Cinnamaldehyde (CA) is natural plant-derived compound that has been highly appreciated for its medicinal properties. However, little information is known about the regulation of plant intrinsic physiology by CA. To address these gaps, physiological, histochemical, and biochemical approaches were applied to investigate CA-facilitated cadmium (Cd) tolerance in the roots of tobacco (

For preventing emulsion adhesive from developing a solid layer on its surface, an emulsion adhesive stirring and water compensating device was designed and applied to a CT cartoner. Driven by an independent motor, the device stirred the adhesive continuously when the machine was stopped temporarily. The automatic water compensating to adhesive was controlled by a PLC control system. The results of application showed that the solid surface layer was effectively reduced, thereby adhesive waste dropped from 4.22 to 1.08 kg/machine per week. Moreover, the consistence of emulsion adhesive were guaranteed, and maintenance work was decreased.

Polyphenols in plant samples have been extensively studied because phenolic compounds are ubiquitous in plants and can be used as antioxidants in promoting human health. A method for rapid determination of three phenolic compounds (chlorogenic acid, scopoletin and rutin) in plant samples using near-infrared diffuse reflectance spectroscopy (NIRDRS) is studied in this work. Partial least squares (PLS) regression was used for building the calibration models, and the effects of spectral preprocessing and variable selection on the models are investigated for optimization of the models. The results show that individual spectral preprocessing and variable selection has no or slight influence on the models, but the combination of the techniques can significantly improve the models. The combination of continuous wavelet transform (CWT) for removing the variant background, multiplicative scatter correction (MSC) for correcting the scattering effect and randomization test (RT) for selecting the informative variables was found to be the best way for building the optimal models. For validation of the models, the polyphenol contents in an independent sample set were predicted. The correlation coefficients between the predicted values and the contents determined by high performance liquid chromatography (HPLC) analysis are as high as 0.964, 0.948 and 0.934 for chlorogenic acid, scopoletin and rutin, respectively. © 2014 Elsevier B.V.

The antioxidant activities of crude extract and its derived soluble fractions from the flower of Sophora viciifolia were evaluated in five different test systems (DPPH, ABTS, FRAP, reducing power and inhibition of lipid peroxidant models) for the first time. The ethylacetate soluble fraction exhibited the highest antioxidant effect. Correlation analysis suggested that the flavonoids might be the major contributors for the high antioxidant activity of this flower. In addition, 11 compounds were isolated from this flower, and the antioxidant capacities of 5 flavonoids were evaluated by DPPH assay. Compound 3 (luteolin) had a significant DPPH radical-scavenging activity, and was also present at the highest concentration (5.56 mg/g dry sample), implying an important role of 3 for the antioxidant activity of this flower. The study suggests that the flower of S. viciifolia can provide valuable functional ingredients and can be used for the prevention of diseases related to various oxidant by-products of human metabolism. © 2010 Elsevier Ltd.

The foreign matter rejecting performance of a tobacco sorting system decreases with the attenuation of illumination, therefore the function of image intensification was incorporated on the basis of optimized Gauss homomorphic filtering algorithm. The image of tobacco leaf under low illumination was converted swiftly from its RGB (Red-Green-Blue) space into an HSV (Hue-Saturation-Value) space in order to separate color from luminance, and the luminance component V was intensified by a real-time spatial homomorphic filter, then stretched by an introduced adaptive coefficient, finally HSV was converted into RGB. The results showed that this method could effectively correct the color, contrast and luminance of an image under low illumination, well balance uneven illumination. The modified system maintains its good rejecting performance, features better maintainability and operational convenience. Comparing with other image intensification algorithms, this method features better self-adaptability and faster processing speed and is more applicable to real-time intensification of color images. ©, 2015, Editorial Office of Tobacco Science and Technology.

Backgrounds existing in the analytical signal always impair the effectiveness of signals and compromise selectivity and sensitivity of analytical methods. In order to perform further qualitative or quantitative analysis, the background should be corrected with a reasonable method. For this purpose, a new automatic method for background correction, which is based on morphological operations and weighted penalized least squares (MPLS), has been developed in this paper. It requires neither prior knowledge about the background nor an iteration procedure or manual selection of a suitable local minimum value. The method has been successfully applied to simulated datasets as well as experimental datasets from different instruments. The results show that the method is quite flexible and could handle different kinds of backgrounds. The proposed MPLS method is implemented and available as an open source package at http://code.google.com/p/mpls. © 2013 The Royal Society of Chemistry.

Ten edible and medicinal fungi were studied for their abilities to produce polysaccharide in submerged culture. Strain specific variation in intracellular and extracellular polysaccharide production was quantified under laboratory conditions. Among the fungi examined, Agrocybe aegirita Mo-Aa was found to produce high amount (3.77 g/L) of total polysaccharide. Furthermore, optimization of production conditions for A. aegirita Mo-Aa polysaccharide was conducted in submerged culture. Production of A. aegirita Mo-Aa polysaccharide was optimal at pH 5.0, an inoculation size of 480 mg/L, culture period of 9 days and mushroom fermentation medium. Under these optimal conditions, the maximum production of A. aegirita Mo-Aa polysaccharide reached 5.46 g/L. The results obtained will be useful for enhanced production of A. aegirita Mo-Aa polysaccharide on a large scale.

The preprocessing of chromatograms is essential to modern chromatography for further qualitative and quantitative analysis, especially when chromatographic instruments are used for herb products analysis involving large number of samples. To accurately compare and analyze the obtained chromatograms, it is necessary to preprocess, especially align retention time shifts. Here moving window fast Fourier transform (FFT) cross-correlation is introduced to perform nonlinear alignment of high-throughput chromatograms. Since elution characteristics of chromatograms will produce local similarity in retention time shifts, moving window procedure seems to be a better substitute of segmentation steps. The retention time shifts can be calculated and accelerated by FFT cross-correlation. The artifacts can be detected and eliminated from the retention time shifts profile since the continuity of moving window procedure. The proposed method is demonstrated in comparison with recursive alignment by FFT on chromatographic datasets from herb products analysis. It is shown that the proposed method can address nonlinear retention time shift problem in chromatograms with the simple moving window procedure, which will not introduce segments size optimization problem. In additional, the parameters are intuitive and easy to adjust, which makes it off-the-shelf toolbox for alignment of chromatograms. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
