蓝靛果(Lonicera cearulea L.)是一种天然野生的可食用浆果,具有清除自由基、抑制炎症通路相关蛋白的磷酸化、抑制癌细胞增殖等生理活性,其抗氧化、调节血脂、抗肿瘤和防辐射等保健功效可应用于调节肠道菌群结构、抗癌、抗肥胖和保护视力等多个功能食品领域,且蓝靛果抗寒能力强,易于种植,具有极高的市场开发价值。研究总结整理了蓝靛果中活性化学成分(原花青素类、花青素类、花色苷类、黄酮类、有机酸类、多糖类及其它类化合物)的化学信息,归纳整理了不同类型化学成分的提取分离技术(溶剂提取法、酶解法、微波辅助提取法等),以期为蓝靛果深入研发及深加工产品的开发提供依据。 相似文献

Lonicera maackii (Caprifoliaceae) is a large, upright shrub with fruits that contain many bioactive compounds. Flavonoids are common active substances in L. maackii. However, there is a dearth of information about the accumulation of these flavonoids and their possible medicinal value. We used targeted metabolomics analysis based on ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to analyze five developmental stages of L. maackii fruit. A total of 438 metabolites were identified in the five developmental stages, including 81 flavonoids and derivatives. The 81 flavonoids included 25 flavones and derivatives, 35 flavonols and derivatives, two isoflavones, three cyanidins and derivatives, eight procyanidins, and eight flavanones. In addition, we outlined the putative flavonoid biosynthesis pathway and screened their upstream metabolites. More importantly, we analyzed the accumulation patterns of several typical flavones and flavonols. The results reported here improved our understanding of the dynamic changes in flavonoids during fruit development and contributed to making full use of the medicinal value of L. maackii fruit. 相似文献
