Phytochemical Investigation On The Leaves Of Dodonaea Viscosa Var. Angustifolia

The petroleum ether extract of the leaves of Dodonaea viscosa var. angustifoliarnafforded a diterpene 5-(2-(furan-3-yl)ethyl)-3,4,4a,5,6,7,8,8a-octahydro-8rnhydroxy-5,6,8a-trimethylnaphthalene-1-carboxylic acid (compound Dc-8B)rnwhereas the chloroform extract gave two compounds; a diterpene hautriwaic acidrn(compound D-16) and a flavonoid Santin (5,7-dihydroxy-3,6,4'-trimethoxyrnflavone) (compound D26-3B). Structural elucidation of these compounds werernconducted using 1H NMR, 13C NMR, DEPT, 2D NMR (COSY, HSQC, & HMBC), andrnUV-Vis spectra.
