Two New Bibenzyl Compounds from Dendrobium lindleyi

Özet

Two new bibenzyl compounds 4,4',5-trihydroxy-3,3',α-trimethoxybibenzyl (1) and 4,5-dihydroxy-3, 3',4',α-tetramethoxybibenzyl (2), along with seven known compounds (3–9), were isolated from the methanol extract of the whole parts of Dendrobium lindleyi. The chemical structures were established on the basis of spectroscopic analysis including one and two-dimensional NMR spectroscopy and comparison with previously reported data.
