he antimicrobial and antioxidant activities of crude ethanolic extract from Hippophaë rhamnoides
L. (Elaeagnaceae) leaf, stem, root and seed, and their respective
fractions, obtained by liquid–liquid extraction (LLE) using hexane (HF),
ethyl acetate (EAF) and water (WF), were investigated. The crude
extract was obtained by Pressurised Liquid Extraction (PLE), using
ethanol at 100 bar and 60 °C. Antimicrobial activity was tested against
food-borne and clinical microorganisms. Antioxidant activity was
measured using the DPPH-radical scavenging and the ferric reducing
antioxidant power (FRAP) assays. The phytochemical contents were
examined by colorimetric methods. The results showed that crude extracts
were active against Gram − and + strains, and that seed and root
extracts were better radical scavengers than leaf and stem extracts. For
all organs, the two activities tested were found to be higher in WF.
These activities were correlated with the presence of phenolic compounds
in active fractions. High Performance Thin Layer Chromatography (HPTLC)
fingerprints confirmed presence of phenolic compounds in active
extracts and fractions.

Sea buckthorn (Hippophaė rhamnoides L.), an ancient crop with modern virtues has recently gained worldwide attention, mainly for its nutritional and medicinal value as the berries contain different kinds of nutrients and bioactive compounds including vitamins, fatty acids, free amino acids and elemental components. This review briefly summarises the current literature and discusses its potential as a crop and its post harvest processing. The available compositional data regarding sea buckthorn berries is tabulated to produce a comprehensive source of recent information on chemical and medicinally important constituents of different origin and varieties. The presence of valuable chemicals and nutritionally important constituents in sea buckthorn berries, and from the scientific knowledge of their importance, it is clear that sea buckthorn berry is one of the most important sources of these constituents, and should be used as alternative nutritional sources in the commercial market. Similarly in depth investigation on the effect of processing on the total nutrient content of sea buckthorn berries species growing in different agro-ecological regions needs to be carried out. Thus, several important knowledge gaps identified in this paper would give impetus to new academic and R&D activities, in turn generating innovative job profile in food and cosmoceutical industries.

"L'argousier est considéré comme la prochaine génération de produits phytopharmaceutiques en raison de sa valeur médicinale considérable... Des recherches cliniques sur les usages médicinaux de l'argousier ont été entreprises en Russie dans les années 1950. En 1977, le ministère de la santé publique a inscrit officiellement l'argousier dans la pharmacopée chinoise, le reconnaissant ainsi comme plante médicinale."
