that target both stored product insects and microbes. The antimicrobial activity was studied by disc diffusion and broth microdilution methods against ten microbial species, including Gram-positive bacteria ( and ), Gram-negative bacteria ( and ), and fungi ( and ).

Anti-Inflammatory Effect of a Novel Topical Herbal Composition (VEL-091604) Consisting of Gentian Root, Licorice Root and Willow Bark Extract.

The anti-inflammatory properties of the topical herbal composition VEL-091604 with gentian root, licorice root, and willow bark extract were assessed in a randomized, prospective, placebo-controlled, double-blind ultraviolet (UV)-erythema test study with 42 healthy volunteers in comparison to 1% hydrocortisone acetate. The efficacy and tolerability of VEL-091604 cream 2 times daily over 2 wk was evaluated in an open-label, prospective proof of concept study in 10 subjects with atopic dermatitis using a lesional SCORAD severity score. In the UV-erythema test VEL-091604 cream significantly reduced inflammation compared to placebo and was as effective as 1% hydrocortisone acetate.

The Herbal Bitter Drug Gentiana lutea Modulates Lipid Synthesis in Human Keratinocytes In Vitro and In Vivo.

is a herbal bitter drug that is used to enhance gastrointestinal motility and secretion. Recently we have shown that amarogentin, a characteristic bitter compound of extract (GE), binds to the bitter taste receptors TAS2R1 and TAS2R38 in human keratinocytes, and stimulates the synthesis of epidermal barrier proteins. Here, we wondered if GE also modulates lipid synthesis in human keratinocytes.

CO Plant Extracts Reduce Cholesterol Oxidation in Fish Patties during Cooking and Storage.

Cholesterol oxidation products (COPs) in foods may pose risks for human health. Suitable antioxidants can reduce the formation of COPs in industrial products. Consumer awareness of food additives has brought a need for more natural alternatives.

In Vivo Antitumor Effect of Supercritical CO Extract of Mango Ginger ( Curcuma amada Roxb) in U-87MG Human Glioblastoma Nude Mice Xenografts.

Glioblastoma multiforme (GBM) is one the most aggressive and lethal human neoplasms with poor prognosis and very limited positive treatment options. The antitumor effect of supercritical CO extract of mango ginger ( Curcuma amada Roxb) (CA) with and without irinotecan (IR) was analyzed in U-87MG human glioblastoma multiforme (GBM) cells in vitro and in nude mice xenografts. CA is highly cytotoxic to GBM cells and is synergistic with IR as indicated by the combination index values of <1 in the CompuSyn analysis.

Anticancer potential and mechanism of action of mango ginger (Curcuma amada Roxb.) supercritical CO₂ extract in human glioblastoma cells.

Mango ginger (Curcuma amada Roxb.) is among the less-investigated species of Curcuma for anticancer properties. We have investigated the anticancer potential and the mechanism of action of a supercritical CO2 extract of mango ginger (CA) in the U-87MG human glioblastoma cell line.

Effects of CO2 plant extracts on triacylglycerol oxidation in Atlantic salmon during cooking and storage.

Increasing concern of consumers on the safety of synthetic food additives has created high interest in natural preservatives in food industry. Plant extracts produced by supercritical CO2 technology from rosemary (R), oregano (O) and an antimicrobial blend (AB) consisting of seven different plants were studied for their effects on lipid oxidation in Atlantic salmon (Salmo salar). Fish pieces were marinated with rapeseed oil containing 0, 1, 2 or 4 g of plant extracts/kg of fish.

Improved neuroprotective effects by combining Bacopa monnieri and Rosmarinus officinalis supercritical CO2 extracts.

Ethnobotanical evidence suggests that herbs such as brahmi (Bacopa monnieri) and rosemary (Rosmarinus officinalis) may possess antioxidant and neuroprotective properties. We compared the antioxidant and neuroprotective effects of supercritical extract of Bacopa monnieri and rosemary antioxidant extract obtained from Rosmarinus officinalis as well as their combination to examine the effects on human glial (U-87 MG) and embryonic mouse hypothalamus cells. Bacopa monnieri extract, rosemary antioxidant extract, and their combination (1:1) are not cytotoxic in both glial and embryonic mouse hypothalamus cell lines up to 200 μg/mL concentration.

Composition and biological activity of different extracts from Schisandra sphenanthera and Schisandra chinensis.

Plants of the Schisandraceae family contain a variety of pharmacologically active lignans like schizandrin, deoxyschizandrin, deangeloylgomisin B, gomisin A, gomisin O, gamma-schizandrin and isogomisin O. Here we have compared the composition of different polar and non-polar extracts of Schisandra sphenanthera and Schisandra chinensis. We also have screened the extracts for antiproliferative and anti-inflammatory effects in different cell-based and cell-free assays.

Distribution of aflatoxins between extract and extraction residue of paprika using supercritical carbon dioxide.

Paprika powder, naturally contaminated with aflatoxins, was extracted by supercritical carbon dioxide at standard conditions (300 bar and 50 degrees C). A lipophilic top phase and an aqueous base phase were obtained. These and the extraction residue were analysed by HPLC for aflatoxins.

Phenolic diterpenes, flavones, and rosmarinic acid distribution during the development of leaves, flowers, stems, and roots of Rosmarinus officinalis. Antioxidant activity.

The distribution of six compounds with three different polyphenol skeletons have been studied in Rosmarinus officinalis: phenolic diterpenes (carnosic acid, carnosol, and 12-O-methylcarnosic acid), caffeoyl derivatives (rosmarinic acid), and flavones (isoscutellarein 7-O-glucoside and genkwanin), each showing a characteristic behavior and distribution during the vegetative cycle. Only in leaves were all six compounds present, and the highest accumulation rate was related with the young stages of development. Rosmarinic acid showed the highest concentrations of all the polyphenols in all organs.
