Delayed action cytotoxins that inhibit the synthesis of nucleic acids. They are obtained from various molds/fungi (Aspergillus flavus, Aspergillus parasiticus). They are colorless to pale-yellow crystalline materials melting above 450°F. The "B" toxins fluoresce blue in the presence of UV light while the "G" toxins fluoresce green. They are only slightly soluble in water, but are soluble in methanol, acetone, and chloroform. Aqueous solutions are "probably stable" and "probably tolerant" to chlorine at purification concentrations. [Pg.479]

A limited degree of biolo ical control of the vectors of swollen shoot has been obtained by parasitizing the mealy bug vectors with Aspergillus parasiticus, according to a reference made by Chatt (10) to the work of Nicol, Owen, and Strickland. [Pg.23]

Aspergillus parasiticus is an endophyte isolated from the inner bark of the redwood tree. Sequoia sempervirens (Taxodiaceae). Previously, several sequoaitones active in the brine shrimp toxicity assay were isolated from this fungal strain and more recently four new sequoaitones C — F (49—52) were isolated and found to be toxic to brine shrimp with LD50 of260 p,M, 1300 xM, 640 xM, and 260 p.M, respectively. ...

Other naturally derived aflatoxin inhibitors obtained from the "neem" tree have been investigated in our laboratory (84), Azadirachta indica Juss. commonly known as "margosa" or "neem" is an ornamental tree of Asia and Africa that produces natural products having reputed value for their medicinal, antiviral, antibacterial, insecticidal, antifungal and antinematode properties (86, 87). Several active principles from different parts of the neem tree have been reported (88). Our investigation (84) examined the effects of these neem leaf components in neem leaves on aflatoxin biosynthesis by either Aspergillus parasiticus or A. flavus. [Pg.285]
