General description

玉米黄素是一种类胡萝卜素，属于叶黄素类。作为 β-胡萝卜素的二羟基衍生物, 它存在于蔬菜和水果以及人的眼睛和皮肤中。 它具有抗氧化、抗炎、抗凋亡和神经保护特性。

Application

该分析标准品可用于以下应用：

  • 优化从玉米蛋白粉（corn gluten meal）样品中获取玉米黄素和叶黄素的超声辅助提取工艺以通过高效液相色谱-紫外可见光检测进行测定
  • 通过反相高效液相色谱（RP-HPLC）和紫外可见光检测器同时定量测定大豆粉中的五种类胡萝卜素和两种叶绿素
  • 通过超临界流体萃取、超临界流体色谱-大气压化学电离三重四极杆质谱 检测法（SFE-SFC-APCI/QqQ/MS）对完整人血样品中的类胡萝卜素和脱辅基类胡萝卜素（apocarotenoid）进行多残留分析
  • 高效液相色谱-二极管矩阵检测器（HPLC-DAD）法测定万寿菊花和食物增补剂样品中的类胡萝卜素
  • 采用 C30柱和光电二极管阵列（PDA）检测通过高效液相色谱（HPLC）分析不同植物组织样品中的类胡萝卜素及其异构体

Biochem/physiol Actions

类胡萝卜素色素有助于辣椒粉的颜色。玉米黄质在眼睛视网膜内积聚，并被认为可降低黄斑变性的发生率。

Packaging

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.

膳食抗氧化剂

抗氧化剂可保护生物系统免受含氧自由基和氧化还原过渡金属离子（如铁、铜和镉）引起的氧化损伤。

Due to excellent performance in antitumor, antioxidation, antihypertension, antiatherosclerotic and antidepressant activities, crocetin, naturally exists in Crocus sativus L., has great potential applications in medical and food fields. Microbial production of crocetin has received increasing concern in recent years. However

The macular region of the primate retina is yellow in color due to the presence of the macular pigment, composed of two dietary xanthophylls, lutein and zeaxanthin, and another xanthophyll, meso-zeaxanthin. The latter is presumably formed from either lutein or

The molecular mechanisms that allow pathogenic bacteria to infect animals have been intensively studied. On the other hand, the molecular mechanisms by which bacteria acquire virulence functions are not fully understood. In the present study, we experimentally evaluated the evolution
