Development of high-performance thin-layer chromatography method for herbals identification in extemporaneous oral solution

a high-performance thin-layer chromatography method for quantitative determination of quercetin in herbal products

A preparative high performance liquid chromatography method for separation of lecithin: comparison to thin-layer chromatography.

We have developed a high performance liquid chromatography (HPLC) method to separate lecithin from other phospholipid classes and to obtain lecithin from biologic materials. The separation was performed on a preparative 10-micron Spherisorb column with an optimized solvent system consisting of the following components: acetonitrile, isopropanol, methanol, water, and trifluoroacetic acid. The ad...

Determination of oxycodone hydrochloride in oral solutions by high-performance thin-layer chromatography/densitometry.

A thin-layer chromatography/densitometry method was developed and validated for the determination of oxycodone hydrochloride in oral solutions by using silica gel plates. A horizontal technique was used for development of the plates. The optimum composition for the mobile phase, which provided a suitable Rf value of 0.6 for oxycodone, was propanol-acetic acid-water-25% ammonia-methanol (20 + 1 ...

Development and validation of High-performance Thin-layer Chromatography Method for Simultaneous Determination of Polyphenolic Compounds in Medicinal Plants

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...

Development of Validated High-performance Thin-layer Chromatography Method for Simultaneous Determination of Quercetin and Kaempferol in Thespesia populnea

INTRODUCTION Thespesia populnea L. (Family: Malvaceae) is a well-known medicinal plant distributed in tropical regions of the world and cultivated in South Gujarat and indicated to be useful in cutaneous affections, psoriasis, ringworm, and eczema. Bark and fruits are indicated in the diseases of skin, urethritis, and gonorrhea. The juice of fruits is employed in treating certain hepatic diseas...
