Flavone Glycosides from Lawsonia innermis

Chemical characterization and origin of dyes used in the manufacture of Beninese cultural heritage objects

“…Chromatographic analysis of sample S5 shows the presence of lawsone and apigenine ( t R = 22.5 minutes), both present in L. inermis (Figure B) …”

“…Concerning the sample S4, the chromatogram ( Figure 3A Chromatographic analysis of sample S5 shows the presence of lawsone and apigenine (t R = 22.5 minutes), both present in L. inermis ( Figure 3B). 5,21,22 It appears that lawsone is mainly characterized in samples containing red dye while blue samples are labeled with indigotin. Table 2 summarizes the main results of the different analyses.…”

Commercial Lawsonia inermis L. dried leaves and processed powder: Phytochemical composition, antioxidant, antibacterial, and allelopathic activities

“…For centuries, this plant was commonly associated to religious celebrations and wedding ceremonies, and had panoply of medical and cosmetic applications, as well (Zohourian et al, 2011). Particularly, henna leaves have been widely used as dye for hands, feet, hair, and textile (Afzal et al, 1980). It is applied to create designs on skin for temporary tattooing.…”

“…It is applied to create designs on skin for temporary tattooing. Moreover, henna has been proven able to treat skin maladies, headache and enlargement of the spleen (Afzal et al, 1980). In Tunisia, henna leaves are considered as an important source of cosmetic dye and used in folkloric medicinal therapy as infusion and decoctions (Ben Hsouna et al, 2011).…”

Luteolin as a potent anti-leishmanial agent against intracellular Leishmania tropica parasite

“…Flavonoids and alkylphenones are chemically well investigated, and a large number of member compounds have been reported. These include flavonoids and luteolin [14]; luteolin-4'-O-β-Dglucopyranoside [15]; apigenin 4-O-β-Dglucopyranoside [16]; apigenin [15]; xanhoangelol [8]; macaranggin [7]; artelastin [10]; 5,7-Dihydroxy-6,8-diphenyl flavonoids [11]; leachianone G [12] and alkylphenones such as Lalioside [17], 2,4,6-trihydroxyacetophenone-2-O-β-D-glucopyranoside [18] and lawsoniaside [19]. However, the current work deals with antileishmanial and cytotoxic effects of naturally occurring plant phenolic compounds having four flavonoids and one alkylphenone.…”
