Lawsonia inermis (Family: Lythraceae) contained carbohydrates, phenolic, flavonoids, saponins, proteins, alkaloids, terpenoids, quinones, coumarins, xanthones, fat, resin and tannins. It also contained 2-hydroxy-1,4-naphthoquinone (lawsone). Many alkaloids, naphthoquinone derivatives, phenolics and flavonoids were isolated from different parts of Lawsonia inermis. The pharmacological studies showed that Lawsonia inermis showed antibacterial, antifungal, antiparasitic, molluscicidal, antioxidant, hepatoprotective, central nervous, analgesic, anti-inflammatory, antipyretic, wound and burn healing, immunomodulatory, antiurolithiatic, antidiabetic, hypolipidemic, antiulcer, antidiarrhoeal, diuretic, anticancer and many other pharmacological effects. The current review will highlight the chemical constituents and pharmacological effects of Lawsonia inermis.Lawsonia inermis Linn (Family: Lythraceae) which is commonly known as henna, mainly present in subtropical and tropical areas and is used in all over the world. It was used for over 9000 y for its cosmetic values as a dye. The phytochemical analysis of Lawsonia inermis revealed the presence of carbohydrates, phenolic, flavanoids, saponins, proteins, alkaloids, terpenoids, quinones, coumarins, xanthones, fat, resin and tannins.

Plant profile
SynonymsAlcanna spinosa, Leaves of Lawsonia inermis provide an important cosmetic dye. Henna leaves were extensively used for centuries in the Middle East, the Far East and Northern Africa as dye for nails, hands, hair and textile. Henna was also used in treating skin problems, headache, jaundice, amebiasis and enlargement of the spleen [20,21].
Parts used medicinallyWhole plant, roots, fruits, stem, leaves, barks, inflorescence, rhizome, bulbs, latex, seeds, flowers and oil were used in different ailments [20].
Physiochemical characteristicsPhysiochemical investigation of leaf showed that the total ash was (14.60 %), acid insoluble ash (4.50 %), water soluble ash (3.0 %), loss on drying (4.5 %), alcohol soluble extractive value (3.8 % w/w) and aqueous extractive value (5.0 % w/w) [22].
Chemical constituentsThe preliminary phytochemical analysis of the aqueous extract of Lawsonia inermis revealed the presence of carbohydrates, phenolic compounds, flavonoids, saponins, proteins, alkaloids, terpenoids, 2 quinones, coumarins, xanthones, 6% fat, 2-3% resin and 7-8%...
