Abstract


From the ethyl acetate and methanol extracts of the leaves and stems of Lumnitzera littorea (Jack) Voigt., collected in Thua Thien-Hue province, eleven compounds have been isolated. Their structures were elucidated as two resorcinolic lipids (1,3-dihydroxy-2-methyl-5-tridecylbenzene 1, 1,3-dihydroxy-5-nonadecylbenzene 2), two flavonoids (quercetin 3 and astragalin 4), two hexitols (1-acetyl-D-mannitol 5 and D-mannitol 6), α-D-glucopyranosyl-β-D-glucopyranoside (Neotrehalose 7) as octaacetate, fructopyranose as tetraacetate (8), β-sitosterol glycoside (9), β-sitosterol (10) and stigmasterol (11) as a mixture of 1:1 ratio. All of these compounds have been isolated for the first time from Lumnitzera littorea.

Keywords. Lumnitzera littorea, sterols, resorcinolic lipids, flavonoids, hexitols.
