Two New Triterpenoids from Lawsonia alba

Abstract

Two new triterpenoids, lawsowaseem and lawsoshamim, have been isolated from Lawsonia inermis and their structures established as 3β -hydroxy-24-p-E-coumaroyloxy-olean-12-en-28-oic acid, and 2-acetoxy-3β -hydroxy-olean-12-en-28-oic acid on the basis of spectral evidences, particularly 2D NMR studies.

An ancient plant Lawsonia inermis (henna): Determination of in vitro antifungal activity against dermatophytes species

“…The plant contains 25-33% water-soluble matter; aqueous solutions are orange in color and show a green fluorescence. The principal coloring matter is lawsone, 2-hydroxy-1,4-naphtoquinone, which is present in dried leaves in a concentration of 0.4-1.5% [2,11,26,28,29,33,34]. The two pentacyclic triterpenes, namely, 3b, 30-dihydroxylup-20(29)-ene (hennadiol) and (20S) 3b, 30-dihydroxylupane have been isolated from the bark [28].…”
