Diurnal change in rutin content in Capparis spinosa growing wild in Tafresh/Iran

Capparis spinosa has received considerable scientific interest in recent years, as it is as a source of a variety of biologically active compounds including flavonoids in special rutin. The present study was conducted to determine diurnal change in rutin content in different parts of C.spinosa at fresh fruiting stage. The plants were collected from Tafresh/Iran in August, after dissected into root, stem, leaf, floral bud, flower and fresh fruit they were dried at room temperature and subsequently assayed for rutin content by HPLC. Among different plant parts, floral buds and leaves were found to be the principle organ for rutin. Diurnal changes of rutin were also observed and slightly higher concentration of rutin in whole plant was observed in the morning.
