چکیده
By a screening program searching for new pesticides from fungal sources, an insecticidal compound was isolated from Penicillium citrinum F 1539. The compound, named quinolactacide, was novel and showed 88% mortality against green peach aphids (Myzus persicae) at 250 ppm. Its structure was determined by spectroscopic techniques.

Synthesis of quinolactacide via an acyl migration reaction and dehydrogenation with manganese dioxide, and its insecticidal activities.
Quinolactacide isolated from Penicillium citrinum F 1539 was synthesized and evaluated for its insecticidal activities. The key steps of the total synthesis were an acyl migration reaction of the enol ester intermediate and dehydrogenation of tetrahydroquinolactacide with manganese dioxide. The synthesized quinolactacide showed 100% and 42% mortality against the green peach aphid (Myzus persica...
متن کاملAlkaloids and polyketides from Penicillium citrinum, an endophyte isolated from the Moroccan plant Ceratonia siliqua.
The endophytic fungus Penicillium citrinum was isolated from a fresh stem of the Moroccan plant Ceratonia siliqua. Extracts of P. citrinum grown on rice and white bean media yielded five new compounds, namely, citriquinochroman (1), tanzawaic acids G and H (2 and 3), 6-methylcurvulinic acid (4), 8-methoxy-3,5-dimethylisoquinolin-6-ol (5), and one new natural product, 1,2,3,11b-tetrahydroquinola...

I t has been known for some time that Penicillium citrinum Thom when grown on suitable media produces a characteristic lemon yellow colour. Thus Thom in his monograph on “ Cultural Studies of species of 1910), says, “ P. citrinum produces a lemon yellow colour, soluble in alcohol, in media containing sugars, milk, gelatin, bread and potato.” This colouring matter was not isolated, however, nor ...
متن کاملQuinocitrinines A and B, new quinoline alkaloids from Penicillium citrinum Thom 1910, a permafrost fungus.
In the course of our previous work we isolated alkaloids such as agroclavine-I and epoxy-agroclavine-I from Penicillium citrinum VKM FW-800 as a microorganism isolated from permafrost1,2). This fungus was shown to coproduce two other alkaloid compounds, which were extractable only under acidic conditions. Positive staining by Dragendorff's reagent but negative Ehrlich reaction suggested the occ...
متن کامل(GTG)5 microsatellite regions in citrinin-producing Penicillium.
Morphological and cultural characteristics, as well as biochemical properties, are the main criteria used in fungal taxonomy and in the standard description of fungi species. Sometimes, however, this criterion is difficult to apply due to fungal phenotypic variations. This is particularly true in the genus Penicillium. The aims of this work were to determine (GTG)5 microsatellite sequence in po...
