Abstract
CONTEXT Leonurus artemisia (Lour.) S.Y.Hu (Lamiaceae) (YiMuCao in Chinese) is a traditional Chinese medicine. Leonurus artemisia has been shown to have many pharmacological effects such as increasing uterine contraction amplitude, and tension, but the active components are still unknown. OBJECTIVE The objective of this study is to determine active components of L. Artemisia that are responsible for the biological activity using HPLC and cell membrane-based system. MATERIALS AND METHODS The whole L. artemisia ethanol extract and its eight fractions were screened using Sprague-Dawley rat uterus cell membrane chromatography (CMC) combined with the HPLC/MS system. Oxytocin was used to investigate the activity of CMC column. The effect of active components screened from L. artemisia was studied by tension measurement of isolated rat uterine strips in vitro at a dose of 10(-7)-10(-4 )mol/L with oxytocin as a control. RESULTS The acetone extract showed obvious activity when compared with the eight extracts of L. artemisia. From the acetone extract, in the negative ionization mode, the active compound was identified as genkwanin, with a molecular weight of 283. In vitro pharmacological experiments proved that genkwanin promoted uterine contractions at a dose from 10(-7) to 10(-4 )mol/L. The EC50 value was 4.86 ± 4.21 μmol/L for genkwanin and 4.30 ± 3.65 μmol/L for oxytocin on the contractile amplitude of uterine strips isolated from rats. DISCUSSION AND CONCLUSION Genkwanin was identified as the active compound in L. artemisia by this method. In vitro pharmacological experiments proved that genkwanin promoted uterine contractions. Genkwanin may be used to uterine inertia and may have an effect on postpartum hemorrhage.

Abstract
Recently, some promising advances have been achieved in understanding the chemistry, pharmacology, and action mechanisms of constituents from genus Caulophyllum. Despite this, there is to date no systematic review of those of genus Caulophyllum. This review covers naturally occurring alkaloids and saponins and those resulting from synthetic novel taspine derivatives. The paper further discussed several aspects of this genus, including pharmacological properties, mechanisms of action, pharmacokinetics, and cell membrane chromatography for activity screening. The aim of this paper is to provide a point of reference for pharmaceutical researchers to develop new drugs from constituents of Caulophyllum plants.

Abstract
Novel lipid raft stationary phase chromatography (LRSC), with lipid rafts that contain abundant tropomyosin-related tyrosine kinase A receptors immobilized on the stationary phase, was developed for a high-throughput screening of potentially active antitumor agents. Lestaurtinib was used as a model compound to determine the operational parameters of the LRSC. Of all the factors considered, the particle size of column packing, the column temperature and the flow rate were of immense importance in determining the performance of the established LRSC system. In order to profoundly comprehend the binding interaction between the model drug and the receptors on the column, thermodynamic studies were employed. The results revealed that the interaction was spontaneous and exothermic, a typical enthalpy-driven process. Additionally, the primary forces were hydrogen bonding and van der Waals forces. In evaluating the applicability of the method, active extracts from Albizziae Cortex were screened out using the LRSC system under the optimized conditions. The bioactive components were successfully confirmed by the MTT assay. In conclusion, it could be said that the LRSC is a good model for screening potential antitumor agents because of its viability, rapid response and scalable features.

Abstract
We have developed an online analytical method that combines human periodontal ligament cell membrane chromatography (hPDLC/CMC) with high-performance liquid chromatography and mass spectrometry (LC/MS) for recognizing and identifying osteoplastic active components from Coptidis Rhizoma. Retention fractions on hPDLC/CMC were enriched onto an enrichment column and the components were directly analyzed by combining a 10-port column switcher with an LC/MS system for separation and preliminary identification. Using simvastatin (SIM) as a positive control, berberine from Coptidis Rhizoma was identified as the active component which could act on the hPDLC. The MTT colorimetric assay, alkaline phosphatase (ALP) activity, and staining tests revealed that berberine could promote hPDLC growth, increase the secretion of ALP in the culture medium, and enhance the formation of mineralized nodule, thus it is a potential osteoplastic ingredient. This hPDLC/CMC-online-LC/MS method can be applied for screening active components acting on hPDLC from traditional Chinese medicines exemplified by Coptidis Rhizoma and will be of great utility in drug discovery using natural medicinal herbs as a source of leading compounds.

Abstract
A G-protein-coupled receptor-cell-membrane stationary phase (CMSP) has been prepared by immobilizing cell membranes on the surface of silica, as carrier. The resulting HEK293 alpha1A adrenoceptor cell-membrane stationary phase can be used for rapid on-line chromatographic determination of potential subtype-selective alpha1-adrenoceptor ligand-binding affinities for alpha 1-adrenoceptor subtypes. The objective of the research was to study whether cell lines stably overexpressing subtype receptors could improve the sensitivity and specificity of cell-membrane chromatography (CMC) compared with use of homogenized tissue and cells in primary culture. Effects of mobile-phase ionic strength, sample concentration, and the presence of competitive agents on ligand-receptor interaction in CMSP were also evaluated. We found that cell lines stably overexpressing subtype receptors led to improved sensitivity and specificity in CMC. The technique leads to useful procedures-cell-membrane stationary phases may, for example, facilitate exploration of ligand-receptor interaction and determination of ligand-receptor binding affinity in initial screening and separation of lead compounds or active components in Chinese traditional natural medicine and herbs. This might eventually be an important contribution and an addition to our collection of techniques.
