Oleanene glycosides from seeds of Trifolium alexandrinum.
From the seeds of Trifolium alexandrinum, two new oleanene-type triterpene glycosides were isolated as their methyl esters, together with five known saponins. The structures of the isolated compounds were determined by NMR and mass spectral analyses.
