Strigosa. This phytochemical study led to the isolation of nine pyrrolizidine alkaloids, from which three have been unidentified. ). In both Pulmonaria officinalis and Pulmonaria obscura such alkaloids as intermedine, lycopsamine and symphitine have been detected. This means that P. officinalis is not an exception among Boraginaceae in not having pyrrolizidine alkaloids, as had been previously claimed116 . 117 presented the evidence for this. Thus, they have advanced the theory of the botanical family base for alkaloid distribution.
