Deforestation is an important matter for the argan forest whose preservation necessitates planting trees. Macroscopic parameters are urgently needed to identify trees presenting good potential as oil producers. This study demonstrates that argan oil produced from kernels of apiculate fruit is richer in d-tocopherol, whereas oil produced from spherical fruit is richer in linoleic acid, and that produced from fusiform fruit is richer in oleic acid. Therefore, the use of fruit-form as a marker could permit an easy organic production of "naturally enriched" oils.
