Anthocyanin as a kind of natural pigment and high antioxidant active substance has excellent
health efficacy．Compared with aboveground organs，anthocyanin in root tubers and tubers，etc. underground
organs has the merits of high content，high yielding，easy for storage，and being an efficient，stable and
easy to use source of anthocyanin．Underground organs of colored potato，purple sweet potato and purple
Chinese yam，etc. plants are rich in anthocyanin．The paper summarized the anthocyanin synthesis in plants，
especially in underground organs，reviewed its regulation mechanism，and prospected the research emphasis in
the future．
