Structure Determination of Compounds from the Bark of Ficus ingens (Miq.) Miq.

Abstract

This study was carried out to investigate chemical constituents on the bark of Ficus ingens (Miq.) Miq. Three compounds were isolated from methanol extract of the bark Ficus ingens (Miq.) Miq. and it were identified as compound-1 [tetrahydro-2-(hydroxymethyl)-6-(terahydro-3,4-dihydroxy-2,5-bis(hydroxymethyl)fura-2-yloxy)-2H-pyran-3,4,5 triol], compound-2 [dihydroxy-2-(3, 4, 5) trihydroxyphenyl) chromenylium-2-4) methoxy-6-methyloxane-3, 4, 5 triol] and compound-3 [6- methoxycyclohexane-1,2,3,4,5-pentaol]. The structures of the compounds were elucidated by means of ¹H-NMR, ¹³C-NMR and DEPT-135 spectral data and comparison with literature reports.
