Marketing and legal status of phytomedicines and food supplements in Morocco.

OBJECTIVES: The Phytomedicine (PM) and Food supplements (FS) Market is considerably growing in Morocco a review of state is necessarily to structure and improve it. METHODS: Information was collected directly from the pharmacist through a questionnaire-based survey who was conducted in 284 pharmacies in the region of Fez-Meknes in Morocco. Data were analyzed and classified using relative frequency of citations (RFC). RESULTS: More than 98% of the pharmacies commercialized the PM and FS, 80% of the pharmacists deny the existence of a real area dedicated to them, the majority (94%) of them prefer phytomedicine rather than classic drugs. This study reported about 64 products as the most used by the population of the region of Fez-Meknes among them 48 FS (75%) and 16 PM (25%) and the most marketed products are used for Transit Disorders (28.34%), then Anxiety (22.17%) and ENT Disease (20.18%). CONCLUSIONS: Despite the fact that Morocco is a country where people use medicinal plants daily, the commercialization of the PM and FS is still unstructured. Due to legal problem the PM Sold in the market are mainly exported. To assure development and also valorization of this sector the regulation of this market is highly required.

High Antioxidant Action and Prebiotic Activity of Hydrolyzed Spent Coffee Grounds (HSCG) in a Simulated Digestion-Fermentation Model: Toward the Development of a Novel Food Supplement.

Spent coffee grounds are a byproduct with a large production all over the world. The aim of this study was to explore the effects of a simulated digestion-fermentation treatment on hydrolyzed spent coffee grounds (HSCG) and to investigate the antioxidant properties of the digestion and fermentation products in the human hepatocellular carcinoma HepG2 cell line. The potentially bioaccessible (soluble) fractions exhibited high chemoprotective activity in HepG2 cells against oxidative stress. Structural analysis of both the indigestible (insoluble) and soluble material revealed partial hydrolysis and release of the lignin components in the potentially bioaccessible fraction following simulated digestion-fermentation. A high prebiotic activity as determined from the increase in Lactobacillus spp. and Bifidobacterium spp. and the production of short-chain fatty acids (SCFAs) following microbial fermentation of HSCG was also observed. These results pave the way toward the use of HSCG as a food supplement.

Efficient Binding of Heavy Metals by Black Sesame Pigment: Toward Innovative Dietary Strategies To Prevent Bioaccumulation.

Black sesame pigment (BSP) was shown to bind lead, cadmium, and mercury at pH 7.0 and to a lower extent at pH 2.0. BSP at 0.05 mg/mL removed the metals at 15 µM to a significant extent (>65% for cadmium and >90% for mercury and lead), with no changes following simulated digestion. The maximum binding capacities at pH 7.0 were 626.0 mg/g (lead), 42.2 mg/g (cadmium), and 69.3 mg/g (mercury). In the presence of essential metals, such as iron, calcium, and zinc, BSP retained high selectivity toward heavy metals. Model pigments from caffeic acid, ferulic acid, and coniferyl alcohol showed lower or comparable binding ability, suggesting that the marked properties of BSP may result from cooperativity of different sites likely carboxy groups and o-diphenol and guaiacyl functionalities. Direct evidence for the presence of such units was obtained by structural analysis of BSP by solid-state Fourier transform infrared spectroscopy and (13)C nuclear magnetic resonance spectroscopy.
