| 2. | Preparation of avermectin granular coated with polymer diatomite composites and its properties
硅藻土为控释材料的阿维菌素颗粒剂的制备及其性能研究 |
| 3. | The method for determining avermectin bu ( avm ) in freshwater by high - performance liquid chromatography with fluorescence detector was established
建立了阿维菌素在淡水中含量的高效液相色谱荧光检测法。 |
| 4. | Furthermore , it produced 2 unusual components d24 - 1 and d24 - 2 . it was basically confirmed , by hplc and ms , that d 24 - 1 was oligomycin a ; while d24 - 2 was 5 - oxo - avermectin la
此外，该菌株还产生两个异常的组分d24和d242 ，经hplc及质谱进一步分析，初步确定异常组分d241为寡霉素a ，而d24 2为5 |
| 5. | The effects of various mutagenic agents on the productivity of avermectin by slreplomyces avermilitis were evaluated in this work . three different mutagenic breeding methods were developed , such as ntg , uv , ion implatation
在育种研究中应用了离子注入、亚硝基胍和紫外线诱变方法，并对这几种诱变方法进行了比较，发现离子注入的诱变效果最好。 |
| 6. | The method for determining avermectin ( avm ) in muscle of sturgeon ( a . schrenckif ) by high performance liquid chromatography with fluorescence detector was established . the homogenized muscle sample was extracted by acetonitrile , following centrifugation at 3000 g for 15 min
采用乙腈作为肌肉中蛋白沉淀剂和阿维菌素的提取剂，经碱性氧化铝spe柱纯化，蒸干和衍生化，用高效液相色谱( hplc )检测。 |
| 7. | A rapid uptake of avermectin b1a was observed and steady - state levels were reached within 14 to 18 days . depuration of avermectin bia residues in muscle of sturgeon was relatively rapid with more than 50 % clearance occurring after about 4 - 6 days in control water
Avmb _ ( 1a )在鲟鱼体内的残留消除比较迅速，大约经过4 - 6天的消除期，体内残留量大约消除50 ；经过14 - 18天的消除期，体内残留量消除超过95 。 |
| 8. | According to pet fur features to a variety of imported raw materials , and in particular to add advanced international eliminate mites kill ticks prescription - avermectin , the effective elimination of various ectoparasite prevent mites , ticks infections of the skin and eliminate mites kill ticks excellent results
根据宠物皮毛特点，选用多种进口原料，并特别添加国际先进灭螨杀蜱配方?阿维菌素，能有效灭除各种体外寄生虫，防止螨、蜱引起的皮肤感染，灭螨杀蜱效果极佳。 |
| 9. | 281 double crossover mutants were examined by fermentation experiments and hplc analysis for production of polyketides . besides avermectin b1a and b2a , a new compound ( about l ~ 4ug / ml ) which showed a retention time and fragmentation patterns identical to those of the authentic sample of 22 , 23 - dihydroavermectin bla by hplc and lc / ms analysis were detected in culture extracts of 27 isolates
在筛选的281个双交换突变株中，有27株除了产生阿维菌素b1a和b2a ，还产生一个新组分，经hplc和lc ms分析，证实该组分为c - 22 ， 23双氢阿维菌素b1a (即伊维菌素b1a ) 。 |
| 10. | Compounds with bcf values < 100 are considered to be of little environmental concern and not expected to bioconcentrate into tissues . in this in vivo test , the low uptake of avermectin b1a and its low persistence in sturgeon muscle demonstrate that it will neither bioaccumulate in individual organisms nor biomagnify in the food chain
在试验中，鲟鱼对水中的avmb _ ( 1a )摄取率较低， avmb _ ( 1a )在鲟鱼体内消除迅速，以及avmb _ ( 1a )较低的bcf值，表明不易在水生生物食物链中被生物浓缩，不易在水生生物体内富集，对环境和人类的健康影响较小。 |
