Effect of three kinds of Chinese Herbal Medicine on the Viscosity of the Thickeners for Toothpaste

The effects of Scutellaria baicalensis, Panax notoginseng and Ilex rotunda on the viscosities of CMC and Xanthan gum were researched in this paper. Results showed that the viscosities of CMC decrease rapidly with Panax notoginseng;the viscosities of CMC decrease with Scutellaria baicalensis;the viscosities of CMC decrease slowly with Ilex rotunda. The viscosities of Xanthan gum are almost stable with Scutellaria baicalensis, Panax notoginseng and Ilex rotunda respectively;and the viscosities of Xanthan gum increase with the increase of the Scutellaria baicalensis concentration. There is a side chain on the molecular chain of Xanthan gum, which can form a rod-shaped double helix complex to protect the main chain. There is no side chain on the molecular chain of CMC, and the main chain is “bare”. So, compared to xanthan gum, the molecular chain of CMC is is more susceptible to external influences.

Rotunda建筑形制在中国近代大学中的移植与变异

"Rotunda"是一种以圆形大厅及穹顶为典型特征的集中式构图的建筑形制。它早期主要应用于欧洲宗教建筑,后逐渐推广到商业、休闲、政府、文教、居住等世俗建筑中。自19世纪末开始,这种源自欧洲的建筑形制被逐渐移植到了中国近代大学校园之中,并与中国传统建筑文化相结合。本文简述了"Rotunda"的特征及发展,归纳分析了该形制在中国近代大学校园建筑中的代表作品及其主要特点。

Effects of Boesenbergia rotunda （L.） Mansf. on sexual behaviour of male rats

Aim： To study the effects of Boesenbergia rotunda （Krachai） on sexual behaviour in male albino rats. Methods： Thirty-two male Wistar rats were equally divided into four groups： experimental groups were gavaged with the ethanolic extract of the rhizome of B. rotunda at doses of 60, 120 and 240 mg/kg and a control group received distilled water, for 60 days. Sexual behaviour, reproductive organs, diameter of seminiferous tubule, epididymal sperm density, and androgenic hormones were evaluated. Results： Within 30-min observation, there was no significant difference of courtship behaviour, mount frequency （MF）, intromission frequency （IF）, mount latency （ML）, intromission latency （IL）, copulatory efficiency or intercopulatory interval in male rats. In three 10-min intervals over a 30-min period, courtship behaviour and MF during the first 10-min were significantly higher than those in the second and third i0-min observation in all groups, whereas IF had no significant difference. All doses of B. rotunda extract significantly increased the relative testicular weight and the diameter of the seminiferous tubules. The dose of 60 mg/kg also significantly increased the relative weight of the seminal vesicle. Nevertheless, the sperm density, serum testosterone and androstenedione levels were not affected by the B. rotunda extract. Conclusion： B. rotunda does not affect sexual behaviour nor serum androgenic levels.

Extraction and Crystal Structure of Pedunculoside

The title compound of pedunculoside （C36H58O10）, a main active triterpenoid saponin of Ilicis Rotundae Cortex, was isolated from the dried bark of Ilex rotunda Thunb., and characterized by X-ray diffraction analysis. It crystallizes in the orthorhombic system, space group P212121 with C36H58O10, a = 13.046（3）, b = 21.038（4）, c = 28.413（6） A, V = 7798.28（3） A3, Z = 8, Dc= 1.109 g/cm3, Mr = 650.82, F（000） = 2832, andμ = 0.080 mm-1. The final R = 0.0765 and wR = 0.1736 for 15117 observed reflections （I 〉 2σ（I））. The molecular crystal structure of pedunculoside shows relative stereochemistry of 3β, 19α,23-trihydroxy-urs- 12-en-28-oic acid-28-O-β-D-glucopy- rainosyl ester. The molecule is composed of one glucopyranosyl ring and five six-membered rings with ring junctures of A/B trans, B/C trans, and D/E cis. There are two C36H50O10 molecules in an asymmetric unit, and the title compound is stacked into a 2D layer structure through hydrogen bonds.

An HPLC Fingerprint Identification of Dried Barks of Ilex rotunda and Ilex godajam

[Objectives] A simple and reliable HPLC fingerprint method was developed for the identification of dried barks of Ilex rotunda and I. godajam. [Methods] Nine batches of dried barks of I. rotunda,and seven batches of dried barks of I. godajam collected from different pharmacies and arboretums in different regions of China were used to establish fingerprints. The software Similarity Evaluation System of Chromatographic Fingerprints of Traditional Chinese Medicine( 2004 A Edition) was used to evaluate the fingerprints. [Results]The fingerprints of dried barks of I. rotunda and I. godajam were established. Methodological study met the technical requirements of fingerprints. The similarities of the fingerprints of dried barks of I. rotunda and I. godajam were all more than 0. 8 and 0. 9 respectively. There were 31 and 28 common peaks in I. rotunda and I. godajam,which could be classified into two clusters by principal component analysis( PCA) and hierarchical cluster analysis. [Conclusions] The feasibility and advantages of used HPLC fingerprints were verified,and the results indicated that the HPLC fingerprint as a characteristic distinguishing method combining similarity evaluation,principal component analysis and hierarchical cluster analysis can be successfully used to identify the authenticity of dried barks of I. rotunda and I. godajam.
