Fig. 1From: Triterpenoid profiling and functional characterization of the initial genes involved in isoprenoid biosynthesis in neem (Azadirachta indica)Skeletal diversity of Neem triterpenoids. Basic triterpenoids have azadirone, azadiradione, and gedunin type of skeletons. C- Seco triterpenoids have nimbin, salannin and azadirachtin type of skeletonsBack to article page
