Phytochemicals analysis and aflatoxin B detoxification potential of leaves extract of and .

The present study aimed to identify the presence of certain classes of phytochemicals in the leaf extract of medicinal herbs viz. and , using qualitative detection tests and explored the potential of aqueous and ethanolic extract to inhibit aflatoxin production by thin layer chromatography at 25 °C and pH (7) of different incubation times i.e.

Effects of inoculation of corn silage with on silage fermentation characteristics, nutrient digestibility, mycoflora and aflatoxin production.

In the present study, fresh whole corn plants along with half milk kernels line were treated with live and hydrolysed yeast with different concentrations before ensiling and kept in airtight bags and then into mini silos in order to achieve anaerobic conditions for proper fermentation. The buckets were opened after different time intervals to characterise the material, quick acidification, dry matter recovery, and aerobic stability of silage respectively. Moreover, mycoflora and aflatoxin contamination were also analysed.

Light and scanning electron microscopic characterization of aflatoxins producing Aspergillus flavus in the maize crop.

Maize (Zea mays L.) is considered as one of the main cereals, used as a source of food, forage, and processed products. The loss of maize productivity is reported due to effect on roots, stalks, ears, and kernels mainly caused by many fungi.

Proximate composition, fungal isolation and contamination of aflatoxin B in chickpea seeds from the Punjab, Pakistan.

Chickpea, L., is a nutrient rich crop that is widely cultivated and consumed in Pakistan. However, chickpea is highly prone to fungal growth leading to contamination with aflatoxins, the most potent carcinogen found in nature.

Mycotoxins in , their quantification and HPLC analysis of physico-biological detoxification.

Present research delves in the isolation, extraction and identification of mycotoxins from ten corn samples collected from the northern province of Pakistan. Average concentration of aflatoxin B1 and B2 by HP-TLC found in all corn samples was 27.87 and 1.

Mycobiota Isolation and Aflatoxin B1 Contamination in Fresh and Stored Sesame Seeds from Rainfed and Irrigated Zones of Punjab, Pakistan.

Abstract: This study was carried out to evaluate the prevalence of mycobiota and aflatoxin (AF) B1 contamination in sesame seeds from rainfed and irrigated zones of the Punjab, Pakistan. For this purpose, 100 sesame seed samples were collected directly from the fields of major sesame-producing areas in rainfed and irrigated zones. The agar plate method was used for isolation of mycobiota, and thin-layer chromatography was used to determine AFB1 concentrations.

Analysis and quantification of naturally occurring aflatoxin B1 in dry fruits with subsequent physical and biological detoxification.

Current research involves extraction, identification and detoxification of mycotoxins from ten dry fruit samples. Mycotoxins were identified by high performance thin layer chromatography followed by physical and biological detoxification, analysed by HPLC. Three fungal species were observed after isolation including, and HP-TLC analysis revealed the presence of mycotoxin, aflatoxin B1 ranging from 0.

Report: Occurrence of Aflatoxin M1 in raw and processed milk consumed in Pakistan.

Aflatoxin M1 (AFM) is a hydroxylated metabolite of Aflatoxin B (AFB). It appears in milk, when lactating animals consume AFB contaminated feed. It is carcinogenic and teratogenic in nature.

Pre-harvest aflatoxins and Aspergillus flavus contamination in variable germplasms of red chillies from Kunri, Pakistan.

Various cultivars of red chilli were collected from a small town named Kunri, located in the province Sindh, Pakistan. This town is a hub of red chilli production in Asia. A total of 69 samples belonging to 6 cultivars were obtained and analysed for the occurrence of aflatoxins and Aspergillus flavus, to explore the potential of resistant and susceptible germplasm.

Dietary Exposure and Natural Occurrence of Total Aflatoxins in Basmati Rice of Pakistan.

This study presents the assessment of total aflatoxins (TAFs) in basmati rice (brown, 1,081; white, 1,170) collected from different areas of Punjab, Pakistan, during 2010 to 2015. Due to the carcinogenicity of TAFs, daily dietary exposure is also evaluated based on rice consumption survey data. Methodology was standardized by matrix spike recoveries at four fortification levels (0.

Reduction of ochratoxin A in broiler serum and tissues by Trichosporon mycotoxinivorans.

The present study was planned to evaluate the possible transmission of ochratoxin A (OTA) in serum and targeted organs of broilers fed on two levels (500 and 1000 ppb) this toxin in the presence or absence of a toxin deactivator (containing a mycotoxin deactivating yeast Trichosporon mycotoxinivorans) at two inclusion levels (1 and 2 kg/ton of feed) to 270 day-old broiler chicks divided into nine groups (A-I) over a 42 days period. Serum samples were collected at 14, 28 and 42nd day of experiment, whereas, liver and kidney tissues were obtained from broilers slaughtered at 42nd day of experiment. The highest OTA levels were detected in serum, livers and kidneys of OTA treated groups without supplementation of toxin deactivator (groups D and G) at day 42 of experiment, while the residues were significantly (P<0.
