柚皮素

The proposed method surpassed other chromatographic alternatives in terms of limit of detection at least 10~3 folds with good reproducebility. Chapter 4 A capillary zone electrophoresis with indirect LIF detection method is developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside).

第四章建立了一种毛细管区带电泳—间接激光诱导荧光检测法同时测定6种黄酮类化合物(秦皮甲素、秦皮乙素、异秦皮定、染料木素、柚皮苷和槐角苷)的新方法，扩大了LIF检测的应用范围。

In this study, we found that both naringin and quercetin promote the proliferation and differentiation of the osteoblasts.

研究发现：柚皮甙及槲皮素可促进骨母细胞的增生和分化，但在较高浓度下（10 mg/ml）对蚀骨细胞也呈促进作用。

Among these high value food ingredients citrus bioflavonoids, formerly known as "vitamin P"(hesperidin, naringin, diosmin, neoeriocitrin, and their respective aglycones, tangeretin, nobiletin, apigenin, luteolin or rutin, among others) have undergone increasing importance.

在这些高价值的食品配料中的柑橘生物类黄酮，以前称为&维生素 P &（橙皮苷，柚皮苷，地奥司明，新圣草苷，以及各自的苷元，桔皮素，川陈皮素，芹菜素，木犀草素或芦丁等）承载了越来越多的重要性。

Bitterness in citrus juice is primarily due to the presence of both limonin and naringin, and determination of them is a standard in controlling the quality of juice.

柑橘汁的苦味主要是由于柚皮苷和柠檬苦素的存在所致，其含量的测定可用于控制柑橘类果汁的质量。

In this way, about 50% of the naringin in orange juice can be degraded and about 20% of naringin in lemon juice can be degraded.But mainly bitter in citrus juice is limonin.

虽然能较好的降解柚皮苷，但是对苦味的影响不大，主要是因为柑桔汁中对苦味影响较大的是柠檬苦素。

Limonin and Naringin are the main bitters in citrus juice,so the citrus juice may become bitter.

柠檬苦素和柚皮苷等物质是柑橘类果汁中主要的苦味物质，果汁中因含有这类物质而具有苦味，因而会明显降低柑橘类果汁的口感和品质。

As results showed, for limonin and naringin, the linearity was good within the ranges of 1.00-50.00 mg/L (r=0.9992) and 20.00-160.00 mg/L (r= 0.9988) respectively, and the detection limits were 0.07 μg and 0.14 μg, then the average recoveries were 98.69% and 100.13% with relative standard deviations of 2.5% and 1.5%, respectively.

实验结果表明，柠檬苦素在1.00～50.00 mg/L时线性关系良好(r=0.9992)，检出限为0.07 μg，平均加标回收率为98.69%，相对标准偏差为2.5%；柚皮苷在20.00～160.00 mg/L时线性关系良好(r=0.9988)，检出限为0.14 μg，平均加标回收率为100.13%，RSD为1.5%。

Ursolic acid production, tanshinone Ⅱ A, resveratrol and glycosides, solanesol, luteolin, genistein and glycosides, naringin, lycopene, and so on a number of high-purity monomer plant compounds and Epimedium, rutaecarpine, green tea, grape seeds, small BAI Ju, Rhodiola, Zhishi, Trifolium pratense, Eucommia leaves, thorns Tribulus terrestris, hawthorn leaves, fungus activity polysaccharide, Hypericum perforatum, and other plant extracts of standards Exports to the Americas, Europe, Africa, Japan and other countries, product quality by international friends of praise.

生产的熊果酸、丹参酮ⅡA、白藜芦醇及苷、茄尼醇、木犀草素、染料木素及苷、柚皮苷、番茄红素等数种高纯度的植物单体化合物以及淫羊藿、吴茱萸、绿茶，葡萄籽，小白菊，红景天，枳实，红车轴草，杜仲叶，刺蒺藜，山楂叶，灵芝活性多糖，贯叶连翘等多种植物标准提取物出口到美洲、欧洲、非洲、日本等国，产品质量受到国际友人的广泛赞誉。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
