查询词典 extracting

But pancreatin is a mixtrure of various enzymes, each enzyme has a low purity and many enzymes have similar molecule structure and physicochemical properties, when extracting one enzyme, it is easy to abandon the otherone as impurity. This is why there are few technoloies of stimutaneous extraction of more than three enzyme from pancreatin and all the technoloies have shortages.

但是由于胰酶为多种酶的混合物，每种酶的纯度很低，许多酶又具有相似的分子结构和理化性质，因此往往在提取一种酶的同时，其它酶被当作杂质处理掉了，这就导致了胰酶中三种以上酶联产的工艺极为少见，而且已有工艺都有各自的不足。

Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55～50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55～44.19% and Mn of HCl-extractable species were 20.66～28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5. Chlorophyll in leaves of Polygonum hydropiper L.

不同的提取剂对水蓼根、茎、叶的提取结果表明，随着锰处理浓度增加，水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化，说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加；在茎中，水提取态锰含量占总锰的34.55-50.26%，且随锰处理的增加其水提取态锰的比例增加，这有利于锰向上运输；水蓼的叶片中，水提取态锰占总锰的38.55-44.19%，盐酸提取态锰占总锰的20.66-28.74%，说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。
