title: Two new glycosides from Leonurus japonicus.
abstract: Two new glycosides, 1,6-di-O-syringoyl-β-D-glucopyranose (1) and quercetin 3-O-[(3-O-syringoyl-α-L-rhamnopyranosyl)-(1→6)-β-D-glucopyranoside] (2), along with seven known compounds were isolated from the MeOH extract of Leonurus japonicus. The structures of these compounds were elucidated by spectral analysis.
