    Le LI;Xianghui SU;Hui TANG;

    [Objective] To extract and isolate the effective components from Sorbus tianschanica,and to research the hypoglycemic effects of n-Butanol part. [Methods]S. tianchanica was extracted by reflux extraction. After gradient elution,n-Butanol part was obtained. With diabetic mice induced by STZ as the model,blood glucose test was carried out. [Results]n-Butanol part in administration group had significant differences in hypoglycemic effects with that in model group(P < 0. 05),showing that n-Butanol part had certain antidiabetic functions on diabetic mice induced by STZ. And the hypoglycemic effects showed a reducing trend as the administration dosage decreased,indicating that administration dosage had positive correlation with hypoglycemic effects. n-Butanol in different parts could reduce the blood glucose of diabetic mice in different degrees. And the blood glucose value in high-dosage group(8 g /kg) reduced greatly at 2 h after administration,having great differences with that in model group(P < 0. 01). This showed that high dosage was helpful to the glucose tolerance of diseased mice,and could effectively protect against the rapid increase of blood glucose after meal. n-Butanol had no significant effects on the blood glucose of normal mice. However,the morality rates in high-and middle-dosage groups were both higher than that in low-dosage group; and the morality rate in administration group was lower than that in model group,showing that n-Butanol could promote the survival rate of diabetic mice. [Conclusions]S. tianchanica had certain effects of anti-diabetes.

    [Objective] To inspect the influence of Veratrum Nigrum on the body resistance strengthening function of Panax Ginseng with different proportion and dosages. [Methods] ICR mice were divided,according to their weights,into normal group,model group and Panax Ginseng group of different dosagess. Immunocompromised mouse were constructed by intraperitoneal injection with cyclophosphamide(45 mg/kg,qod × 3). Medicines were administrated since the first day of modeling,once per day for 7 days in total,so as to find out the effective dose range of Panax Ginseng. With uniform design and medicine administration with 2 factors 11 levels,observing the influences of different proportions and dosages of combined decoctions of Panax Ginseng and Veratrum Nigrum through the index of immune organs(spleen and thymus),ability of carbon clearance and blood routine of the modeling mice. [Results]Comparing with the mice in nnormal group,ones in modeling group had obvious reduction in the body mass,visceral index,phagocytic function and blood routine. Splenic index,phagocytic correction index,WBC,RBC and Hb increased significantly with only using Panax Ginseng(0. 5- 8. 0 g /kg). Evaluation of the influence of Veratrum Nigrum on the body resistance strengthening function of Panax Ginseng based on uniform design:(1) Influence on the index of immune organs:Decoctions(Veratrum Nigrum + Panax Ginseng 0. 53- 8. 05 g /kg) had no obvious effect on the index of immune organs of immunocompromised mice.(2) Influence on the ability of carbon clearance: Veratrum Nigrum could reduce the ability of Ginseng to enhance the phagocytic function(Panax Ginseng∶ Veratrum Nigrum < 100 ∶1) in direct proportion. The strongest antagonistic effect of Veratrum Nigrum would be achieved when the total dose of decoctions was 3. 08 g/kg(Panax Ginseng∶Veratrum Nigrum =9∶1).(3) Influence on blood routine: if Panax Ginseng∶Veratrum Nigrum <100∶1,the effect of Ginseng to increase WBC and RBC would be counteracted by Veratrum Nigrum(0. 034-0. 13 g/kg)without influencing the dose-effect curve of Ginseng. The strongest antagonistic effect of Veratrum Nigrum would be achieved when the total dose of decoctions was 4. 58 and 3. 48 g /kg(Panax Ginseng∶ Veratrum Nigrum = 9∶1). The effect of Ginseng to increase Hb would also be counteracted by Veratrum Nigrum but the dose-effect curve of Panax Ginseng would decline. [Conclusions]Within the dose range stipulated in the Pharmacopoeia,the body resistance strengthening function of Panax Ginseng may be reduced or counteracted by Veratrum Nigrum,and the intensity of effect changed with the imparity of proportions and dosages.

    Fan LIU;Zhigang YAN;Longhua BAI;Xiaojun MA;Ying WEI;

    [Objective] This study was to screen out a suitable colchicine treatment method for generating variation in calli of Siraitia grosvnorii. [Methods]Different concentrations of colchicine and treatment time were set to investigate the optimal callus induction conditions for Siraitia grosvnorii(Swingle) C. Jeffrey. [Results]With the increase of colchicine concentration and time,the calli died more and more seriously. The induction rate of mutated cells( polyploidy) was ascended along with the increase of treatment time and colchicine within a certain range. However,when the colchicine concentration exceeded a specific amount,the polyploidy induction rate was decreased. Treatment with0. 5 g /L colchicine for 48 h showed the best effect on polyploidy induction while the least damage on callus tissue. In comparison with the normal material,the mutated plants showed bigger leaves and slower growth,while the stomata did not change remarkably. By chromosomal analysis,the mutated material was preliminarily identified as polyploid. [Conclusions]Treatment with 0. 5 g /L colchicine for 48 h could well induce the generation of diploidy materials.
