ABSTRACT
In order to better utilize saffron floral bio-residues(SFB), a qualitative and quantitative analysis of flavonoids in SFB was conducted using UPLC-MS and UPLC, respectively. On the one hand, 50 flavonols and 5 anthocyanins were putatively characte-rized by using UPLC-Q-TOF-MS. On the other hand, an UPLC method was established for determining the fingerprint of SFB as well as testing the main flavonoids kaempferol-3-O-sophoroside and delphinidin-3,5-di-O-glucoside. Contents of kaempferol-3-O-sophoroside and delphinidin-3,5-di-O-glucoside of 10 batches of samples were 44.21-58.73 mg·g~(-1) and 2.11-6.37 mg·g~(-1), respectively, and the similarities of 10 batches were more than 0.99. In addition, the color of the samples was digitized by using electronic eye technology, and it was found that the color of the samples was significantly correlated with the content of delphinidin-3,5-di-O-glucoside. The richness of flavonoids in SFB indicated its potential for development and utilization, and the large variation in anthocyanin content among samples from different regions suggested that more attention should be paid to the methods of sample pretreatment and storage.
