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

Triterpene saponins from the aerial parts of carnation (Dianthus caryophyllus var. remontant) 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 Trichoderma viride and the growth of the roots of Lepidium sativum and D. caryophyllus seedlings were measured. None of the isolated compounds showed pronounced activity in T. viride 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.
