使用

β-Apo-8'-carotenal is an antioxidant β-carotene (C184250) derivative found in Cucumis melo melons and traditional Portuguese fruits and vegetables. Studies have shown that β-Apo-8'-carotenal decreased the in vivo AFB1-induced DNA SSB and the binding of AFB1 to liver DNA and increased in vitro AFB1 metabolism to aflatoxin M1, a less genotoxic metabolite.

定義

ChEBI: An apo carotenoid triterpenoid compound arising from oxidative degradation of the beta,beta-carotene skeleton at the 8'-position.

一般的な説明

trans-β-Apo-8′-carotenal is a linear aldehydic carotenoid. It is naturally found in oranges, spinach, grass, tangerines and marigolds and thus, it is directly absorbed from the diet.

安全性プロファイル

When heated to decomposition it emits acrid smoke and irritating fumes.

純化方法

Recrystallise β-apo-8'-carotenal from CHCl3/EtOH mixture or n-hexane. [Bobrowski & Das J Org Chem 91 1210 1987, Beilstein 7 III 2622, 7 IV 1782.]
