Through the comparative studies of alkaloids, steroids, triterpenoids, cyanogenic
glucosides and fatty acids in the relevant orders of Monocotyledonae and “Nymphaeales”,and Ranunculaceae, the authors point out the close phylogenetic relationship between
the Ranunculaceae and Liliales. They support the hypothesis that Liliales, the oldest
primitive Monocotyledonae, was originated from Ranunculaceae, and they disagree
with the view point of Takhtajan who advocated that Alismales evolved from Cabom-baceae.
