However, it is considered as underexploited specie despite its high potential to serve as source with economic and nutritional value. To date only limited information about its phytochemistry, especially of its oil has been published.
Species name :
This work provides data on fatty acids, phytosterols and vitamin D composition of L. It opens up new possibilities of developing L. The composition of fatty acids, phytosterols and vitamin D in L. The main fatty acids of L. Palimtic acid was present at low percentage 0. The content of unsaturated fatty acids was high as The sterolic fraction was composed of stigmasterol From these results it has been shown that L.
La composition en acides gras et en phytosterols des graines de Lycium intricatum Boiss. The fatty acid composition of oils from vegetable sources varies depending on plant origin, genetic factors, ripening grade of fruits and specific climatic conditions.
In addition to fatty acids, vegetable oils contain phytosterols which are divided into three main classes: The unsaponifiable fraction of vegetable oils contains a variety of bioactive substances, which include sterols, hydrocarbons, tocopherols, terpenes and others.
These minor compounds are more characteristic of each fat and oil [ 23 ]. Moreover, it has been reported that phytosterols, which represent the predominant portion of unsaponifiable matter, have multifunctional properties, including anti-inflammatory, antitumor, hypercholesterolemia, antifungal and antibacterial activities [ 4 — 6 ].
The genus Lycium Solanaceae family has been identified as a rich source of polysaccharidic, proteins and particularly glycopeptides, which are responsible for many health related benefits of this plant. The genus includes more than 70 species growing in temperate to subtropical parts of North and South America, Southern Africa, Eurasia, and Australia [ 7 ].
Among the chemical constituents of Lycium fruits, the most well researched components are anthocyanins and flavonoids [ 8 ]. In Tunisia, four Lycium species have been identified: It produces berries that are red when ripe.
It is used as a hedge and as wind break plant. In addition the dry powder of its fruit was used to protect from eye diseases. However, in Tunisia L. An improved knowledge about its chemical composition and biological activities would contribute to the use of this natural resource as a source of phytochemicals as well as to agronomic and economic advancement. To the best of our knowledge, although the potential beneficial effects of L.
The aim of this study was to determine for the first time the fatty acid composition and phytosterol content of L. The yield of seed oil of L. Linoleic acid is an essential fatty acid and a precursor of arachidonic acid biosynthesis, the substrate for eicosanoid synthesis. According to Keys et al. The content of unsaturated fatty acids was Our results are not in agreement with those published by Altintas [ 13 ] for L.
However, saturated fatty acids SFA fraction was characterized by a lower level 5. Recently, it was proven by clinical evidence that PUFAs are able to alleviate symptoms of certain diseases such as coronary heart disease, stroke and rheumatoid arthritis [ 14 ].
Also, linoleic acid has beneficial properties for skin, and for this purpose it is used by the cosmetics products industry [ 15 ]. These results bring attention to the possible use of cactus seed oil as a natural source of PUFAs for nutritional, industrial or pharmaceutical purpose. Indeed, different means are used to increase, directly or indirectly, the human consumption of PUFAs [ 16 ]. Oleic acid and linoleic acid exhibited contrasting accumulation patterns in L.
The percentage of linoleic acid was This is probably the consequence of an alteration of the desaturation step from oleic acid to linolenic acid, which is mediated by specific oleate desaturase enzymes. This is in agreement with the results obtained by Guoliang [ 17 ]. On the other hand, the higher content of unsaturated fatty acids The sterolic fraction was composed by stigmasterol Similar values were published by Potterat [ 10 ] for the sterol content in seed oil of two Goji species L. Recently, sterols have been added to vegetable oils as an example of a successful functional food [ 18 ].
In oil, Provitamin D was represented only by ergosterol. The Vitamin D level was higher in Inricatum. The high level of Vitamin D, detected in the oil, may contribute to great stability toward oxidation.
Ergosterol is the end product of the sterol biosynthetic pathway and is the major sterol in yeasts.
Like cholesterol in mammalian cells, it is responsible for membrane fluidity and permeability [ 20 ]. Previous works have been reported a role for ergosterol in physiological functions, such as membrane permeability, resistance to drugs, protein transport to the plasma membrane, sporulation and endocytosis [ 21 — intricathm ]. A relatively high content of triterpenes such as erythrodiol Das [ 24 ] reported that squalene, a hydrocarbon of lipid composition, exerted antioxidant effects used as food supplement and a vaccine additive.
A similar trend was also observed with hydrocarbons, mainly squalene; triterpenes such as uvaol, erythrodiol in Virgin olive oil [ intricstum ]. In fact, squalene administration modulates lesion development in a sex-specific manner and that it could be used as a safe alternative to correct hepatic steatosis and atherosclerosis, particularly in males [ 29 ].
Uvaol and erythrodiol exhibited antioxidant properties against lipid peroxidation in vitro, and also reduced the generation of hydrogen peroxide by stimulated macrophages in a dose-dependent manner [ 30 — 32 ].
These compounds have interesting therapeutic potential as cardiovascular drugs. The 4-desmethylsterols are the final products of the phytosterols biosynthesis; this category corresponds to plant sterols accumulated mainly in the fruit and seeds.

These compounds display anti-inflammatory properties and have long been lycuum to be the main active principle of Lycium sp [ 33 ]. This study shows that Lycium intricatum seed oil was found to possess Oil contained a higher amount of sterols. These results bring attention to the possible lyclum of Lycium seed oil as a natural source of PUFA for nutritional, industrial or pharmaceutical purpose.
This study helps to develop L. While there are no signs of toxicity of this plant, Tunisian peoples collect its fruits only in the full maturity stage to avoid risk of toxicity. So, fruits of L. The oil content was determined as the difference in weight of dried L. All the analyses were conducted in triplicate. FAMEs were analyzed by gas chromatography GC using a Agilent chromatograph series using a Innowax capillary column with the following characteristics: The ether extracted was dried over anhydrous Na 2 SO4 and evaporated.
The dry residues were dissolved in chloroform for TLC analysis.
On the basis of the reference spot, the sterols band was identified. The intrciatum corresponding to 4-desmethylsterols was scraped off separately and was extracted three times with CHCl 3 -Et 2 O 1: Phytosterols content was determined using gas chromatography. Louis, MO [ 35 ]. AB and AB have carried intrlcatum the experimental part such as selection of plant materiel, injections and identification of fatty acids and phytosterols. All authors read and approved the final manuscript.
