Abstract
A novel CE method was developed for the separation and determination of three main tropane alkaloids in Flos daturae with a capillary coated by graphene oxide (GO). The GO-coated capillary was characterized by SEM, energy dispersive X-ray spectroscopy, and Raman spectroscopy, and the results indicated that the inner surface of the capillary was partially coated by GO. A phosphate solution (40 mM, pH7.0) containing 20% v/v methanol and 30% v/v acetonitrile was used as the running buffer for the analysis of the atropine, scopolamine, and anisodamine. The linear ranges of atropine, scopolamine, and anisodamine was 0.5-200 μg/mL with satisfactory correlation coefficients (R(2)) > 0.9987, and this novel method provided an efficient separation for three tropane alkaloids as well as a good reproducibility and stability. Finally, the method was successfully applied for the determination of these three tropane alkaloids in plant extracts.

Abstract
The strict application of IUPAC rules for the numbering of tropane alkaloids is not always applied by authors and there is hence a lot of confusion in the literature. In most cases, the notation of 3, 6/7-disubstituted derivatives has been chosen arbitrarily, based on NMR and MS data, without taking into account the absolute configuration of these two carbons. This paper discusses the problem and the relevance of CD and NMR to determine molecular configurations. We report on the use of (1)H-NMR anisochrony (Δδ) induced by the Mosher's chiral auxiliary reagents (R)-(-)- and (S)-(+)-α-methoxy-α-trifluoromethyl-phenylacetyl chlorides (MTPA-Cl), to determine the absolute configuration of (3R,6R)-3α-hydroxy-6β-senecioyloxytropane, a disubstituted tropane alkaloid isolated from the aerial parts of Schizanthus grahamii (Solanaceae). These analytical tools should help future works in correctly assigning the configuration of additional 3, 6/7 disubstituted tropane derivatives.

Abstract
The absolute configuration (AC) of 6beta-hydroxy-3alpha-senecioyloxytropane (1), 3alpha-hydroxy-6beta-tigloyloxytropane (2), 3alpha-hydroxy-6beta-senecioyloxytropane (3), and 3alpha-hydroxy-6beta-angeloyloxytropane (4) was assigned as (1R,3R,5S,6R) using density functional theory (DFT) calculations at the B3LYP/DGDZVP level of theory in combination with experimental vibrational circular dichroism (VCD) measurements and comparison with the spectra of similar tropanes. The AC of 1 followed from a sample isolated from Schizanthus grahamii, while those of the mixture of 2 and 3, isolated from the same source, were determined by comparing the VCD measurement to a weighted calculation of the individual VCD spectra according to a 69:31 ratio of 2:3 determined by (1)H NMR signal integration. In turn, Schizanthus pinnatus provided a 7:3 mixture of 1:4 whose AC was determined using the experimental VCD absorptions in the 1150-950 cm(-1) spectral region which were compared with those observed for 1-3 and with those described for other 3alpha,6beta-tropanediol derivatives.

Simultaneous determination of atropine, anisodamine, and scopolamine in plant extract by nonaqueous capillary electrophoresis coupled with electrochemiluminescence and electrochemistry dual detection.

Abstract
A rapid and simple method was demonstrated for the analysis of atropine, anisodamine, and scopolamine by nonaqueous capillary electrophoresis (NACE) coupled with electrochemiluminescence (ECL) and electrochemistry (EC) dual detection. The mixture of acetonitrile (ACN) and 2-propanol containing 1M acetic acid (HAc), 20mM sodium acetate (NaAc), and 2.5mM tetrabutylammonium perchlorate (TBAP) was used as the electrophoretic buffer. Although a short capillary of 18cm was used, the decoupler was not needed and the separation efficiency was good. The linear ranges of atropine, anisodamine, and scopolamine were 0.5-50, 5-2000, and 50-2000microM, respectively. For six replicate measurements of 100microM scopolamine, 15microM atropine, and 200microM anisodamine, the RSDs of ECL intensity, EC current, and migration time were less than 3.6%, 4.5%, and 0.3%, respectively. In addition, because the organic buffer was used, the working electrode (Pt) was not easily fouled and did not need reactivation. The method was also applied for the determination of these three alkaloids in Flos daturae extract.

Abstract
Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) is an effective technique for analysis of complex samples with offering rapid, efficient separation in combination with accurate mass measurement and tandem mass spectrometry (MS/MS). This paper exploits this technique to identify the alkaloids in corydalis yanhusuo, an important antalgic Traditional Chinese Medicine (TCM). The mass spectral fragmentation behavior of one tertiary alkaloid and two quaternary alkaloids was studied in detail. Low-abundance product ions of tertiary and quaternary alkaloids were investigated and compared between each other. Sixteen alkaloids were screened out by using a systematic screening method developed in our laboratory; structures of eight therein were identified by characteristic UV absorption spectrum and positive ion mode of Q-TOF-MS/MS; and two of them were discovered for the first time in corydalis yanhusuo to our knowledge. This research demonstrates the potential of UPLC-Q-TOF-MS in structural characterization and identification of components in traditional Chinese herbal medicines.

Abstract
Separation techniques with high efficiency and sensitive detection have been widely used for quality control of traditional Chinese medicines (TCMs). High-performance liquid chromatography, gas chromatography, and capillary electrophoresis are commonly used to separate various components in TCMs. Ultraviolet detection, fluorescence detection, evaporative light-scattering detection, mass spectrometry and nuclear magnetic resonance can be applied to separation techniques for qualitative and quantitative analysis of TCMs. The development of quality control for TCMs based on quantitative and qualitative analysis from 2000 to 2007 are reviewed; the fingerprint technique is also discussed due to its broad application in the quality control of TCMs. Prospects for further research based on our primary results are also discussed.

Abstract
The Solanaceae is comprised of some 2500 species of cosmopolitan plants, especially native to the American continent. They have great value as food, like the well-known potato, tomato and eggplants, and medicines, like species of Atropa, Withania and Physalis, but many plants of this family are toxic, and sometimes lethal to mammals, in particular to man. Some of them also produce hallucinations and perceptual changes. The toxic species of this family are characterized by the occurrence of a variety of chemical compounds, some of which are responsible for the toxicity and lethality observed after ingestion, while others are suspected to be toxic. In this review, the following toxic compounds belonging to different members of the Solanaceae family are described: Tropane alkaloids ( Atropa, Datura, Hyoscyamus, Mandragora); pyrrolidine and pyrrolic alkaloids ( Nierembergia, Physalis, Solanum); protoalkaloids ( Nierembergia); glycoalkaloids ( Lycopersicon, Solanum); nicotine ( Nicotiana); cardenolides ( Cestrum, Nierembergia); capsaicinoids ( Capsicum); kaurene-type tetracyclic diterpenes ( Cestrum); steroidal glycosides ( Cestrum, Solanum); 1,25-dihydroxyvitamin D3 and vitamin D3 ( Cestrum, Solanum, Nierembergia); and withasteroids, withanolides ( Withania), and physalins ( Physalis). Other bioactive chemical constituents of members of this family are sugar esters and lectins. Phenylpropanoids are not included in this paper.

Abstract
This review presents different solvents and electrolytes commonly used as BGEs in NACE for the analysis of pharmaceutical compounds. Most NACE applications carried out since 1998 for the analysis of compounds of pharmaceutical interest are presented in four tables: (i) analysis of drugs and related substances, (ii) analysis of chiral substances, (iii) analysis of phytochemical extracts and (iv) analysis of drugs in biological fluids. These selected examples are used to illustrate the interest in NACE versus conventional aqueous CE.

Abstract
Amaryllidaceae are known as ornamental plants, furthermore some species of this family contain galanthamine, an acetylcholinesterase inhibitor approved for the treatment of Alzheimer's disease, and other alkaloids with interesting pharmacological activity. In the present work, the quali- and quantitative analysis of Amaryllidaceae-type alkaloids in the bulbs of Narcissus species is presented using different analytical approaches. Extracts of Narcissus pseudonarcissus cv. Carlton and Narcissus jonquilla Quail, were first examined by GC-MS using a Rtx-5 MS (programmed temperature) and the major alkaloids were identified. Together with galanthamine, high contents of haemanthamine, were found. Galanthamine was reliably quantified by GC-MS, whereas haemanthamine partly decomposed under the GC conditions, thus alternative analytical methods were investigated. Firstly, reversed-phase HPLC-ESI-MS was applied to identify and isolate at semipreparative levels haemanthamine. The compound was fully characterized by MS/MS and (1)H NMR and then used as a reference substance. The quantitation of both galanthamine and haemanthamine was then accomplished by capillary electrophoresis with spectrophotometric detection. A non-aqueous (NACE) approach was selected in order to use a running buffer fully compatible with samples in organic solvent. In particular, a mixture methanol-acetonitrile (75:25, v/v) containing ammonium acetate (90 mM) was used as a background electrolyte. The same analytical sample was subjected to GC-MS and NACE analysis; the different selectivity displayed by these techniques allowed different separation profiles that can be useful in phytochemical characterization of the extracts. The GC-MS and NACE methods were validated and applied to the quantitation of galanthamine (GC-MS and NACE) and haemanthamine (NACE) in bulbs of N. jonquilla.
