    Yongfu ZHANG;Dingkang WANG;Yanfen NIU;Shengjing PENG;

    [Objectives] The research aimed to study the differences of pigment and nutrient substance contents among Impatiens L. strains with different flower colours. [Methods] Nine Impatiens L. strains with different flower colours were used to examine the contents of pigments,non-structural carbohydrates and titratable acids of petal,leaf and stem by pot experiment,and their relativity was analysed. [Results]The redder the petal,the higher the anthocyanin content,with significant difference. The contents of flavonoid and total phenol in orange,light red and white petals were significantly lower than that of cardinal colour system of petal. The contents of carotenoid in pink,pale red and purplish red petals were significantly higher than that of other colour system of petal. But anthocyanin content was low in purple petal,meaning that main pigment in purple petal might not be anthocyanin. Moreover,a small amount of anthocyanin was detected in leaf and stem,and its content was higher in the strain with redder flower. Chlorophyll a content of leaf had no significant among test materials,whereas the contents of chlorophyll b and chlorophyll( a + b) of leaf from red petal strains were significantly higher than that of white and pale red strains. By correlation analysis,it was found that soluble sugar content of petal had significantly positive correlation with anthocyanin content; flavonoid content had significantly positive correlation with the starch and titratable acid contents of leaf,whereas showed very significant negative correlation with soluble sugar content of leaf. Relativity between total phenol and titratable acid was significant positive correlation in petal,and relativity between carotenoid content of petal and titratable acid content of leaf was very significant positive correlation,whereas showed very significant negative correlation with starch content of stem. [Conclusions] The research could provide theoretic basis for development and utilization of Impatiens L.

    Bochao LI;Bo LI;Yun TENG;Chunlin LIU;Yuan LIU;

    [Objectives] By clustering analysis of tissue distribution data of brucine and strychnine in gastric ulcer model rat,the impact of Zuota on tissue distribution of basic components was studied. [Methods] Based on system clustering method of SPSS19. 0 statistical analysis software,using inter-group join method and squared Euclidean distance,brucine and strychnine contents of different tissues and organs in nonZuota group and Zuota group were taken as characteristic variables for clustering analysis,and phylogenetic tree was established. [Results]When clustering distance was 1,( i) taking brucine content as the index,there were three kinds of convergences in non-Zuota group. A1class: skin,liver,epididymis and jejunum; A2 class: brain and uterus; A3 class: testis and muscle. Brucine contents of the three classes showed as A1 < A2 < A3. There were two classes of convergences in Zuota group. B1 class: jejunum,epididymis,kidney,brain,skin and uterus; B2 class: muscle and( bottom) submandibular gland. Brucine contents of the two classes showed as B1 < B2.( ii) Taking strychnine content as the index,there were three classes of convergences in non-Zuota group. C1 class: muscle,testicle and oarium; C2 class: heart and lung; C3 class: uterus and liver. Strychnine contents of the three classes showed as C3 < C1 < C2. There were two kinds of convergences in Zuota group. D1 class: kidney and heart; D2 class: brain tissue and uterus. Strychnine contents of the two classes showed as D1 > D2. [Conclusions]When clustering distance was 1,low-content tissues and organs firstly clustered,and its toxicological effect( or pharmacodynamic action) was insignificant,and this kind of tissues and organs were relatively safe. A1 class and A2 class in Zuota group were merged into B1 class,in which liver was replaced by kidney. It illustrated that Zuota could decline the toxicity of kidney,and enlarged the safe action range of brucine. Kidney and heart in C2 class were clustered into D1 class,and average strychnine content in C2 class was higher than that of D1 class. It could be deduced that Zuota had the effect of protecting heart.
