For the first time, enantiomers of C2-symmetric 1,1 -spirobiindane-7,7'-diol were resolved with crude menthyl chloroformate by phase-transfer catalysis in the presence of tetrabutylammonium bromide. The reaction was carried out at 0℃-rt. The diastereomers of SPINOL bis-menthyl carbonate can be separated by simple crystallization using alcohol. The hydrolysis of the diastereomers was carried out via aqueous NaOH/EtOH solution.

A method based on capillary electrophoresis with electrochemical detection has been developed for the separation and determination of epicatechin, kaempferol, chlorogenic acid, 4-hydroxybenzoic acid, quercetin and protocatechuic acid in hawthorn for the first time.

首次采用毛细管电泳—电化学检测法同时测定山楂中的6种活性成分：表儿茶素，山奈酚，氯原酸，4-羟基苯甲酸，槲皮素和原儿茶酸的含量。

Personality traits were evaluated by Eysency Personality Questionnaire that was compiled by Eysency and revised by Gong. Standard scores of Psychoticism, Extraversion and Neuroticism were calculated, and taking 50 points as a boundary. Each dimension was assigned into 2 grades non-psychotic type (P0) psychotic type (P≥50), introversion type (E0), extraversion type (E0), non-nervous type (N0) and nervous type (N≥50). 5 mL ulnar vein blood was obtained without adding decoagulant, and then serum was removed. Genome DNA was extracted from blood clot by conventional chloroform for PCR analysis. PCR product was sequenced by pyrophosphoric acid. SNP was determined by PSQ96 MA sequenator. Allele frequency was analyzed by mass spectrometry.

人格评定采用Eysency编制，龚耀先修订的艾森克人格问卷、计算精神质，内外问，神经质3个个性维度的标准分，并以50分为界，将各维度分为两个等级：非精神病倾向型（精神质0）、精神病倾向型（精神质≥50）；内倾型（内外向0），外倾型（内外向≥多50）；非常经质倾向型（神经质0），神经质倾向型（神经质≥50）取肘静脉血5 mL，不加抗凝剂，弃血清，血凝块常规酚氯仿提取基因组DNA，进行PCR分析PCR产物应用焦磷酸测序PSQ96 MA测序仪进行SNP检测，用质谱法进行及等位方基因频率分析。

DHCC Constance in the chemistry belongs to the onlighted Cyclopentanoperhydrophenanthrene when it reacted together with the acid Constance it could transform into the fluorescence phenol.we did the flouric determination for the DHCC, in which treated by the ethanol-sulfuric acid or acetic anhydride-methylene chloride-sulfuric acid, acquired standard curve in the 0-40μg/ml presented the liner relet...

DHCC类物质在化学上属于不发光的环戎烷多氢菲类，但与酸性物质一起反应时，可转化为产生荧光的酚类。用乙醇硫—酸或乙酸酐—二氯甲烷—硫酸处理后的DHCC进行荧光检测，获得标准曲线0—40μg/ml范围内呈线性关系，检出的最高灵敏度可达300ng/ml。该方法可用于分离后的DHCC及单一种DHCC代谢物的定性及定量分析。

Trace Ru could sensitively catalyze the fading reaction of chlorosulphophenol azo rhodanine with KClO3 in H2SO4 medium in water bath at 85 ℃, and the fading level was in direct proportion to Ru in certain content range.
