Abstract:

The contents of hyperoside, isoquercitrin, rutin and total quercetin in different parts of Poacynum hendersonii
(Hook.f.) Woodson from Xinjiang were determined by high performance liquid chromatography (HPLC), and the total
flavoniods content was determined by spectrophotometry at 420 nm. The results showed that the total flavoniod content was
1.39% in leaves, 0.89% in flowers, 0.30% in roots, and 0.13% in stems. Among three major flavonoids identified in this
plant, isoquercitrin was the most abundant and showed detectable levels (0.4%, 0.15% and 0.07% in leaves, flowers and
stems, respectively) in all three other parts except for roots, along with very small amounts of hyperoside and rutin. The total
quercetin content in leaves and flowers was 0.63% and 0.34% by HPLC following acidic hydrolysis, respectively.

Key words: Poacynum hendersonii (Hook.f.) Woodson, flavonoid contents, high performance liquid chromatography (HPLC)
