title: Triterpenoid saponins from Dianthus chinensis.
abstract: Two novel triterpenoid saponins, dianchinenoside C [23-O-beta-D-glucopyranosyl 3 beta, 16 alpha-dihydroxyolean-12-ene 23 alpha, 28 beta-dioic acid 28-O-beta-D-glucopyranoside] and dianchinenoside D [3 beta, 16 alpha-dihydroxyolean-12-ene 23 alpha, 28 beta-dioic acid 28-O-beta-D-glucopyranosyl [1-->6)-beta-D-glucopyranoside] were isolated from the aerial parts of Dianthus chinensis. Their structures were determined by spectroscopic methods and chemical evidence. We also report the revision of a previous misassignment of hainanenside, isolated from Ilex hainanensis Merr. In addition, known compounds, 3-O-alpha-L-arabinopyranosyl hederagenin 28-O-beta-D-glucopyranosyl (1-->6)-beta-D-glucopyranoside, sitosterol 3 beta-O-beta-D-glucopyranoside, isoorientin-2"-O-glucoside, isovitexin-2"-O-glucoside, and chrysoeriol-7-O-glucoside, were also identified.
