Context Quantitative standardization of plant-based products is challenging albeit essential to maintain their quality. Aims This study aims to develop and validate high-performance thin-layer chromatography (HPTLC) method for the simultaneous determination of rutin (Ru), quercetin (Qu), and gallic acid (Ga) from Psidium guajava Linn. (PG) and Aegle marmelos (L.) Correa. (AM) and correlate wi...

Abstract Bamboo tableware became popular as ecofriendly material. However, industrial products made of bamboo-melamine–formaldehyde resin material are not biodegradable. In addition, harmful compounds were detected if such consumer articles used with hot drinks or food, and risk assessment found that maximum daily dosages melamine formaldehyde exceeded. High-performance thin-layer chromatograph...

in the developing countries of tropical regions, mycotic infections are common cause of skin diseases.the use of medicinal plants in the treatment of skin diseases including mycotic infections is an age-old practice in many parts of the world. the drugs used against dermatophytosis have several side effects, but limited efficacy. there is therefore a distinct need for discovery of new, safer an...

FeiYangchangweiyan capsule (FY capsule), a traditional Chinese medicinal preparation consisting of three medicinal herbs, has been used to treat bacterial dysentery, acute, and chronic gastroenteritis for several decades. In this study, a novel, convenient, accurate, and valid method was developed by using high-performance liquid chromatography (HPLC) coupled with diode array detection...

Conventional algorithms for fingerprint recognition are mainly based on minutiae information. However, the small number of minutiae in partial fingerprints is still a challenge in fingerprint matching. In fingerprint recognition systems, there are frequently appeared partial fingerprints, such as incompletely touching in fingerprint scanning or latent fingerprints. In this paper, we studied the...

We have devised a high performance thin-layer chromatography (HPTLC) densitometry method to resolve the major lipid classes of brain tissue. We used DEAE-Sephadex column chromatography to separate the total lipid into neutral and acidic lipid fractions. The lipid fractions were then spotted on separate HPTLC plates and chromatographed in one dimension using two solvent systems. Quantitation was...

A reversed phase liquid chromatography (RP-HPLC) and thin layer chromatography (HPTLC) densitometry methods as a stability indicating assays of olmesartan medoxomil in presence of its acid or alkaline induced degradation products were developed. Olmesartan medoxomil and its degradation products were analyzed by HPLC equipped with UV-Variable wave length detector at 257 nm where quantitation was...

Background: Urtica dioica L. is a common Himalayan species which produces allergenic substances causing oedema and inflammation in humans. It has become a source of folk medicine for the treatment of many diseases. The leaves and roots both are used internally as a blood purifier and diuretic and an infusion of the plant is used for nasal and menstrual haemorrhage, diabetes, rheumatism, eczema,...

A simple, accurate and rapid high performance thin layer chromatography (HPTLC)- densitometric method was developed for separation and determination of cetirizine (CET) as a long acting antihistamine and montelukast (MON) as an antileukotriene in pharmaceutical dosage forms. The compounds were separated on silica gel 60 F254 HPTLC plates using a mixture of ethyl acetate : methanol : ammonia sol...

A simple, rapid and reliable HPTLC method has been developed for simultaneous estimation of Chebulagic acid and Chebulinic acid in marketed polyherbal formulations. Identification and quantification were performed on 10cm x 10cm, layer thickness 0.2mm, aluminumbacked silica gel 60 F254 HPTLC plates previously washed with methanol. The solvent system consisting of Ethyl Acetate: Toluene: Formic ...
