From the orchid, Arundina bambusifolia, were isolated two new stilbenoids, arundin and arundinin, besides p-hydroxybenzaldehyde, batatasin III, lusianthridin, flavanthrin, flavidin and the polyphenyl propanoid-malonate-derived compound 3,3′-dihydroxy-2,6-bis-(p-hydroxybenzyl)-5-methoxybibenzyl of previously known structures. Arundin and arundinin were shown to be 3-hydroxy-2,6-bis-(p-hydroxybenzyl)-5-methoxybibenzyl and 3,3′-dihydroxy-4-(p-hydroxybenzyl)-5-methoxybibenzyl, respectively, mainly from spectral evidence. |
