Saffron is considered as the most expensive spice in world. Due to low production, high demand and cost, saffron very prone adulteration for economic benefits while putting public health at risk. The significant characteristic determining quality of coloring strength (crocin content), which determined by measuring UV-Vis absorption 440 nm aqueous preparations this spice. Picrocrocin safranal ar...

Phenolic acids are aromatic secondary plant metabolites, widely spread throughout the plant kingdom. Existing analytical methods for phenolic acids originated from interest in their biological roles as secondary metabolites and from their roles in food quality and their organoleptic properties. Recent interest in phenolic acids stems from their potential protective role, through ingestion of fr...

The effects of mead wort heat treatment on the mead fermentation process and antioxidant activity were tested. The experiment was conducted with the use of two different honeys (multiflorous and honeydew) collected from the Lower Silesia region (Poland). Heat treatment was performed with the use of a traditional technique (gently boiling), the more commonly used pasteurization, and without heat...

Objectives: As per requisition of current regulatory requirements, simple, rapid and sensitive method by 33 factorial QbD approach was established validated for Levosulpiride Ilaprazole RP-HPLC. Method: A simple RP-HPLC has been developed with different parameters such as linearity, precision, repeatability, LOD, LOQ, accuracy ICH guidelines (Q2R1). Statistical data analysis done obtained from ...

tetracyclines (tcs) are broad-spectrum antibiotics that are used widely in veterinary medicine. the present study was carried out to trace the residues of oxytetracycline (otc) and tetracycline (tc) in pasteurized milk that is marketed in tehran with the use of a high performance liquid chromatography (hplc). ninety milk samples were collected during five sequential days from the products of si...

High Performance Liquid Chromatography (HPLC), Steroidal Saponins, Avena sativa, Etioplasts Reversed phase high performance liquid chromatog­ raphy offers an efficient and rapid method for analysis of steroidal saponins. Crude extracts from primary leaves of Avena sativa and isolated etioplasts therefrom have been resolved into four saponins (avenacosides) using a wateracetonitrile gradient sys...

t-2 toxin is the most poisonous trichothecene produced by fusarium species especially f.sporotrichioides . t-2 toxin is a biological contaminant in a number of agricultural commodities that can cause severe diseases among humans and animals and even lead to death. the aim of the current study is the analysis of t-2 mycotoxin in fusarium species by high-performance liquid chromatography (hplc) c...

This paper focuses on the first investigation of 19th-century manufacture red lake pigments obtained from madder by Winsor & Newton (W&N), prominent artists’ colourman at that time. The approach to their was carried out studying entries company’s book P1, found in W&N 19th Century Archive Database. Eleven production records were discovered under names such as Rose Madder, Madder Car...

The aim of the current study was to determine the profile and content of polyphenols present in Erica cinerea, an important plant species from Northern Portuguese flora and often reported as having anti-inflammatory, antioxidant, and anti-radical activity. The analysis of polyphenols was performed by HPLC-DAD/UV-Vis, and the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+) method...
