Chemical communication plays an important role in reproductive and social behaviour of small mammals. The chemical constituents of urine were the main signal resources that can encode sex and social status. The purpose of the present study was to test volatile chemical substances in urine of the kinship and non-kinship Tupaia belangeri, volatile chemicals in urine were performed by the gas chromatography and mass spectrometry (GC-MS), which is speculated that volatile chemicals in urine may had key role in its kin recognition of T. belangeri. The results showed that the components of volatile chemicals in urine were similar between the kinship and non-kinship T. belangeri, which the main components were Alcohols, Alkanes, Esters and Ketones, but the types of each materials were discrepant. “Formic acid, octyl ester” were absence or existence regularly, and “a-Farnesene” and “2,4-Dithiapentane” were found in kinship and non-kinship T. belangeri, which may be signaling substances in the urine. All of the results suggested that volatile chemical substances in urine were different in kinship and non-kinship T. belangeri, indicating that chemical communication based on signals in urine plays an important role in its kin recognition of T. belangeri.

Chemical constituents of essential oils (EOs) obtained from stem and root of Tephrosia purpurea (Linn.) Pers. and Ipomoea carnea Jacq. were investigated by Gas Chromatography-Mass Spectrometry (GC-MS). Total lipid and oil content was high in the stem than the root of T. purpurea and I. carnea. Essential oils extracted from the stem and root of T. purpurea and I. carnea showed 9 and 8 compounds respectively. Hexadecanoic acid was found to be the principal constituent of stem (69.61%) and root (46.97%) of T. purpurea while 70.61and 88.89% for stem and root, respectively in the case of I. carnea. The findings of the present study suggest that T. purpurea and I. carnea EOs can be used as a source of hexadecanoic acid which could be used for industrial purposes. The essential oils of T. purpurea and I. carnea showed strong repellent activity for males (-0.73 and -0.70 for T. purpurea and I. carnea stem EO respectively) than females (-0.63 and -0.59 for T. purpurea and I. carnea stem EO respectively) against banana pseudostem weevil Odoiporus longicollis. The results indicated that the active compounds of essential oils from stems of T. purpurea and I. carnea can be explored as natural repellents for control of Odoiporus longicollis.

Magnoliae Officinalis Cortex (MOC) is a commonly used traditional Chinese herbal medicine, which is always preliminarily processed by “sweating”. To explore the effects of primary processing on chemical constituents in MOC and the potential chemical markers for differentiating the samples processed by “sweating” and “non sweating”, a method is proposed based on ultra fast liquid chromatography-triple quadrupole-time of flight mass spectrometry (UFLC-Triple TOF MS/MS) and gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS) coupled with multivariate statistical analysis. The obtained data were analyzed by principal component analysis and partial least-squares discriminant analysis. The nonvolatile constituents were identified according to MS accurate mass and MS/MS spectrometry fragmentation information, combined with the software of database search and literatures comparison. The volatile constituents were identified according to the NIST05 library and literatures. All of the results demonstrated that the chemical constituents in MOC samples processed by “sweating” and “non sweating” were clearly distinguished. Seventeen nonvolatile differential constituents and five volatile differential constituents were identified and presented in different change laws. This study will provide the basic information for revealing the difference of chemical constituents in MOC processed by “sweating” and “non sweating” and comprehensive evaluation of its quality.

The accumulation of chemical constituents of some medicinal plants, such as Paeonia ostii T. Hong et J. X. Zhang, Houpoëa officinalis (Rehder and E. H. Wilson) N. H. Xia and C. Y. Wu. and Atractylodes lancea (Thunb.) DC, can precipitate on the surface and form frosts after natural or artificial intervention. The characteristics of these three medicinal plants and their frosts were analyzed by light microscope, polarizing microscope, stereomicroscope, and metalloscope. The results of ordinary Raman of P. ostii and H. officinalis showed that the frosts of P. ostii matched paeonol, while that of H. officinalis matched magnolol and honokiol. In P. ostii and its frost, 19 peaks were identified by UPLC-Q/TOF-MS, and the main component was paeonol. Eleven components were identified in H. officinalis and its frosts, and the main components were magnolol and honokiol. A. lancea and its frosts were analyzed by gas chromatography-mass spectrometry (GC-MS), 21 were identified, and its main components were hinesol and β-eudesmol. These three medicinal plants accumulate compounds and precipitate frosts on the surface. The results show that the components of the frosts provide a basis for quality evaluation and research on similar medicinal plants, and reveals the scientific connotation of “taking the medicinal materials’ precipitated frosts as the best” of P. ostii, H. officinalis, and A. lancea, to some extent.

Abstract Dalbergia cochinchinensis can be distinguished from Dalbergia retusa, Dalbergia bariensis, and Dalbergia oliveri quickly using infrared spectrum characteristic peaks as shown in a previous study. To investigate the components corresponding to the infrared characteristic peaks of Dalbergia cochinchinensis, petroleum ether, ethyl acetate, and butyl alcohol were sequentially used to extract the dispersion liquid of D. cochinchinensis. The petroleum ether extracts were further fractionated by column chromatography, using Fourier-transform infrared spectroscopy (FTIR) to track the characteristic components during separation. FTIR spectra of petroleum ether extractives indicated the presence of aromatic ketones and olefin compounds. The gas chromatography–mass spectrometry research showed some main components and gave possible structure. Furthermore, their detailed structures were characterized thorough a nuclear magnetic resonance approach, and then two possible components (3,5-dihydroxy-7-methoxy-2-phenylchroman-4-one and 3,5,7-trihydroxy-2-phenylchroman-4-one) were identified.

The essential oil ofBetula pendulaRoth. buds was obtained using both hydrodistillation and microdistillation techniques and their chemical compositions were analyzed using both gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). Overall, more than 50 compounds were identified representing 80% and 92% for hydrodistillation and microdistillation, respectively. The main components (by hydrodistillation and microdistillation, respectively) found were α-copaene (12% and 10%), germacrene D (11% and 18%) and δ-cadinene (11% and 15%) in the analyzed essential oils. The microdistillation technique proved to be a useful tool and compliant alternative when compared to hydrodistillation.
