    摘要: It is intended to provide a process for efficiently producing a flavone C glycoside derivative represented by the formula (1) which is an antiallergic substance or its salt, or a flavone C glycoside derivative represented by the formula (4) or its salt. According to this process, the flavone C glycoside derivative represented by the formula (1) or its salt and the flavone C glycoside derivative represented by the formula (4) can be easily and efficiently synthesized by using isovitexine and vitexine contained in herbs and so on as the starting materials.
