The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

This study aimed to extract and evaluate some properties and the capability of phenolic components from shallot (Allium ascalonicum L.) peels for usage as fish preservative. It was found that shallot peels extracted twice with 70 % ethanol solvent, within 60 minutes, at 60 oC and the ratio of solid/liquid 1/20 (g/mL) gave highest polyphenol and flavonoid yields. Total polyphenol content and total flavonoid content of the extract were 224.34±5.66 mg GAE/g DW and 255.11±4.35 mg QE/g DW, respectively.

The pomelo peel occupies 50% of the fruit mass in pomelo juice processing. It contains large amounts of phenolic compounds, which may provide benefits to human health. These components should be isolated. In this study, the effects of ethanol concentrations, material-to-solvent ratios (g/mL), temperatures and sonication time on total phenolic content (TPC), naringin content and antioxidant capacity (using DPPH assay) of extract solution was evaluated.

High concentrate (HC) diet-induced oxidative stress causes gut epithelial damages associated with apoptosis. Selenium (Se) being an integral component of glutathione peroxidase (GSH-Px) plays an important role in antioxidant defense system. Therefore, increasing dietary Se level would alleviate HC diet-induced injuries in gut mucosa.

The main component of carotenoids (lyco-red) extracted from tomato peels was lycopene, phytoene, phytofluene, b-carotene, cis-lycopene and lutein. Consequently, the higher stability of carotenoids (lyco-red) extracted from tomato peels was observed in alkaline pH ranging from 7 to 10 and temperature ranging from 40 to 70 C.

In the greenhouse experiment, wheat plants (Triticum aestivum L. cv. Giza 168) were treated with 10 mM of maltose and trehalose as foliar spray using Tween 20 as wetting agent at 15, 30 and 45 days post sowing with two times of irrigation at 10 and 20 days intervals. Two samples were taken after 45 and 120 days from planting.

The aim of the present research was to investigate the chemical composition, antioxidant and anti-tumor effects of Cordia dichotoma fruit pulp extract “CDFP-extract”. Day after intraperitoneal inoculation of Ehrlich ascites carcinoma (EAC) cells in mice, CDFP-extract was administered orally at 500 mg/kg body weight (equal to 0.10 of determined LD50) for ten consecutive days.

This in vitro study was aimed to assess the effects of Thymus vulgaris L. and Origanum vulgare L. essential oils (EOs) on cell viability and enzymatic antioxidative system in yeast Saccharomyces cerevisiae. Yeasts were cultivated with different concentrations of thyme (Thymus vulgaris L.) (0.05 – 1.00 µl/ml) and oregano (Origanum vulgare L.) (0.05 – 0.70 µl/ml) EOs for 24 hours. For the present study, gas chromatography-mass spectrometry (GC-MS) analysis was used to quantify chemical composition of EOs. The main components of thyme essential oil were caryophyllene (7.94%), p-cymene (18.

Laggera tomentosa Sch. Bip. ex Oliv. et Hiern (Asteraceae), an endemic Ethiopian medicinal plant, is traditionally used to treat various ailments. Previously, the chemical constituents of the essential oil (EO) of its leaves and inflorescence were documented. However, no data about the chemical compositions of other parts of the EOs of the plant have been reported to date. Moreover, there are no previous biological activity reports on any parts of the EOs of this plant.

In this study, the total phenolic contents and total antioxidant capacities of some commercial bitter melon products (powder, packaged powder, capsule, paste in olive oil), and of unripe and ripe fruits were determined by spectrophotometric and chromatographic methods. The total antioxidant capacities of unripe and ripe bitter melon samples, determined by using the CUPRAC (cupric reducing antioxidant capacity assay) and ABTS (2,2′-azino-bis(3-ethylbenzthiazolin-6-sulfonic acid))/HRP (horseradish peroxidase) methods, were 42.5 and 36.3 µmol TRE (Trolox equivalent) g–1, and 8.7 and 7.

: This paper includes the result of the first study of the chemical composition, antioxidant, antiinflammatory, and antidiabetic activities of the essential oils of Glebionis coronaria (L.) Cass. ex Spach and Glebionis segetum (L.) Fourr. from Turkey. In the current study, nine and twenty-eight constituents were determined in the essential oils of aerial parts of G. coronaria (GCE) (92.1%) and G. segetum (GSE) (90.0%), respectively. The main components were capillin (65.9%) in GCE, capillene (53.4%) in GSE. The essential oil compositions were evaluated and compared with previous researches.
