[Objectives] To establish the process flow of preparation of Wufang Babu Poultice and the identification method of thin layer chromatography (TLC). [Methods] For the forming process of Wufang Babu Poultice, the preparation method of mixed pharmaceutical powder with suitable pharmaceutical excipients was adopted. Qualitative identification of medicinal materials in Wufang Babu Poultice (Strychni Semen, Rhei Radix Et Rhizoma, Dipsaci Radix, and Angelicae Sinensis Radix) was carried out by TLC. [Results] Mixed pharmaceutical powder mixed with glycerol, gelatin and other pharmaceutical excipients can be prepared for forming. The test solution chromatography of each medicinal material (Strychni Semen, Rhei Radix et Rhizoma, Dipsaci Radix, Angelicae Sinensis Radix) showed pigment spots of the same color at the same position as its corresponding control medicinal materials and reference chromatography, and the display was clear. [Conclusions] The preparation process is simple and feasible, and can be used as the forming process of Wufang Babu Poultice. The TLC determination method is simple to operate, has good specificity, and has no effect on negative results, and can be used for identification of Wufang Babu Poultice. 展开更多

Plants and plant-based products are the bases of many modern pharmaceuticals that are current in use today for various diseases.The aim of the study was to investigate the biochemical constituents and high performance thin layer chromatography(HPTLC) finger printing of the ethanolic extract of Evolvulus alsinoides.Phytochemical screening was done by standard procedures and HPTLC method was also established to analyze alkaloids,flavonoids and phenolic compounds from the ethanolic extract of Evolvulus alsinoides.Preliminary phytochemical screening showed that ethanol extracted more secondary metabolites than other solvents.HPTLC fingerprinting analysis showed the presence of various alkaloids,flavonoids and phenols(quercetin) in the ethanolic extract.It can be concluded that Evolvulus alsinoides may serve as a source of potent antioxidants that may be used in the prevention of various diseases such as cancer,diabetes and cardiovascular diseases due to the presence of phenolic compounds.HPTLC finger print of Evolvulus alsinoides may be useful in the differentiation of the species from adulterants and act as a biochemical marker for this medicinally important plant in the pharmaceutical industry and plant systematic studies. 展开更多

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 tra- ditional 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 that of a routine LLE-TLC method, in extraction and detection of urinary morphine. Fifty-eight urine samples, primarily identified as mor- phine-positive samples by a strip test, 'were re-screened by LLE-TLC and SPE-HPTLC. The results of LLE-TLC and SPE-HPTLC were then compared with each other. The results showed that the SPE-HPTLC detected 74% of total samples as morphine-positive samples whereas the LLE-TLC detected 48% of the same samples. We further discussed the effect of codeine abuse on TLC analysis of urinary morphine. Regarding the importance of morphine detection in urine, the present combined SPE-HPTLC method is suggested as a replacement method for detection of urinary morphine by many reference laboratories. 展开更多

Dear Editor: Therapeutically active metabolite contents in a med- icinal plant vary in nature, which may impact on its therapeutic efficacy. Bergenia (Saxifragaceae) is an evergreen perennial herb widely distributed in Central and East Asia with about 30 species reported worldwide. It grows at a range of altitudes from the Khasia hills at 400 feet to the temperate Himalayas from Kashmir to Bhutan at 7,000-10,000 feet. Its distribution over a wide range of altitudinal zones makes it a good candidate for studying variations in its metabolic profiles under different climatic conditions. Bergenin (C-glycoside of 4-O-methyl gallic acid) has been identified as a potent active secondary metabolite in Bergenia and other therapeutically active constituents including, among others, gallic acid (3,4,5 trihydroxybenzoic acid), (+) catechin, and gallicin (Fig. 1). 展开更多

[Objectives] To explore whether the thin layer chromatography( TLC) can be used to guide the preparation of drug containing serum of eucalyptus oil. [Methods]Eucalyptus oil samples with different dilution ratio were detected by TLC. Eucalyptus oil was intragastrically administered to mice,serum samples of different eucalyptus oil doses,different intragastric administration methods and different blood sampling times were collected. The above samples were detected by TLC,and the above results were verified by gas chromatography. [Results] TLC can detect concentration difference of eucalyptus oil samples with different dilution ratio. TLC can provide qualitative and semi-quantitative detection of eucalyptus oil in serum. High,medium and low dose of eucalyptus oil in serum had different effects on the growth of MCF-7 cells in the SD rats( P < 0. 05). [Conclusions] TLC can be used to guide the preparation of drug containing serum of eucalyptus oil. 展开更多

[Objectives] To establish a simple and rapid,specific and reproducible thin layer chromatography( TLC) method,and accordingly establish a thin layer identification method for quality control of Glycyrrhiza uralensis. [Methods] According to the physical and chemical properties,components of Glycyrrhiza uralensis were identified by thin layer chromatography. According to Veterinary Pharmacopoeia of the People's Republic of China 2010( Volume Ⅱ) and related literature report,the thin layer chromatography identification method was studied and improved for Glycyrrhiza uralensis.[Results] When the preparation method for test sample solution was 6g Glycyrrhiza uralensis added with 30 mL saturated n-butanol,ultrasonic processing 20 min,filtered,filtrate dried,added 3 mL methanol and obtained Glycyrrhiza uralensis test sample solution. Then,chloroform-methanol-formic acid-ethyl acetate( 10∶ 3∶ 2∶ 3) as developing solvent,clear spot with high degree of separation and reproducibility could be obtained,and can be used for thin layer chromatography identification of ammonium glycyrrhetate in Glycyrrhiza uralensis.[Conclusions] The modified method omitted the step of ether treatment of samples,and directly adopted saturated n-butanol to extract components. It does not influence the detection of chromatographic spots,and solves the issue of sample gelatinizing sticking and filtration,simplifies the test process,and reduces the harm to human body. 展开更多
