Dynamic changes of flavonoids contents in the different parts of rhizome of Belamcanda chinensis during the thermal drying process.

ABSTRACT: The dried rhizome of Belamcanda. chinensis (L.) DC. is an important traditional Chinese medicine. Previous chemical and pharmacological investigations indicated that flavonoids may be responsible for the bioactivity of the herb. In this paper, the effects on the contents of twelve flavonoids in the three subunit parts of the rhizome of B. chinensis during the thermal drying process under treatment temperatures ranging from 40 °C to 120 °C at 10 °C intervals were investigated. The results showed that the content of most of the individual flavonoids except that of tectorigenin in the fresh eldest parts of the rhizome that originate directly from the seedling was higher than those of the other junior parts. The change trends of flavonoids contents were similar for three subunit parts of the r
