RID serve as a more appropriate measure than phenol sulfuric acid method for natural water-soluble polysaccharides quantification.

With structural diversity of water-soluble polysaccharides, their precise quantitative analysis by phenol‑sulfuric acid method becomes more difficult and challenging. In this study, the quantification analysis of dextran and glucose in phenol sulfuric acid method was compared in this paper. When the concentration is below 90 μg/mL, the quantification of glucose is close to theoretical value, however, glucose derivatives have significantly different absorption.

Study on the Pharmacognosy of S. Spatuliforius.

Sauropus spatulifolius Beille (S. spatulifolius) is the dried plant of the genus Sauropus, and belongs to the family Euphorbiaceae. To study the pharmacognosy of Sauropus spatulifolius Beille (S.

Application of Fourier transform near-infrared spectroscopy combined with GC in rapid and simultaneous determination of essential components in Amomum villosum.

A method is described using rapid and sensitive Fourier transform near-infrared spectroscopy combined with Gas Chromatograpy internal standard method detection for the simultaneous identification and determination of three bioactive compounds in Amomum villosum samples. Partial least squares regression is selected as the analysis type and multiplicative scatter correction, second derivative, and SNV were adopted for the spectral pretreatment. The correlation coefficients (R) of the calibration models were above 0.

Development of a comprehensive quality control method for the quantitative analysis of volatiles and lignans in Magnolia biondii Pamp. by near infrared spectroscopy.

The quality of drug is vital to its curative effect, thus it is important to develop a comprehensive quality control method for commonly used drugs. In this study, we developed a Gas chromatography-mass spectrometry separation method for the qualitative and quantitative analysis of volatiles, together with a High-performance liquid chromatography-mass spectrometry separation method for lignans in Magnolia biondii Pamp..

Pharmacognostical study of Desmodium caudatum.

Desmodium caudatum (Thunb.) DC, is an ever-green plant widely used in the central and southern China with great economic value for their medical values on fever, dysentery, gastroenteritis, rectal prolapse, snake bites, mastitis, and boils carbuncle. Despite its extensive uses as a traditional Chinese medicine, no systematic research on the identification of Desmodium caudatum has been reported.

Prevention of Frey Syndrome With Temporal Fascia Flap in Parotidectomy.

The objective of this study was to evaluate a total parotidectomy performed through a face-lift incision integrated with a temporal fascia flap. We have accomplished a group of 40 cases of total parotidectomy from July 2008 to May 2013. Twenty-two cases accepted a modified performance which combined rhytidectomy incision with temporal fascia flap.

[Quantitative model for patchouli alcohol in Pogostemon cablin by near-infrared spectroscopy].

Objective: To establish a near-infrared spectroscopy quantitative model for rapid determination of the patchouli alcohol content in Pogostemon cablin.

Method: The gas chromatography was adopted for determining the content of patchouli alcohol content in 102 batches of P. cablin samples.

Molecular identification of twelve medicinal plants of Huperziaceae.

Twelve species of Huperziaceae have been identified for resolving the resource depletion of Huperziaceae plants. The chloroplast genes rbcL, rpL16, and psbA-trnH intergenic spacers were used in this study. Identification of different species of Huperziaceae is possible by analyzing the information obtained from rbcL, rpL16, and psbA-trnH intergenic spacer sequences.

[Phylogeny relationship and molecular identification of ten Huperzia species (Huperziaceae) based on matK gene sequences].

Objective: To study the phylogeny relationship and molecular identification of 10 species from Huperzia (Huperziaceae) based on matK gene sequences data.

Method: Total DNA of nine species from Huperzia was extracted; matK gene sequence was amplified by PCR. PCR product was directly sequenced after purification.
