Abstract
Juglone is a naphtoquinone compound present in walnut (Juglans regia L. ; Juglandaceae ) leaves and peels.that have been broadly used in traditional medicine for many years. In this research, samples were collected during June to November 2001 and (10 g) extract with a Soxhlet apparatus for 2 hours. The concentrate of the acetone extract of the samples was defatted and then extracted with chloroform. The chloroform solution was evaporated under reduced pressure to give a dry residue recoverd by methanol. The extract was analysed by HPLC. Joglone content in leaves was from 0.021 mg/ml to 0.114 mg/ml and in peels were 0.035 mg/ml to 0.534 mg/ml , respectively.
