Another example could involve searching for the presence of a specific compound of pharmaceutical interest to identify potential biological sources. As an example, the ions for celastrol (Q5057534) were queried in MassQL. The results showed the presence of several precursor ions with a particular MS 2 fragment at m/z 201.09, characteristic of the quinone methide triterpenoids . Several extracts were highlighted for their celastrol content (check the Dashboard comparison). This information enables the contemplation of these sources as potential candidates for isolating the target metabolite and its analogs. Incorporating CAD traces in the provided raw data facilitates a more informed choice when selecting an extract, as it provides a more accurate representation of the NE's real composition.
