Samples of crude- and refined- rice bran oil and de-oiled bran collected from mills and local market places were analysed for the presence of aflatoxins B1 and the causal fungi. Out of 20 crude rice bran oil and 20 refined rice bran oil samples analysed, 15 and 6 samples, respectively were positive for aflatoxins B1. The aflatxoin B1 in the rice bran oil samples were in the range of trace to 956 ppb and averaged 618 ppb. Out of 30 samples analysed, 20 samples of de-oiled bran were positive and the toxin level ranged from 7 to 144 ppb with an average of 33 ppb. The storage fungi including toxigenic fungi present in the rice bran oil and de-oiled bran samples were Aspergillus glaucus, flavus, A. niger, A . nidulans, A. candidus, A. fumigatus, and Penicillium spp. and Gliocladium viride. In the rice bran oil samples, the fungi found were less in number (1 one to 14 cfu/g) with an average of 2 cfu/g. While, in the de-oiled bran, it was 1 to 130 X 103 cfu/g with an average of 33 X 103 cfu/g which include toxigenic A. flavus. About 60% of A. flavus from crude rice bran oil samples and 66.7% of A. flavus strains isolated from de-oiled bran samples were positive for aflatoxin production.Keywords

Dried seeds of Cassia auriculata Linn., C.absus Linn. and C. fistula Linn. were collected from Javaathu hills, Tiruvannamalai District, Tamil Nadu, India for the comparative analysis of phyto-chemical potential with special reference to antioxidant activity. The active compounds were extracted with ethyl acetate, hexane and methanol. The methanol was found as suitable solvent and hence used for further extraction and analysis. The preliminary phytochemical screening of C. auriculata, C. absus C. fistula has revealed for the presence of alkaloids, phenolics and flavanoids in all the species. Absence of reducing sugars in C. absus, glucosides in C. auriculata and saponins in C. fistula were also observed. The quantitative determination of phenol and flavanoids was carried out in C. auriculata, C.absus and C. fistula and found that the total phenolic content as 0.18, 0.15, 0.11 and flavonoids 0.08, 0.092, 0.087% respectively. The antioxidant potential of the seed extracts recorded as much as 50% compared to α- tocopherol as standard. The Super oxide assay for the sample shows as 3% comparable to the standard α-tocopherol (5%). The Phosphomolybdenum assay and metal chelating activity indicate that the plant extract is a potential antioxidant. The details are presented in the present study.Keywords
