The result showed all the characteristic absorption peaks of hydroxyl-naphthaoquinone in the FT-IR spectrum of the product. The constituents of the product were determined by GC-MS to be: 1, 4-naphthaoquinone, 5-hydroxy-1,4-naphthaoquinone and 7-methoxy-1-tetralone, and the content of juglone in the product was 96.42%. The structure of juglone in the product was confirmed by 1H NMR. This study offered a simple and effective method to get high purity juglone from bark of J. mandshurica.

分别用FT-IR表征了产品的有机官能团、用GC-MS分析了产品的化学组成和产品中胡桃醌的相对含量（GC含量达96.42%）、通过1H NMR确认了产品的胡桃醌结构本研究提供了一种从核桃揪树皮中简便快捷地提取制得高纯度的胡桃醌产品的方法。

The soil and bark samples collected from Yunnan, Hebei and Shanxi provinces of China, and also from Vietnam, were used as the materials in this experiment. And dung pellets of rabbits or goats that had been autoclaved can be used to induce many kinds of fruiting bodies of the Myxobacteria in different colors, sizes, and shapes. We isolated and purified Myxobacteria strains with the improved method which was found by our laboratory.

本实验以采集自越南以及我国的云南、河北、陕西各地的土样和各种树皮、腐木作为实验材料，利用兔、羊粪球和滤纸作为基质诱导出多种颜色丰富、形态多样的粘细菌子实体，采用本实验室摸索出的较为有效的纯化粘细菌的方法，在实验器材上用24孔细胞培养板代替传统的平皿，有效地缩短了粘细菌的纯化周期，提高了分离纯化的效率。
