Cz. Wang et al., PHENYLPROPANOID, NEOLIGNAN AND IRIDOID GLYCOSIDES FROM PEDICULARIS-SEMITORTA, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(2), 1997, pp. 150-153
From the ethanolic extract of the whole plants of Pedicularis semitort
a, nine known glycosides, syringaresinol-4 ''-O-beta-n-monoglucopyrano
side, cistanoside D, cistanoside C, verbascoside, isoverbascoside, mus
saenoside, shanzhiside methyl ester, euphroside and aucubin along with
one new phenylpropanoid, cis-isoverbascoside and a mixture of erythro
- and threo-neolignans, named semitortoside A and semitortoside B, res
pectively, have been isolated. Their structures have been elucidated m
ainly by spectral evidence.
