Tamariz. 2006.  C-26 and C-30 apocarotenoids from seeds of Ditaxis heterantha with antioxidant activity and protection against DNA oxidative damage.
J. Nat. Prod. 69(8): 1140-1144. 
The hexane extracts of seeds of Ditaxis heterantha afforded two new apocarotenoids whose structures corresponded to methyl 3-oxo-12'-apo-epsilon-caroten-12'-oate (1) (heteranthin) and methyl 3beta,6beta-epoxy-5beta-hydroxy-4,5-dihydro-8'-apo-epsilon-caroten-8'-oate (2) (ditaxin). Both compounds were evaluated for antioxidant activity and protection against DNA oxidative damage by using DPPH* free radical scavenging and Comet assays, respectively.
