The fruits of Heracleum aquilegifolium Wight (Apiaceae) were collected from Western Ghats of the Indian Peninsula. The essential oils were extracted by hydrodistillation. The chemical composition of the essential oils was analysed by gas chromatography and gas chromatography-mass spectrometry (GC-MS). Beta-Pinene (22.3%), 1,8-cineole (20.3%), and beta-phellandrene (12.4%) were the main componen...

In this study, water extract of nettle (Urtica dioica L.) (WEN) was studied for antioxidant, antimicrobial, antiulcer and analgesic properties. The antioxidant properties of WEN were evaluated using different antioxidant tests, including reducing power, free radical scavenging, superoxide anion radical scavenging, hydrogen peroxide scavenging, and metal chelating activities. WEN had powerful an...

The identification and quantification of the phenolic contents of methanolic extracts of three Salvia L. species namely S. brachyantha (Bordz.) Pobed, S. aethiopis L., and S. microstegia Boiss. and Bal. were evaluated using reverse phase high performance liquid chromatography, UV adsorption, and mass spectrometry (RP-HPLC/MS). In order to determine the antioxidant capacity of these species, cup...

Supplementation of the diets of rats with branched chain amino acids (BCAA: leucine, isoleucine, valine) did not alter their susceptibility to chronic poisoning by tansy ragwort (Senecio jacobaea), which contains hepatotoxic pyrrolizidine alkaloids (PA). Phenobarbital in the diet, which alters liver microsomal enzyme activity, also did not alter susceptibility to PA poisoning. A combination of ...

To examine the possibility of using thiacremonone isolated from high-temperature-high-pressure treated garlic, this study investigated the physiological activities properties. The IC50 values of hydroxyl, superoxide, hydrogen peroxide, and nitric oxide radical scavenging activities of thiacremonone were 92.50, 65.05, 12.60, and 81.53 μg/mL, respectively. On the other hand, the activities of vit...

Nitrite-free and low-nitrite meat-curing systems were developed to eliminate or reduce nitrite in frankfurter-type sausages. Different composite meat-curing mixtures were formulated using cochineal and paprika as natural colorants, sodium hypophosphite (SHP) as antimicrobial agent, butylated hydroxyanisole (BHA) as antioxidant and sodium nitrite. The treatment, which contained 0.015% cochineal,...

Zingiber officinale Rosc, commonly called Ginger, is an underground rhizome widely used as a spice in the food and beverage industries. The prominent bioactive component of ginger [6]-gingerol. present study focuses on influence variety maturity stage [6]-gingerol content. Ten authentic cultivars were collected from ICAR-Indian Institute Spice Research, Calicut, Kerala, India analyzed for oleor...

This study was conducted to evaluate the oxidative stability of virgin coconut oil (VCO) during oven test. VCO with and without antioxidants were subjected to oven test at 63°C over a 40 day-storage. The chemical parameters namely peroxide value (PV) and specific absorptivity of conjugated dienes (CDs) and conjugated trienes (CTs) were used to asses VCO stability. VCO samples treated with the m...

Lipoxygenase possessing dual catalytic activities, i.e. dioxygenase and hydroperoxidase, was purified from the cytosols of term placentas from non-smoking women. Concanavalin A affinity chromatography followed by phenyl-Sepharose CL-4B chromatography resulted in the separation of one hydrophobic and one non-hydrophobic isoenzyme. The concanavalin A-purified enzyme was used in all subsequent exp...

The study aims, to find out an effective preservative to extend the shelf-life of Rasogolla, a highly popular sweetmeat due to its special appeal of taste, as well as to assess the effect of preservative on its biochemical and microbial status. Rasogolla available in local market has too short shelf life (2-3days) since its processing and preservation still lack standardization. In this researc...
