Abstract

The polar fraction of the MeOH extract of the roots of Corrigiola litoralis subsp. telephiifolia (Pourr.) Briq. (Caryophyllaceae) was investigated for its constituents and two previously unreported monodesmosides triterpene saponins, telephiifoliosides A and B (1 and 2), along with the known bonushenricoside A (3) were isolated. Their structures were elucidated by combined spectroscopic and spectrometric techniques (1H NMR, 13C NMR, HSQC, 1H-1H COSY, HMBC, TOCSY, NOESY, HRESIMS) and chemical methods. The structures of the new saponins were established as; 3-O-α-L-arabinopyranosyljaligonic acid (1), and 3-O-α-L-arabinopyranosylphytolaccagenin ester (2). Upon evaluation of the antiproliferative activity on human malignant epithelial (HeLa) cells, none of the isolated compounds was efficient at the concentration of 33 µM. Highlights This is the first phytochemical study on Corrigiola litoralis subsp. telephiifolia. Two new saponins were isolated from the roots of Corrigiola litoralis subsp. telephiifolia. The isolated compounds were tested for their antiproliferative activity.
