中国素馨属的数值分类

 A numerical taxonomic study of Chinese jasminum is presented. The 57 OTUS includemost taxa of the genus in China. Sixty eight characters, of which 30 were quantitative and 38 were qualitative, were used in the numerical analysis. The methods used here are cluster analysis and principle component analysiis (PCA). In cluster analysis, product-moment correlations secured from standardized data were clustered by the unweighted pair-group method using arithmetic average linkage (UPGMA). From the evidence presented the genus is divided into two sections which correspond to the two groups proposed by Taylor in 1945, rather than the four sections established by De Canolle (1844). By techniques of numerical taxonomy, some doubted taxa such as J. humile L., J. girddii Diels, J. ligustrioides Chia, J. hemsleyi Yamamoto J. cinnamomifolium var. axillare Kob.  … are re-examined and the treatment of these taxa are further discussed.

穿心莲内酯对小鼠肝细胞色素P450的影响

目的:研究穿心莲内酯对小鼠肝细胞色素P450的影响。方法:小鼠给药穿心莲内酯或3-甲基胆蒽后,分别测量小鼠肝脏内P450酶的总含量、CYP1A1/2的活性和蛋白表达等指标。结果:穿心莲单独给药时,对CYP1A1/2的活性及蛋白表达没有影响。穿心莲内酯和3-甲基胆蒽联合给药时对CYP1A1/2的活性呈诱导作用,同时CYP1A1/2的蛋白表达均显著高于空白对照。结论:穿心莲内酯与3-甲基胆蒽联合用药时对小鼠肝P450的活性及蛋白表达均显示出一定的调控作用。

裂瓜属的研究

The classical and numerical taxonomy, palynology and the geographical dis- tribution of the Genus Schizopepon are dealt with in the present paper.  Having comme- nted on various opinions regarding the systematic position of the genus, the present au- thors consider that C. Jeffrey’s treatment of Schizopepon as a new and monogeneric tri- be, Schizopeponeae, should be supported.      The gross morphological characters in the genus are assessed from the taxonomic point of view.  Some characters, such as stamens with an elongated connective or not, different insertions of ovules and various forms of ovaries and fruits, may be used for distinguishing subgenera.      The pollen grains of all the species were observed under light microscope (LM) and scanning electron microscope (SEM).  The results show that a strong differentiation has taken place in the pollen of the genus, and in consequence it may be regarded as an important basis for dividing subgenera and species. Especially it should be pointed out that degrees of development of colpi and positions of ora are positively correlated with the external characters used for distinguishing subgenera.      According to the morphological and palynological characters, the genus Schizopepon may be divided into three subgenera and eight species: 1. Subgenus Schizopepon: 5 spe- cies, S. bryoniaefolius Maxim., S. monoicus A. M. Lu et Z. Y. Zhang, S. dioicus Cogn., S. longipes Gagnep. and S. macranthus Hand.-Mazz.; 2. Subgenus Rhynchocarpos A. M. Lu et Z. Y. Zhang: 1 species, S. bomiensis A. M. Lu et Z. Y. Zhang; 3. Subgenus Neoschi- zopepon A. M. Lu et Z. Y. Zhang: 2 species, S. bicirrhosus (C. B. Clarke) C. Jeffrey and S. xizangensis A. M. Lu et Z. Y. Zhang.      The 8 OTU’s including all the species of this genus and 31 characters, of which 16 are morphological characters and 15 palynological characters, were used in the numerical taxonomic treatment.  After standardization of characters, the correlation and distance matrices were computed.  The correlation matrices are made to test the various clustering methods.  At last, the UPGMA clustering method was selected and its result is shown in the form of phenogram.  The result of numerical analysis is similar to that of the classical classification.      Schizopepon Maxim. is a genus of East Asia-Himalayan distribution. China has all 8 species and 2 varieties, of which 6 species are endemic. Based on the statistics of spedies number, the distribution centre of the genus is considered to be in the Hengduan Mountains (Yangtze-Mekong-Salwin water divides) and the adjacent areas of the southwest China.

RAPID DETERMINATION OF GUANINE BY HIGH PERFORMANCE CAPILLARY ELECTROPHORESIS

A simple and reproduciable method for determining guanine by high performance capillary electrophoresis is presented. The method involved the use of 2-amino-5-mercapto-3,4-dithiazole as internal standard and 40mmol/L borax-H3PO4 (pH2)-5% EtOH as.the background electrolyte. The result showed that the linear range for guanine is 5-300 mg/L with the recovery of 94%-98% , the detection limit of 2. 80 mg/L and the RSD of 3. 1%. The satisfactory result was obtained when it was used to detect the concentration of guanine in acyclovir product.
