ChemotaxonomyPyrrolizidine alkaloids of Ipomoea hederifolia and related species☆
Three novel ipangulines (platynecine mono- and diesters) were isolated from I. hederifolia. A large series of related compounds were characterised by GC-MS in different parts of I. hederifolia, I. neei and I. x perigrenium.

2018, Alkaloids: Chemistry and BiologyCitation Excerpt :In the case of young plants of Heliotropium spathulatum, leaves are the main organs for the biosynthesis of necine, as demonstrated by exposure of the plant to 14CO2.187 For Ipomoea hederifolia (Convolvulaceae), the shoots are the site of PA biosynthesis.188 In PA-producing orchids, such as Phalaenopsis, these alkaloids are synthesized in young root tips and young flower buds.154
