Abstract
Zhishi-Xiebai-Guizhi Decoction (ZSXBGZD), a traditional Chinese medicine (TCM) formula, has been used for treatment of coronary heart disease and myocardial infarction for nearly two thousand years. However, the chemical composition of ZSXBGZD is still unclear. In order to obtain the chemical profile of ZSXBGZD, an ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) method was utilized for the identification of its multi-constituents. As a result, a total of 148 compounds were identified based on their retention times, accurate masses and MS/MS data. In addition, an optimized UPLC fingerprint analysis, combined with chemometrics such as similarity analysis (SA), hierarchical cluster analysis (HCA), principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) was developed for quality assessment of ZSXBGZD. Multivariate data analysis revealed that samples could be classified correctly according to their geographic origins, and four compounds neohesperidin, naringin, guanosine and adenosine contributed the most to classification. The established UPLC method with multi-wavelength detection was further validated and implemented for simultaneous quantification of 12 representative ingredients in the prescription, including guanosine, adenosine, 2'-deoxyadenoside, syringin, magnoloside A, forsythoside A, naringin, hesperidin, cinnamaldehyde, neohesperidin, honokiol and magnolol. This is the first report on the comprehensive profiling of major chemical components in ZSXBGZD. The results of the study could help to uncover the chemical basis of ZSXBGZD and possess potential value for quality evaluation purpose.

Abstract
While the chemical composition of leaf and stem bark essential oils of the Chinese cinnamon, Cinnamomum cassia (L.) J. Presl, has been well investigated, little is known about the volatilom of its buds, which appeared recently on German markets. Soxhlet extracts of the commercial samples were prepared, fractionated using silica gel and characterised by gas chromatography-flame ionisation detector (GC-FID) for semi-quantification, by gas chromatography-mass spectrometry (GC-MS) for identification and by GC-FID/olfactometry for sensory evaluation. Cinnamaldehyde was the most abundant compound with concentrations up to 40 mg/g sample. In total, 36 compounds were identified and 30 were semi-quantified. The extracts contained mostly phenylpropanoids, mono- and sesquiterpene hydrocarbons and oxygenated derivatives. Because of the high abundance of cinnamaldehyde, the aldehyde fraction was removed from the extracts by adding hydrogen sulphite to improve both the detection of trace compounds and column chromatography. The aldehyde fraction was analysed by GC-MS separately. The highest flavour dilution factor of 316 was calculated for cinnamaldehyde. Other main sensory contributors were 2-phenylethanol and cinnamyl alcohol. This report provides the first GC-olfactometry data of a plant part of a Cinnamomum species. The strongly lignified C. cassia buds combine a high abundance of cinnamaldehyde with comparably low coumarin concentrations (<0.48 mg/g), and provide a large cinnamaldehyde depot for slow release applications.

Abstract
There is significant interest in the development of a sustainable and integrated process for the extraction of essential oils and separation of biopolymers by using novel and efficient solvent systems. Herein, cassia essential oil enriched in coumarin is extracted from Cinnamomum cassia bark by using a protic ionic liquid (IL), ethylammonium nitrate (EAN), through dissolution and the creation of a biphasic system with the help of diethyl ether. The process has been perfected, in terms of higher biomass dissolution ability and essential oil yield through the addition of aprotic ILs (based on the 1-butyl-3-methylimidazolium (C4 mim) cation and chloride or acetate anions) to EAN. After extraction of oil, cellulose-rich material and free lignin were regenerated from biomass-IL solutions by using a 1:1 mixture of acetone-water. The purity of the extracted essential oil and biopolymers were ascertained by means of FTIR spectroscopy, NMR spectroscopy, and GC-MS techniques. Because lignin contains UV-blocking chromophores, the oil-free residual lignocellulosic material has been directly utilized to construct UV-light-resistant composite materials in conjunction with the biopolymer chitosan. Composite material thus obtained was processed to form biodegradable films, which were characterized for mechanical and optical properties. The films showed excellent UV-light resistance and mechanical properties, thereby making it a material suitable for packaging and light-sensitive applications.
