Crataeva tapia Linn. ssp. odora (Jacob.) Almeida, a traditional medicinal plant, which is valued for its benefits in the management of urinary and inflammatory disorders. Leaves are externally rubefacient and used in rheumatism; internally they are given as febrifuge and tonic. The leaves also act as anti-periodic. The current study was therefore carried out to provide requisite pharmacognostic...

The effects of non-ionic surfactants as mobile phase additives on the fluorescence intensity of dansyl derivatives of biogenic amines in high-performance thin-layer chromatography (HPTLC) were investigated. The dansyl derivatives of putrescine, cadaverine, spermidine and spermine were separated by HPTLC with silica gel as stationary phase and an eluent consisting of chloroform–triethylamine (2 ...

Cotinine, as the main metabolite of nicotine, has been determined in urine using solid-phase extraction and the high-performance thin-layer chromatographic (SPE-HPTLC) method. The urine samples were collected from a group of 35 male adolescents which were moderate or significantly exposed to home environmental tobacco smoke (ETS). l-methyl-2-pyrrolidinone was used as the internal standard in th...

The present study investigates a quantitative high performance thin layer chromatographic (HPTLC) method for chlorogenic acid and hyperoside determination from berry extracts. Chlorogenic acid and hyperoside were extracted using a methanol and water mixture and separated on a HPTLC 60F254 silica gel plates with ethyl acetate, acetic acid, formic acid and water 10:1.1:1.1:2.3 (v/v/v/v) as mobile...

A simple, precise and sensitive high performance thin layer chromatographic (HPTLC) method has been developed and validated for drug of choice Lumefantrine in treatment of malaria (P. falciparum). Silica gel 60 F254 HPTLC precoated plates were used for quantitative analytical purpose. Methanol water 9.5 + 0.5 (v/v) was used as the solvent system. Densitometric scanning was carried out with deut...

A sensitive and accurate high-performance thin layer chromatography (HPTLC) method has been developed to determine the quantity of 6-gingerol in the methanolic extract of Zingiber officinale containing dietary supplements, teas and commercial creams. 6-gingerol was separated on aluminumbacked silica gel 60 F254 plates with n-hexane:ethyl acetate 40:60 (%, v/v) as mobile phase. A compact band wa...

HPTLC analysis was carried out to determine the steroid compounds profile in the whole-plant samples of selected Polygonum species (P. chinense, P. glabrum and P. barbatum). The methanol extract of whole-plant samples obtained from Polygonum species (P. chinense, P. glabrum and P. barbatum) showed 6, 6 and 5 compounds, respectively, and were compared with stigmasterol and solasodine standards. ...

A new simple, precise and selective high performance thin layer chromatographic (HPTLC) method has been developed and validated for simultaneous determination of ondansetron hydrochloride and omeprazole in tablets. Identification and determination were performed on 20 cm × 10 cm aluminium-backed TLC plates, coated with 0.2 mm layers of silica gel 60 F254, previously washed with methanol. Ethyl ...

Abstract Background Fumaria parviflora (Lam.), commonly known as “fine-leaved fumitory,” is well for its therapeutic properties in the Indian traditional medicinal system. The presence of important bioactive compounds plants makes them pharmacologically valuable. Therefore, present study, high-performance thin layer chromatography (HPTLC) analysis (whole plant) methanolic extract was performed ...

ABSTRACT. Quisqualis indica (Q. indica; Rangoon creeper) is found in Asia and finds its place Ayurvedic texts, ethno-medicine as well modern research. Its leaves contain important constituents like rutin, quisqualis acid, trigonelline, L-proline L-asparagine. Traditionally, the are used antipyretic, anti-flatulent, anti-inflammatory, anti-septic, anti-diarrhoeal. Modern pharmacological research...
