Whenpyridine was used as reductive decomposing agent, the expecting cholest-4-en-3,6-dione-22-al was obtained. However, when Zn/HOAc was used to decomposethe ozonide, C-4,5 double bond was further reduced to give cholest-3,6-dione-22-al as main product. 2 For the side-chain construction of compound (1), the solid-liquid phase-transfer Wittig reaction was used. When (3-methyl-2-oxobutyl)-triphenylarsonium bromide was used as reagent, the reaction can be carried out inmild reaction condition and the yield is higher than that when phosphorane wasused.

但使用Zn／HOAc作为分解剂时，却得到其氢化产物胆甾-3， 6-二酮-22-醛；2在甾体支链引入过程中，采用固-液相转移Wittig反应的方法，用(3-甲基)-2-氧丁基三苯基溴化胂作为试剂，反应在非常温和的条件下便可完成，而且产率比传统采用膦烷的方法更高；3在对某些甾酮化合物的选择性还原反应研究时，发现在〓还原体系中，当加入某些金属离子后，反应有更好的区域选择性和立体选择性。

Methods Blood samples were collected from the precaval vein of 6 female Tibet mini-pigs to test the concentration of sex hormones including T,P4,E2,FSH,LH,PRL and blood biochemical indexes including Ca, Mg, P, ALP, Cre, CHO, TP, and Alb during the estrous cycle.

对6头雌性西藏小型猪在发情周期内的发情当天、第5天、第10天、第15天、再次发情时分别采血5 mL并分离血清，应用放射免疫法测定血清睾酮、孕酮(P4)、雌二醇(E2)、促卵泡生成激素、促黄体生成激素、泌乳素；用自动生化仪测定血清钙、镁、磷、碱性磷酸酶、肌苷、总胆固醇、总蛋白、白蛋白。

Objective: To study the effects of progesterone on action potential of isolated rabbit sino atrial node cells.

The total synthese three natural compounds to explore enantioselective synthesis of flavanol: We use phloroglucin and 2, 4, 6-trihydroxyacetophone as starting materials to synthesis distenin in two ways; Resorcin was used to synthsis 2, 5-dimethoxymethoxyacetophone though 3 steps.

对黄烷醇化合物的立体选择性全合成进行了探索：以间苯三酚和2，4，6-三羟基苯乙酮为原料，尝试用两条路线对Distenin化合物进行了全合成研究；以对苯二酚为原料，经三步制得2，5-二甲氧甲氧基苯乙酮，与2，4，6-三甲氧甲氧基苯甲醛反应，经四步反应得到天然产物3，5，7，2′，5′-二五羟基黄烷关键中间体1-（2′，6′-二甲氧甲氧基苯）-3-（2"，4"，6-三甲氧甲氧基苯）丙烷-1R，2R-二醇83及其对映体84；简要介绍了EGCg类化合物的生物活性和研究概况。

Acetylenic ketone promise physiological performance is the human body generated by the first body progesterone ketones 4-8 times.

Glycerolgenesis. Organic acids was mainly produced during growth phase, acetic acid was the highest, about 1. 6g/L. When the amount of acetic acid and α-Keto glutaric acid was increased slightly and others decreased a bit in 〓 process. The kinds and amount of arganic acide during microbial glycerol production in C.

有机酸主要是菌体生长过程产生的，在酵母生长达平衡期时乙酸积累达最高值1.6g/L，乳酸、丙酮酸、酮戊二酸、苹果酸也都达较高浓度，此时相应的pH降低至最低，随着发酵进行其中乙酸和酮戊二酸略有增加，而其它有机酸是减少的。

The patients whose progesterone in blood of early trimester of pregnancy below 63.6 nmol/L have more chances of abortion, the treatment with progesterone and chorionic gonadotropic hormone can improve the pregnancy outcome and decrease the occurrence of abortion.
