隔离我²为黄色类胡萝卜素色素作为食品着色剂具有抗氧化化合物从Cucurbita moschata花

在当前的研究中,类胡萝卜素色素提取的花冠Cucurbita moschata食品着色剂使用丙酮和己烷具有抗氧化特性。纯类胡萝卜素是由水,盐水和溶剂清洗。这些类胡萝卜素提取被进一步用于薄层色谱分析。类胡萝卜素提取与β-胡萝卜素标准相比,与两位了。Rf值为0.786(暗橙色)和0.12(淡黄色)。抗氧化试验使用薄层色谱是利用DPPH法完成的。黄色和白色带形成证实,类胡萝卜素提取抗氧化剂。类胡萝卜素提取液的吸光度是扫描使用UV / VIS分光光度计和被发现有四个化合物为662.5,613.0,497.0和436.5海里。类胡萝卜素测试进行了相应的示例。丙酮失踪确认样品含有类胡萝卜素。 Two antioxidant activities were determined for the carotenoid extract. The Phosphomolybdenum method results with the 75.549% of antioxidant concentration and ferric ion reducing antioxidant power assay (FRAP) reveals with the 2.916% of antioxidant concentration. The carotenoid pigment not only plays a role in pharmaceutical, but also in neutraceutical applications. Thus the carotenoid content with antioxidant was detected by UV/VIS spectrophotometer and the compound was separated by column chromatography as food colourant.
