ISOLATION OF DIHYDROXYLUPENE AND DIHYDROXYLUPANE FROM THE BARK OF LAWSONIA INERMIS

Article abstract of DOI:10.1016/S0031-9422(82)85077-2

Two pentacyclic triterpenes isolated from the bark of henna were identified as 3β,30-dihydroxylup-20(29)-ene (hennadiol), and (20S)-3β,30-dihydroxylupane.The assignment of the C-20 configuration in the latter compound was supported by the analysis of Eu(fod)3-induced 1H NMR chemical shifts in the two C-20 epimers synthesized from lupeol. - Key Word Index: Lawsonia inermis; Lythraceae; henna; triterpenoids; 30-hydroxylupeol; 30-hydroxylupanol.
