Chemical constituents from the aerial part of Peganum multisectum

Abstract Phytochemical investigation of the aerial part of Peganum multisectum led to the isolation of thirteen compounds, including seven alkaloids (1–5, 7 and 12), two sterols (6 and 10), one phenylpropanoid (8), one lignanoid (11), one megastigman (9), and one phenol (13). Their structures were identified by spectroscopic methods like UV, IR, MS and NMR, and in comparison with the published data in the references. Among them, compounds 10, 12 and 13 were firstly obtained from genus Peganum. The chemotaxonomic significance of these compounds was also discussed, which revealed the relationships between P. multisectum and some other species of genus Peganum.
