BACKGROUND & OBJECTIVES Cannabis is one of the most commonly abused drugs worldwide. There is a distinct clinical correlation between cannabis abuse and mental disorders. However, it is essential to establish cannabis intake in the abusers in order to establish causality between cannabis and psychiatric illness. The limitations of current detection methods using commercial cassettes prompted us...

• First time HPTLC- Fusarium avenaceum bioassay using mycelium suspension HPTLC-EDA combined with HPTLC-DART-HRMS and HPTLC-ESI-HRMS Preparative-scale isolation of eight multipotent clerodane diterpenes cholinesterase, glucosidase, amylase microbial inhibitory potential compounds Giant goldenrod ( Solidago gigantea Ait.) root extract was screened for bioactive by high-performance thin-layer chr...

Conventional quantity determination of Chinese herbal medicines by High-Performance ThinLayer Chromatography (HPTLC) must be carried out on a TLC scanner for measuring the marker component on the HPTLC plate. Generally the HPTLC image of the herbal drug always takes the photograph as the permanent visual document. Considering the photo of the HPTLC image preserving all the visual quality-relate...

Availability of rapid and reliable methods for detection of quality in plant raw materials and botanicals is urgently needed. The recent HPTLC instrumentation allows to obtain fingerprints useful to ascertain identity and composition. The results of direct application of HPTLC devices in selected cases, using the fingerprint approach, are here reported, considered and compared with other method...

Introduction: Lepa is a bahirparimarjana chikitsa that helps in bringing samyata sthanika dosha and dhatu. Many lepa are mentioned Ayurveda pharmaceutics for the treatment of mukhadooshika. Among it, one combination Lodhra, Kustumburu, Vacha, Vatapallava, Narikelashuktya. Mukhadooshika type kshudraroga, featuring formation pidaka on face. The symptoms mukhadooshika resembles with acne vulgaris....

The fingerprint profiles of methanol extract and ethyl acetate sub fraction of Azadirachta indica leaves were conducted using preliminary phytochemical screening and high performance thin layer chromatography (HPTLC) analysis. Preliminary phytochemical screening was performed using various biochemical tests. Alkaloid, flavonoid, tannin, saponin and phenol were present in both the extract/subfra...

The aim of the work is to develop a simple, rapid, selective and cost effective HPTLC method for the determination of galangin in Alpinia galanga & Alpinia officinarum. The HPTLC densitometric technique was therefore, selected for the quantitative and qualitative determination of galangin in Alpinia galanga and Alpinia officinarum respectively. There are different analytical methods were used t...

Objective: To establish the fingerprint profile of Wedelia chinensis using thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC) technique. Methods: TLC and HPTLC studies were carried out in two different solvent systems, which showed different Rf value. Results: TLC profiling of the extract confirm about the presence of various phytochemicals. HPTLC finger prin...

Liquid-liquid extraction-thin layer chromatography (LLE-TLC) has been a common and routine combined method for detection of drugs in biological materials. Solid-phase extraction (SPE) is gradually replacing the traditional LLE method. High performance thin layer chromatography (HPTLC) has several advantages over TLC. The present work studied the higher efficiency of a new SPE-HPTLC method over ...
