Antifungal and antiaflatoxigenic assessment of new Cu(II)-pq complexes against Aspergillus parasiticus, in dark conditions and under visible irradiation.

The issue of food contamination by fungi and aflatoxins; constitutes a serious concern not only for human/animal health but also for agriculture and the economy. Aflatoxins are secondary metabolites produced by certain filamentous fungi and contaminate a variety of foodstuffs. In this context, control of fungal growth and aflatoxin contamination appears to be important.

Capsaicin, an inhibitor of Ochratoxin A production by section strains in grapes ( L.).

Food decay by spoilage fungi leads to significant economic losses and hazards to consumers' health due to the potential of mycotoxin occurrence. Ochratoxin A (OTA) is a mycotoxin known as nephrotoxic and carcinogenic to humans. Natural capsaicin was evaluated for its effectiveness against the growth of five section strains and accumulation of OTA in inoculated black grapes.

Comparison of Different Extraction Methods for the Determination of the Antioxidant and Antifungal Activity of Cynara scolymus and C. cardunculus Extracts and Infusions.

Extracts and infusions of wild artichoke (Cynara cardunculus L.) and globe artichoke (C. scolymus L.

Αntioxidant activity of Cynara scolymus L. and Cynara cardunculus L. extracts obtained by different extraction techniques.

Extracts of different parts (heads, bracts and stems) of Cynara cardunculus L. (cardoon) and Cynara scolymus L. (globe artichoke), obtained by two different extraction techniques (Ultrasound-Assisted Extraction (UAE) and classical extraction (CE)) were examined and compared for their total phenolic content (TPC) and their antioxidant activity.

Aflatoxin B1 in sesame seeds and sesame products from the Greek market.

Aflatoxin B1 (AFB1) is considered as the most potent liver carcinogen for humans. A method for determination in sesame seeds was developed. AFB1 was extracted by methanol-water, cleaned by immunoaffinity columns and determined by high-performance liquid chromatography with fluorescence detection.

Occurrence of aflatoxin B1 and ochratoxin A in dried vine fruits from Greek market.

Twenty-six samples of dried vine fruits from Athens and Thebes (Central Greece) market were simultaneously extracted and cleaned up by immunoaffinity columns and analysed for aflatoxin B1 (AFB1) and ochratoxin A (OTA). A combination of ELISA and HPLC methods was applied for the determination of AFB1. Recovery was 97.

Study of aflatoxin B1 production by Aspergillus parasiticus in bee pollen of Greek origin.

Aflatoxin B1 (AFB1) is a carcinogenic metabolite produced by certain Aspergillus species such as A. parasiticus and A. flavus.

Study of the Effect of Methyl Jasmonate Concentration on Aflatoxin B(1) Biosynthesis by Aspergillus parasiticus in Yeast Extract Sucrose Medium.

Aflatoxin B(1) (AFB(1)) is a carcinogenic metabolite produced by certain Aspergillus species on agricultural commodities. AFB(1) biosynthesis is affected by jasmonic acid and also by its methylester (MeJA), a plant growth regulator derived from linoleic acid. This study reports the effect of MeJA on the growth of A.

Determination of patulin in fruit juices using HPLC-DAD and GC-MSD techniques.

A high performance liquid chromatography with a diode-array detector (HPLC-DAD) and a gas chromatography with a mass spectrometer (GC-MSD) are described for the determination of patulin (PAT) in apple juice. The limits of detection (DL) and quantification (QL) for the HPLC-DAD and GC-MSD method were found to be (DL=0.23μgkg(-1) QL=1.

Determination of ochratoxin A in grapes of Greek origin by immunoaffinity and high-performance liquid chromatography.

A simple analytical method for ochratoxin A (OTA) determination in grapes is described, using aqueous methanolic extraction, an immunoaffinity column clean-up step and high-performance liquid chromatography with fluorescence detection. Mean recovery was 94% (RSD = 4.0%) with a detection limit of 0.

Study of aflatoxin B1 and ochratoxin A production by natural microflora and Aspergillus parasiticus in black and green olives of Greek origin.

Aflatoxin B1 (AFB1) is a carcinogenic metabolite produced by certain Aspergillus species. Ochratoxin A (OTA) is classified as "possible carcinogen" and it is a metabolite of Aspergillus ochraceus and Penicillium verrucosum. Fungi contaminate natural and processed olives which support AFB1 and OTA production.
