New triterpenoids from Rubia cordifolia var. pratensis (Rubiaceae)[Reference: WebLink]
From the roots of Rubia cordifolia var. pratensis, three new triterpenoids named rubiprasin A, Rubiprasin B and rubiprasin C have been isolated and their structures were determined as 3β-acetoxyoleanane-13β, 15α-diol-12-one, 3β-acetoxyoleanace-13β-ol-12-one and 3β-acetoxyl-19α-hydroxyolean-12-en-28-oic acid respectively by various chemical and spectroscopic methods including 1H-1H COSY, 1H-13C COSY and X-ray diffractions.
