The results showed that, NO-3-N contents and nitrate reductase activity had obvious diversity in different spinach varieties and different organs of the same plant. The NO-3-N contents in stem were the highest, followed by petioles, then mesophylls, and were the lowest in roots. When the ratio of root to shoot was higher, the NO-3-N contents in plants were lower. NR activity was higher in root especially in lateral root. The NO-3-N contents in mesophyll and petiole were negative correlated with the in vitro -NR activity and in vivo -NR activity in roots.

Results The activity, recovery rate of activity and half-life of immobilized SOD were 333 U/g, 86.32% and 43.8 d respectively. After storage at room temperature for 5 d, the relative activity of SOD was still more than 80%. The optimal reaction temperature of immobilized SOD was 45℃, and the activity retentions after being used for the first and second times were 70.12% and 51.72% respectively. Both the optimal pH values for SOD before and after immobilization were 6, while the Km values were 0.16 and 0.18 mmol/L respectively.

结果 固定化超氧化物歧化酶活力为333U/g，酶活回收率为86.32%，半衰期为43.8d；固定化酶室温保存5d后，相对酶活力仍保持在80%以上，最适反应温度为45℃，使用一次后回收率为70.12%，重复使用两次后回收率为51.72%；固定化酶与溶液酶在pH6时活性最强，Km分别为0.18mmol/L和0.16mmol/L。

As the necessary choice of modern cultural creation, self-conscious symbol design always emerges as a specific cultural creation activity by human dealing with the relation to the outside objective symbolic world under specific historical conditions, which is a functional transcendent activity, a programmed cultural creation activity seeking for concreteness against abstractness, and it is also a cultural creation activity with self-discipline, compatibility, and pre-examination value with the ability of self-reflection, self-criticism, self-transcendence and self-creation, therefore, it is a choice of cultural practice which is helpful for us to guide contemporary human cultural creation according to complex situations and it is also one to further control the future and development trend of our culture.

摘 要：作为现代文化创造之必然选择，自觉符号设计在具体历史条件下总是表现为人处理同外界客观符号世界关系的特定文化创造活动，它既是一种功能性超越活动，又是一种不断寻求具体、反对抽象的程式化文化创造活动，还是一种兼顾自律性、兼容性与预验性价值的文化创造活动。它具备自我反省、自我批判、自我超越、自我创造能力，有助于我们按照复杂情况来引导当代人类文化创造，更好地把握自身文化未来与发展趋势。

This research utilized the method of organic synthesis, researching different amounts and positions of hydroxy-substituted benzoic acid and serotonin into amide reaction, so as to produce a series of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10). Accordingly, this study conducts the following four tests. I. The activity of antioxidant and the experiment of ability to scavenge DPPH free radical, II. The ability of overall antioxidant—the activity of TEAC, III. The activity test of inhibit Tyrosinase, and IV. The study of absorbing UV / VIS Spectrophotometers. This study use trolox, arbutin, and octyl salicylate as the control groups, and to test the ability of anti-oxidation, the activity of inhibit Tyrosinase, and the ability of absorbing UV. This research ultimately intends to investigate the applied value of those compounds into cosmetics.
