Two new dioxin derivatives from the aerial parts of Lawsonia alba

Abstract

From the aerial parts of Lawsonia alba two new dioxin derivatives, namely 12-[2′-(1′, 4′-dioxin-5′, 6′-dione)-8″E-undecenyl-dodecanoate (1) and 5-[1′-(docosa-2′E, 5′E-dienyl)]-1,4-dioxin-2,3-dione (2), were isolated and characterised on the basis of spectroscopic methods.

Keywords:

• Lawsonia alba
• Lythraceae
• dioxins
