Red sorghum (Sorghum bicolor) leaf sheaths as source stable pigments
摘要
Pigments are widely valued as colorants or bioactive agents in food, pharmaceutical, and cosmetic sectors. The increasing attention on the natural pigments can be associated with the availability, dietary, low-cost, bioactivity and safety. Sorghum bicolor is a common plant crop with many health benefits commonly. 3-deoxyanthocyanidin derivatives are the predominant anthocyanidins in the leaf sheaths of red sorghum. In this review, the phytochemical and nutritional properties of the leaf sheaths of red sorghum and the stability of the main pigments are discussed. In addition, the taxonomical and geographic distribution and traditional uses of the red sorghum are discussed. Anthocyanidins (luteolinidin, apigeninidin, apigeninidin-flavene dimer, apigeninidin-7-
