ABSTRACTHerbal formulations are complex natural mixtures. Researchers usually tend to focus more on analysis of nonvolatile components but pay less attention to volatile compounds. In this study, an analytical strategy combining two approaches was established for comprehensive analysis of herbal formulations. Guizhi Fuling capsule (GFC), a drug approved by the FDA to enter phase II clinical trial for treatment of primary dysmenorrhea, was taken as a case for analysis. Gas chromatography–mass spectrometry (GC‐MS) with automated mass spectral deconvolution and identification system (AMDIS) led to rapid identification of 48 volatile components including four acetophenones, three fatty acid esters, 13 phenylpropanoids and 19 sesquiterpenes. Most of them were found from Guizhi. The volatile oils of Guizhi have been proved to exhibit many pharmacological activities. This is helpful in understanding the pharmacological mechanism of GFC. Furthermore, AMDIS turned out to be efficient and reliable for analysis of complex herbal formulations. Rapid‐resolution liquid chromatography (RRLC) coupled with electrospray ionization quadrupole time‐of‐flight tandem mass spectrometry (ESI‐Q‐TOF MS/MS) allowed the identification of 70 nonvolatile components including six acetophenones, 12 galloyl glucoses, 31 monoterpene glycosides, three phenols and 12 triterpene acids. Fragmentation behaviors of assigned components, especially triterpene acids, which are hard to identify by low‐resolution MS, were first investigated by TOF MS/MS. Characteristic ions and typical loss of assigned triterpene acids were summarized. Combinatorial use of GC‐MS‐AMDIS and RRLC‐ESI‐Q‐TOF MS/MS could be of great help in global qualitative analysis of GFC, as well as other herbal products. Copyright © 2012 John Wiley & Sons, Ltd.

AbstractWe report the synthesis of the first organo‐POM with thermoresponsive properties. Our concept will provide chemists with a new tool to design POMs whose solubility is reversibly controllable through an external stimulus. POM–polymer TBA7[POM]‐poly(N,N‐diethylacrylamide) (POM–PDEAAm), was prepared by grafting PDEAAm‐NH2 (obtained by RAFT polymerization) onto the activated Dawson acyl‐POM, α2‐[P2W17O61SnCH2CH2C(O)]6−. Extensive MS analysis was used to monitor the chain‐functionalization steps and to confirm the formation of the hybrid. Aqueous solutions of the (NH4)7[POM–PDEAAm] exhibited a LCST of 38 °C. Thus, the solubility/aggregation of the hybrid was reversibly controlled by changing the temperature. Above 38 °C, the solution became cloudy, and cleared again upon cooling. Dynamic light scattering (DLS) revealed the formation of small aggregates in the range 100 nm. We assumed that the charged POM head units prevented the formation of the larger‐scattering aggregates that are usually observed for PDEAAm, and promoted the formation of micelle‐like structures. The conjugate exhibited a temperature transition, which was different from that of the polymer and depended on the counterions associated with the POM. This result demonstrates the potential for merging organic (in this case, polymer) and inorganic structures to afford materials that exhibit new properties.
Cyclization of Aromatic Propargyl Alcohol with a Thiophene Group Yielding Naphthothiophene Aldehyde Induced by a Ruthenium Complex

AbstractThe reactions of [Cp(PPh3)2RuCl] (Cp=cyclopentadienyl) with phenyl propargylic alcohol 1 a, with a 3‐thiophene group, are explored. The carbene complex 2 a, obtained exclusively from this reaction at low temperature, contains the naphthothiophene group, which is formed through a new cyclization process between the thiophene group and the inner carbon of the triple bond. Details of this process have been revealed by conducting the reaction at room temperature, affording the allenylidene complex 3 a as a side product. Complex 3 a is not converted into 2 a, indicating that the cyclization takes place while the triple bond is π coordinated to the metal center. Complex 2 a reacts with oxygen in the presence of NEt3 at room temperature to afford, in high yield, naphthothiophene aldehyde 4 a, ONEt3, OPPh3, and [Cp(PPh3)2RuCl]. Molecular O2 is likely activated by coordination to the metal center when one of the phosphane ligands dissociates. Then, NEt3 promotes the oxygenation process by reacting with the coordinated O2 to afford ONEt3 and possibly an unobserved oxo‐carbene complex. Coupling of the oxo and carbene ligands then yields 4 a and [Cp(PPh3)2RuCl] in CHCl3. In a solvent system containing MeOH, the oxygenation reaction affords a mixture of 4 a and naphthothiophene ester 5 a–1. The reactions of [Cp(dppf)RuCl] (dppf=1,1′‐bis(diphenylphosphino)ferrocene) with 1 a, also afford the carbene complex 2 a′, 4 a, and 5 a, which have been characterized by X‐ray diffraction analyses. For the phenyl propargylic alcohol 1 b, with a 2‐thiophene substituent, different naphthothiophene aldehyde and ester compounds are also obtained in high yields through a similar cyclization process followed by oxygenation under mild conditions.
