Sesamum radiatum exhibits a unique lignan profile.

(a) Sesamum radiatum flower (left) and capsule (right).

(b) High‐performance liquid chromatography (HPLC) chromatograms of S. radiatum and S. indicum seed extracts. UV absorbance was detected at 280 nm. Numbers next to peaks indicate lignans corresponding to those in (c).

(c) Major lignans that are generated in S. indicum and S. radiatum. Note that (+)‐7´‐episesantalin is a novel lignan identified from S. radiatum in this study (highlighted with a red number).

(d) Possible lignan biosynthetic pathway in S. radiatum. Dashed arrows indicate possible biosynthetic routes of lignans. SrCYP81Q2 responsible for (+)‐sesamin biosynthesis from (+)‐pinoresinol (Ono et al., 2006).
