Two new lignans, named (7R, 8 S)-balanophonin (1) and (7R, 8 S)-tomentosanan A (2), together with eight known lignans, burselignan (3), (+)-isolariciresinol (4), (+)-lyoniresinol (5), 5-methoxy-(+)-isolariciresinol (6), (-)-syringaresinol (7), (+)-epipinoresinol (8), (-)-(7′ S, 8 S, 8′ R)-4,4′-dihydroxy-3, 3′, 5, 5′-tetramethoxy-7, 9-epoxy-lignan-9′-ol-7-one (9), and (-)-(7 R, 8 S)-dihydrodehydrodiconiferyl alcohol (10) were isolated from the whole plants of Hedyotis uncinella Hook. et Arn. Structures of these compounds were elucidated through 1 H NMR, 13 C NMR, 2D NMR, ESI-MS and CD data.
