The chemical composition, main physicochemical properties, and nutritional value of seed flour and seed oil ofLannea kerstingiiwere studied. The results indicated that seeds contained 3.61% moisture, 57.85% fat, 26.39% protein, 10.07% carbohydrates, and 2.08% ash. Potassium was the predominant mineral, followed by magnesium and calcium. The essential amino acids were at higher levels than the estimated amino acid requirements of FAO/WHO/UNU except for lysine. Fatty acid composition showed that oleic acid was the major fatty acid, followed by palmitic, linoleic, and stearic acids. Physicochemical properties of the seed oil were melting point, 19.67°C; refractive index (25°C), 1.47; iodine value, 60.72/100 g of oil; peroxide value, 0.99 meq. O2/kg of oil;p-anisidine value, 0.08; total oxidation (TOTOX) value, 2.06; oxidative stability index (120°C), 52.53 h; free fatty acids, 0.39%; acid value, 0.64 mg of KOH/g of oil; saponification value, 189.73. Total amount of tocopherols, carotenoids, and sterols was 578.60, 4.60, and 929.50 mg/kg of oil, respectively.γ-Tocopherol (82%), lutein (80%), andβ-sitosterol (93%) were the most abundant forms of tocopherols, carotenoids, and sterols, respectively. Seeds ofL. kerstingiiconstitute an alternative source of stable vegetable oil and protein for nutritional and industrial applications.

Foeniculum vulgare Mill. Commonly known as fennel has been used in traditional medicinal plant belonging to Apiaceae. The aim of this study was to examine quality and biological activities of fennel seed and leaf oils. The oil extraction was done in Soxhlet apparatus using hexane as a solvent.  The result for physicochemical properties presented significantly higher oil yield (4.39%) and peroxide value (3.90) was observed for seed oil. Significantly higher antioxidant activities with respect to DPPH (24.45±3.74) and hydrogen peroxide (62.70±0.28) free radical scavenging activities for leaf oil. However, ascorbic acid was found to be significantly higher for seed oil (82.44±4.63). The strongest antibacterial activity with maximum zone of inhibition (14.25mm), minimum inhibitory concentration (MIC, 0.25µl/ml) and corresponding minimum bactericidal concentration (MBC, 0.50 µl/ml) was recorded for leaf oil extract against Staphylococcus aureus. On the other hand, the strongest antifungal activity with maximum zone of inhibition (13.50mm), MIC (0.38µl/ml, the least value) and minimum fungicidal concentration (MFC, 0.75µl/ml) was recorded for leaf oil against Aspergillus Niger. It can be observed from the result in this study that leaf oil extract has demonstrated more effective biological activities including both antioxidant and antimicrobial potentials.

Potential Use

Propolis is a resin that honeybees produce by mixing saliva and beeswax with exudate gathered from botanical sources. The present in vitro study investigated the potential use of propolis as a multitarget therapeutic product and the physicochemical properties, chemical composition, and immunomodulatory, antioxidant, antibacterial, and anticancer properties of a propolis extract from the northern Morocco region (PNM). Pinocembrin, chrysin, and quercetin were the main phenolic compounds of PNM as measured in HPLC. The PNM showed significant inhibitory effects against all tested Gram-positive and Gram-negative strains and showed high antioxidant activities by scavenging free radicals with IC50 (DPPH = 0.02, ABTS = 0.04, and FRAP = 0.04 mg/ml). In addition, PNM induced a dose-dependent cytostatic effect in MCF-7, HCT, and THP-1 cell lines at noncytotoxic concentrations with IC50 values of 479.22, 108.88, and 50.54 μg/ml, respectively. The production of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) was decreased in a dose-dependent manner in LPS-stimulated human peripheral blood mononuclear cells (PBMNCs), whereas the production of the anti-inflammatory interleukin-10 (IL-10) was increased in a dose-dependent manner reaching 15-fold compared to the levels measured in untreated PBMNCs. Overall, the results showed that the traditionally known multitarget therapeutic properties of the PNM seem to be mediated, at least in part, through cytostatic, antibacterial, and immunomodulatory effects.
