Abstract:
Flavonoids are the most abundant constituents and induce these the rapeutic effects against inflammation, gastrointestinal infections, cardiovascular diseases, and respiratory. Most of these flavonoids have low content in Scutellarie Radix. It was difficult to detect some minor compounds by using LC-MS method with full scan. Based on the review of flavonoids that had been extracted from Scutellariae Radix, a method with PREC-IDA-EPI technique was developed and applied to Scutellariae Radix by using UPLC-MS/MS. A total of 97 flavonoids were identified, including 29 aglycones and 68 -glycosides. This study laid the foundation for pharmacodynamicss of Scutellariae Radix.It is believed that an individual detection scheme based on the PREC-IDA-EPI technique could be used to identify unknown compounds.
