During this years, TCM has a prominent effect on Dysfunctional Dyspepsia,so we study the effect of SiNiSan of soup on the Dysfunctional Dyspepsia sharply from the ability of stomach emptying and the ability of intestines pussing on the normal Kunming rats by the coloring matter,and the chang of the nerve fiber, nerve qualitative, on the stomach organize of normal SD ratsMethods:In the experiment, the thirty Kunming rats, whose avoirdupois are about twenty grammes,and thirty S. D rats, whose avoirdupois are about two hundred grammes,were randomly divided into three groups, 0. 9yS group, SiNiSan of soup group and Mosapride Citrate group.

This research take late-maturing variety adzuki bean Jihong-4 as the experiment material, After the photoperiod inducement at different leaf ages treatment, the result showed that the activity of NR under LF treatment is higher than CK treatment on the whole, and is lower than SD treatment; The content of the dissociation amino acid under these three treatments show a descend trend along with the leaf ages accretion, but the inducement increasing the content of dissociation amino acid, different leaf ages leaves show some difference, and alternating rise with SD treatment; Inducement can reduce the content of soluble sugar, and continuous inducement shows a accumulation effect; 2LF is the most sensitivity stage for soluble protein under photoperiodic inducement, From this stage, each leaf indumenta can reducing the content soluble protein, but continuous inducement reducing rising it.

本研究通过光周期诱导的方法，对中晚熟品种冀红4号红小豆进行不同叶龄进行处理，结果表明：所有叶龄处理下硝酸还原酶活性基本高于自然光处理而低于连续短日照处理下的；随着叶龄增大，各处理游离氨基酸总量均呈下降趋势，但光周期诱导可提高游离氨基酸含量，不同叶龄表现有所差异，与连续诱导交替上升；诱导可降低可溶性糖的含量，并连续诱导出现累积效应；2LF是光周期诱对可溶性蛋变化最敏感的时期，这个时期起单个叶龄诱导可降低可溶性蛋白含量，但连续诱导却可提高；LF处理下的类胡萝素总体含量高于另两个处理，而LF处理下的叶绿素含量在仅3叶龄前高于CK处理下的，随后出现下降趋势。
