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

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.

Functional foods provide health benefit beyond basic nutrition. Functional foods fortified with plant ingredients are well known. Ayurveda (Indian System of Medicine) has found several ways in which the medicinal benefits of herbs can be conveyed via certain foods as carriers. Milk is one such carrier which has been effectively used to deliver phytochemicals for targeted health benefits. Indian Kudzu orPueraria tuberosaLinn. (Fabaceae) is an important medicinal plant of Ayurveda, and experiments suggest that it enhances the health benefits of milk when taken with milk as a carrier. Different m

A high-speed countercurrent chromatography and preparative liquid chromatography method was successfully applied to the separation and puriﬁcation of ferulic acid, senkyunolide I and senkyunolide H from the volatile oil of the traditional Chinese medicinal plant Rhizoma Chuanxiong. For the first time, using a two-phase solvent system composed of N-butanol–acetic acid–water (4:1:5, v/v) and a flow rate of 2 mL·min-1, a mixture of SEI and SEH was rapidly obtained by high-speed countercurrent chromatography (HSCCC). The mixture was separated by pre-HPLC with a methanol–water (50:50) mobile phase

Plants are essential for human life. They help people breathe, provide food, clothing, medicine, and fuel, and also safeguard the environment. Plants can be loaded with medicinal properties and possess active substances that can be used for medical purposes. Several beneficial plant species are disappearing as a result of such factors as global warming, increasing population, professional secrecy, insufficient government support for research efforts, and the lack of public understanding of medicinal plants. It takes time to identify medicinal plants, therefore use professionals to assist you.

A HPLC-UV method was developed and validated for determination of stemokerrine and oxystemokerrine in Stemona kerrii roots. The chromatographic separation was performed on a Hypersil BDS C18-column eluted with methanol: 50 mM ammonium acetate solution using a gradient system with a flow rate of 1 mL/min and detection at 300 nm. Stemokerrine and oxystemokerrine showed a linear relationship within the range of 0.5-100 μg/mL. The method was shown to be precise with a RSD <2%. The average percent recovery of stemokerrine was 101.6% and for oxystemokerrine 99.5%. Two samples of S. kerrii were an

Medicinal cannabis is used to relieve the symptoms of certain medical conditions, such as epilepsy. Cannabis is a controlled substance and until recently was illegal in many jurisdictions. Consequently, the study of this plant has been restricted. Proteomics studies on Cannabis sativa reported so far have been primarily based on plant organs and tissues other than buds, such as roots, hypocotyl, leaves, hempseeds and flour. As far as we know, no optimisation of protein extraction from cannabis reproductive tissues has been attempted. Therefore, we set out to assess different protein extraction

Abstract Aloe vera is a medicinal plant used worldwide to treat a variety of conditions and, as such, has important commercial value. Aloin is a principal component of aloe vera leaves and is used for quality control of products containing it. A semiquantitative thin-layer chromatographic (TLC) method for determining the concentration of aloin in aloe-based products was validated. The results were similar to those of a validated high-performance liquid chromatographic method; therefore, TLC, which is a simple, sensitive, specific, rapid, and cheap method, may be ideal for use in any laboratory
