Aim - to develop a series of combined medicinal herbal remedies «Dentos» for dental and otorhinolaryngological practice, in which complex effect on different elements of the infectious inflammatory process is achieved by the combination of several groups of biologically active compounds. Materials and methods. Basic phytocomposition is a medicinal preparation "Dentos", which is composite alcohol-water extract on 70% ethanol from the five types of medicinal plant raw materials: the leaves of Eucalyptus viminalis, the herb of Echinacea purpurea, the flowers of Calendula officinalis, the bark of

Résumé :

Despite the fact that the global market for medicinal plants amounts to hundreds of billions of dollars, there is almost no government control over the quality of such pharmaceuticals in most countries of the world. This is partly attributed to the complex composition of plant materials: traditional analytical methodology is based on the use of standard reference samples for each analyte. In this case, preparations based on medicinal plants may contain tens and hundreds of physiologically active components. Isolation of those compounds in a pure form in practice is carried out using preparativ

Résumé :

Medicinal Zhebeimu refers to the dried bulb of the plant Fritillaria thunbergii, which belongs to the family Liliaceae. Their main production sites are in Zhejiang, Jiangsu, and Anhui Provinces, with alkaloids as the main components. In this study, according to Chinese Pharmacopoeia, different mobile phases were investigated. Because most alkaloids in Fritillaria do not have UV absorption, evaporative light scattering detection (ELSD) was used instead of UV to produce the HPLC-ELSD spectra for five F. thunbergii samples and other samples, e.g. F. chuanxiensis, F. anhuiensis, and F. ussuriensis

Résumé :

The plant Jatropha curcas grows well in different parts of Bangladesh and used in many medicinal purposes locally. The alkaloid atherospermidine and a steroid stigmasterol were isolated from the ethyl acetate extract of the stem bark of J. curcas by a combination of column and preparative thin-layer chromatography over silica gel. The structures of these compounds were determined by spectroscopic analysis (UV, IR, 1H NMR and 13C NMR) and by comparison with published data. This is the first report of isolation of the alkaloid atherospermidine from this plant. DOI: http://dx.doi.org/10.3329/dujp

Résumé :

Rauvolfia serpentina, commonly known as Sarpgandha, is a plant well-known for being utilized for several medicinal purposes. Unrestricted collection from natural stands and overexploitation for medicinal and traditional purposes have rendered it endangered, hence there is necessary requirement for the development of cultivation protocols for mass propagation and sustained utilization of the plant. In the present study, in vitro culture of the apical parts of R. serpentina on MS (Murashige and Skoog) medium enriched with NAA resulted in development of callus, whereas multiple shoot regeneration

Résumé :

Neocarya macrophylla has a wide range of medicinal uses in traditional medicine. The aim of the study was to isolate and characterize compound from the stem bark of the plant. (-)-Epicatechin (a flavan-3-ol) was isolated from the ethylacetate soluble fraction of the methanol stem bark extract of the plant using a combination of silica gel and sephadex LH-20 column chromatography. The structure of the compound as (-)-epicatechin was confirmed on the basis of chemical test, 1D- & 2D-NMR spectroscopy and comparison with existing data in literature.

Résumé :

The benefits of ginseng have been mainly attributed to its triterpenoids, called ginsenosides. Recent genome sequencing of the Panax ginseng has paved the way for in-depth proteomic studies of this medicinal plant. The current study was conducted to deepen the proteomic information on the root proteome of Korean ginseng. Proteomic workflow was optimized by testing two different strategies, characterized by the phenol extraction procedure, the presence or the absence of SDS-PAGE fractionation step, and nano-scale liquid chromatographic tandem mass spectrometry (nLC-MS/MS) analysis.

Résumé :

An efficient and accurate fingerprinting method using reversed-phase rapid-resolution liquid-chromatography coupled with photodiode array detection has been developed and optimized to examine the variance in active compounds among Ziziphora clinopodioides Lam from different locations. Three active components, diosmin, linarin and pulegone, were identified by matching their retention times and UV spectra with the corresponding reference compounds. Our results indicated that chromatographic fingerprints, in combination with principal component analysis (PCA) and hierarchical clustering analysis

Résumé :

The composition of root bark oil from Cleistopholis glauca Pierre ex Engler & Diels growing wild in Ivory Coast was investigated by GC (in combination with retention indices) and 13C NMR spectroscopy after partition of hydrocarbons and oxygenated compounds on silica gel. Thirty-one compounds have been identified. C. glauca produces a sesquiterpene-rich oil, patchoulenone (33.5%), cyperene (9.5%) and germacrene D (6.6%) being the main components. Special attention was paid to the identification and quantification of germacrene C (a heat-sensitive compound) and δ-elemene, which were achieved
