摘　　要：One new triterpenoid saponin, monepaloside K (1) was isolated from the water-soluble part of the whole plant of a famous Tibetan medicinal herb, morina nepalensis var. alba Hand.-Mazz.. Its structure was determined to be 3-O-a-L-arabinopyranosyl-(13)-b-D- xylopyranosyl siaresinolic acid on the basis of spectroscopic evidences, especially 2D NMR techniques.One new triterpenoid saponin, monepaloside K (1) was isolated from the water-soluble part of the whole plant of a famous Tibetan medicinal herb, morina nepalensis var. alba Hand.-Mazz..
