B-크립토잔틴 C화학적 특성, 용도, 생산
화학적 성질
Garnet-red prisms with metallic luster. Soluble in chloroform, benzene, and pyridine; slightly soluble in alcohol and methanol.용도
A natural caratenoid pigment that is converted to Vitamin A in the human body. It is an antioxidant and may help prevent free radical damage to cells and DNA, as well as stimulate the repair of oxidative damage to DNA. A potential chemopreventative agent against lung cancer as well as other types of cancer.정의
ChEBI: A carotenol that exhibits antioxidant activity. It has been isolated from fruits such as papaya and oranges.일반 설명
β-Cryptoxanthin is an oxygen-containing carotenoid and is a member of the xanthophyll family. It is one of the major sources of vitamin A and is present in fruits such as oranges, tangerines and papayas. In addition, it is also found in corn, peas and some animal products such as egg yolk and butter.Purification Methods
Purify it by chromatography on MgO, CaCO3 or deactivated alumina, using EtOH or diethyl ether to develop the column. Crystallise it from *C6H6/EtOH (metallic prisms), or needles from *C6H6. Store it in the dark under N2 or Ar at -20o. The acetate has m 117.5o. The racemate is purified through a column of alumina (grade IV), eluted with *C6H6 then EtOAc/*C6H6 (1:9) and recrystallised from pet ether (b 60-80o) with m 172-173o. [Loeber et al.
