Triterpene saponins from the aerial parts of Dianthus caryophyllus var. remontant Hort.

Abstract

Triterpene saponins from the aerial parts of carnation (<em>Dianthus caryophyllus</em> var. <em>remontant</em>) Hort. have been studied. Three gypsogenic acid glycosides including 3-O-glucopyranoside, 3,28-O-di-glucopyranoside and 3-O-glucopyranosy1,28-0-[glucopyranosyl(1→6)glucopyranoside] have been identified by means of LSI mass spectrometry and 1H and 13C NMR. Inhibitory activities of isolated compounds against growth of the fungus <em>Trichoderma viride</em> and the growth of the roots of <em>Lepidium sativum</em> and <em>D. caryophyllus</em> seedlings were measured. None of the isolated compounds showed pronounced activity in <em>T. viride</em> test. Seedling root growth was affected severely at the presence of gypsogenic acid 3-O-glucopyranoside. Bidesmosidic form showed marginal stimulatory activity. The obtained data are discussed in relation to the activity of medicagenic acid 3-O-glucopyranoside, the compound differing just with 2-OH substitution from gypsogenic acid glycosides.
