ResultsOne hundred and thirty-one kinds of chemical constituents in micro-milling of Poria Cocos were separated ; of which sixty-seven compounds representing 51.145% of the oil were characterized. Relative contents that were more than 2% were determined as Nonanal 2.058%,Camphor 2.401%,2,3-dimethyl Decalin 3.819%,trans-Nerolidol 2.266%,Farnesol 3.322%,α-Cedrol 7.936%.

Two novel"black"dyes KRu〓(ttp-COOH= 4'-p-COOH-phenyl-2, 2', 6', 2-tpy) and trans-Ru (4, 4'-dcbpy)〓〓 were synthesized, their photophysical properties in solutions and photo-electric properties adsorbed on the surface of nanocrystalline TiO〓 were studied.

研究了两个"黑色"染料trans-Ru(4，4'-dcbpy)〓〓和KRu〓(ttp-COOH＝4'-p-COOH-phenyl-2，2'，6'，2-tpy)的光物理性质及其在纳晶TiO〓薄膜电极上的光电转换性质，二者在红光区的光谱响应范围均比cis-Ru(4，4'-dcbpy)〓〓的宽，能吸收大部分的太阳光，确实在长波区增加了光谱的敏感性。

Objective To investigate the effect of excessive all-trans retinoic acid on mouse embryonic palatal fusion and the mechanism.

We discovered that the best stereoselectivity of the Pictet-Spengler (cis/trans=92:8) was obtained, when the reaction of D-tryptophan methyl ester II-33 with piperonal II-34 in acetic acid was catalyzed by benzoic acid at room temperature.

我们发现室温下在冰醋酸中，D-色氨酸甲酯II-33和胡椒醛II-34在苯甲酸催化下，发生Pictet-Spengler反应的立体选择性最高， cis：trans的比例为92： 8。

The Pictet-Spengler reaction of D-tryptophan methyl ester hydrochloride II-42 with piperonal II-34 in various solvents was extensively studied. The best stereoselectivity (cis/trans=99:1) was obtained using nitromethane or acetonitrile as the solvent.

我们研究了在不同溶剂中，D-色氨酸甲酯盐酸盐II-42和胡椒醛II-34发生的Pictet-Spengler反应的立体选择性，发现当分别用硝基甲烷和乙腈做溶剂时反应的立体选择性达到最高， cis：trans的比例为99： 1。

Results showed that antioxidant activity of Dunaliella salina was similar to all-trans-carotene.

The present invention constructs anenterous adenovirus carrying trans-activator expression cassette and anticancer gene expression cassette.

本发明构建了携带有反式作用元件(trans-activator，TA)表达盒以及抗癌基因表达盒的无肠腺病毒或AAV。

E. methyl jasmonate +methyl salicylate, MeJA +cis-hexenal, MeJA +trans-hexenal, MeJA +benzothiazole, and then the induced activities of three defensive enzymes including peroxidase, polyphenol oxidase and phenylalanine ammonia lyase were measured.

以1年生合作杨扦插苗为试验材料，利用茉莉酸甲酯分别与水杨酸甲酯、顺式己烯醛(cis-hexenal)、反式己烯醛(trans-hexenal)和苯骈噻唑混合的4种挥发物熏蒸合作杨叶片，检测过氧化物酶、多酚氧化酶及苯丙氨酸解氨酶3种防御酶的活性变化。

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.

合成了以含硼基团为电子受体，以二甲胺基为电子给体，以苯乙烯基噻吩为共轭桥的新化合物2-[（4'-N，N-二甲胺基）苯乙烯基]-5-二米基硼-噻吩 trans-2-[(4'-N， N-dimethylamino) styryl]-5-dimesitylboryl-thiophene（简写为DMASBT，5）。X射线衍射方法测定其单晶结构表明，硼原子与π共轭桥之间的硼碳键相对于其它的硼碳键明显缩短，硼与π共轭桥之间存在除了σ键之外的p-π共轭作用。
