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...

 Area were collected from Osmaniye province Turkey in April 2018.
 Material method: chemical constituents groups (by GC/MS FTIR spectroscopy, respectively), DPPH technique) activities agar disc diffusion method) SEO i...

Betel leaf (Piper betel L.) is an important plant being widely consumed worldwide as well used in traditional medicine. The present study aims to evaluate the anti-lipid peroxidation and anti-Candida potentials of different varieties extracts. Three India (Kolkata Variety, Varanasi Mysore Variety) were peroxidation, extracts (ethyl acetate, acetone, methanol). Total Phenolic Content (TPC) Flavo...

Recombinant tumor necrosis factor alpha (rTNF-alpha)-induced release of endogenous fatty acids was examined in WEHI 164 clone 13 fibrosarcoma cells using a highly sensitive HPLC method. The initial rTNF-alpha-induced extracellular release of endogenous fatty acids was dominated by 20:4n;-6, 22:4n;-6, 24:4n;-6, and 18:1n;-9 showing relative rates of 2.9, 0.9, 1.1, and 1.0, respectively. Release ...

The capability of antioxidant compounds to reduce gold(III) to gold nanoparticles has been kinetically studied in the presence of cetyltrimethylammonium bromide using stopped-flow mixing technique and resonance light scattering as detection system. This study has given rise to a simple and rapid method for the determination of several synthetic and natural antioxidants used as additives in food...

Bulk Frying Oil (BFO) derived from semi-purified crude palm oil is widely used in Indonesia. Different from refined-bleached-deodorized palm olein that usually undergo full purification and fractionation, BFO is considered as lower quality because it still contains soft stearin fraction. Long shelf life and the reusability of frying oil could be improved by the addition of synthetic antioxidant...

An HPLC method with ultraviolet-visible spectrophotometry detection has been optimized and validated for the simultaneous determination of phenolic compounds, such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as antioxidants, and octyl methyl cinnamate (OMC) as UVB-filter in several personal care products. The dynamic range was between 1 to 250 mg/L with relative standar...

Identification and determination of butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), nordihydroguaiaretic acid (NDGA), propyl gallate (PG) and tert-butylhydroquinone (TBHQ) by means of LC/MS and GC/MS were examined. These five phenolic antioxidants were detected as their pseudo-molecular ions [M-H]- by LC/MS using a Shim-pack FC-ODS column with drying gas. Moreover, BHA, BHT and ...

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...
