خلاصه مقاله:
Lawsone, a natural pigment present in the henna leaves, has been used as a skin and hair dye since 1400 BC. The concentration of this natural compound in leaves varies from place to placedepending upon many of the environmental factors and the highest quantity reported so far is about 1% of the dry mass. Heretofore, it has been reported that natural colored extracts isolate from Henna leaves with many methods such as maceration, digestion, microwave and infusion. In this paper, regarding the therapeutic effects and traditional applications of henna, it was tried to isolate and characterize Lawsone from the henna leaves marketed in Tabriz city of Iran by soxhlet extraction technique in methanol solvent. The advantage of this technique is the isolation of large amounts of lawsone (720 mg from 40 g henne leaves powder) with smaller quantity of methanol.
