Overproduction of peroxynitrite ($ONOO^-$) causes a variety of disease such as atherosclerosis, hypercholesterolemia, diabetes mellitus or obesity. Peroxynitrite scavenging activities and HPLC analysis on the five Oriental medicinal drugs belonging to the genus Citrus, Aurantium or Poncirus (Rutaceae family) and HPLC analysis were taken to evaluate flavanone glycosides with peroxynitrite scavenging activity. The $IC_{50}s$ of the five crude drugs were shown as follows: Aurantii nobilis Pericarpium (Jinpi, 18.3 ${\mu}g$/ml), Citrii unshiu Pericarpium (Chungpi, 7.50${\mu}g$/ml), Citrii unshiu Semen (Gyulhaek, >50.0${\mu}g$/ml), Aurantii Fructus (Jigak, 18.3${\mu}g$/ml), and Poncirii Fructus (Jisil, >50.0${\mu}g$/ml) where Korean crude drug's names are noted in the parenthesis. Peroxynitrite scavenging effect of flavanones or their glycosides usually contained in Citrus species were observed as follows: hesperetin (1.89 ${\mu}g$/ml), naringenin (7.77 ${\mu}g$/ml), hesperidin (8.44 ${\mu}g$/ml), poncirin (>50.0 ${\mu}g$/ml)and ponciretin(>50.0 ${\mu}g$/ml). The activities of naringin and poncirin with ${\alpha}$-L-rhamnopyranosyl($1{\rightarrow}2$)-${\beta}$-D-glucopyranosyl moiety were weak. HPLC analytical data revealed that Jinpi (the peels of mature fruits of Citrus unshiu) and Chungpi (the peels of immature fruits of C. unshiu) had high quantities of hesperidin as the value of 142.1${\pm}$0.21 and 104.51${\pm}$1.10 mg/g dried weight, respectively. Poncirin was clearly detected in only Jisil and naringenin and naringin were not observed on the HPLC chromatogram of the five crude drugs.
