Comparative analysis of some biochemical parameters of argan pulp morphotypes (Argania spinosa (L) Skeels) during maturity and according to the continentality in Essaouira region (Morocco)

Abstract

Argania spinosa (L.) Skeels is an endemic forest tree for Morocco. The phytochemical compounds evaluation of four different morphotypes of their fruit pulps was investigated. The total content of sugar, protein and phenolic compounds were monitored during three different stages of maturation in the semi-continental (Mejji) and littoral regions (R'zwa). Total sugars, proteins, phenolics increased up to the ripe stage of all argan fruit morphotypes in the two regions. Spherical shape had higher sugar and protein content than other morphotypes. A significant difference (p \ 0.05), was demonstrated by Pearson's test, between the different morphotypes at three stages studied for all the phytochemicals compounds. Likewise, ANOVA test established that the variation of this compounds was influenced by the stage of maturation and/or region of development and/or their interaction according to fruit shape. Results from this study revealed that the increase of these parameters level take place for the most part during the last stages of maturity which synchronize with fruit softening. Furthermore, our results showed information about the richness of argan fruit pulp in carbohydrates compounds and secondary metabolites as the possibility of their contribution in nutritive forage value especially at ripe stage.

Optimization of Bioethanol Production from Enzymatic Treatment of Argan Pulp Feedstock

“…Based on their results, the total sugar, reducing sugar, and phenolic compounds were 358.28–668.38 mg/g DW, 121.99–267.89 mg/g DW, and 74.37–101.24 mg EGA/g DW, respectively. Additionally, Zhar, et al [ 36 ] reported that the argan pulp spherical morphotype is very rich in sugar (85.5–353.33 mg/g FW) and the phenolic content became significant with the maturation for all fruit morphotypes.…”

Variation of biochemical content in the almonds of the endemic Argan tree (Argania spinosa (L.) Skeels) populations in Morocco

“…Generally, the maturation stage of argan fruits influenced significantly all biochemical compounds, and the maturation degree was positively and strongly correlated with all phytochemical compounds. In addition, the region had a significant effect on total protein (Zhar et al, 2016). The total proteins of all morphotypic argan fruit increased significantly and gradually from the green to the ripe stage (Zhar et al, 2016).…”

“…Sucrose, fructose, and glucose are reducing sugars produced by photosynthesis, which are important roles in regulating intracellular pressure, plant-water relations, transportation photoassimilates as well as protecting cellular membranes (Stitt et al, 2007). Zhar et al (2016) stated that the total sugar content of argan fruits with different morphotypes at different ripening stages in semi-continental and littoral regions shows significant variation. Generally, the ripe stage for all morphotypes is characterized by the greatest total sugar content values.…”

Agro-Fruit-Forest Systems Based on Argan Tree in Morocco: A Review of Recent Results

“…The fruits generally ripen between June and August, depending on the location and environmental conditions. The fruits of the argan tree exhibit various phenotypes ( Bani-Aameur et al, 1999 ; Bani-Aameur and Ferradous, 2001 ; Ait Aabd et al, 2011 , 2012 ; Zhar et al, 2016 ), being false drupes (according to Rammal et al, 2009 ) of size ranging from olive to walnut with different morphotypes (oval, rounded, and fusiform). The fruit of A. spinosa is very special; there is a hard stone (seed) under the fleshy pulp with 2–3 (or even 4 or 5) cavities containing false almonds (nuts).…”
