The aim of this study is to prompt the recovery of industrial byproducts through the production of new functional foods; it takes advantage from new throughput technologies with low environmental impact and high economic sustainability. In the field of fish processing, in order to recover the worthy protein-rich fish waste, residues from the production of Anchovies (Engraulis encrasicolus) have been converted into hydrolysate through

La canapa industriale è una pianta versatile e può essere utilizzata per scopi alimentari o
nutraceutici. Ogni parte della canapa può essere utilizzata nell'alimentazione (le foglie per la
preparazione di prodotti da forno: torte, pane, etc.; i semi per produrre olio commestibile e
farina). La farina di canapa contiene tutti gli otto aminoacidi essenziali ed è caratterizzata da
un rapporto di acidi grassi polinsaturi ω-3/ω-6, ottimale per la salute umana. La farina di

Metabolic profile of fresh turkey spermatozoa at three different reproductive period ages,
namely 32, 44 and 56 weeks, was monitored by Nuclear Magnetic Resonance (NMR) spectroscopy
and correlated to sperm quality parameters. The age-related decrease in sperm
quality as indicated by reduction of sperm concentration, sperm mobility and osmotic tolerance
was associated to variation in the level of specific water-soluble and liposoluble metabolites.
In particular, the highest levels of isoleucine, phenylalanine, leucine, tyrosine and

La carota (Daucus carota L.) è una radice della famiglia delle Apiaceae. È una delle colture vegetali più importanti e più economiche al mondo. Può essere consumata tal quale, sotto forma di succhi o essere la base di prodotti più elaborati. Dal punto di vista nutrizionale, le carote non apportano una quantità significativa di calorie (43 kcal per 100g), ma contengono numerose specie chimiche con documentate proprietà antinfiammatorie, antiossidanti, antimicrobiche, antivirali e antitumorali.

An undescribed labdane-like diterpene with a rare spiro-β-lactone function was identified from the ethanol
extract of the male cones of the coniferous tree Wollemia nobilis. This spirolabdadienolide (IUPAC name: syn-ent-
8(17),13-labdadien-19,18-olid-15-oic acid methyl ester; trivial name: wollemolide), was isolated by means of
traditional and high performance chromatography techniques and structurally elucidated through NMR and MS.
In addition, six further known metabolites were evidenced in the extract. Wollemolide, which may be considered

In this paper, the selective interactions of synthetic derivatives of two natural compounds, berberine and palmatine,with DNA G-quadruplex structureswere reported. In particular, the previous works on this subject concerning berberine were further presented and discussed, whereas the results concerning palmatine are presented here for the first time. In detail, these palmatine derivatives were developed by inserting seven different small peptide basic chains, giving several new compounds that have never been reported before.

In this work the HPLC and NMR analysis of the phenyl-ethanoid glycosides (PhGs) pattern of a cultivated exemplar of Verbascum thapsus L. (Scrophulariaceae) from the Etnean area (Sicily, Italy) was performed in order to verify their possible presence. Wild V. thapsus is well-known in ethnopharmacology due to the several beneficial effects that it is able to exert and which are primarily due to these compounds. So, it’s extremely important that also cultivated exemplars of this species biosynthesize them in order to maintain their pharmacological properties.

Verbascum thapsus L., commonly known as great mullein or common mullein, is a biennial herbaceous plant belonging to the Scrophulariaceae family [1].
It has a long tradition of use in ethnopharmacology since it is well know to posses several medicinal properties going from the expectorant and demulcent to the diuretic, anti-inflammatory, sedative, astringent, antiviral, antibacterial and antifungal ones and for these it has been long used in several parts of the world to treat respiratory problems as well as earache, eczema, hemorrhoids, diarrhea, fever, tumor and allergies [2].

Nine commercial hemp seed oils from different countries were studied using a multimethodological approach to obtain information about their quality and chemical composition. Due to the lack of a specific regulation for hemp seed oils, quality parameters used in the case of olive oils (free acidity, peroxides number, spectrophotometer parameters) and anisidine number were measured and compared with those reported for extra virgin olive oil (EVOO).
