草酸

The essence of higher heating temperature for oxalate precursor is pockety La(superscript 3+) and Zr(superscript 4+).

草酸盐前驱体中镧和锆两种成分局部的分布不均匀是造成其处理温度比氨水法要高的直接原因。

Glycyrihizic acid can cause the polarigraphic catalytic wave of oxygen. GA scavenging superoxide ion is demonstrated chemically by the catalytic wave at molecular lever.

本文报道的甘草酸及其皂甙类衍生物存在下的氧极谱催化波，从分子水平研究了GA清除超氧离子自由基〓的化学作用机制，证实清除〓的活性基团是GA分子中与C＝O基共轭的C＝C双键，并非-OH基，纠正了文献观点。

However, there were no significantly differences on serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase between these four groups.

然而在肝功能方面，不论是血清麸草酸转胺基酶或血清麸丙酮酸转胺基酶，四组都没有显著性的差异。

The main organic acid was citric acid, followed by malic acid. Citric acid and tartaric acid levels increased during storage. Malic acid and quinic acid increased from stage one to stage two. Shikimic acid level increased from stage one to stage three, then decreased slightly. Acetic acid changed unremarkably. Succinic acid changed not significantly from stage one to stage two, then increased and it was the highest in the stage three. The level in stage four and stage five was lower than the level in stage three.

五九香梨果实中的主要有机酸是苹果酸和柠檬酸，整个贮藏期间，柠檬酸和酒石酸含量处于上升趋势，苹果酸和奎宁酸含量在第一、二月贮藏期间增加，而后开始下降；莽草酸含量在贮藏期第一到第三阶段上升，而后略下降；琥珀酸含量在第一到第二阶段变化不明显，接着有上升的趋势，在第三阶段含量达到最高，第四和第五阶段略低于第三阶段；乙酸含量变化不明显。

High performance liquid chromatographyanalysis showed the mango fruit of these two cultivars contained 3 carbohydrates, 11 organic acids and 4 carotenoids. The carbohydrates were composed of fructose, glucose and sucrose; the organic acids were oxalic acid, tartaric acid, quinin acid, malic acid, ascorbic acid, lactic acid,α-ketoglutaric acid, citric acid, fumaric acid, succinic acid and gallic acid; the carotenoids were violaxanthin,β-carotene, lutein, lycopene.

高效液相色谱分析表明，芒果果实共含3种糖、11种有机酸和4种类胡萝卜素，即果糖、葡萄糖和蔗糖；草酸、酒石酸、奎尼酸、苹果酸、抗坏血酸、乳酸、α-酮戊二酸、柠檬酸、富马酸、琥珀酸和没食子酸；堇菜黄素、β-胡萝卜素、叶黄素和番茄红素。

The method of pH controlled homogenate extraction of carnosic acid in Rosmarinus officinalis was studied, and the optimum technology parameters were found as following: Homogenate once for 4 min with 80% ethanol (adjusted pH=3.0 with HCl) at a ratio of solid to liquid 1:12.

采用pH控制匀浆法从迷迭香枝叶中提取鼠尾草酸，研究了提取过程中不同影响因子对提取效果的影响。确定的匀浆提取优化条件为：以盐酸调节pH=3.0的80%乙醇为提取溶剂，料液比1：12，匀浆4min，匀浆提取1次。
