Antimutagenic properties of a polyphenol-enriched extract derived from sesame-seed perisperm.
The physical strength of the endosperm, perisperm or seed coverings have been shown to restrict germination in cultivated crops like lettuce, tomato and cucumber (Dutta et al.
Buxbaum (1958) recognized four subtribes, particularly in the Cacteae tribe, based on seed morphology: Echinocactinae exhibits a perisperm and hard, black seed testas; Thelocactinae has black seed testas and a mostly warty surface; Ferocactinae exhibits dotted or reticulated seed testas; and Coryphanthinae has soft, smooth, and brown testas, similar to the Coryphantha and Mammillaria species studied herein.
2007) has found that a polyphenolic mixture derived from sesame-seed perisperm (SSP) exhibited desmutagenic activity against hydrogen peroxide, and benzo[a]pyrene in TA98 and/or TA100 and biomutagenic activity against sodium azide in strain TA100 of Salmonella typhimurium.
schidigera, also showing an organized dissolution of the perisperm cell wall close to the embryo.
2001) and the Cannaceae, Costaceae, Marantaceae and Zingiberaceae families would represent a unique clade, based on characters such as reduction of androecia to an only functional stamen, large and conspicuous staminodia, seeds with perisperm, absence of raphides in parenchymatic tissues and entire, firm and not torn leaves (Judd et al.
