Abstract:
This paper deals with the determination of flavonoids and quality evaluation of Chinese
Typha. Four species, viz.
Typha angustata, T.angustifolia, T.davidiana and
T.latifolia and eight commercial samples of Chinese traditional drug “Puhuang” were collected. Five flavonoids in pollen, filaments, female flowers and leaves were determined by HPLC using
μ-Bondapak C
18 column, water—isopropanol—tetrahydrofuran=835∶14∶25, as mokile phase and detected at 287 nm). The qualities of different
Typha species and commercial “Puhuang” samples have been compared, and the criteria for their quality control were also discussed.
