Abstract

Morphological characteristics and chemical composition of seeds of four species of Opuntia
genus endemic to the Samalayuca Valley were evaluated in this study. Morphology and
chemical composition of the four species were clearly different. Seeds of O. polyacanta var.
arenaria presented the highest values of area, length and width. However, O. phaeacantha
showed the highest values in palmitoleic acid (1.34 ± 0.12%), stearic acid (5.60 ± 0.47%), oleic
acid (19.42 ± 1.04%), alpha linolenic acid (2.42 ± 0.33%), arachidic acid (0.61 ± 0.11%), and
eicosenoic acid (1.74 ± 0.36%); but, this species showed the lowest values in linoleic acid
(54.35 ± 2.91 %) content. In conclusion, seeds of O. phaeacantha could be an important new
source of health-promoting polyunsaturated fatty acid, and its use in arid and semi-arid regions
should be encouraged.
