Polyalcohol,preservative,metal ion and carbohydrate were experimented through single-factor tests,potassium sorbate,Na~+、K~+、Ca~(2+)、sucrose and lactose had great effects on the stability of mannanase M0710.Orthogonal experiments decided the optimal stabilizing agent were potassium sorbate 3%,sodium chloride 2%and sucrose 2%.

对突变酶M0710的稳定剂也做了初步研究，单一因素试验考察了多元醇类化合物、防腐剂、金属离子和糖类化合物等对目的酶稳定性的影响，其中山梨酸钾、Na~+、K~+、Ca~(2+)、蔗糖、乳糖对酶的稳定性有明显效果，通过正交试验最后确定效果最佳的液态酶M0710的稳定剂为山梨酸钟3%、氯化钠2%和蔗糖2%。

This method is highly sensitive and highly selective and was can be applied to the rutin、quercitrin、quercitrin-3-O-giucoside and quercitrin-3-O-galactose determination in yacon leaves with satisfactory result and also can be used to determine these flavonoids in Chinese herbal medicine and Chinese herbal and crude drugs preparations containing flavonoids.

该方法也可用于含芦丁型黄酮中草药及其制剂中芦丁、槲皮素、槲皮素-3-O-葡萄糖苷和槲皮素-3-O-半乳糖苷的检测。

On a ZORBAX Stable Bound (2.150 mm, 1.8 m), the rutin、quercitrin、quercitrin-3-O-giucoside and quercitrin-3-O-galactose could be separated completely with 0.05 mol/L potassium dihydrogen phosphate and methanol as mobile phase (40:60,V/V) at a flow rate of 0.3 ml/min and detected with a photodiode array detector .

在色谱柱为ZORBAX Stable Bound (2.150 mm， 1.8 m)，流动相为0.05 mol/L的磷酸二氢钾缓冲溶液-甲醇(40：60，V/V)，流速为0.3 ml/min，在检测波长为360 nm的色谱条件下，芦丁、槲皮素、槲皮素-3-O-葡萄糖苷和槲皮素-3-O-半乳糖苷分离效果好，方法灵敏度高，重现性好，用于测定雪莲果叶中的上述几种黄酮芦丁型黄酮，效果满意。

ObjectiveTo explore the effect of invigorating kidney-YIN recipe on the free radical metabolism and immune function of aging mice induced by D-gal.

目的研究滋补肾阴方药对D-半乳糖所致衰老小鼠自由基代谢及免疫功能的影响。

Raffinose family oligosaccharides have been proposed to play roles in the acquisition of desiccation tolerance in seeds, seeds viablity, and cold acclimation in plant.

中起重要作用。本文从种子的脱水耐性获得、植物的冷驯化、细胞内定位及生物合成等方面综述了棉子糖半乳糖苷系列寡糖的研究进展。

Seed was stored in a storage temperature, the galactose content of seed decreases as the seed moisture content decrease. However, the glucose, fructose, sucrose and raffinose content of seed increase as the seed moisture content decreases, but this kind of change is not clear if seed was stored at lower temperatures ranges from 20℃ to -18℃.

然而葡萄糖、果糖、蔗糖和密三糖的结果与半乳糖的变化趋势相反，随着贮存温度的升高，四种糖的含量逐渐下降，在同一贮藏温度条件下，随含水量的降低，这四种糖的含量却逐渐升高，但在贮存温度较低时(20℃和-18℃)，这种变化趋势不明显。

The result demonstrated that mannitol was the best protective substance, followed by raffinose,trehalose and melibiose, L-cysteine, xanthan gum and glycerol showed slightly protective ability.

结果表明，甘露醇对α-半乳糖苷酶的保护效果最好，其次是棉籽糖、海藻糖和蜜二糖；L-半胱氨酸、黄原胶和甘油也起到了较好的保护作用。

The lac operon is an inducible operon, whereas the trp operon is a repressible operon.

乳糖操纵元是可诱导的操纵元；色氨酸操纵元是可阻遏的操纵元。

They were separated by using DEAE-cellulose column chromatography. Their structures were determined by IR and GC-MS. The contents of the total polysaccharide, 3,6-anhydrogalactose and sulfate were analyzed by the methods of anthranone-sulfuric acid, resorcin and BaCl2 turbidimetry.
