“…Also, we found no statistically significant differences between the acute pancreatitis and trimetazidine groups in terms of TNF-␣. High hepatic clearance of TNF-␣, the very short plasma half-life of 14-18 min [20] may explain this situation. Previously, remarkable TNF-␣ elevation was reported only in cases of severe/necrotizing acute pancreatitis [21].…”

“…The resin contains most of the compounds found in alcohol extracts consumed by people from many countries as food complements or alternative medicine. Propolis contains other constituents, such as pollen and amino acids (3,4). In their reviews, Marcucci (5) and Bankova et al .…”

Propolis is a hive product containing chiefly beeswax and plant-derived substances such as resin and volatile compounds. Propolis has been used as an antiseptic and wound healer since ancient times and interest for the product has increased recently. Probably few plant species contribute as major resin sources. Green propolis derives mainly from vegetative apices ofBaccharis dracunculifolia(alecrim plants). However, wide variation detected in the chemical composition suggests contributions from alternative resin plant sources. Predominant components of the resin of green propolis are cinnamic acids, chiefly compounds bearing prenyl groups. Terpenoid compounds, such as sesqui, di and pentacyclic triterpenoids, have been detected in many, but not all, samples investigated. Propolis research has uncovered potentialities of substances previously isolated from plants and has detected constituents of plant origin that would hardly be known otherwise.

“…Free amino acids (FAAs) are involved in the browning process that occurs during the commercial storage of food. The GC determination of FAAs has been described in bee-hive products other than RJ, such as honey (Pirini et al, 1992), propolis (Gabrys et al, 1986) and pollen (Serra Bonvehì, 1991). However, the quantitative determination of FAAs in RJ and their changes during storage have received little research attention due to the laborious sample preparation.…”

-Free amino acids (FAAs) in royal jelly (RJ) were determined and their identification was confirmed with mass spectrometric detection (GC-MS). The presence of D-aminoacids was evaluated using GC with a chiral column. The total FAA content was 7.3 mg/g RJ on average; the major FAAs were proline, lysine, glutamate, β-alanine, phenylalanine, aspartate and serine. The concentration of FAAs of the D-series was below the detection limit of the method (0.1 mg/g RJ) in all the samples. The FAA fraction was monitored in RJ frozen immediately after sample collection (control) and in aliquots of the same sample stored at two different temperatures (room temperature and 4 °C) for different time intervals (3, 6 and 10 months). The FAA content was constant throughout storage at 4 °C. However, at room temperature, proline and lysine increased after three months to 6.8 and 3 mg/g, respectively and then decreased after 6 and 10 months to 3 and 1 mg/g. royal jelly / free amino acid / storage condition / gas chromatography-mass spectrometry / chiral separation
