On the basis of these evidences and comparison with the spectral data of already reported compounds in the literature,  the compound was considered as a new taraxastene type triterpene
and hence the structure of 1 was assigned as 3-oxo-20(30)-taraxastene-28,13[beta]-olide.
More interesting, confidence intervals were smaller than for absolute concentrations in triterpenes
expressing a narrower range of values.
