• Dendrophthoe pentandra
• Loranthaceae
• Furan-2-carbonyl C-glucoside scleropentaside F
• Alkyl glucoside

A new furan-2-carbonyl C-(6'-O-galloyl)-beta-glucopyranoside (scleropentaside F, 1) and a new alkyl glucoside [butane-2,3-diol 2-(6'-O-galloyl)-O-beta-glucopyranoside, 2] were isolated from the entire hemi-parasitic plant, Dendrophthoe pentandra growing on Tectona grandis together with ten known compounds including, benzyl-O-beta D- glucopyranoside (3), benzyl-O-a-L-rhamnopyranosyl-(1. 6)-beta-D-glucopyranoside (4), benzyl-O-beta-D-apiofuranosyl-( 1. 6)-beta-D-glucopyranoside (5), methyl gallate 3-O-beta-D-glucopyranoside (6), methyl gallate 3-O-(6'-Ogalloyl)- beta-D-glucopyranoside (7), (+)-catechin (8), procyanidin B-1 (9) and procyanidin B-3 (10), bridelionoside A (11), and kiwiionoside (12). In addition, compounds 1, 3-9 were isolated from this species growing on the different host, Mangifera indica. The structure elucidations were based on physical data and spectroscopic evidence including 1D and 2D experiments.
