ABSTRACT
Introduction: Chamaenerion angustifolium (L.) Scop. has a cup-shaped nectary which locates in hollow receptacle, belonging to receptacle nectary. One layer of eqidermis on which modified stoma lie is covered by a thin cuticular layer. The nectary is differentiated from the srperfical layer cells of receptacle and that no special initial has been found. Goal: The aim of this study was to develop a natural Chamaenerion angustifolium (L.) Scop plant’s standardization requirements. Material and Methods: The root samples of natural Chamaenerion angustifolium (L.) Scop was collected from Umnudelger sum, Khentii aimag in August, 2013. The plant material dried under shade at room temperature. Then passed through 120 mesh size to remove coarse powder and fine powder was used for estimation of biologically active compound content in plant material [1, 3, 7]. Shimazdu UV –VIS Spectrophotometer was employed for all spectroscopic measurements using a pair of matched quartz cells and Shimadzu High Perpormance Liquid Chromatography equipment equipped with SPD - 20 A UV detector, CMB - 20 A system controller, CTO-10 AS vp column oven with injector and LC-6AD pumps. Gallic acid, Folin-Ciocalteau, sodium carbonate, methanol, sulfuric acid, acetic acid and glucose used were of the highest commercially available purity [8. 9, 10]. Results: The present study was carried out to develop a simple, rapid, sensitive, accurate, precise spectrophotometric and HPLC method to determine polysaccharide, polyphenolic and gallic acid by simultaneous estimation of in standardization formulation. Chromatographic analysis was carried out by Luna C18 (2) 100A reversed phase column (150 x 4.6 mm) packed with 5μm diameter particles. The mobile phase was 0.1% acedic acid:Methaol (95:5 v/v). The mobile phase was filtered through a 0.45 μm membrane filter. Then it was degassed ultrasonically prior to use. HPLC identification of standard gallic acid was at 278 nm. Flow rate and injection volume were 0.8 ml /min and 20 µl, respectively. Gallic acid was eluted with retention times of 8.2 min respectively. Amounts of gallic acid were 0.3% in plant. The standard deviation values were satisfactorily low and recovery was closed to 100% indicating the reproducibility, accuracy and precision of proposed method. The natural plant contents of the polysaccharid and polyphenolic was found 2.65% and 4.59%, respectively. Conclusion: The results from this study, we developed natural Chamaenerion angustifolium (L.) Scop. plant’s chemical ingredients for the its standardization. Keywords: Chamaenerion angustifolium (L.) Scop., polysaccharide, polyphenolic and gallic acid.
ABSTRACT
BackgroundMonos Pharm LLC has been started production of Dentamon which is an elixir medicine for gumtissues and a oral cavity inflammation and consumer product has been under appreciated today since1998. Now days, as the technology develops, improved levels of consumer demand for consumptionand they want the product easier to use. In this study, sustainable refers to both the technology andstandardization characteristics of gel medicine for a new Dentamon or Dentos gels were prepared using20% ethanol extract for mixture of Chamaenerion angustifolium L, Stellera chamajasme L and Oxytropispseudoglandulosa which are pharmacological active for gum tissues and a oral cavity inflammation.GoalThe aim of this work was to standardize of Dentamon elixir gel medicine and make technological studyof Dentamon.Materials and MethodsThe present study included plant species which were Chamaenerion angustifolium L, Stellerachamajasme L and Oxytropis pseudoglandulosa. Those three medicinal plants were collected fromdifferent regions of Mongolia and samples their upper part of ground. The plants were used for thepurpose of their phytochemical analysis and technological study of gel formulation. For the contentof flavonoids, total coumarin and tannin in the gel and extract of those plants were determined byspectrophotometric method. The direct measurement of the microbiological climacteric was determinedin extract by according to Mongolian National Pharmacopeia and the viscosity property of gel medicinewas identified using viscometer.ResultsThis study has revealed the presence of photochemical considered as active medicinal chemicalconstituents. Chemical tests of the screening and identification of main active components in the plantsunder study were carried out in the ethanol extract (20, 40, 70%) and aqueous extract using generalextraction method. The tannin content of the upper part in water and three different concentrated ethanolextract was found to be (2.16±0.04%, 1.73±0.04%, 2.58±0.04% and 1.74±0.02%), respectively. Thetannin content of upper part in 40% of ethanol extract of the plants was 7.40±0.21% and coumarin contentwas 3.01+0.09% and the total flavanoids content were 0.70+0.03%. There were not detected Esherichiacoli, Salmonella, Pseudomonas aeruginosa and Staphylococcus aureus in plant extracts. The gelmedicine was prepared from concentrated plant extract using dispersion method and and gel formingmaterial selection using 0.5%, 1%, 1.5% and 2% of carbomer. The results from gel formulation assay,the 0.5% of the gel was turbid liquid state, and 1% of the gel was a colorless, clear liquid state, 1.5% gelwas colorless, created very clear and 2% gel was colorless but it was very dense. The pH condition ofthe 1% of Dentos gel was 7.6 and the viscosity property was 7400000 mPa/sec, the flavonoid contentwas 0.165%, the total coumarin content was 0.69 and Pseudomonas aeruginosa, Staphylococcusaureus, Enterobacteriaceae did not detected. Dentos 1% gel was compared its pharmacological trialwith Hi Ora gel which is produced by Himalaya LLC. On the treatment 14 days, Dentos gel more reduced45.9% of wound area index than Hi Ora gel.ConclusionThe 40% ethanolic extracts of the studied plants contained many bioactive chemical constituentsincluding alkoloids, flavonoids, tannin and coumarin. The 1.5% of carbomer was most effectivefor make a new Dentos gel and also new generated gel was most effective against Pseudomonasaeruginosa, Staphylococcus aureus, Enterobacteriaceae. The new generated gel was standardizedby its appearance, viscosity property and content of coumarin, alkaliod, flavonoids and microbiologicalpurity characteristics.
ABSTRACT
Object To study the chemical constituents of Chamaenerion angustifolium (L ) Scop Methods The compounds were isolated on Diaion HP 20 (Tsk), Toyoperari HW 40 (C), MCI gel CHP 20P (Mitsubishi) column and their structures were identified by physiochemical properties and spectral methods Results Four flavonoids were isolated from the whole plant of C angustifolium and they were identified as quercetin 3 O ? D galactoside (Ⅰ), quercetin 3 O ? L arabinoside (Ⅱ), quercetin 3 O (6′ O galloyl) ? D galactoside (Ⅲ), quercetin (Ⅳ) respectively Conclusion Compounds Ⅰ, Ⅱ, Ⅲ were isolated from this plant for the first time
