一般描述
类胡萝卜素是用于食品、动物饲料、保健品和制药行业的天然产品。α- 胡萝卜素，一种具有一个 β-环和一个 ε-环的类胡萝卜素， 普遍存在于食物中。橙色胡萝卜显示出高浓度的 α-胡萝卜素。
应用
α-胡萝卜素可作为标准品，用于使用高效液相色谱(HPLC)为 谷氨酸棒杆菌中类胡萝卜素定量。
生化/生理作用
α-胡萝卜素表现出维生素A原的活性。它可以作为比 β-胡萝卜素更有效的抑制剂，用于某些生长因子，如N-myc活性。α-胡萝卜素是水果和蔬菜摄入的良好生物标志物。高血清 α-胡萝卜素浓度与较低的心血管疾病(CVD)死亡率相关。

Aim of study was to find the most suitable LC column for generic carotenoid screening. To represent the diversity of carotenoids in nature and to optimize chromatographic separation, a set of carotenoid standards was carefully chosen to account for the
Human plasma carotenoid response to the ingestion of controlled diets high in fruits and vegetables.

Plasma carotenoid responses were determined in 36 healthy men and women before and after being fed controlled diets with a moderate amount of fat (26% of total energy) and a high carotenoid content (approximately 16 mg/d) for two 15-d periods.
