Cornus species fruits are well known as a rich source of antioxidant compounds responsible for their diverse health benefits. The present study aims to investigate the variation of the total antioxidant capacity of Cornelian cherry (Cornus mas L.) fruits during storage, using high-performance thin-layer chromatography (HPTLC) and two spectrophotometric assays based on different mechanisms: the ...

Soy (Glycine max L., Fabaceae) and soy products are becoming more popular because of their low toxicity and therapeutic effects. Soy possesses antioxidant, anti-inflammatory and anti-allergic properties, however, the most important is its estrogenic activity associated with occurrence of phytoestrogens. Isoflavones with phytoestrogenic effects were determined in four commercially available soya...

Ayurveda medicines are a time-tested and valuable resource for healing, even today, globally. Hence the quality control standards Ayurvedic formulations is need of time because commercialization. Despite availability modern equipment techniques, not all have been standardized as per day protocol. Dooshivishari agada (DVA), herbo-mineral preparation; mentioned in text Asthangha hrudaya context t...

Present study deals with two Spectrophotometric methods, Conventional Spectrophotometric Estimation and Area under Curve Method and a chromatographic method for estimation of Cefixime by using five different hydrotropic agents. These include Ammonium acetate (6M), Potassium acetate (5M), Potassium citrate (0.5 M), Sodium citrate (1.25 M) and Urea (8M). Area under curve method was based on measu...

A specific, accurate and reproducible stability-indicating high performance thin layer chromatography (HPTLC) method was developed for the estimation of flurbiprofen and chloramphenicol in the presence of their degradation products. Degradation studies of both the drugs were carried out in acidic, alkaline, neutral, oxidative, photolytic and thermal stress conditions. Separation was performed o...

Changes of glycosphingolipids (GSLs) in the bipotential cell differentiation of human promyelocytic leukemia cell line HL-60 cells were investigated by high-performance thinlayer chromatography (HPTLC). with special reference to morphological and functional changes, such as phagocytosis and nitroblue tetrazolium (NBT) reduction. Nine molecular species of neutral GSLs and 1 3 or more species of ...

A simple, precise and accurate high-performance thin-layer chromatographic method has been established for quantitative determination of quinine. Conditions were also optimized for best possible extraction of quinine via varying concentrations of diethyl amine in different solvents (n-hexane, chloroform, ethyl acetate and methanol) for maximum recovery of quinine. Methanol modified with 20 % DE...

Um método foi desenvolvido e validado para a determinação de ocratoxina A (OTA) em vinho. Foi utilizado um sistema contendo um detector de carga acoplada (CCD) para adquirir as imagens fluorescentes da micotoxina obtidas a partir das placas de cromatografia em camada delgada de alta eficiência (HPTLC) sob luz ultravioleta. O método desenvolvido mostrou recuperação média de 90,4%. O limite de qu...

The present study was aimed at identification, isolation and quantification of marker compound Lupeol in Derris heyneana (Wight and Arn) Benth. by using HPTLC. A simple and sensitive High-Performance Thin-Layer Chromatographic (HPTLC) method validation was carried out as per the ICH guidelines for the identification and quantification of biomarker lupeol in root, stem and leaves of Derris heyne...
