The so-called methoxychelidonine, an alkaloid isolated in 1924 from Chelidonium majus L. (Papaveraceae), is not an individual compound, but a mixture of three related alkaloids (+)-chelamine (III), (+)-homochelidonine (V) and (+)-chelamidine (IV) as it was deduced from high resolution mass spectral, thin-layer chromatographic and high-performance liquid chromatographic (HPLC) analyses of the authentic Gadamer's sample. The content of III, V and IV in "methoxychelidonine" found by HPLC technique was 67, 28, and 5 wt.%, respectively.

Wild neotropical blueberries, endemic of Central and South American areas, are promising yet still undisclosed sources of bioactive compounds. Most research studies have addressed wild and cultivated blueberries from Europe and North America, despite the extremely wide variety of wild neotropical species. In the present paper, for the first time, the phenolic composition of Disterigma alaternoides was investigated through ultra-high-performance liquid chromatography coupled to high-resolution mass-spectrometric analysis followed by accurate data analysis and compound validation with a dedicated structure-based workflow. D. alaternoides, which belongs to a closely related genus to that of the common blueberry, grows exclusively in the Andean regions over 2000 above sea level. Thanks to the dedicated analytical platform, 249 phenolic compounds were tentatively identified, including several anthocyanins, flavonoids, phenolic acids, and proanthocyanidins. Thenature and heterogeneity of identified phenolic compounds demonstrate once more the need for a more profound knowledge of such still uncharted matrices.
