The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.

实验部分采用以石油醚脱脂，甲醇为溶剂的回流提取法来提取植物多酚，用显色反应检识酚羟基；采用紫外分光光度法对多酚粗体物进行总多酚含量的测定；选取了聚生小穴壳菌、立枯丝核菌、梨叶点霉等10株常见农林业致病真菌，采用试管液基稀释法对多酚粗提取物进行了抗真菌活性筛选试验，并测定其最低抑菌浓度；采用柱层析法和薄层层析法对其中抑菌效果较好的龙血竭进行分离分析，根据其中3种化合物的光谱数据UV、IR、~(13C-NMR、1H-NMR和MS鉴定其结构。

A bacteriocin-like substance producing strain T12 was screened from 212 lactic acid bacteria isolated from intestine of healthy pigs by paper disk test and was identified as Lactobacillus. The supernatant of T12 exhibited strong inhibitory activity against the gram-positive bacteria, including Micrococcus lysodeikticus, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. A strong activity was also observed against the gram–negative bacteria and some eumycete, such as Escherichia coli, Salmonella typhimurium and Fusarium graminearum.

The antifatigue function of more than forty kinds of insect,fungi,bacteria and algae was studied and sifted first in this study by detecting swimming endurance and biochemical indexes. Then,in order to choose the better ones from the compoud additives formulas composed of L-carnitine, taurine, octacosanol,vitaminE and insectA ,a cross design experiment was done. InsectA was discovered in the first experiment that it greatly improved the antifatigue function in mice. Finally, the acute toxicities, thirty-day feeding effects and the mechanisms of No. 1 antifatigue compoud additives(No.1ACF) were studied.

本研究首先通过小鼠游泳耐力试验和血液生化指标的测定对40余种昆虫、菌藻的抗疲劳作用进行了筛选；在此基础上，应用正交设计方法对以L-肉碱、二十八醇、牛磺酸和本实验筛选出的抗疲劳功效较好的昆虫A为原料的配方进行了抗疲劳作用筛选，并对筛选出的最佳配方，即抗疲劳复方添加剂1号配方进行了小鼠急性经口毒性试验、30天喂养试验和抗疲劳作用机理研究。

The result indicates that there are one dominant and one recessive complementary gene that are effective against the Indian race 2E16. However, the monosomic analysis results indicated there was one resistant gene to the Indian race 2E16 and the gene was located on chromosome 3B. The current study shows that it is different from the known genes.
