Dpph Method

Solidago canadensis L. was introduced to Europe as an ornamental plant from North America in 1645 and began to spread during the XIX-XX centuries. Nowadays the species is considered the most aggressive invasive species. On the other hand, S. canadensis is considered to be a medicinal plant. The raw material known as Herba Solidaginis includes herbs of S. canadensis, S. gigantea, and S. virgaurea. These species are known for their diuretic, anti-inflammatory, antimicrobial, antioxidant, antispasmodic properties. The purpose of our study was to analyze the chemical compounds and some biological properties of S. canadensis, growing in Slovakia, to evaluate its therapeutic potential. The total phenolic content (TPC) of the extracts from aerial parts of S. canadensis was determined by the Folin-Ciocalteu method. The evaluation of total flavonoid content (TFC) was performed by using a spectrophotometric method. The flavonoids content was expressed as rutin equivalents (mg REs) per g DW vegetal product. The phytochemical profile of S. canadensis extracts was assessed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The radical scavenging activity of samples was measured using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Reducing power of extracts was determined by the phosphomolybdenum method. Total phenolic contents (TPC) and total flavonoid contents (TFC) of the extracts varied from 204.19 to 293.43 mg GAE.g-1 DW, and 64.99 – 175.25 g QE.g-1 DW, respectively; the best results were obtained for ethanol extract. Some phenolic compounds were identified by HPLC with significant amounts of rutin (211.20 µg.mL-1), quercetin (122.08 µg.mL-1), quercitrin (102.50 µg.mL-1) and chlorogenic acid (147.00 µg.mL-1). The DPPH values in the inflorescences were higher than in the leaves: the antioxidant activity of leaf extracts was in the range from 5.34 to 17.16 mg TE.g-1, for inflorescences, this parameter ranged from 6.09 to 19.87 mg TE.g-1. The high total phenolic compounds and flavonoids can be used as a valuable source of phytochemicals in herbal remedies. Our study of S. canadensis, growing in Slovakia, shows the promising potential that can be evaluated as an effective antioxidant and antimicrobial agent in herbal medicines.

Cyanthillium cinereum(Less.) H. Rob. (Asteraceae) has been traditionally known for its medicinal properties, all aspects of which are yet to be exploited. This study was aimed at investigating the therapeutic potential of polar (methanolic and aqueous) and nonpolar (hexane and chloroform) crude extracts of the whole plant. Several parameters including free-radical (DPPH•, ABTS•+, H2O2and•OH) scavenging, reducing power, protection of DNA against oxidative damage, cytotoxicity, inhibition of oxidative hemolysis in erythrocytes, total phenolic content and inhibition of lipid peroxidation were examined. All the free-radical generating assay models demonstrated positive scavenging efficiency with differential but considerable magnitudes for the four extracts. However, only the hexane extract showed significant H2O2scavenging effect. Lipid peroxidation was estimated by thiobarbituric acid-malondialdehyde (MDA) reaction, and a high degree of inhibition was shown by all the extracts. Reducing power of the polar extracts was higher than the non-polar ones. All extracts showed a concentration-dependent increase in phenolic contents. Oxidative damage to erythrocytes was hindered by all extracts in diverse degrees. XTT assay showed that all extracts have mild cytotoxic property. The aqueous extract evidently demonstrated protective effect on pBR322 plasmid DNA against oxidative breakdown. These results suggested the potential ofC. cinereumas medicine against free-radical-associated oxidative damage and related degenerative diseases involving metabolic stress, genotoxicity and cytotoxicity.

Background: 1,8 cineole-rich supercritical CO2 extract of small cardamom seeds of Alleppey green variety exhibiting prominent antioxidant property was microencapsulated and utilized in formulating an antioxidant-rich custard. However, the antioxidant potency of the prepared custard was not appreciable. To redress the phytochemical loss during custard preparation, custard using nanoliposomes was formulated. Patents related to 1,8 cineole-rich food products have been revised thoroughly. Objective: The objective of the current study is to examine whether nanoencapsulation-mediated entrapment of antioxidants is more effective in fortifying a dessert, namely custard, vis-à-vis microencapsulated (spray dried)-mediated enhancement of antioxidative potency in the same. Methods: Our previous investigations have established that nanoliposome of 1,8 cineole-rich supercritical CO2 extract of small cardamom seeds effectively redresses type 2 diabetes and hypercholesterolemia. In the current investigation, this pre-characterized nanoliposome which exhibited appreciable in vitro and in vivo antioxidant efficacy has been utilized at varying concentrations for fortification of a custard. The designer custard samples have been characterized for their sensory and physicochemical properties, identification of the cardamom antioxidants therein and determination of the synergistic efficacy value of the identified antioxidants. Results: The custard formulated with 0.3% nanoliposomes exhibited appreciable antioxidant potency in terms of DPPH radical scavenging activity (304.58±1.09 mg/ml) and reducing power (0.020±0.001 mg BHT/g custard), conferred by its total phenolic content (0.049±0.004 mg GAE/g custard). It also had relatively more stable textural attributes vis-à-vis the control sample (formulated with the non-encapsulated native extract). GC-MS analysis of the nanoliposome-fortified custard confirmed retention of the spice antioxidants namely1,8- cineole, α-terpinyl acetate, α-terpineol and linalool and its synergistic efficacy value being greater than unity, attested to a synergistic presence of cardamom antioxidants therein. The newly formulated custard retained more than 4.5 times of 1,8-cineole (5.05 mg/g custard) vis-à-vis the custard sample (1.12 mg/g custard) prepared with a microencapsulated (spray-dried) formulation of the extract. Additionally, absence of heavy metals in the formulated custard confirmed it to be safe for consumption. Conclusion: This is the first study on application of nanoliposomes of spiceuticals in formulation of a dessert, and more emphatically on use of a ‘green’ supercritical CO2 extract of spice antioxidants in fortification of a dessert to achieve antioxidant synergy.

The combination of anticancer drugs in nanoparticles has great potential as a promising strategy to maximize efficacies by eradicating resistant, reduce the dosage of the drug and minimize toxicities on the normal cells. Gemcitabine (GEM), a nucleoside analogue, and atorvastatin (ATV), a cholesterol lowering agent, have shown anticancer effect with some limitations. The objective of this in vitro study was to evaluate the antitumor activity of the combination therapy of GEM and ATVencapsulated in a microemulsion (ME) formulation in the HCT116 colon cancer cells. The cytotoxicity and efficacy of the formulation were assessed by the 3- (4,5dimethylthiazole-2-yl)-2,5-diphyneltetrazolium bromide (MTT) assay. The mechanism of cell death was examined by observing the morphological changes of treated cells under light microscope, identifying apoptosis by using the ApopNexin apoptosis detection kit, and viewing the morphological changes in the chromatin structure stained with 4′,6-diamidino-2-phenylindole (DAPI) under the inverted fluorescence microscope. It has been found that reducing the concentration of GEM loaded on ME (GEM-ME) from 5μM to 1.67μM by combining it with 3.33μM of ATV in a ME formulation (GEM/2ATV-ME) has preserved the strong cytotoxicity of GEM-ME against HCT116 cells. The current study proved that formulating GEM with ATV in ME has improved the therapeutic potential of GEM and ATV as anticancer drugs.
