“…However, dietary inclusion of more than 20% SFM has been associated with a reduction in crude protein digestibility in Atlantic salmon , reflecting reduced digestibilities of most amino acids. This finding is consistent with reported effects of chlorogenic, caffeic and quinic acids that are known to interact and reduce the bioavailability of amino acids including lysine, cysteine, methionine (Pierpoint, 1970), alanine, phenyalanine and glutamic acid (Sripad et al, 1982).…”

“…As shown, the TPC content varied from 19 ± 3 to 107 ± 4 mg GAE/g and the highest amount was obtained with methanol followed by acetone for both seeds and peels fruits. The lower content of phenolic compounds in acetone extract compared to methanol may be explained by the low solubility of polyphenols in this solvent thanks to bonds hydrogen force between polyphenols and proteins (Sripad et al, 1982). For TFC, the lowest value was obtained for acetone extract in seeds.…”

Ecballium elaterium is a perennial herb with multiple medicinal properties. It was widely used in folk medicine as cathartic, anti-inflammatory and analgesic agents. The present study was devoted to investigate the effect of diethyl ether, acetone, and methanol solvent on the extraction, phytochemicals profiles, antioxidant and antimicrobial activities of Ecballium elaterium seeds and peels fruits. The total phenolic, flavonoid, flavonol, condensed tannins and carotenoids contents were estimated. Maximum phenolic (107 ± 4 mg GAE/g) and flavonoid (18 ± 0 mg QE/g) contents were also found in the methanol peels fruits extract. Results showed that methanol peels fruits extract have the highest antioxidant activity with IC 50 values of 1.2 ± 0.1 and 1 ± 0 mg/mL for DPPH and ABTS, respectively, and EC 50 value of 1040 ± 5 mg/mL for reducing power assays. Acetone and diethyl ether peels fruits extracts showed the best antibacterial agents especially against Micrococcus luteus, however no antifungal activity was observed. Spectral data of FT-IR analysis of Ecballium elaterium seeds and peels fruits extracts revealed the presence of functional groups such as ─DH, C─H, C─D and C=D. Due to their high antioxidant and antibacterial activities, E. elaterium seeds and peels fruits extracts have promising potential as future natural antioxidant and antibacterial agents in food industry.Keywords: Ecballium elaterium; solvent effects; phytochemical contents; antioxidant and antimicrobial properties; FT-IR analysis.Practical Application: Ecballium elaterium seeds and peels fruits can be potentially used as natural antioxidant and antibacterial inhibitor.

“…The low content of phenolic compounds in the aqueous extract of M. pubescens might be due to the presence of impurities (acid organics, glucides, proteins soluble) which can interfere in the determination of the phenolic compounds, Chirinos et al (2007) showed that the use of pure water as solvent of extraction leads to an extract with a high percentage of impurities. According to Sripad et al (1982), the lowest content of phenolic compounds noted in pure acetone could be due to a low solubility of polyphenols in this solvent thanks to bonds hydrogen force between polyphenols and proteins. Türkmen et al (2006), while studying the effect of different solvent on the extraction of phenolic compounds from black tea reported that water extracted polyphenols weaker than alcohol solutions.…”
