Method for the Detection of Zeranol and SOP : ARO/442 Taleranol In
TITLE: Method for the detection of zeranol and S.O.P. : ARO/442 taleranol in meat and liver Page : 1 of 9 . Revision : 0 Date : 990715 1. INTRODUCTION 1.1 Summary This SOP describes a screening and confirmation method for the determination of resorcyclic acid lactones (RAL’s) in meat and liver samples of bovine origin. A procedure is described for the detection of a-zearalanol (zeranol) and b-zearalanol (taleranol) by a combination of solid phase extraction (SPE) and GC-MS. The method consist of, digestion of the meat sample using the enzyme protease and hydrolysis of the liver sample using suc d’Helix Pomatia, extraction of the RAL’s with tert-butylmethylether (TBME), purification using reversed-phase C18 cartridges. This method can also be used for the metabolites a-zearalenol, b-zearalenol, zearalanone and zearalenone. When doing so validation for these compounds is necessary. 1.2 Field of application The method is used to perform routine screening in meat and liver samples and has proven to be suitable for the analysis of a-zearalanol and b-zearalanol. The limit of detection is 0.5 mg/g based on the detection of the most abundant diagnostic ions namely m/z 433 and m/z 437 for the internal standard, with a response at the correct retention time exceeding the signal to noise ratio of 3. The method is validated according to SOP ARO/425 (1.3.3). 1.3 References 1.3.1. H.J. van Rossum et al, Multi residue analysis anabolic agents, SOP ARO/113, revision 4, 21 January 1997, RIVM. -

DIRECT ANALYSIS OF HOPS BY LEAF SPRAY AND PAPER SPRAY MASS SPECTROMETRY Kari Blain, M.S. Western Michigan University, 2012 The objective of this research is to develop a new and innovative method of hops analysis, which is much faster than standard testing methods, as well as reduce the amount of consumables and solvent used. A detailed discussion on the development of an ambient ionization mass spectrometry method called paper spray (PS-MS) and leaf spray (LS-MS) mass spectrometry will be presented. This research investigates the use of PS-MS and LS-MS techniques to determine the α- and β- acids present in hops. PS-MS and LS-MS provide a fast way to analyze hops samples by delivering data as rapidly as a UV-Vis measurement while providing information similar to lengthy liquid chromatographic separations. The preliminary results shown here indicate that PS-MS could be used to determine cohumulone and α/β ratios. -

The other annexes can be found in the following addenda: – Annex A: Add.1 – Annex B: Add.2 – Annex C: Add.3 – Annex E: Add.5 – Annex F: Add.6 – Annex G: Add.7 WT/DS320/R/Add.4 Page D-1 ANNEX D REPLIES OF THE SCIENTIFIC EXPERTS TO QUESTIONS POSED BY THE PANEL A. GENERAL DEFINITIONS 1. Please provide brief and basic definitions for the six hormones at issue (oestradiol-17β, progesterone, testosterone, trenbolone acetate, zeranol, and melengestrol acetate), indicating the source of the definition where applicable. Dr. Boisseau 1. Oestradiol-17β is the most active of the oestrogens hormone produced mainly by the developing follicle of the ovary in adult mammalian females but also by the adrenals and the testis. This 18-carbon steroid hormone is mainly administered as such or as benzoate ester alone (24 or 45 mg for cattle) or in combination (20 mg) with testosterone propionate (200 mg for heifers), progesterone (200 mg for heifers and steers) and trenbolone (200 mg and 40 mg oestradiol-17β for steers) by a subcutaneous implant to the base of the ear to improve body weight and feed conversion in cattle. The ear is discarded at slaughter. 2. Progesterone is a hormone produced primarily by the corpus luteum in the ovary of adult mammalian females. -

Campus de la Universidad Autónoma de Madrid, 28049 Madrid, Spain. * Corresponding author: [email protected] +34910017921 ACCEPTED MANUSCRIPT 1 ACCEPTED MANUSCRIPT ABSTRACT Hop (Humulus lupulus) is one of the richest natural sources of a prenylfalvonoids such as xanthohumol (XN), desmetylxanthohumol (DMX), isoxanthohumol (IX) or 8- prenylnaringenin (8-PN), being XN the most abundant of them in the raw material. So far, obtention of prenylflavonoids have been done by chemical synthesis or extraction with organic solvents, with no described methods for the isolation of IX, which has been reported to have anti-inflammatory properties. In this study, pressurized hot water extraction (PHWE) it is shown not only as effective method to extract some prenylflavonoids but to selectively change the relative amount of them, favoring the extraction of IX against XN. Thus, pressurized water extraction at 150ºC showed a high selectivity towards IX, being proposed as a method to enrich natural hop´s extracts in IX. On the other hand, the extracts thus obtained were chemically characterized and evaluated for their anti-inflammatory activity, which was higher than the expected by its content in IX.

October 2005) The effect of zeolite clinoptilolite (CLIN) on some metabolic parameters in blood serum and haematological values in weaned piglets fed with increased levels of zearalenone (ZEN) was investigated over a 14-day period. The research involved four groups of weaned piglets aged 40 to 54 days. All groups were fed on fodder mixture for growing pigs containing 20% crude protein and 12.57 MJ ME/kg. The first control group (C1) received a concentrate mixture without added ZEN or mycotoxin adsorbent Min-a-Zel Plus®. The second control group (C2) was fed on fodder mixture containing 0.2% of modified clinoptilolite (Min-a-Zel Plus®; levels of zearalenone <5.1 ng/g). Piglets in the experimental group (E1) were fed on fodder mixture containing added zeralenone (3 mg/kg) (Sigma-Aldrich Co) and 0.2% of Min-a-Zel Plus® preparation. The second experimental group (E2) was fed on fodder mixture to which 3 mg/kg of zearalenone was added, but with no addition of Min-a-Zel Plus®. Oestrogenic effect of ZEN was evident in the sinergistic action with insulin which was manifested in an increased total protein level, lower level of glucose, triacylglycerols, serum iron, a higer level of cholesterol and higher aminotransaminase activity. -
By Intestinal Microbiota; Conversion of Isoxanthohumol Into 8-Prenylnaringenin

Although a number of health effects are attributed to these compounds, only a few reports are available about the bioavailability of prenylflavonoids and the transformation potency of the intestinal microbial community. To test these transformations, four fecal samples were incubated with xanthohumol, isoxanthohumol (IX), and 8-PN. Upon incubation with IX, present in strong ales up to 4 mg/L, 36% was converted into 8-PN in one fecal sample and the estrogenic properties of the sample drastically increased. In an experiment with 12 fecal cultures, this conversion was observed in one-third of the samples, indicating the importance of interindividual variability in the intestinal microbial community. Eubacterium limosum was identified to be capable of this conversion (O-demethylation) of IX into 8-PN, and after strain selection, a conversion efficiency of 90% was achieved. Finally, strain supplementation to a nonconverting fecal sample led to rapid and high 8-PN production at only 1% (v/v) addition.
